Today, blast furnace slag usage in the cement industry is known as slag cement. This term usually refers to either combinations of Portland cement and ground slag or to the ground slag alone. Within the current European cement standards, 14 listed cements may contain slag in different percentages by cement mass [8].
A promising type of steel slag for applications is the ladle furnace (LF) slag, which is also known as the basic slag, the reducing slag, the white slag, and the secondary refining slag. The LF slag is a byproduct from further refining molten steel after coming out of a basic oxygen furnace (BOF) or an electric arc furnace (EAF). The use of the LF slag in further …
