Problem statement: Nowadays, the use of waste tyre in concrete has become technically feasible and the tyre mixed concrete is light weight and called as rubberized concrete. Still the research is going on to explore basic engineering properties such as transport properties viz, acid absorption test, water absorption tests, impact resistance, modulus of elasticity, dynamic modulus and so on. In this study, the studies are limited to acid absorption test, water absorption test and energy absorbed by impact. Approach: Experimental investigations were conducted on tyre fiber specimens with different variables such as length, diameter of holes and percentage of coarse aggregate replacement by tyre fibers. Impact resistance test was done by ACI standard and acid and water absorptions tests were conducted by Indian standard. Results: In this study, experimental results based on the water absorption, acid resistance and impact resistance of the rubberized concrete were analyzed. These experiments were conducted on rubberized concrete with tyre fibers mixed in different sizes and proportions by weight with the coarse aggregate. The specimens were immersed in water and in diluted HCL (5% concentration) acid for 28 days and tested. Conclusion: The results obtained from the tests are use to determine the optimum size of the tyre fiber specimen that could be used in the rubberized concrete mixture to give the optimum performance. The rubberized concrete with tyre fiber specimen L50-D5 10% has shown good transport characteristics and impact resistance.
