Performance evaluation of mechanical behaviour of concrete with recycled aggregate and M-sand

Abstract

The research proposes to replace M-sand with construction and demolition waste (C&D) as a fine aggregate (FA). Because sand is in high demand these days, results in the whole cost of building rise. This research area focuses on the efficient use of building and demolition waste as Recycled Fine Aggregate (RFA), as well as environmental considerations. In concrete, recycled fine aggregate (RFA) was used as FA. The concrete was made with its qualities and compared to 100% M-sand. The outcome of the production of standard cement mortar with M-sand and recycled aggregate replacements of 25 percent, 50 percent, 75 percent, and 100 properties among the numerous trails on 7 days and 28 days. The test results show compressive strength of 13.08 N/mm2 at 7 days and 17.149 N/mm2 at 28 days, split tensile strength of 1.284 at 7 days and 1.734 at 28 days, and flexural strength test of 5.689 at 7 days and 6.47 at 28 days. As a final ending this RFA is a useful material in modern building.
