The goal of the current study is to determine the dissolving effect of slag in water. Five percentage values of slag were taken up for the study: 0%, 2.5%, 5%, 10%, and 20%. The study is based on two methods of mixing. The first method is the traditional mixing process, which involves addition of slag directly with other concrete proportions …
Blast furnace (BF) slag, which is the main byproduct in the ironmaking process, contains large amounts of sensible heat. To recover the heat, a new waste heat-recovery system—granulating molten BF slag by rotary multinozzles cup atomizer and pyrolyzing printed circuited board with obtained hot BF slag particle—was proposed in …
