    Effect of Fineness of Sand on the Cost and Properties

    2020-7-18The 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 CostBenefit 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.
