It is necessary to ball-mill granulated blast furnace slag (GBFS) for 12 min or longer to achieve a high surface area, over 1.9688 m 2 /g, and clinker for 24–30 min to achieve a surface area of over 2.2699 m 2 /g, as well as to maintain the water-to-cement ratio between 0.45 and 0.64.
Ground granulated blast furnace slag also has a lower heat of hydration and, hence, generates less heat during concrete production and curing. GGBFS is a desirable material to use in mass concrete placements where control of temperatures is an issue. GGBFS can be used instead of cement with the ratios from 10% to 90%.
