Granulated blast furnace slag is produced by injecting pressurized water to rapidly cool the molten slag produced in the blast furnace. This product is popular in Japan and other countries for use as raw material for cement.

Ground granulated blast furnace slag produced by pulverizing granulated blast furnace slag is mixed with Portland cement to produce Portland blast furnace slag cement. Portland blast furnace slag cement is economical and environmentally friendly because it conserves resources and energy, leading to reduction in CO₂ emissions.

By using granulated blast furnace slag, consumption of limestone, the main raw material of cement is reduced by approximately 40%. Also, you can omit the calcinating process of limestone reducing energy consumption by approximately 40%. These factors result in reducing CO₂ emissions produced during the manufacturing process by approximately 42%.
