Kota stone Dust, crumbed rubber, concrete etc.

Concrete is the basic material of any infrastructure project, without concrete development in construction industry will be difficult.. Concrete consists of Cement, fine aggregates, Gravels, Water, Admixtures. In this research work partial replacement of sand is done by Kota stone Dust and crumbed rubber in different percentages (0%, 5%, 10%, 15% & 20%) in concrete.

Kota stone dust is waste product obtained by Kota stone quarries while placingkota stone. A large amount of waste  is produced by such quarries only small quantity is used and rest is dumped . This can be used as replacement of fine aggregate.

Crumb rubber is recycled rubber produced from automotive and truck scrap tires. Rubber pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, or humansFor this dissertation concrete of grade M 25 & M 30 in a design mix proportion was formed and then tested for compressive , spilt tensile and flexure strength.
