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.

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

You are correct @Rahul Chaurasia.

Standard W/C ratio, 0.45 * 50 = 22.5.

According to me, the answer is 20lts.

w/c ratio =.4
Then weight of water .45x50=22.5.
Then weight of water .45x50=22.5.

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.
