Use of Slags in the Production of Portland Cement Clinker ...

2019-8-28 · The strength of cements was defined in small samples from cement paste (1:0) with water-cement ratio of 0.28. The results given in Table 3 show that the use of slags in raw materials instead of clay positively affects the activity of clinkers. The strength improvement within a 28-day interval at full replacement of a clay component with slag made 62%.

Modification of Basic Oxygen Furnace Slag for Cement ...

2017-6-19 · The use of steelmaking slag without chemical modification presents a deleterious effect on cement mechanical properties, due to the expansion caused by the presence of free CaO and MgO in the slag. This work deals with the modification of one basic oxygen furnace (BOF) slag with the objective of making it an appropriate additive in blended cement formulations. Two different modified slags were ...
