Basic Oxygen Furnace slag the main by product of steelmaking process presents still low utilization rate due to its limitations as a partial replacement for cement The Basic slag is a co product of steelmaking and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route To flux the silica produced during steelmaking limestone and/or dolomite are added as well as other types of slag conditioners such as calcium aluminate or fluorspar
