Ordinary Portland Cement (OPC53 & OPC43)

Polad OPC is perfect for ordinary construction because of its durability and strength. Unique properties of the OPC53 and OPC43 grades include:

• At all phases, great fineness is required for high strength growth.
• The low hydration heat promotes crack-free fabrication.
• Low C3A concentration minimises material deterioration and the likelihood of premature cracking.
• Corrosion is prevented by a low chloride concentration.
• Low alkali concentration improves compressive strength and increases setting time.
