What are the primary methods for utilizing steel slag as a secondary resource

1. Steel slag as road construction material

Steel slag features high bulk density, blocky form, rough surface, excellent stability, non-slip properties, high strength, wear resistance, corrosion resistance, durability, and strong bonding with asphalt. It is widely used as a substitute for natural crushed stone in various roadbed materials, engineering backfills, embankment reinforcement, and land reclamation projects.

2. Production of steel slag bricks

Steel slag bricks are manufactured using powdered steel slag and water-quenched steel slag as primary raw materials. These are blended with partial additions of blast furnace slag or fly ash, along with activators (lime or slaked lime), mixed with water, and processed through rolling, pressing, and autoclaving to form construction bricks.

3. Cement Production

Steel slag cement production primarily refers to its use as raw material in cement clinker formulation. Depending on raw material composition, cement types produced with steel slag include:

- Steel Slag-Slag Cement

- Steel Slag-Slag Portland Cement

- Steel Slag Zeolite Cement

- Steel Slag White Cement

4. Steel Slag as Agricultural Fertilizer and Acidic Soil Conditioner

Steel slag serves as a composite mineral fertilizer rich in calcium and phosphorus with multiple nutrients, offering both rapid and sustained effects. It is readily absorbed by plants. Containing trace elements like zinc, manganese, iron, and copper, it provides varying degrees of fertilizing benefits for different soils and crops deficient in these elements.
