Estimation of compressive strength of concrete with manufactured sand
MS is made by mechanical crushing and screening of rock particles. The process results in sharp-shaped particles with rough surfaces and generates a certain amount of stone powder [14], [15].The rough surface of MS increases the number of contact points and enhances the overall surface area among particles, contributing to a denser particle arrangement.
