  • Converting Granulated Blast Furnace Slag into Fine Aggregate

    Slag Granulation is primarily affected by water temperature, water pressure and water flow rate. When the material solidifies under slow cooling conditions, escaping gases leave behind micro pores in the cooled mass. When formed under controlled rapid cooling, the slag tends to be hard and dense, making it suitable for use in all concrete
