Answer / santosh singh

According to British Standard Specifications

water requirement of concrete = 28% by weight of cement + 4% by total weight of aggregate

M25 M20 M15
proportion 1:1:2 1:11/2:3 1:2:4

water cement ratio 0.43 0.51 0.58
(by weight)

quantity of water is calculated as

for M20
wt of water/wt of cement(50kg) = 0.51

Wt of water per bag of cement = 0.51 x 50 = 25.5 liters

similarly for M25

wt of water per bag of cement = 0.43 x 50 = 21.5 liters

wt of water per bag of cement = 0.58 x 50 = 29 litres
