Ultimate strength of cement is provided by
Tricalcium silicate
Di-calcium silicate
Tri-calcium aluminate
Tetra calcium alumino ferrite
Correct answer is B
Dicalcium Silicate (C2S): This compound will undergo reaction slowly. It is responsible for the ultimate strength of concrete. This is also called as Belite. The heat of hydration is 260 J/Cal. Its proportion is 25 - 40%.
