Minimum water cement ratio is 0.45.
with that 50kg(1bag) x 0.45= 22.5 is the correct answer.
with that 50kg(1bag) x 0.45= 22.5 is the correct answer.

In the process of hydration of OPC. What is the water requirement to complete the chemical reaction ?

Simple,
Vol of cement bag of 50 Kg = 0.035 m3.
And, per 1 m3 we need 1000Kg of water.
So, Water required = 1000*0.035 = 35 Kg.
Since there is no mention about w/c ratio.
Vol of cement bag of 50 Kg = 0.035 m3.
And, per 1 m3 we need 1000Kg of water.
So, Water required = 1000*0.035 = 35 Kg.
Since there is no mention about w/c ratio.

1m^3 = 1000kg or 1000lit.
1m^3 = density of cement / weight of one bag.
1m^3 = 1440/50=28.8 bags.
28.8bags = 1000kg.
1bag = 1000/28.8 = 34.7~ 35kg or 35 lit.
So Answer is correct.

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%.
