STUDY OF MECHANICAL PROPERTIES ON M25 GRADE OF CONCRETE BY REPLACING OF DEMOLISHED CONCRETE WASTE INSTEAD OF COARSE AGGREGATE

Abstract

The hardened Concrete waste can be reused in concrete for achieving the economical construction. In this paper, describes the reuse of demolished concrete in concrete instead of coarse aggregate. Such reusing not only helps conserve natural resources, but also helps to reduce the cost of construction. The demolished concrete was used to replace upto 10% of coarse aggregate. The tests were carried out in laboratory to evaluate the strength properties of normal concrete by using this demolished concrete as coarse aggregate. These tests included workability, unit weight, compressive strength, flexural strength and split tensile strength. Test results give significant strength improvement in concrete.
