STUDY ON USING GRINDING PRODUCTS FROM WASTE RUBBER TO REPLACE A PART OF THE AGGREGATE IN CEMENT CONCRETE PRODUCTION

Abstract

The article presents research results using crushed products from waste rubber to replace a small aggregate and large aggregate part in the manufacture of cement concrete. First, rubber mixtures are classified according to the particle size group corresponding to the size of aggregate to be replaced. Then, small aggregate and large aggregate, at the same time, are replaced by rubber particles with different proportions. The research results show that it is completely possible to fabricate cement concrete grade M20 - M30 when replacing 10-25% of the aggregate volume with a rubber mixture having the same particle size. This has great significance in the search for alternative raw materials to make concrete, in order to reduce the exploitation of natural resources, contribute to limiting environmental pollution, and towards the goal of sustainable development.
