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.

manufactured by the authorized 10 M-sand quarries. To cope up with the crisis, developers are now finding other alternatives. M-sand is an alternative solution for demand of river sand and in future most of the construction project will be fully dependent on M-sand. Hence it is important to study its properties and its behavior in concrete.

The manufactured sand has required gradation of fines, physical properties such as shape, smooth surface textures and consistency which makes it the best sand suitable for construction. These physical properties of sand provides greater strength to the concrete by reducing segregation, bleeding, honeycombing, voids and capillary.

M sand differs significantly in physical and mineralogical properties, as compared to river sand. Here are the main properties of manufactured sand: The shape of this artificial sand is cube-like or angular. It has a rough texture. Thus, it is preferred for making concrete.

The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical.
