Steel slag practical application in life
Steel slag is a solid waste produced by extracting impurities with lime during steelmaking, and the discharge is about 10% to 15% of steel production. The characteristics of the steel slag itself, such as hydraulic hardness and wear resistance, give the steel slag aggregate a characteristic that is not possessed by a series of natural aggregates. However, the current shortage of natural ...
