Modeling and Optimization of Cement Raw Materials

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.
