Cement
OPC (Ordinary Portland cement) 53Grade
Ordinary Portland cement (OPC) 53 Grade is used in RCC and pre-stressed concrete of higher grades, cement grouts, instant plugging mortars etc. where initial higher strength is the criteria. Ordinary Portland cement, based on its minimum 28 day strength is further categorized as:
OPC 53 Grade (This type of cement should conform to IS-12269)
Advantages of OPC 53 Grade :
Speedy construction
Durable concrete
Economic concrete mix designs
Low percentages of Alkalies, chlorides, magnesia and free lime leads to the production of durable concrete.
