Recycling techniques of steel slag and its utilization in green concrete to enhance properties and durability

Steel slag is a solid waste discharged in large quantities by the iron and steel industry. Steel slag includes a certain scale mineral such as C2S and C3S, and can be applied in cement and concrete as mineral admixtures. When super fine steel slag powder is mixed into concrete as an active admixture, concrete properties will be improved greatly so as to produce high performance concrete. The resistance to abrasion and durability, the workability and mechanical properties of the concrete therefore can all be enhanced. When compound mineral admixtures with steel slag powder and blast-furnace slag powder are mixed into concrete, the performance of concrete can be improved further due to the synergistic effect and activation of each other. Therefore, the mineral admixture will be a perfect component of green concrete and its utilization will be a valuable resource for recycling.
