GBFS is mainly used for grinding and producing GGBFS as well as blended cements with slag. GBFS is also used as an effective replacement of natural sand / crushed sand in concrete as a fine aggregate. GGBFS enhances long-term performance and durability characteristics in concrete while reducing life-cycle and maintenance costs.

Ground Granulated Blast Furnace Slag (GGBFS) GGBFS is formed when granulated blast furnace slag (GBFS) is further processed or ground using conventional cement clinker grinding technology. On a casual examination, GGBFS can be off-white in appearance and could pass for a powder fineness typically between 380m2/kg - 420m2/kg.

As shown in Figure 4, the compressive strength of 100% FA mix samples was less than those containing 25% and 50% GGBFS. However, the water requirement of GGBFS particles was high, due to the presence of calcium. Therefore, the compressive strength was reduced for the mix containing 100% GGBFS and was drier than other mixes.
