Due to the huge increase in the population and number of vehicles, lots of tyres are ending as waste every
day. It was estimated that every year almost 1000 million tyres end their useful life and more than 50% are
discarded without any treatment. One of the possible solutions for the effective use of waste tyre rubber is
to incorporate into cement based materials, to replace some of the natural aggregates. In this study, waste
tyre rubber in the form of crumb rubber was used as a partial replacement for natural fine aggregates in
high strength cement concrete. Crumb rubber was replaced for fine aggregates from 0% to 20% in multiples
of 2.5%. Tests were done to determine the depth of carbonation, water absorption of acid attacked
specimens, compressive strength of acid attacked specimen, variation in weight of acid attacked specimen
and chloride penetration of these concrete samples. From the test results it could be concluded that the
high strength rubberized concrete are highly resistant to the aggressive environments.
