Portland Slag Cement (PSC)
PSC consists of 25-70% granulated slag, 3% gypsum and the rest is clinker. Granulated slag is, essentially, a non-metallic product comprising more than 90% glass content with silicates and alumino-silicates of lime. At Sagar Cement, we use superior quality slag conforming to IS: 12089 standards for producing PSC.
In England, natural rock formations on the Isle of Portland possess remarkable hydraulic properties. Once this particular type of rock has water added, it hardens and strengthens even further and it has now become one of the most widespread types of cement, known as Portland.
Higher level of compressive strengths in concrete when compared to OPC
Higher flexural strength to concrete, which enhances its structural stiffness and minimises load deflections
Reduces the ingression of harmful substances such as chlorides and sulphates due to low permeability
Environment-friendly due to reduced GHG emissions
