Experimental Study On Replacement Of Aggregate With Scrap Rubber Tyre In Cement Concrete

The increasing demand for sustainable construction materials and the growing environmental problems associated with waste tyre disposal have encouraged researchers to explore alternative materials in concrete production. This study presents an experimental investigation on the replacement of natural coarse aggregate with scrap rubber tyre particles in cement concrete. The primary objective is to evaluate the feasibility of utilizing waste rubber as a partial aggregate replacement while maintaining acceptable mechanical performance and promoting eco-friendly construction practices.Concrete mixes were prepared by replacing coarse aggregates with scrap rubber tyre particles at different percentages of 0%, 5%, 10%, and 15% by weight. The mix design was carried out in accordance with IS 10262 guidelines, and specimens were cast and cured under controlled laboratory conditions. Fresh concrete properties were evaluated using the slump test, while hardened concrete properties were assessed through compressive strength and split tensile strength tests at 7 and 28 days of curing.
