Abstract

The article presents theoretical study of structure formation of coke dust in cement composites with the introduction of fine-grained particles on the basis of the fundamental propositions of colloid chemistry and physicochemical mechanics of disperse systems. According to optical microscopy and magnification of fragments of characteristic structure we defined geometric properties and the nature of the microstructure of the structural elements of coal, coke and coke dust particles. It was shown that the microstructure of coke during its manufacturing does not change and corresponds exactly to the microstructure of coal. It was determined that the interaction of coke particles with elements of the structure of cement stone is carried out under the influence of their main components - a mixed coal electroconductivity and surface electrical properties. The article represents the theory of influence of coke dust on the processes of structure formation of cement stone, mortar and concrete. It was determined that during the hardening of cement stone the particles of coke dust will adagulate to the surface of grain filler
