Wt of water = (5% wt of coarse aggregate+30% wt of cement)*w/c ratio.

Please read question, it's giving 50kg of FINE aggregates not cement.

.3p+.1F+.01C= w/c xp

By using this equation, we can get the answer.

If the mix is 1:3:6, Can we use same method keeping same wc ratio?

ConcreteSukan said:   9 years ago
(5% Coarse aggregate + 30% of cement (50kg here))* w/c is correct.

Water cement ratio are different for different grade of concrete.

Is this (equation) useful for all concrete mix? Please explain.

C = 1/7 * 150 = 21 (1;2;4) = 7,
W/C = 0.6,
W = 0.6 * 21 = 12.

@Sumit, 50 kg is the weight of fine aggregates, not cement.
