"EXPERIMENTAL STUDY ON WASTE RUBBER AS APARTIALREPLACEMENT OF COARSE AGGREGATES IN CONCRETE"

Abstract

Dumping of waste rubber tires has become major issue in India in the past few years as it has very fewuses, and if new tires are to be produced from waste rubber then it has to be melted and remolded. This process internincreases pollution and releases toxic gases in the air, which are harmful to the environment as well as livingcreatures. The main constituent of glass is silica; hence it can be helpful in AAR which take place in all types of concrete. Natural coarse aggregate are extracted from quarries and a result this quarries will soon be depletedinfew decade if the rate of their uses continuous at this pace .As a result there was a need of permanent solutionto this long-lasting problem. Keeping this view the feasibility of use of waste tires as replacement of coarseaggregate construction has been experimentally assessed in this project. Basic mechanical and physical test have been carried out on aggregates. The strength and durability characteristics of concrete mixtures have beencomputed in the present work by replacing 0%, 5%, 10%, 15% and 20% of coarse aggregates with the wastetyre rubber.
