Therate of alite formation is even higher than the rateestablished for mixes mineralized with CaF2. Onthe other hand, presence of these compounds allows theraw material to sinter at temperatures between 1350 and1400 °C. The white cement clinker may thus beproduced at temperatures lower by about 200 °C belowthe usual sintering temperature of traditional rawmaterial mixes for white cement. This of course bringsabout substantial savings in energy not only in themanufacture of white cement

Abstract. Concrete grinding residue is the waste product resulting from the grinding, cutting, and resurfacing of concrete pavement. Potential beneficial applications for concrete grinding residue include use as a soil amendment and as a construction material, including as an additive to Portland cement concrete.

Modeling and Optimization of Cement Raw Materials

This paper focuses on modelling and solving the ingredient ratio optimization problem in cement raw material blending process. A general nonlinear time-varying (G-NLTV) model is established for cement raw material blending process via considering chemical composition, feed flow fluctuation, and various craft and production constraints. Different objective functions are presented to acquire
