Introduction The field of application of nano- and microheterogeneous systems in the construction industry is enormous – these are technologies for obtaining a variety of disperse products (powders, pastes, emulsions, suspensions, etc.), including composite (concrete, reinforced concrete, paving tiles, etc.) and nanocomposite (astringent, heat-insulating) of building materials, silicates (especially ceramics and glass), dispersed porous structures (styrofoam, primers) of plastics, glues, varnish-andpaint materials, etc. Since the particles of the dispersed phase and the surrounding dispersion medium in these systems have a very large phase interface (particle size of the dispersed phase is from fractions of microns to tens of nanometers (next nm)), with increasing dispersity, surface phenomena have a determining effect on the properties of disperse systems. Along with this, many physical properties (color, melting volumetric bodies do not depend on the size, point, electrical conductivity, density), which for large they acquire this dependence, when the particle size decreases below a certain border, which is usually 100 nm. On this basis, authors of educationalmethodical tutorial found it possible to do a conditional dimensional border and in the representation of material, divided into two parts: the first section is devoted to methods of obtaining and determining the characteristics of nanodispersed systems (particle size of 10 to 100 nm), the second is related to studies of the properties of microdispersed materials characterized by larger particles of the dispersed phase. The study guide includes the main theoretical material, presented the most modern in a concise form, reflecting possible ways of classifying and the properties of systems. In addition, the methodical sections of the guide describe how classical techniques perform a variety of experiments, and the original laboratory work carried out using 3
