Particularities of structure formation of dispersed systems in the portland cement technology
In this publication, readers will find the results of the ana- lytical and experimental research of the physical and chemical pro- cesses in the consecutive formation of coagulation, condensation, and crystallization structures at the major technological stages of the present-day production of Portland cements. We have deter- mined the groups of the dispersed systems at the stages of prepara- tion of the source materials and making of the raw stuff mixture for wet, combined, and dry methods of production as well as for the grinding of clinker with additives and for making of cements based on the availability and quantitative ratio of the dispersed phase, wet and gaseous dispersed environment. We have shown the structural, mechanical, and rheological properties of the coagula- tion structure of cement slurries with typical composition based on limestone and polymineral clay. Readers will also find the particu- larities of the phase changes in the major rock-forming minerals of the raw stuff mixture in the process of the crystallization structure formation depending on the degree of the thermal treatment while baking at the maximum temperatures of 1110...1450 oC.
