The product
OPC 53 is the cement engineers specify for columns, beams, slabs, precast and prestressed work. A tightly controlled clinker and a fine grind give it high early strength and a steady, predictable set.
Every batch is tested at our plant laboratory before it is bagged, and the batch number on each sack links to its test certificate.
Technical data
Portland clinker and gypsum. No fillers.
