Color White and Grey Ground Granulated Blast Furnace Slag, Model NameNumber Granulated Slag

Ground granulated blast, Furnace slag ggbs or ggbfs slag is byproduct of ferrous metals and alloys manufacturing process. It contains the entire basic constituent of opc but not exactly in the same ratio and chemical form. Slag itself has no cementing property but when mixed with opc or activated chemically it develops hydraulic features comparable to cement. The calcium oxide cao found in slag is tied up as calcium aluminates, Calcium silicate and calcium aluminosilicate. Although these compounds are not identical to those found in portland cement i. E. Tricalcium silicate, Tricalcium aluminate, Etc, They hydrate when activated by calcium hydroxide generated during the hydration of portland cement. Since ground granulated blast furnace slag is almost 100% glassy, It is generally more reactive. This process of quenching is called granulation because it produces glassy granules similar in appearance to having excellent, Coarse sand cementitious property when ground to high fineness blended with cement.
