USE OF M-SAND IN CONCRETE AND MORTAR AS AN ALTERNATIVE OF RIVER SAND

Civil Engineering

M SAND (4.75 mm sieved stone powder) produced from stone crushing zones appears as a problem for effective disposal. Sand is a common fine aggregate used in construction work as a fine aggregate. In this study the main concerns to find an alternative of sand. Substitution of normal sand by M sand will serve both solid waste minimization and waste recovery. The study focuses to determine the relative performance of concrete by using powder sand. From laboratory experiments, it was revealed that concrete made of M sand gained about 15% higher strength than that of the concrete made of normal sand. Concrete of M sand gained about 10% higher strength than that of the concrete normal sand and stone chip concrete. The highest compressive strength of mortar found from M sand which is 33.02 Mpa, shows that better mortar can be prepared by the M sand. The compressive strength of concrete from M sand shows 14.76% higher value than that of the concrete made of normal sand.
