EXPERIMENTAL INVESTIGATION ON HIGH STRENGTH CONCRETE USING PARTIAL REPLACEMENT OF RECYCLING COARSE AGGREGATE

Abstract

The primary material used in construction is concrete. Cement, fine aggregates, coarse aggregates, and water make up concrete. However, the quick exhaustion of those resources and, consequently, their rising cost are becoming attention-seeking issues. As a result, the construction industries are facing difficulties related to the simple availability of those resources. This is why a number of solutions, such as the recycling and reuse of building waste, are being used to address the issue. In this area, our initiative seeks to use concrete that has been removed. In this project, we used M40 grade concrete to replace coarse aggregates with destroyed concrete in the following ranges: 0%, 20%, 30%, 50%, The prepared concrete mix is evaluated and compared to standard concrete in terms of workability tests, compressive strength, etc. The test will be run at 7, 14, and 28 days in order to evaluate the strength characteristics.
