The fineness modulus of sand used in ordinary concrete is 3.7-1.6, medium sand is suitable, and coarse sand plus a small amount of fine sand can also be used, and the ratio is 4 to 1. For natural sand, one fineness modulus can have multiple gradations. For artificial sand, one fineness modulus corresponds to only one gradation.

Unlike sand from rivers, artificial sand is manufactured by breaking down the large aggregates of rocks and mines into smaller portions with a defined size of 4.75mm. It is majorly implied in the construction industry. Furthermore, the other major components used in the production of artificial sand include fly ash concrete.

natural sand by artificial sand. They concluded from experimental results that, mixes with artificial sand as a fine aggregate gives better strengths than mixes of natural sand due to sharp ages of the particle in artificial and provide better bond with cement than rounded particle of natural sand.

Natural (River) Sand. Natural sand has an excellent modulus of 2.78 and, after washing in clean water, complies with Zone II according to IS: 383-1970. The specific gravity of this natural sand was found to be 2.55. The water absorption and moisture values obtained for the sand used were 6% and 1.0%, respectively. 3.

A mix proportion for M25 grade concrete is derived with standards confirming to IS codes. RCA was partially replaced for coarse aggregate in the proportions of 20%, 40% and 60% fine aggregate by M-sand for . The fresh and hardened properties of thus prepared concrete are studied and compared with concrete made using conventional materials.
