|** 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).

|For road pavement - rapid hardening cement.
For massive concrete - low heat cement.
For canal lining or sever - portland slag cement.

|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.|

|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.|
