“…Studies on chemical modification [19], heat treatment [20], electrochemical action [21], and electrostatic enrichment [22] make it possible to increase the selectivity of action and sorption capacity. The actual direction of modification of building materials is the use of plasma technologies [23][24][25]. This work is a continuation of previously initiated studies on the modification of sorbents based on natural zeolites and bentonites [26][27][28].…”

In residential and industrial buildings, a special air environment is formed, which contains gas shaped toxic chemical compounds. A significant part of such substances comes from finishing polymer containing materials. Virtually all polymeric materials release certain toxic chemical compounds into the air. The methods and methods of air cleaning are different. One of the ways to solve the problem associated with providing the required standards for the quality of indoor air is the development and use of new efficient building materials using aggregates that have a high sorption capacity. The paper presents the results of a study of the effect of low temperature non-equilibrium plasma on the sorption characteristics of aggregates based on diatomite earth. Studies have been conducted on samples of natural diatomite and quartz sand. When activated by low temperature nonequilibrium plasma, the structure changes, which leads to an increase in the sorption characteristics of the samples under study.

“…Plasma-chemical modification is one of the promising technologies of creating protective-decorative coatings in the manufacture of finishing construction materials for building and construction faces (Bondarenko et al 2018a, b;Bessmertny et al 2018;Bondarenko et al 2016;Volokitin et al 2016). Dehydration, melt formation and accumulation during plasma melting take second fractions, and the surface is heated up to 2000°C.…”

Peculiarities of Portland cement dehydration in different hydrate phases with sodium water glass have been given. Three endoeffects were determined during non-isothermal heating, connected with ettringite dehydration and water extraction at temperature ranges 98.7-110.0°C, calcium hydroxide decomposition at temperature ranges 439.4-450.7°C and secondary carbonates decomposition at temperature ranges 657.4-669.3°C. We experimentally proved that the rates of dehydration of hydrated Portland cement was significantly influenced by the liquid glass concentration. Optimum liquid glass content was grounded in the protective layer of composite finishing material, modified with low-temperature plasma.

“…High-temperature processes are widely used in various technologies: surface treatment [15,16], processing of powders and waste [17], separation of isotopes [10], obtaining powders of refractory materials [18]. At present, however, insufficient attention is paid to the possibility to control the sizes of dispersed particles of diamagnetic substances formed from the high-temperature state by the constant magnetic field.…”

We studied experimentally the condensation of Zn and Cu vapors from a high-temperature gas in an external weak constant magnetic field. We observed at all applied conditions, a chaotic time shift of the maximum of the size distribution function of dispersed particles. Simultaneously, a decrease in the width of the size distribution function of dispersed Zn particles from 40 nm (0 mT) to 10 nm (44 mT or 76 mT) was observed. The sizes of Zn particles were determined by laser probing. The sizes of dispersed Cu particles, determined by analyzing a substrate sample, were in the range of 10-400 nm without a magnetic field, and the range 30-320 nm in a magnetic field of 30 mT. The authors explain the observed results by arranging the dynamics of the spin pair of unpaired electrons of an atom from the gas phase and of an atom on the surface of a condensed particle in a magnetic field. Therefore, in a magnetic field, when an atom collides with a dispersed particle or condensation nucleus, the probability of creation of a singlet pair of spins of unpaired electrons is higher than that without a field.
