Slag cement (also called ground granulated blast furnace slag) is a hydraulic cement produced during the reduction of iron ore to iron in a blast furnace. Molten slag is tapped from a blast furnace, rapidly quenched with water ("granulated"), dried and ground to a fine powder.

Slag is the glasslike byproduct left over after a desired metal has been separated from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re .

The iron is used to produce steel, and the molten slag is converted to a cementlike material by rapidly cooling it with water. This rapid cooling, called quenching, creates glassy granules, which are then ground into the fine powder known as slag cement. Slag cement is as old as ironmaking itself.

Effects of steel slag powder on the workability and mechanical properties of concrete were investigated by Li YunFeng et al [8]. Mechanical properties can be improved further due to the synergistic effect and mutual activation when compound mineral admixtures with steel slag powder and blast furnace slag powder mixed with concrete, as a result of this study.

Groundgranulated blast furnace slag (GGBS): Groundgranulated blast furnace slag is a byproduct from the blast furnaces used in the iron manufacturing industry. GGBS is obtained by quenching molten iron slag (a byproduct of iron and steel making) in water or steam, to produce granular product then dried and ground into a fine powder.

The results indicate that, with the increasing slag content, the setting time decreases; the compressive strength firstly increases and then decreases after the slag replacement exceeds a critical value. Additionally, an optimum content for limestone powder in the metakaolinslag blends is around 15%.
