Vol 9, No 3 (2024): Pervious Concrete Pavements

Authors: Ms. K. Chaitra, Gundamaina Harisai

Abstract: Pervious concrete pavements have emerged as a sustainable solution to address challenges posed by urbanization and storm water runoff in built environments. Unlike traditional impermeable pavements, pervious concrete is designed with interconnected voids that allow water to infiltrate through the surface, promoting groundwater recharge and reducing the burden on conventional drainage systems. This abstract explores the fundamental characteristics, benefits, applications, and challenges associated with pervious concrete pavements. It begins by elucidating the composition of pervious concrete, which typically includes coarse aggregates, cementations’ materials, and water, formulated to achieve high porosity and permeability. The resulting open-cell structure enables rapid drainage of rainfall and minimizes surface runoff, thereby mitigating flooding risks and controlling erosion. The environmental benefits of pervious concrete extend beyond storm water management. By filtering pollutants and contaminants as water percolates through the pavement, it improves water quality in adjacent ecosystems and reduces the discharge of harmful substances into water bodies. Additionally, pervious concrete contributes to urban heat island mitigation by enhancing evaporative cooling and supporting vegetation growth within urban landscapes. Applications of pervious concrete pavements encompass various settings, including parking lots, sidewalks, driveways, and low-traffic roadways, where its ability to handle pedestrian and vehicular traffic while managing storm water effectively is advantageous. Case studies of successful installations highlight its versatility and performance under diverse environmental conditions. However, challenges such as potential clogging of voids due to sediment accumulation necessitate careful consideration of maintenance practices, including regular vacuuming and cleaning to sustain optimal permeability over time. Furthermore, proper installation techniques, such as adequate compaction and curing procedures, are critical to achieving desired durability and performance outcomes.

Authors: Vadla Dinesh

Abstract: Improving concrete durability is essential for creating long-lasting structures. This involves using supplementary materials like fly ash, silica fume, and GGBS to enhance strength and reduce permeability. Admixtures, such as water-reducers and air-entrainers, further increase resistance to environmental damage. Surface treatments, like silane coatings, protect against water and chloride ingress. Additionally, fiber reinforcement, proper curing techniques, and the use of high-quality aggregates contribute to the overall resilience of concrete. Advanced methods, including the integration of nano-materials and corrosion inhibitors, also play a key role. Together, these strategies lead to more durable, low-maintenance, and sustainable concrete structures.

Vol 9, No 2 (2024): Fire Resistance Evaluation of Recycled Aggregate Concrete: Experimental Study and Analysis

Authors: Chaitra K

Abstract:  To assess the fire resistance performance of recycled aggregate concrete (RAC) components with varying compressive strengths, four full-scale concrete columns were designed and tested under high-temperature conditions. Two of the specimens were constructed using normal concrete with compressive strengths of C20 and C30, while the other two were made from recycled coarse aggregate (RCA) concrete with compressive strengths of C30 and C40. These specimens were subjected to identical constant axial forces and exposed to simulated building fire conditions in a laboratory furnace. Various parameters from the experimental results were analyzed and compared, including temperature change, vertical displacement, lateral deflection, fire endurance, and failure characteristics. The temperature distribution within the specimens was simulated using ABAQUS Software (ABAQUS Inc., Providence, RI, USA), and the simulated results closely matched the experimental findings. The results indicate that the rate of heat transfer from the surface to the interior of the columns increases with higher concrete compressive strengths for both RAC and normal concrete columns. Under identical initial axial force ratios and column cross-sections, columns with lower concrete compressive strengths exhibited better fire resistance performance. Additionally, the RAC columns demonstrated superior fire resistance performance compared to the normal concrete columns with equivalent compressive strengths.

Vol 9, No 1 (2024): Utilizing Tetrapak Recyclables in Sustainable Building Practices

Authors: Deeksha Singh, Neha Rawat

Abstract: In contemporary Civil Engineering, a pressing challenge lies in developing construction materials that meet the dual criteria of sustainability and durability. The accumulation of solid waste stands as a significant threat to the global environment. Among these waste streams, Tetra Pak cartons, commonly employed in food packaging, contribute substantially. Comprised mainly of paper, with paperboard constituting 75% of its composition, polyethylene 20%, and aluminum 5%, Tetra Paks pose a recycling challenge. Recent research by TERI on used beverage carton (UCB) management revealed a recycling rate of 54% in India in 2019, with active recycling at 31% and inactive recycling at 23%. In response, efforts were made to explore innovative uses for Tetra Pak waste in construction material development. This involved crafting boards without conventional resin binders, relying instead on the adhesive properties of melted aluminum foil and polyethylene inherent in Tetra Paks. These boards show promise for construction panel applications, with tests conducted on compressive and flexural strength, swelling index, flame resistance, and other parameters comparing favorably to standard boards. These findings suggest the potential for integrating this material into lightweight construction practices.

Authors:P. Guruswamy Goud, S.Priyanka, J.Anvesh, K.Prabhakar

Abstract: Concrete consumption has risen as a result of rapid global infrastructure development and increased material science, among other causes. Cement, an essential component of concrete, bonds the various solid components together to produce a cohesive mass. Cement manufacture produces a significant amount of greenhouse gases, accounting for about 10% of global carbon (IV) oxide (CO2) emissions. This, combined with a rise in environmental activism, has resulted in the creation of a number of novel solutions & supplementary cementitious materials. Palm oil fuel ash (POFFA) is a unique industrial byproduct that results from the burning of palm oil wastes in power plants for electricity generation. It is a highly reactive substance with strong pozzolanic tendencies and adequate micro-filling capacities. A review of concrete strength as influenced by the use of POFFA as a partial replacement for cement in concrete is offered in this research. The compressive strength of concrete as effected by the % replacement & fineness of POFFA in concrete is mainly explored here, based on data published in the literature on the utilization of POFFA in blended concrete. The benefits & drawbacks of POFFA in concrete are also discussed.
