Ground Granulated Blast Furnace Slag (GGBFS) is a by-product obtained during the manufacturing of iron in blast furnaces. This material is created when molten iron slag is quenched with water, resulting in a glassy, granular product. GGBFS is commonly used in the construction industry as a supplementary cementitious material due to its latent hydraulic properties, which allow it to react with water to form cementitious compounds. When mixed with Portland cement, it enhances the durability and strength of concrete and reduces its permeability. The demand for GGBFS correlates with the health of the iron and steel industry, as the production of iron inherently generates slag. This market is influenced by government regulations related to sustainable construction practices and the recycling of industrial by-products. The usage of GGBFS has been encouraged to reduce the environmental footprint of construction activities by lowering carbon dioxide emissions and minimizing the consumption of natural resources such as limestone and shale.
Prominent companies that produce or supply GGBFS include Ecocem, Nippon Steel & Sumitomo Metal Corporation, Tata Steel, JSW Steel, and Lehigh Hanson. These firms are noted for their efforts in providing eco-friendly construction materials and are integral players in the field of sustainable building practices. Show Less Read more
