What about sulphate resisting cement?

I guess they have better resistance to sulphate attack. Am I right?

Reja said:   8 years ago
Portland pozzolana cement and sulphate resisting cement can be used. So here, option A is right.

Yes PPC are used in sea water but given option high alumina cement. So high alumina cement.

Basu said:   1 decade ago
Alumina has better resistance against salt content water and it increase heat of hydration.

IS 456:2000, Cl 8.2.8.

For sea water:-
PCC - M20.
RCC - M30.

Use PPC or Slag cement.

Rapid hardning cement is used as sudden hardening is important for such structures.

Sea & underwater work -HAC.
Marine work-PPC.
Running water-QUICK SETTING PC.

As per IS code 8.2.8 the use of slag or pozzolana cement seawater.

Why there is no use of quick-setting cement in sea structures?

Blast furnace slage cement is use in marine work.
