Get PriceEstimation of the Environmental Impact for Recycling Blast
Blast furnace (BF) slag has been widely recycled by civil engineering and construction industries. However, the amount of recycled BF slag has now reached the saturation point, and the development of new value-added products will be essential for promoting sustainable societies. 1) Recently, a hydrothermal reaction was proposed as a potential approach for solving this problem. 2) In general
