Durability of Concrete: Manufactured sand has lesser impurities when compared with the river sand. There is no silt or clay in the M-Sand. Further, its chemical composition is also balanced as they are taken from the good rock. Concrete made with M-sand can withstand severe environmental conditions. Further, it reduces the corrosion of reinforcement and permeability. In general, it has good

In concrete pavement, it was found by the CCAA (2012) that the free silica limit used in the selection of natural sand to provide good skid and abrasion resistance to concrete pavement does not necessarily apply to manufactured sands.

Manufactured sand provides an opportunity to control the particles'' mineral content, in contrast to natural sand, which often contains undesirable minerals and clays whose effects on concrete quality can be very harmful. Another reason for using manufactured sand is the growing shortage of natural sand. The best fine material for concrete production is cubical sand made from crushed rock. The
