Manufacturing of Sand process involves three stages, crushing of stones in to aggregates by VSI, then fed to Rotopactor to crush aggregates into sand to required grain sizes (as fines). Screening is done to eliminate dust particles and Washing of sand eliminates very fine particles present within. The end product will satisfy all the requirements of IS:383 and can be used in Concrete

Effect of Fineness of Sand on the Cost and Properties of . 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.

From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which may cause cracking. In this study, we have used grit and crushed sand for the design mix and found the characteristic compressive strength at 3,7 and 28 days respectively.
