Abstract:This paper investigates the bond-slip behaviour of steel reinforcement embedded in engineered cementitious composites (ECC), a ductile concrete exhibiting tensile strain hardening performance. Two series of experimental tests were carried out on short and long reinforcement subject to pull-out actions. The maximum bond stress that embedded steel reinforcement could sustain was quantified through pullout tests on short rebars. Experimental results of short reinforcement suggested that ECC significantly increased the maximum bond stress of steel reinforcement. For long reinforcement, special attention was paid to the bond stress of steel segments at post-yield stage. Bond stress profiles were determined in accordance with attached strain gauge measurements along the steel bars. Besides, the effect of localised necking beyond ultimate strength on the force-slip relationships of reinforcement was studied. Thereafter, an analytical model was proposed based on experimental results to predict the force-slip relationship of long reinforcement either anchored in concrete or in ECC. Reasonably good agreement was achieved between experimental and analytical force-slip curves. Finally, parametric studies were conducted to quantify the required embedment length of steel reinforcement in ECC.

Keywords-:Bond-slip behavior, ECC significantly, analytical force-slip curves.

Abstract:- Slopes and retaining walls are widely used for roads, railways, river training works, canal works, dams etc. The economy and safety of these earth-retaining structures can be accomplished by adopting proper methods of design, construction and maintenance. The failure of these structures is likely to result in huge loss of life and damage to property. In the present work, an attempt has been made to estimate the permanent displacement of the slopes and retaining walls from pseudo static approach. MATLAB is used as a tool and programs are developed. To evaluate permanent displacement of slopes and retaining walls considering factors such as height of slope, inclination of slope, cohesion of soil and density of soil. Newmark's method, the popular method of analysis has been used and parametric studies have been carried out. To calculate permanent displacement of retaining walls, Richards-Elms method has been adopted. In addition, Newmark's method has been modified to suit the requirements of retaining walls. The present work has been carried out in three stages. In the first stage, a program has been developed in MATLAB to evaluate the permanent displacement of slopes using Newmark's approach. For this purpose, pseudostatic analysis has been carried out considering the effect of height of slope, inclination of slope, cohesion of soil, density of soil on the yield acceleration. The effect of input motion on the permanent displacement has been brought out by considering different earthquake motions, In the second stage of work, importance is given to the development of a computer program for the evaluation of permanent displacement of retaining walls using Richards-Elms approach. For this purpose, yield acceleration that develops under the given soil properties, mobilized earth pressure and geometry of retaining wall were determined by iterative procedure. A parametric study has been made to consider the effect of various factors influencing the permanent displacement of retaining walls such as geometry of wall, properties of backfill soil, condition of soil and soil and wall interaction angle In the last stage, an attempt has been made to modify the Newmark's approach to suit the retaining wall problem. For this purpose, a combination of analysis using Richards-Elms method to calculate yield acceleration and Newmark's method to estimate permanent displacement from the data of earthquake motion and yield acceleration as in the analysis of slopes has been incorporated. A comparison is made with Richards-Elms approach. From the present work, it has been brought out that Newmark's method gives more realistic results as Richards -Elms approach is an empirical relation and Newmark's approach considers the region of the earthquake motion above the yield acceleration more accurately.

Abstract: Bridges play a significant role in transport connection as they ensure continuous transportation network between two inaccessible vicinity. During the period of natural disaster such as earthquakes, it provides an emergency services like supply of food, medicines etc.; hence, the bridges are lifeline structures. Bridges are very susceptible to ground motions due to simplicity in their construction; hence they are prone to damage and even collapse completely. "The general earthquake design principle is to design a structure to prevent complete collapse in case of strong earthquake ground motion". The resistance of structure to earthquake can be ensure either by building structural member strong enough so that it is capable to resist earthquake excitation or by use of dampers or by employing base isolation systems. Among these, base isolation is gaining significant popularity in the recent years. So far, the performance of bridges under seismic loads has been evaluated by many with different isolators at the junction of the bridge deck and the top of pier cap. But very less such information is available for the seismic performance evaluation of bridges with base isolation at the foundation level. Hence the objective of this study is to assess the seismic performance of an RC bridge with three different types of isolators (ie., Lead Rubber Bearing, High Damping Rubber Bearing and Friction Pendulum System) at the bottom of the bridge piers.

Abstract:- Concrete is made by combining cement, water, and aggregate (coarse and fine) materials such as gravel and sand. Water is required to react with the cement in order for the hydration process to commence. Water is thus one of the most significant ingredients in the manufacturing of concrete. The physicochemical properties of cassava effluent and water polluted with cassava effluent were taken to the KAPPA Biotechnology Laboratory in Ibadan, where various elements present in the samples such as cyanide, cadmium, magnesium, calcium, copper, iron, and lead, among others, were analysed and compared to WHO standards. Slump, compaction factor, compressive strength, and split tensile tests were performed on concrete mixed with potable water and cured in potable water (A); concrete mixed with potable and cured in cassava effluent (B); concrete mixed with cassava effluent and cured in cassava effluent (C); concrete mixed with cassava effluent and cured in potable water (D); concrete mixed with polluted water and The findings revealed that cassava effluent and water polluted with cassava effluent have no discernible effect on the workability of concrete made with them when compared to concrete made with potable water; however, concrete made/cured with cassava effluent and water polluted with cassava effluent had lower strength in mixing and curing when compared to those made with potable water. Based on the decrease in the values of the Slump, Compacting factor, Compressive strength, and Split tensile strength of concrete made with either cassava effluent or water polluted with cassava effluent in mixing or curing, it can be concluded that cassava effluent or water polluted with cassava effluent should be discouraged for mixing or curing of concrete as these will have negative effects on such concrete.

Abstract:- Construction expenses in India are growing at a rate that is about 50% faster than inflation. It has risen by up to 15% every year, owing mostly to rising prices for basic construction materials such as steel, cement, bricks, timber, and other inputs, as well as labour expenses. As a result, traditional building materials and construction are becoming costly, particularly for low-income and a large segment of the middle-income population. As a result, cost-effective building methods must be used, either via the improvement of traditional technologies utilising local resources or by the employment of modern construction materials and processes with efficient inputs leading to economic solutions. Because of the large number of houses to be built in both rural and urban areas, as well as the limited resources such as building materials and money, this has become the most crucial component. This article offers an overview of the housing issue in India as well as the country's adoption of relevant and cost-effective technologies.

Abstract:- This paper presents an investigation on innovative optimum, Self-compacting concrete (SCC) can produce much higher fluidity with no occurrence of segregation, thanks to its lower yield value and higher viscosity than conventional concrete. Increased productivity and improved working environment have had high priority in the development of concrete construction over the last decade. The casting process creates a significant amount of waste foundry sand (WFS). Using WFS as a concrete ingredient reduces the problems associated with the dumping process of these types of wastes, removes/reduces carbon dioxide, and is also considered economical in terms of overall concrete production cost. . Hence, predicting the behavior of concrete using the development of models based on artificial intelligence (AI) algorithms derived from the laboratory data can remarkably improve the project’s efficiency in terms of cost and time. This paper assessed the performance of artificial neural networks (ANNs) to predict the strength parameters of concrete containing WFS (CCWFS). In this regard, a comprehensive laboratory database consisting of 102, 397, 146, 346, and 169 data for the slump, compressive strength, elasticity modulus, splitting tensile strength, and flexural strength of CCWFS were collected from literature, respectively.

Abstract:- In India, the usage of industrial waste in different engineering projects has become popular. This is required because of the disposal issues involved. Copper slag and silica fume are two of the most often used waste products in the building sector today. Large amounts of these wastes are gathered and deposited on expensive land, resulting in the waste of good cultivable land. Mixing these wastes with existing soil types without entirely removing and replenishing with another soil type can be an inexpensive option for cement mixing and soil stabilization. This study presents a review of existing research studies on the effective use of copper slag and silica fume conducted by various scholars.

Abstract:- Concrete is a popular building material, and the construction industry is constantly expanding its usage and applications; thus, it is vital to discover alternative materials to minimise the cost of concrete supplies. Natural coarse aggregate, on the other hand, is mined from quarries, and as a result, these quarries will be depleted in a few decades if the pace of their usage continues at present rate. As a result, a lasting solution to this problem was required. The disposal of tyre elastic or shattered blocks for the production of cement has been considered as an alternative transfer of such waste to protect the environment. In this study, tyre rubber and broken bricks were employed as coarse material, with a 30 percent substitution for conventional aggregate. The compressive strength of concrete was measured at 7, 14, and 28 days, and a comparison between waste tyre rubber and waste broke brick was performed. After a 28-day comparison, the waste material with the highest strength is chosen as the best waste material replacement with aggregate.

Abstract: Seismic-resistant design has become a pivotal component in modern civil engineering, particularly for structures located in seismically active regions. The integration of base isolation and tuned mass dampers (TMDs) offers a transformative approach to minimize structural vibrations and enhance safety. Base isolation systems function by decoupling the superstructure from ground motions, significantly reducing energy transfer during seismic events. Meanwhile, TMDs counteract vibrational energy by using a secondary mass-spring-damper system tuned to the structure’s natural frequency. This paper explores the fundamentals, applications, performance advantages, and future potential of combining base isolation with TMDs. It highlights real-world case studies and experimental results demonstrating improved damping, cost-effectiveness, and resilience of hybrid systems. As seismic design criteria become more rigorous, the synergy between these technologies can revolutionize how urban infrastructure is protected against earthquakes.

Abstract: In India, the usage of industrial waste in different engineering projects has become popular. This is required because of the disposal issues involved. Copper slag and silica fume are two of the most often used waste products in the building sector today. Large amounts of these wastes are gathered and deposited on expensive land, resulting in the waste of good cultivable land. Mixing these wastes with existing soil types without entirely removing and replenishing with another soil type can be an inexpensive option for cement mixing and soil stabilization. This study presents a review of existing research studies on the effective use of copper slag and silica fume conducted by various scholars.

Abstract: Concrete is a popular building material, and the construction industry is constantly expanding its usage and applications; thus, it is vital to discover alternative materials to minimise the cost of concrete supplies. Natural coarse aggregate, on the other hand, is mined from quarries, and as a result, these quarries will be depleted in a few decades if the pace of their usage continues at present rate. As a result, a lasting solution to this problem was required. The disposal of tyre elastic or shattered blocks for the production of cement has been considered as an alternative transfer of such waste to protect the environment. In this study, tyre rubber and broken bricks were employed as coarse material, with a 30 percent substitution for conventional aggregate. The compressive strength of concrete was measured at 7, 14, and 28 days, and a comparison between waste tyre rubber and waste broke brick was performed. After a 28-day comparison, the waste material with the highest strength is chosen as the best waste material replacement with aggregate.

Abstract: The rapid depletion of natural resources and increasing environmental concerns have necessitated sustainable approaches in infrastructure development, especially in the construction of pavements. This paper focuses on two environmentally friendly pavement technologies—Recycled Pavements and Permeable Pavements. Recycled pavements utilize reclaimed asphalt and concrete materials, significantly reducing the consumption of virgin aggregates and energy. Permeable pavements, on the other hand, allow stormwater infiltration, reducing runoff and promoting groundwater recharge. These technologies, when applied effectively, not only minimize environmental impact but also offer economic and structural benefits. The paper evaluates materials, design considerations, benefits, limitations, and future directions for both types of sustainable pavement systems.

Abstract: Concrete is a composite material used in construction. Next to water, concrete is the most used material worldwide for construction of any desired shape or different structure. Concrete has low strength, low ductility and energy absorption. Different concrete require different degrees of durability depending on the exposure environment and properties desired. Concrete ingredients, their proportioning, placing and curing practices, and the service environment determine the ultimate durability and life of concrete. For this purpose to improve the concrete toughness and reduce the amount of defects by adding a some fibers to the concrete for this situation SIFCON type concrete is preferred and the fiber are uniformly distributed and it is different from fiber reinforced concrete (FRC). Slurry-infiltrated fibrous concrete (SIFCON) can be considered as a special type of fiber concrete with high fiber content. The fiber content of FRC generally varies from 1to3 percent by volume, but the Fiber content of SIFCON varies between 5 and 20 percent. The network is then infiltrated by a fine liquid cement-based slurry or mortar. It is not having coarse aggregate only have cement and sand or any cementitious material. In view of the above, the objectives of this study are to investigate and provide information about strength of SIFCON, mainly resistance to abnormal loads, impact loads and earthquake loads. Here straight stainless steel and E type glass fiber are used with different volume of fraction, i.e. 6%,8%,10%,12% and cement, sand, fly ash are used 1:1:0.5. The compressive strength of SIFCON is increased 26% when comparing to M30 concrete.

Abstract: This paper reports the results of experimentsevaluating the use of natural product as partial replacement for ordinary Portland cement in concrete. While concreting is done the main ingredients are coarse aggregate, fine aggregate, cement and water. Out of these cement has more demand and if we can replace it with another natural product which is economical, it may become a great success. We choose tapioca powder for partially replacing the cement in concrete. We founded an optimum percentage of 1.0 for partially replacing the cement by tapioca powder in concrete, through which we can achieve high strength while comparing with normal concrete. At the same time while using tapioca powder by partially replacing cement, it will increase the setting time of concrete when compared to ordinary Portland cement. OPC has an initial & final setting time of 30 minutes and 10 hours respectively. But when partially replacing cement by tapioca powder it has an initial and final setting time of 90 minutes and 24 hours respectively.

Abstract: Every year, several onshore and offshore oil spills occur around the world, and these oil spills contaminate the soil. The physical and mechanical property of the ground gets altered as a result of contamination. Increasing petroleum exploration refining and other allied industrial activities have led to the wide scale contamination of soil. Amongst diesel and petrol, the consumption of diesel is higher. Therefore, diesel was selected as the pollutant and its effect on engineering properties of soil was studied. The present study focuses on evaluation of uncontaminated and contaminated soil with different concentration of diesel (8%,12%,16%,20% and at fully saturation by dry weight of the soil) were determined on samples of lateritic soil, sandy soil and clayey soil and the test results are compared to determine the effects of diesel contamination on some of the geotechnical properties. The testing included basic properties, Specific gravity, Atterberg limits, compaction, direct shear, and triaxial test and permeability tests. The results showed that the diesel contaminated soil samples have adverse effects on the geotechnical properties of the soil. The liquid limit, plastic limit and of the soil decreased as its diesel content increased. Strength and permeability of the soil decreased as its diesel content increased. If the foundation design for structures to be erected on hydrocarbon polluted soil does not consider the reduction in angle of internal friction and shear strength, this will ultimately affect the stability of shallow foundations, slopes, and other structures.

Abstract: Rapid industrialization is adversely impacting the environment globally. The study was carried out to evaluate the biophysical properties of samples contaminated by unplanned industrialization in terms of Effluent Treatment Plant (ETP) efficiency, availability and to evaluate the present scenario of water and air pollution by industrial discharges in order to create public awareness and its impact on public health. The study area was carried out in the second largest metropolis of Bangladesh, Chittagong. The study was carried out in 10 industries as a sampling station before and after treatment of industrial discharges and covered mainly two seasons, winter and dry seasons from November 2017 to June 2019.More than six parameters of effluents were analyzed. They are for total dissolved solids, total suspended solids, Total solids, dissolved oxygen, Chemical Oxygen Demand, Biochemical Oxygen Demand test etc. Collection, preservation and analysis of the samples were carried out in accordance with standard procedures. During analysis all precautions were taken in consideration.  The ranges of results of waste water obtained were 25 – 453 mgL-1 for total suspended solids (TSS), 2128 – 5,573mgL-1 for total dissolved solids (TDS), 2283- 5709mgL-1 for Total solids, 2.25 – 7.01mgL-1for dissolved oxygen, 27 – 403mgL 1for  Biochemical Oxygen Demand (BOD), 80 – 1436 mgL-1for Chemical Oxygen Demand (COD).Here almost all the parameters of industrial discharges are out of range prescribed by the Department of  Environment (DoE),Bangladesh which is so much frightening for us. So, the properly untreated industrial discharges mainly heavy metals are 

deposited in our bodies through food cycle and through inhalation particulate matters which impacts on our body. In this research work, around 100 workers and neighbors of those selected industries has been studied and found to face different health problems like skin problem, vomiting, convulsion, eye irritating problem, headache, loss of IQ, diarrhea, nausea, decrease in memory and other health problems etc.

Abstract: River sand, the most commonly used fine aggregate in concrete is very expensive now. Day by day, the cost of sand is increasing due to the scarcity and restrictions. Huge quantity of sand excavated from river bed destroys the stability of river banks. To avoid such situation and to meet the demand we have to think of an alternative or replacement material to sand. Crushed rock material, fly ash and sea sand are some of the alternatives. Different sizes of metal like 40 mm, 20mm and 10mm are obtained by crushing boulders of rock into small pieces in crushers. The residue of size less than 4.75 mm is called quarry dust which attracts various researchers as an alternative to river sand. This experimental work describes the study on the feasibility of the quarry dust for usage in concrete. To study the effect of quarry dust on the use of super plasticizer, sulphonated naphthalene based super plasticizer was added with fresh concrete of grades M20 and M25 using OPC and PPC separately. Super plasticizer was added at 1.2 lit/100 kg of cement as per the recommendation of the manufacturer. Water cement ratio was found out by conducting slump test for a constant slump of 60 mm. Tests were conducted in limited ratios of sand: quarry dust choosing one ratio each above and below the one giving maximum strength say 60:40, 50:50 and 40:60. At the age of 28 days the compressive strength, tensile strength and flexural strength were determined. From the test results it is found that the compressive strength, tensile strength and flexural strength are maximum at 50:50 ratios. These results on strength studies give a clear conclusion that quarry dust can be used as a good substitute for natural river sand with higher strength at 50% replacement compared with control concrete.

Abstract: The indiscriminate disposal of Effluent Treatment Plant (ETP) sludge from industries leads to soil, groundwater and surface water pollutions. To avoid the high costs associated with the disposal of large volume of this sludge, this material can be used in some building materials or can be used as fertilizer. As the accumulation of heavy metals in plants causes threat to living beings, it has to be pretreated to remove heavy metals from the sludge to required levels. Soil washing can be used to separate heavy metals from the sludge. For the present study, ETP sludge was assessed to know the removal efficiencies of five leaching solutions. The leaching solutions attempted were distilled water, 0.1 N HCl, 0.1 N EDTA, 0.1 N HCl + 0.1 N EDTA and 0.1 N FeCl_3. Column leach tests were conducted on the ETP sludge using the selected leaching solutions and the migration rates of different metal ions were determined. The efficiencies of different leaching solutions were compared and was found that 0.1 N HCl + 0.1 N EDTA and 0.1 N FeCl₃ are the most suitable solutions to remove heavy metals from this sludge.

Abstract:-Concrete is a manmade composite, the major constituent being natural aggregate such as gravel, or crushed rock, sand and fine particles of cement powder all mixed with water. The concrete as time goes on through a process of hydration of the cement paste, producing required strength to withstand the load. The cost of construction materials is increasing day by day because of high demand, scarcity of raw materials, and high price of energy. From the standpoint of energy saving and conservation of natural resources, the use of alternative constituents in construction materials is now a global concern. For this, the extensive research and development works towards exploring new ingredients are required for producing sustainable and environment friendly construction materials. The recycling of solid wastes in civil engineering applications has undergone considerable development over a very longtime. The utilization of fly ash, blast furnace slag, recycled aggregates, red mud, Kraft pulp production residue, waste tea, Quarry dust etc., in construction materials shows some examples of the success of research in this area. Similarly, the recycling of hazardous wastes for use in construction materials and the environmental impact of such practices has been studied for many years. Rapid increase in construction activities leads to acute shortage of conventional construction materials. It is conventional that sand is being used as fine aggregate in concrete. For the past two years, the escalation in cost of sand due to administrative restrictions in India, demands comparatively greater cost at around two to three times the cost for crusher waste even in places where river sand is available nearby. When examining the above qualities of fly ash and quarry dust it becomes apparent that if both are used together, the loss in early strength due to one may be alleviated by the gain in strength due to the other, and the loss of workability due to the one may be partially negated by the improvement in workability caused by the inclusion of the other.

Abstract: Black cotton soil is fertile and very good for agriculture, but it is not so good for civil engineering works. Major source of power generation in India is the thermal power plants producing more than 150 million tons of fly ash annually as a by-product, due to combustion of the pulverized coal posing not only disposal problems but also serious health and environmental problems. To control these problems, the most commonly used method is addition of fly ash as a stabilizing agent usually used in combination with soil. In this study, fly ashes were used to investigate the effect of fly ash on the various potential of BC soil. Based on the favorable results, it was concluded that the fly ash could be successfully use as an effective additive in stabilization of problematic soils.

Abstract: A laminated composite beam consists of more than one lamina bonded together through their thickness. Laminate layers are stacked at different angles to withstand different loading and stiffness requirements. This paper deals with the analysis of laminated composite beam using FEMAP Nx Nastran and the results for transverse displacement are obtained. The results from FEMAP software are validated with standard research paper of Khdeir and Reddy [1]. The beam size used for the analysis is of 0.1m x 0.1m in crosssection and 1m in length. Both symmetric [0/90/0] and antisymmetric [0/90] layered beams are analysed and validated. Parametric study is also done on the symmetric laminated composite beam [0/90/0] by varying the L/h ratio, boundary conditions, and E1/E2 ratios and the results are tabulated and conclusions are made.

Abstract: A 5th order shear deformation theory considering transverse shear deformation effect is presented for static flexure analysis of fixed isotropic beam. The assumed displacement field accounts for non-linear variation of inplane displacements as well as transverse displacement through the beam thickness. The condition of zero transverse shear stresses on the top and bottom surface of beam is satisfied. Hence the present formulation does not require the shear correction factor generally associated with the first order shear deformable theory. Governing equations and boundary conditions of the theory are obtained using the principle of virtual work. Closed form analytical solutions for fixed isotropic thick beams subjected to various loads are obtained. Numerical results for static flexure analysis include the effects of side to thickness ratio and beam aspect ratio for fixed isotropic beams. The results of present theory are in close agreement with those of higher order shear deformation theories.

Abstract: Trip rate is the ratio of the Total several trips generated per day to the Total population of the considered area. While considering a city as a study area it is difficult to relate the amount of trips that originate in that study area and the amount of trips attracted towards the study area in a conventional way. This study brings out some basic Demand variables that helps in estimating the several trips in a study area. Relationship between Dependent (trip rate) and Independent (socio-economic &Land use) variables is established using Artificial Neural Network (ANN) using different learning functions which reflects its performance level. In this study we have used learning functions TRAINLM, TRAINSCG which provided better results in establishing the relation between Trip rate and Demand variables.

Abstract: Earth is facing major environment related problems today such as Global warming and loss of bio-diversity. This brings in the need for Sustainable development, which meets the needs of the present without compromising the ability of future generations to meet theirs. Use of recycled materials in construction, such as recycled aggregates, fly ash, silica fume etc. leads us to less energy consumption in terms of production of cement, transportation etc., less quarrying and thus protection of bio diversity at both quarrying site and dumping sites. But properties of recycled material such as recycled aggregate are substantially different from that of natural aggregates hence prediction of performance of RAC becomes difficult. Here, an attempt is made to predict performance of RAC concrete using modern soft computing tool, i.e. Artificial Neural Network. 136 sets of experimental data from various literature sources were used to train and test the ANN model. The developed ANN model used 14 input parameters and compressive strength at 28 days as output parameter. The results showed that ANN has good potential to be used as a tool to predict strength of sustainable RAC concrete prepared with varying types, sources and ages of recycled aggregate and using industrial wastes.

Abstract: Due to the fresh land unavailability for the construction of infrastructure in present time, there are several techniques for the land reclamations. The main idea is to get a higher density of soil at site which finally gives the higher value of the shear strength and bearing capacity. The density can be increase by many techniques. Some of them required removal the water where the soil have a higher amount of the water content because high amount of water in the voids leads to lower shear strength and load carrying capacity. Creating the load bearing column which can drain water form low permeable soil and bear the load of superstructure on the weak soil (stone column,).And there are some other methods which glue the soil solids together and enhance its specific properties using geo materials (grouting, soil nailing).

Abstract: This paper presents experimental study on the properties of self-compacting concrete (SCC) amended with two additional cementitious materials (fly ash and slag) on the mechanical performance of self-compacting concrete (SCC). Portland cement (PC) was replaced with fly ash (FA), Ground Granulated Blast Furnace Slag (GGBFS). The effect of these admixtures on the fresh and hardened SCC of various mix proportions was studied. It was observed that there was a very small difference in workability and strength of SCC when the cement was partially (30%) replaced by GGBFS and fly ash at various proportions. From the results obtained, it is concluded that GGBFS replacement in concrete considerably increases the strength of concrete.
