I am confused water measured in liter how much water required 1 bag cement?

Saksham said:   10 years ago
Exactly for normal concrete 22.5 liters are required.

Rupesh Hunde said:   10 years ago
Water requires= (45% of cement+25% of filling gel pores).

Water requires= (45%*50 + 25%*50) =35 kg/litre.

If weight of water is 35 Kg the W/C ratio is 0.7, How?

Er. Rakesh Siwach said:   10 years ago
Maximum W/C Ratio = 0.7.

Minimum W/C Ratio = 0.2.

The result for maximum w/c ratio is 35 kg/bag.

I think as per IS Code maximum w/c ratio allowed is 0.5.

Generally, we use 35% water of cement.
Then 1 beg cement means 50 kg cement and 35% of 50 kg is 50*35/100= 17.5 kg should be maximum 21 kg water.

Then w/c is 21/50 = .42, Thus C is the correct answer.

Maximum water-cement ratio as per IS10262 : 2009 is 0.55 And minimum water cement ratio is 0.38. It cannot be 35 kg. W/C ratio depends on the exposure condition of concrete but minimum water cement ratio is 0.38 for full hydration of concrete.

Arjun giri said:   9 years ago
W/c ratio should be 0.42.

So 0.42 * 50kg = 21 kg.

As per knowledge,

50 * 1440/1000 = 33.722 (Since 33.722 = 35 l).
