SLAG BASED CONCRETE

Ladle furnace slag is a by-product of iron- and steelmaking industry produced in the final stages of steelmaking during the separation of the molten iron and steel from impurities. The increase in the steel consumption is thus the cause of the slag generating process. As Ladle furnace slag considered a heavy metals wastewaters adsorption agent as it is a significant savings in the natural resources by having high adsorption capacity, and low cost process due to their abundance in nature and less processing requirements. However, this way of using this by-product consider as a setback because it does not consume all the LFS properties. Steel slag is typically composed of silicates (3CaO⋅SiO2 and 2CaO⋅SiO2 phase), oxides (CaO–FeO–MnO–MgO) these types of chemical composition consider as a good cement replacement material. Concrete is the single most widely used material in the world and the Concrete production contributes 5 percent of annual anthropogenic global CO2 production.
