Table 2 compares the composition of a typical ground granulated blast-furnace slag to that of a typical Type I Portland cement, a typical Class C fly ash and a typical Class F fly ash. You will note that the GGBFS and the two fly ashes have the same kinds of oxides as the cement, which means that when GGBFS or fly ash is added to concrete, materials similar to Portland cement are being introduced into the

The efficiency, which the molten blast furnace slag is rapidly chilled, as well as the chemical composition of the slag source, largely determines its cementitious properties for use in concrete. After the granulated blast furnace slag is formed, it must be dewatered, dried and ground, using processes similar to those used with Portland cement clinker to make Portland cement.
