Manufactured Sand for Construction - Structural Guide

2021-8-30  Manufactured sand can be considered as a by-product of the process of producing coarse aggregates. When the rock is crushed into small particles, fine aggregates are produced. Due to the increasing demand in the construction sector, there is a difficulty in supplying the rever sand continuously to meet the demand.

Use of Manufactured Sand in Concrete and Construction

2021-8-20  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.
