5. Pit Sand It serves as an excellent material for mortar or concrete work. Pit sand must be made free from clay and other organic materials before it can be used in mortar. A coating of oxide of iron over the sand grains should be removed. 6. RIVER SAND This sand is widely used for all purposes.

A further advantage is that less maintenance is required for a given level of use when compared to natural grass. However it is a myth that artificial playing surfaces are maintenance-free. For example, an artificial grass pitch is likely to have the same annual maintenance cost as a turf pitch, but be able to take ten times as much use 3.

Before we get into the advantages and disadvantages of manufactured sand, what exactly is manufactured sand? Manufactured sand is sand produced by crushing rocks, quarry stones or larger aggregates pieces into sand-sized particles. Natural sand, on the other hand is the naturally formed sand extracted from river beds.

Aerated concrete does not contain coarse aggregate, and can be regarded as an aerated mortar. Typically, aerated concrete is made by introducing air or other gas into a cement slurry and fine sand. In commercial practice, the sand is replaced by pulverized-fuel ash or other siliceous material, and lime maybe used instead of cement [2].

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.
