· It was found that the magnetic separated BOF slag with low MgO and alkali contents should be used as clinker raw materials along with blast furnace slag and lime stone. Blended cement made with 6% BOF slag, 37% iron slag, 57% limestone and 3% gypsum exhibited satisfactory performance, as compared with ordinary Portland cement ( Monshi and Asgarani, 1999 ).

CEMENT 101
· Modern Portland cement is termed 'Ordinary Portland Cement' (OPC) and is made by combining limestone or chalk (CaCO 3) with sand (SiO 2), clay and other materials (eg: Al 2 O 3, Fe 2 O 3, TiO 2) in a kiln at temperatures in the region of °C. 15 The mixture first undergoes decarbonation in which CO 2 is lost from the limestone to produce calcium oxide (CaO).
