Compressive strength of concrete made with M-sand is marginally higher (6%-9%) when compared to that of river sand. Hence, I conclude that M-sand concrete possesses higher compressive strength when compared with river sand concrete. The results pertained to that M-sand can be 100% replaced and possess greater characteristic strength.
