Use of Manufactured Sand in Concrete and Construction An

The Civil engineers, Architects, Builders, and Contractors agree that the river sand, which is available today, is deficient in many respect. It does content very high silt fine particles (as in case of Filter sand). Presence of other impurities such as coal, bones, shells, mica and silt etc makes it inferior for the use in cement concrete.
