Ordinary Portland Cements (OPC) 43 SUPER GRADE

Ordinary Portland Cement (OPC) is meticulously crafted through the blending of limestone with essential raw materials such as argillaceous, calcareous, and gypsum. This meticulously prepared mixture is then ground to achieve the desired fineness, resulting in OPC, a versatile cement renowned for its strength and reliability in construction applications.

The production of Ordinary Portland Cement (OPC) entails the careful preparation of a blend consisting of limestone and other crucial raw materials, including argillaceous, calcareous, and gypsum. Following thorough mixing, the mixture undergoes grinding to produce OPC, a foundational material widely utilized in construction projects for its exceptional performance and consistent quality.


Specifications of (OPC) 43 SUPER GRADE:

  • Initial strength is higher than PPC & Its initial setting time is 30 minutes and final setting time is 280 minutes. Its faster setting time helps faster construction.
  • Generates more heat than PPC in hydration reaction which makes it less suitable for mass casting.
  • OPC has a finiteness of 225 sq.m/kg. It has lower fineness than PPC. So, it has higher permeability resulting in lower durability.
  • Application/Uses It is suitable where fast construction is required & Grades available OPC 53 SUPER POWER GRADE & OPC 43 POWER GRADE.
