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.
