ABSTRACT
For the last decades concrete producers have made wide use of waste or by-product materials in concrete [1]. Proper replacement of these materials in concrete would have two major significant: improving fresh and hardened properties of concrete and minimizing the environmental pollutions due to solid waste disposal. Rubber is one of the materials which are not biodegradable. For solving the disposal of large amount of waste rubber, reuse in concrete industry may be the most feasible application [2].
