Of course, 30kg is correct. I also agree.

You are right @Nitu Bharti. Thanks.

Here the question is "the quantity of water required per bag and W/C ratio is 0.6" then the water required for 1 bag of cement is 30 Kg.

Asif wazir said:   7 years ago
30 kg is correct because for 14 kg the WC ratio becomes 27 which is less than even the hydration water required for a single bag of cement.

36 liter is the correct answer as per empirical formulas.

NIKUNJ said:   1 decade ago
Water required per bag means:

Cement bag = 50 kg.

W/c ratio = 0.6.

Water = 50 x 0.6.

Hence water = 30 kg.

If we assume water absorption in calculation then water require more than 30 kg.

Its wrong answer is 30 kg.

How can we take water for aggregate if nothing is mentioned?

S. kumar said:   1 decade ago
3 times of cement is fine sand, aggregate is 6 times actually. How you can take aggregate 3 times? Explain please?

37 kg right answer.

5/100*9*(50)+30/100*1*(50).
22.5+15= 37.5 litre water required.

5 mean 5 per cent of aggregate+ 30 per cent of cement= wt of cement.
9 = 6+3 = aggregate ratio.
1= cement ratio.

Why we take aggregate 150 kg?

3 times of cement? Explain please?
