High Quality Granulated Blast Furnace Slag

The main components of granulated blast furnace slag include SiO2, Al2O3, CaO, MgO and other elements. Among them, SiO2 and Al2O3 are the main components, and their proportions in the total components are relatively high, reaching 30%~40% and 10%~20% respectively. The contents of CaO and MgO are low, generally accounting for 5% to 10% and 1% to 3% of the total ingredients respectively.

Construction field:

Granulated blast furnace slag can be used as cement raw material. Because it contains a large amount of glass phase, it can be used to replace clinker in cement, thereby saving raw material resources and reducing energy consumption.

Agricultural field:

Granulated blast furnace slag can also be used as fertilizer. The components such as CaO and MgO can provide the nutrients needed by crops. At the same time, it is rich in trace elements and can also promote plant growth.

Environmental field:

Granulated blast furnace slag can also be used as filler, landfills and road construction to reduce waste and environmental pollution.

In addition, granulated blast furnace slag can also be used as a raw material to return to the steel production process and used as a raw material for iron or steel making to improve resource utilization; it can also be mixed with additives such as cement and lime for solidification treatment to form a solid body and reduce the production of granulated blast furnace slag. Volume, easy to transport and stack; or through processes such as crushing, mixing, and pressing, it can be made into brick-shaped solid waste for use as building materials or roadbed fillers; the iron oxide in it can also be used as a soil conditioner to increase the pH of the soil and improve the quality of the soil. soil structure.
