Thanks @Lalit chate.
The correct answer is indeed 130kg.
The correct answer is indeed 130kg.

Total water requirements for Complete the chemical reaction Is 38 %,
So, 38 * 500 = 19.
Because 23% of the water required for hydration process & 15 water is required for filling the gell pores.
So, total (23+15) = 38% water is required to complete the total chemical reaction.
So, 38 * 500 = 19.

For complete hydration, 38% water is needed.
So 500*38/100 = 190 then how the answer is 130?
So 500*38/100 = 190 then how the answer is 130?

For hydration of cement 23% of water is required.
So, for 500 kg cement, the answer should be 115kg.
So, for 500 kg cement, the answer should be 115kg.

It has been further estimated that about 15% by weight of cement is required to fill up the gel pores and 23% is used for hydation of cement process. So total 38% is required.

0.35*0.38 = 0.133.
0.133 * 1000 = 133kg.
0.133 * 1000 = 133kg.

% wt of water required for full hydration is 38% by wt of cement.
i.e., 38*150/100 = 57 kg.
i.e., 38*150/100 = 57 kg.

Normally the standard weight of cement bag = 50kg it requires 35 litres of water.
So 500 kg of cement bag required = 500*35/50 = 135 litres of water.
So 500 kg of cement bag required = 500*35/50 = 135 litres of water.

Cement 500= 0.33 m3 ( 50 kg cement =0.033 m3 cement).
Water Req for cement 38 %.
= 0.33 * 38/woo.
= 0.127 m3 Water.
From Water Density.
1000 kg/m3 = (kg/0.127 m3).
Water = 127 kg.
