“…The parameters characterizing the structure of the hydrated calcium silicate particles, the ratio of the free and bound water the presence of pores and their shape and size distribution, i.e. the structural parameters of the material at micro and nanoscale [7][8][9], affect the properties of the resulting cement brick [12,13]. It is possible to obtain certain specified properties of building materials with cement by using sludge as additives to be fillers or modifiers.…”

Abstract.A large group of industrial wastes from water purification, treatment and softening has been considered. The reference is made to the fact that slurries are a unique man-made product technologically ready for use and constantly restocking. Slurries have been classified by conditions of the formation, composition, chemical and physical properties. The nanoscale structural parameters of the slurry particles (the size distribution and fractal dimension) have been determined by the neutron small-angle scattering method. The conducted researches allow slurries to be considered a nanotechnogenic raw material. The use of slurries as additives in the building material production process reduces the harmful influence of industrial wastes on the environment and creates a significant reserve of material and energy resources in the construction industry.

Abstract. The research of the structure formation process on a nanolevel of the samples of hydrated Portland cement compositions containing the modifying additives has been conducted with the help of small angle neutron scattering method. Carbonate and aluminum alkaline slimes as well as the complex additives containing surfactants were used as additives. The influence of slimes and surfactants on structural parameters change of Portland cement compositions of the average size of the disseminating objects, fractal dimension samples is considered. These Portland cement compositions are shown to be fractal clusters.

“…For the cement composite materials, application of nanomodifiers is an effective method of such control. Nanomodifiers impact the cement hydration process and change the rate between chemical components in hardening cement paste [1][2][3][4][5][6][7][8][9][10]. Introduction of presynthesized nanoparticles together with the water is one of the most common methods of building materials nanomodification.…”
