What is sulphate attack and its effect?

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.

Ordinary portland cement is use to new road pavements and rapid hardening cement road repair use.

Ordinary portland cement is the correct answer.

In road pavement we should use rapid hardening cement because road is a very busy line and we can't free road for long time so to open road for use quickly we use rapid hardening cement.

For road pavement - rapid hardening cement.

For massive concrete - low heat cement.

For canal lining or sever - portland slag cement.

Rapid hardening is used for repair work. But for new construction OPC is use.

** Low heat cement is used for massive works like dams, retaining walls, etc.

** Ordinary Portland Cement is used for general works except the area having sulphate attack(OPC is least resistant to Sulphate attack).
