Application of Microwave Irradiation for Recycling of Blast Furnace Slag
free download
A blast furnace (BF) slag has been widely recycled at the civil engineering and construction field. However, the needs of recycled BF slag have become saturated and the development of a value added products is essential for establishing a sustainable society1).
