As a construction material, concrete is the largest production of all other materials. 

Aggregates are the  important constituents in concrete .The increase in demand for the ingredients of concrete is met by partial replacement of materials by the waste materials which is obtained by means of various industries. Steel slag is a waste product generated during the production of steel and world wide production of tyre increases due to increase of automobile industry. The huge amount of waste tyre needs to be dispose. These wastes are disposed in the form of landfills causes an enormous amount of land pollution. So for the increasing demand to protect the normal environment, especially in build up areas, the needs to use these wastes are very important. Therefore, replacing some portion of natural aggregates with steel slag and  scrap rubber waste would lead to considerable environmental benefits. The present work is to use  steel slag and rubber waste as replacement for fine aggregate.
