AbstractAbout AuthorsReferences
Composite cement is a modern building material, which contains a mineral component that improves the technological properties of cement. The production and application of composite cements with the use of mineral components of technogenic origin is gaining increased importance due to their advantages both from an economic and ecological point of view. When grinding the components of composite cement in an energetically stressed centrifugal impact mill, agglomerates of particles are formed – mechano-composites that affect the properties of the finished product. A phenomenological mathematical model of structural transformations of a powder mixture of components when manufacturing the composite cement is proposed. The kinetics of changes in the sizes of particles and mechano-composites, as well as their concentrations in composite cement, have been studied by analytical and numerical methods. The main parameters of the grinding process, which make it possible to obtain composite cement with the specified characteristics, have been identified.
