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.

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.
For mass concrete structures subjected to wetting and drying, the water ratio should be 0.55.

For massive concrete structures which remain continuously underwater, the water-cement ratio by weight should be 0.65.

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.

35 litres is correct for 50kg cement.

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.

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

Minimum W/C ratio 0.38.
So required water= 50 x 0.38 = 19lt.
So required water= 50 x 0.38 = 19lt.

Explian how come .45?

Why w/c=0.45 taken? Please explain.

W/c ratio should be between .35 to .45.
