Investigations the relationship between the microstructures of cement clinker pahses and their grindabilities

The relationship between microstructures of cement clinker phases and their grindability at different production conditions were investigated by polorized microscope. The grindability indexes of these cement clinker materials were determined by Bond Grindability Method. The change in total porosity and their distribution, granuler structure of silicate phase crystals and their equivalent diameters were investigated. The result of this investigation showed that the size of crystals are more important than the alite and belite amount.
