2018-6-5  2 of 6 46 Nevertheless, incorporation of PS as raw material into cement production is not yet studied. 47 Towards that, objective of this research is to determine the efficiency of incorporating PS as raw 48 material to produce cement by examining its free lime content (F-CaO) and its mineralogical 49 characterization compared to the ordinary Portland cement.

Modeling and Optimization of Cement Raw

Cement raw material and cement clinkers mainly contain four oxides: calcium oxide or lime (CaO), silica (SiO 2), alumina (Al 2 O 3), and iron oxide (Fe 2 O 3). The cement clinkers quality is evaluated by the above four oxides. Hence, ingredient ratio of cement raw material will affect the quality and property of cement clinker significantly.
