Types of cements :-
Ordinary Portland cement (OPC) - IS Code – 269-1976 – It is suitable for general construction Low heat cement – IS Code – 269-1976 – It is useful for large construction Rapid hardening cement - IS Code – 8041-1990 – It can be used for eliminating formwork rapidly
Pozzolona cement – IS Code – 1489-1991 – It has good resistance capacity against chemical reaction High strength cement – IS Code – 8112-1989 – It is applied in prestressed concrete Hydrophobic cement – IS Code – 8043-1991 – It is applicable for water-proof construction
Grade of cement is based on the crushing strength of a cement mortar cube with size 70.71mm having surface area of 51 cm2 that is tested in 28 days.
