Drainage from steel slag disposal sites can be extremely alkaline and a source of pollution to surface and ground waters. Data is presented detailing the hydrogeochemistry of seven highly alkaline (pH > 10) steel slag surface discharges in the UK. While there is the consistent presence of Ca–OH type groundwater in all the …

Steel slag's usage is related to its physico-chemical characteristics. The density of steel slag is 3.3–3.6 g/cm 3. Steel slag is hard because of its high Fe amount and is highly resistant to corrosion. The grindability index of steel slag is 0.7 [38]. Steel slag primarily consists of SiO 2, CaO, Fe 2 O 3, FeO, Al 2 O 3, MgO, MnO, and P 2 O 5 ...
