Calculate Quantities of Materials for Concrete Cement
#0183;#32;Cement = Sand = Coarse aggregates = The percentage of entrained air assumed is 2%. The mix proportion of 1::3 by dry volume of materials can be expressed in terms of masses as: Cement = 1 x 1500 = 1500. Sand = x 1700 = 2550. Coarse aggregate = 3 x 1650 = 4950.
