Abstract:-The main aim of this study is to observe the behavior of E-coli bacteria on durability properties of concrete, also know the effect of replacement of natural sand by M-Sand(40% replacement), with different cell concentration( 0,105,107 cells/ml) of E-coli bacteria were used for concrete mixes. The test was carried out on the durability properties after complete curing of 28 days. The test results shows inclusion of E-coli bacteria in concrete has an ability to enhance durability by reducing water absorption and sorptivity of concrete and also have great resistance ability to sulphate.
