Low CO2 Concrete

Slag cement requires nearly 90 percent less energy to produce than an equivalent amount of Portland cement. Reducing the use of Portland cement in concrete by substituting a portion of it with slag reduces the embodied energy in a cubic yard of concrete by 30 to 48 percent. Reduced Material Extraction. Raw materials for Portland cement are ...

Portland Slag Cement – Quality Polytech

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.
