Ground Granulated Blast Furnace Slag (GGBFS) in Concrete
The use of Ground Granulated Blast Furnace Slag reduces the heat generated during the hydration of cementitious materials. This is especially valuable in large concrete pours, as it minimizes the risk of thermal cracking. GGBFS is used as combination material with cement in most of the countries. Further, it can be added with cement in …
