Ultimate strength to cement is provided by
Tricalcium silicate
Di-calcium silicate
Tri-calcium aluminate
Tetra calcium alumino ferrite.
Answer: Option
Explanation:
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%.

c3s and c2s are major strength giving component in cement. For same amount of ater added (23%). c2a give more amount of c-s-h gel which bind cement molecule together.

c3a provide early setting characteristics while c2a react slowly but provide strength while hardening process.

Please, give theMajor differences of tri calcium silicate and Di-calcium silicate.

Dicalcium silicate provides Ultimate strength i.e. strength after 7days and tricalcium silicate provides early strength ie, before 7 days.

The answer is c2s, because same moles c3s and c2s, c2s will. Form more c-s-h gel resulting in long-term strength.

The dicalcium silicate is provided initially low strength but with the time it increases the strength of cement.
