Modeling and Optimization of Cement Raw Materials Blending
Cement raw material and cement clinkers mainly contain four oxides: calcium oxide or lime (CaO), silica (SiO2), alumina (Al2O3), and iron oxide (Fe2O3). 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.
