The ground granulated blast furnace slag (GGBS) is the waste slag produced when smelting pig iron in steel plants. After quenching and granulation, the slag will be ground in the slag vertical roller mill to become GGBS powders.
The ground granulated blast furnace slag (GGBS) is mainly an amorphous vitreous structure and contains a small number of crystalline minerals. Due to the large content of glass in slag, the structure is in a high-energy state, unstable and has great potential activity, so it needs to be ground to give full play to its potential activity. It is a kind of high-quality concrete admixture. The ground granulated blast furnace slag (GGBS) is usually added to cement as an admixture to produce blast furnace slag cement. The GGBS powder can significantly improve the comprehensive properties of concrete and cement products by replacing the amount of cement in them for various purposes.

The advantages of adding slag powder to cement mainly include:
1) It can greatly improve the strength of cement concrete and prepare ultra-high-strength cement concrete;
2) It can effectively inhibit the alkali-aggregate reaction performance of cement concrete and improve the durability of cement concrete;
3) It can effectively improve the anti seawater erosion performance of cement concrete, especially suitable for anti seawater engineering;
4) It can significantly reduce the bleeding of cement concrete and improve the workability of concrete;
5) It can significantly improve the compactness and impermeability of cement concrete.
