Abstract: Disposal of tyre rubber suit a gigantic dilemma in India day by day. Researchers are trying to use waste rubber in civil engineering project from many days back. Crumb rubber replaced fine aggregate is a common practice now a days. Researcher already replaced upto 20% chipped rubber with coarse aggregate earlier and found that 5% replacement is optimum but that lack some strength from conventional concrete. In this research programme researcher have tried to minimise that gap by adding extra 5% micro silica of the weight of cement and have also replaced 40% cement by GGBS. To check the durability against acid and salt, cubes, cylinders and prisms are casted to test compressive strength, tensile strength, flexural strength after immersing in 5% by volume of sulphuric acid and 5% by weight of sodium chloride salt. Water absorption test, mass loss/gain test are also observed after 56 days.
