Good to know
Questions, answered
Ordering, delivery, storage and choosing the right grade.
Use OPC 53 for structural concrete such as columns, beams and slabs. OPC 43 suits general concrete, brickwork and plaster. PPC and PSC are best for foundations, mass pours and anything exposed to water or salts.
