Superfine particles have been used as mineral admixtures to enhance physical properties, mechanical properties, and durability of concrete in a lot of research. In this study, superfine steel slag (FSS) and superfine phosphorus slag (FPS) were ground to 643 and 657 m2 kg−1, respectively. The water-to-binder (W/B) ratios were set as 0.45 …

In the hot splash method for a slag line; slag is first transported to a hot splash field with a slag pot, and the steel slag is tipped over three to four days after being sprinkled with water to cool it. After then, most of the steel slag is broken by self-dispeling and slag is transported to the magnetic separation line.
