With the rise in awareness of environmental issues and diminishing natural resources, the focus of construction industry has shifted towards eco-friendly materials and technologies. Our commitment to environmental causes has motivated us to use by-products like blast furnace slag from steel, which are effective not only in pollution management but also in natural resource conservation. Hence, JSW Cement is the leading manufacturer of ‘green cement’ in India. The use of slag in concrete has replaced partially the Ordinary Portland Cement (OPC). As a common practice, blast furnace slag is incorporated in Portland cement production for environmental, technical and economical benefits. Before JSW Cement’s entry in the market, ‘green cement’ was virtually unheard in southern and western India.
Portland Slag Cement (PSC)
Portland Slag Cement, commonly known as PSC, is blended cement. Slag is, essentially, a non-metallic product comprising of more than 90% glass with silicates and alumino-silicates of lime. At JSW Cement, we 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 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.
The multi-fold advantages of PSC
PSC’s inherent chemistry gives it several advantages over ordinary cement. Apart from being more environment-friendly, it offers;
Ultimate compressive strength
Excellent resistance to Chloride & Sulphate attacks
Low risk of cracking
Better compatibility with all types of admixtures
Ease of pumping
Better resistance against alkali-silica reaction
Minimised shrinkage cracks
Where PSC can be used?
All types of residential, commercial and industrial projects
