Ambe PSC Cement

Portland Slag Cement, commonly known as PSC, is blended cement. Slag is, essentially, a non-meta-llic product comprising of more than 90% glass with silicates and alumino-silicates of lime. JSW Cement, users superior quality slag produced at it’s steel manufacturing plant, conforming to IS: 12089 standards for producing PSC. It is created with a combination of upto 45- 50% slag, 45% – 50% clinker, and 3-5% gypsum. PSC has been voted as the most suitable cement for mass construction because of its low heat of hydration.

This cement is produced by mixing Portland cement clinker, gypsum and granulated Blast Furnace slag in suitable proportions and grinding the mixture to get a thorough and intimate mixture between the constituents. According to the control over physical and chemical specification, slag is mixed up to 25-65%. Slag is a byproduct in the manufacture of pig iron. Chemically, slag is a mixture of lime, silica and alumina, that is, the same oxides that make up Portland cement. Cementitious properties are generated when ground granulated slag reacts with water.

Using slag cement to replace a portion of Portland cement in a concrete mixture is an efficient way to make concrete more consistent. Among the measurable improvements are higher workability, higher finishability, lower permeability, improved resistance to aggressive chemicals, more consistent plastic and hardened properties, flexural strengths, and highest compressive strength.
