Answer / pankaj
not such that but we can consider it as 0.48 for nominal mix it is totally depends on concrete ex poser condition and grade of conc. and cement consumption also consider

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
