OPC 43 cement:
OPC 43 cement shall conform to IS:8112-1989 and the designed strength of 28 days shall be minimum 43 MPa
OPC (43 Grade) can be used in all kind of Concrete constructions – such as RCC, precast concrete and prestressed concrete, Slip form constructions, all kinds of Masonry works, manufacture of cement based products such as pipes, tiles, blocks etc
