It is pointed out that manufactured sand is anytime better than river sand. The particle shape is cubical, which is almost closer to rounded river sand. Another issue associated with river sand is that of obtaining required grading with a fineness modulus (FM) of 2.4 to 3.1. Generally FM of 2.2 to 2.6, 2.6 to
