Abstract

A large amount of rubbers are produced in the world, and the disposal of these waste materials is not feasible, as the rate of decomposition for tyre is very slow.  These waste material produce big environmental pollution, therefore optimum use of them has become a necessity. These kinds of trashes can be used for improving some mechanical properties of concrete. In this regard compressive strength of concrete specimens containing crumb rubber, rubber powder, along with nanosilica have been discussed at the ages of 7 and 28 days in the current research. A fixed water – cement ratio has been considered in the mixes. Crumb rubber particles ranging in size from 4.75 to 9.50 mm, and rubber powder of size 0.6 mm have been used.  In this paper 5%, 10%, 15% (by weight of cement) of rubber have been used, and also 2% and 3% nanosilica were added to the mixes containing rubber.  The results showed an improvement in the failure behavior, and compressive strength growth of concrete containing rubber and nanosilica.
