Abstract

Due to a surge in construction activities and infrastructure developments, concrete is the most in-demand material. Because there is less natural sand available, building projects are becoming more expensive. An effort has been made in the current endeavour to provide a substitute for natural sand. Abrasion, impact, and water absorption resistance of M40 and M50 grades of concrete have been studied with manufactured sand as fine aggregate and the results have been compared with conventional sand concrete. Durability studies, such as water absorption, rapid chloride permeability test, sorptivity, acid resistance, alkaline resistance, impact resistance, and abrasion resistance, have also been studied. According to the findings, using synthetic sand in place of sand as fine aggregate increases durability attributes by up to 70%, and using it exclusively results in concrete with superior durability than traditional sand concrete.
