Steel slag is the by-product during the separation of molten steel from impurities in the steel-making furnace. The basic oxygen furnace (BOF) slag, electric arc furnace (EAF) slag, and ladle furnace (LF) slag are three major types of SS produced in the steelmaking processes.As drawn in Fig. 2, BOF slag and EAF slag are both produced …Web

Data are unavailable on actual U.S. ferrous slag production, but domestic slag sales1 in 2019 were estimated to be 17 million tons valued at about $470 million. Blast furnace slag was about 50% of the tonnage sold and accounted for 88% of the total value of slag, most of which was granulated. Steel slag produced from basic oxygen and electric ...Web

Steel slag is generally regarded as a supplementary cementitious material in cement-based materials, which is conducive to the realization of the goal of carbon peak and carbon neutralization. …Web

Several studies have explored the potential use of steel slags as SCM by replacing the cement in cement-based composites [46], [116], [198] since steel slag has chemical and mineralogical composition similar to Portland cement clinker [219].Web

The compressive strength of concrete using steelmaking slag as fine aggregates is around 1.1 to 1.3 times of common concrete. Further, steelmaking slag concrete shows similar fire resistance to the river aggregate mixture up to 400 deg C, and much improved fire resistance at high-temperature ranges.Web

05 October 2023.
