For thin structures subjected to wetting and drying, the water-cement ratio should be 0.45.
For mass concrete structures subjected to wetting and drying, the water ratio should be 0.55.
For thin structures which remain continuously underwater, the water-cement ratio by weight should be 0.55.
For massive concrete structures which remain continuously underwater, the water-cement ratio by weight should be 0.65.

Water for complete hydration req =23%by wt.
But for interapted voids 15%more water will be req so 15+23=38%,
Becouse we dont have any w/c ratio so for one bag water req will be =0.38*50=19litter.
So no ans match but nearby 20.5 is correct.

if the water-cement ratio is specified as 0.45, the quantity of mixing water required per 50-kg bag of cement is 0.45 - 50 = 22.5 lt or kg.

But the min w/c ratio is 0.4 and max w/c is 0.8 how we can consider 0.45?
They must have to specify the w/c ratio. Please explain.

Minimum water cement ratio for workable concrete is 04.
So, we may say 0.4*50 = 20 liters. I think the answer should be 20.5.

For 50 kg bag 35L of water is required. Without w/c ratio one can't find the solution.
Am I right? Please explain me.

Min water required for complete hydration of cement is 42% by wt of cement
So, water req is 42*50 = 21.
So, water req is 42*50 = 21.

For normal consistency, minimum w/c ratio is 0.45 that's why w = 0.45 * 50 = 22.5.

Here W/C ratio is not given then how it is calculated, can anyone explain it?

34.5 m3 volume in a bag of cement.
So, approx 17-19 litre of water.
