OPC Vs PPC in cement. Here's the difference between OPC and PPC: Composition. OPC is made from calcareous materials containing limestone, argillaceous materials …

The most widely used Portland cement is categorised into three types, OPC, PPC and PSC. In this article, we will cover the fundamentals of PSC, how it's …

PPC Cement. Developed out of OPC cement, ppc cement features a healthy addition of pozzolanic materials like slag, ash, clay, etc. With environmental compliance turning out to be a prime driver across industries, one of the most significant advantages that this type of cement brings to the table is a massively reduced amount of CO2 that's released during …

The lower the fineness, the higher the permeability. OPC has a fineness of 225 m2/kg. PPC has a fineness of 300 m2/Kg so it has lower permeability with higher durability. Workability of Concrete: Good workable concrete can be achieved using OPC, but the workability is fewer than PPC. Concrete made with PPC has more workability compared to OPC.

Cement in Nepal -PSC/PPC/OPC; Cement is a fundamental building material that serves as the binding agent in concrete, a key component in construction. Produced through the heating and grinding of a mixture of limestone, clay, and other minerals, cement forms a fine powder.
