    Dear Sir First of all you need to know the quantity of cement. 1:2:4 Means M15 Grade Cement require for 01 Cu.m Concrete is: Wet volume of concrete is 1.54 Cu.m = (1.54/1+2+4)*1 = 0.22 Cu.m Now 0.22 Cu.m Cement = 0.22*1440 Kg/m3 (Density of cement) =316.80 kg cement = 316.80 kg   Now W/c NormalRead more

    Dear Sir

    First of all you need to know the quantity of cement.

    1:2:4 Means M15 Grade

    Cement require for 01 Cu.m Concrete is:

    Wet volume of concrete is 1.54 Cu.m = (1.54/1+2+4)*1 = 0.22 Cu.m

    Now 0.22 Cu.m Cement = 0.22*1440 Kg/m3 (Density of cement) =316.80 kg cement = 316.80 kg

     

    Now W/c Normally require for M15  Grade is 0.50

    So water require: W/C = 0.50 =

    C*0.50 = Water

    316.80*0.50=Water

    Water = 158.40 Litre/Cu.m
