A huge amount of concrete is consumed in construction works. About 35 % volume of concrete is comprised of sand. Generally, cement and coarse aggregates are factory made products and their quality and standards can be easily controlled and maintained. The sand is usually excavated from river beds or river bank by digging.
As with standard Portland cement concrete, it is best to build forms to contain the soil-cement surface. If building permanent forms, use pressure-treated dimension lumber (2 x 4s are generally best) nailed together and staked in place. Use a level to make sure the forms have a slight pitch to allow for water to drain off.
Cement stabilized sand is widely available and cost-efficient; it utilizes less cement for a surface area while maintaining its durability. At Southern Crushed Concrete, our cement stabilized sand contains only lightweight pieces and is free of any organic damaging substance, as required by the City of Houston and Harris County.
Density of construction materials are its mass per unit volume of materials. It is expressed in kg/m3 or lb/ft3 and shows compactness of building material. Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material.

The net cost of Concrete reduces when FM of sand increases. It reduces by about 6.5% for an increase of FM from 2.0 to 3.0. As the fineness modulus of Sand increases, the Cost/Benefit Ratio reduce by a very large factor. This is 29% when FM changes from 2.0 to 3.0. That means we can get large advantage by using concrete having Coarse Sand.
