Calculation of Fineness Modulus of Sand. Let us say the dry weight of sample = 1000gm After sieve analysis the values appeared are tabulated below. Therefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = 2.75 Fineness modulus of fine aggregate is 2.75. It means the average value of aggregate is in between the 2 nd
