Ground Granulated Blast Furnace Slag (ggbs) Chemical
Slag. Ground granulated blast furnace slag, commonly referred to as slag or slag cement, is a by product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the hydrated cement paste (pozzolanic reaction), resulting in a.SLAG Ground granulated blast furnace slag (Fig. 3 5), also called slag cement, is made from iron blast furnace slag it is a nonmetallic hydraulic cement consisting essentially of sili cates and aluminosilicates of calcium developed in a molten condition simultaneously with iron in a blast furnace. The molten slag at a temperature of about 1500 C.
