JSW PSC is blended cement. It is the most suitable cement for Infrastructure Projects because of its high flexural strength.
Maximum strength, low risk of cracking, improved workability, and superior finish are the advantages of PSC.
Portland Slag Cement (PSC) is manufactured by either inter-grinding in the Portland cement clinker, Gypsum & Granulated Slag or blending the Ground Granulated Blast Furnace Slag (GGBS) with Ordinary Portland Cement by means of mechanical blenders. At JSW Cement, they use superior quality slag produced at our steel manufacturing plant, conforming to IS: 12089 standards for producing PSC. It is created with a combination of 45- 50% slag, 45% – 50% clinker, and 3-5% gypsum. PSC has been voted as the most suitable cement for concrete pavements, mass concrete applications, high performance or high strength concrete, structures and foundations, pre-cast concrete such as pipe & block, concrete exposed to sea water and marine application.
