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%.

Tri- calcium silicate (C3S) has the property of hydrating rapidly and is responsible for providing not only early strength but also the ultimate strength.

Ajay Gawade said:   3 years ago
Initial strength to cement is provided by C3S and later strength is provided by C2S.

So, ultimate strength to cement is provided by both C3S & C2S.

Di- Calcium silicate responsible for the lateral strength of cement. C2S.

Tricalcium calcium silicate responsible Early strength of cement. C3S.

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

Option B is correct answer. Ultimate strength is due to di-calcium. Tri calcium provides initial setting. Then ultimate strength starts.

Tri calcium cement contributes in initial strength of concrete whereas di calcium silicate contributes in strength after 7 days.

Tri-calcium silicate is response for early developing strength. So, why gives ultimate strength a di-calcium silicate.

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.
