Use of Manufactured Sand in Concrete and Construction An Alternate to
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.

Properties of Concrete
The United States, unless otherwise specified, compression tests of mortar are made on 50-mm (2-in.) cubes, while compression tests of concrete are made on cylinders 150 mm (6 in.) in diameter and 300 mm (12 in.) high or smaller cylinders sized at 100 mm x 200 mm (4 in. x 8 in.). Most general-use concrete has a compressive strength between 20 MPa and 40 MPa (3000 psi and 6000 psi).
