Rapair work - rapid hardening cement.

Road construction- low heat cement (resistance to sulphate and chemical attack).

Rapid Hardening cement is used for repairing works.
OPC is use for all new construction works.
So, OPC is correct answer.

Yes, BFSC use for practical purposes for road construction.

Rapid hardening cement is used in the repair of roads & Blast furnace slag cement is used in the construction of road b/c road payment are constructed over soil and soil is generally rich in sulphates and BFSC has good resistance against sulphate attack.

@Raj.

Yes, you are correct.

Blast furnace slag cement is used in road pavements.

Raj said:   3 years ago
I think blast furnance cement use because pavement laid on soil. Sulphate present in soil so this cement protect.

To open the traffic as possible rapid hardening cement.

Yoga said:   3 years ago
As per my knowledge, Opc is used.

What is sulphate attack and its effect?

Vikram kadam said:   5 years ago
Rapid hardening is correct because the road is open to traffic in minimum days and it also have one day strength equal to 3 day strength of opc.
