W/c ratio is 0.5 -0.7 acc to code.
35/50= 0.7.
35/50= 0.7.

Cement 500= 0.35 m3 (50 kg cement =0.035 m3 cement)
Water Req for cement 38 %
= 0.35 * 38/woo
= 0.133 m3 Water
From Water Density.
1000 kg/m3 = (kg/0.133 m3)
Water = 133 kg.

Simple, the unit should be in litres not kg so the answer is correct, only it should be in litres.

The maximum quantity of water = 65% of the weight of cement.
i.e 65/100*50 = 32 litre.
Hence, 32 litre is the correct answer.
i.e 65/100*50 = 32 litre.
Hence, 32 litre is the correct answer.

For a general purpose, w/c ratio is .45.
So, water required for 1 bag of cement (=50kg) is 22.5 ltrs.
So, water required for 1 bag of cement (=50kg) is 22.5 ltrs.

As per ACI, Minimum percentage of water for hydration of cement is 0.4.
50 x 0.4 = 20 kg.
50 x 0.4 = 20 kg.

Tri-calcium silicate requires 24% and Dicalcium silicate requires 21% (only weight of Cement)
Average of 23% of water by weight of cement is required for chemical reaction with portland cement compound.
15% by weight of cement is required to fill up gel- pores.
Total requirements of water is 23 + 15= 38%.
