Effect of Fineness of Sand on the Cost and Properties of

In this study water-cement ratio (W/C) of mix is kept constant for all the trial mixes with sand of different fineness modulus. Workability of mix is also fixed in range of 45 to 55 mm slump. Since mix with so different fineness modulus of sand, will result in different water demands, so watercement ratio is kept constant and to adjust
