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.

Oct 02, 2015 Regarding correct grade of sand I just set up my misting bed and needed a half ton of coarse sand. After visiting a few different sources for sand and enduring amused grins regarding terminology I discovered that in central CT the correct grade is referred to as concrete sand. It is often used to provide the bed for patio blocks.

The results show that the manufactured sand concrete made in this study generally requires a higher watercement wc ratio for workability equal to that of natural sand concrete due to the higher angularity of the manufactured sand particles. Water reducing admixtures can be used to compensate for this if the manufactured sand does not
