Kh.; Sumskoy, D. A.; Chepenko, A. S. Abstract: The paper presents the results of the study devoted tothe reduction of perlite wastesin size in a vortex jet mill, as well as their reduction features. The bonding compositions were obtained at various ratios of cement and perlitesand wastes in a vortex jet mill at different reduction modes. Peculiarities of reduction processes were studied and technological and physical-mechanical properties of obtained bonding compositions were defined. The electron microscopy made it possible to study microstructures of cement stones received from taggedPortland cement and bonding compositions in a vortex jet mill. It was established that the open pores of cement bonding compositions prepared using perlite aggregates are always filled with new growths at various stages of collective growth. The microstructure of bonding compositions has dense structure due to rationally selectedcontent, use of effective mineral aggregates, i.e. perlite wastes thus creating additional substrates for the formation of an internal microstructure of a composite, mechanochemical activation of raw mix allowing obtaining composites with prescribed properties.

A.; Lesovik, V. S.; Volodchenko, A. N. Abstract: Analysis of data from studies of aluminum silicate binder-based construction composites allowed giving theoretical justification and then experimentally confirming a possibility to control synthesis of new growth to obtain composites with predefined characteristics by means of using shales of incomplete clay synthesis of various genesis. Employing aluminosilicate rocks of incomplete clay synthesis, which contain thermodynamically-unstable compounds make it possible to shift from traditional raw materials to production of composite materials on the basis of natural polyfunctional raw material, thus allowing to accelerate synthesis of new growth, change its morphology, optimize microstructure of binding materials and as a result, to improve performance properties of final products. Improvement of performance properties of silicate materials and reduction of their energy content are provided by producing hydrogarnets and other Al2O3–SiO2 H2O compounds in the binding material under condition of hydrothermal treatment without additional pressure.

A.; Lesovik, V. S.; Volodchenko, A. N. Abstract: These days the use of natural and technogenic raw materials is particularly relevant for the production of efficient construction composites, including the use of nature-like technologies. Successful development of efficient compositions of raw mixes using technogenic and natural raw materials of various genesis is only possible on the basis of in-depth and versatile study of physical, chemical and technological solidification. Thus, the use of nonconventional alumina-silicate raw materials during the production of construction composites provides for theoretical and experimental possibility of shifting from traditional raw materials to the production of composite materials on the basis of nonconventional natural and technogenic raw materials. The study resulted in scientific and theoretical fundamentals of alumina-silicate binding agent design on the basis of technogenic raw materials used to produce non-autoclaved silicate materials. It is suggested to use alumina-silicate rocks of incomplete stage of clay synthesis as an active component of non-autoclaved silicate materials, which structure differs with regard to their thermodynamically-unstable compounds, which, in turn, may result in the production of efficient energy-saving high-hollow silicate materials of a new generation with up to 32 MPa compression strength, F15-25 frost resistance and 1100- 1200 kg/m3 average density.

S.; Pershina, I. L.; Degtyarev, D. A. Abstract: The aim of this work is to formulate the systematic study of the influence the geo-factors on human within the framework of architectural geonics, which assumes the transdisciplinary of the study. The formation of the system-structural approach in the study of a specific architectural space determines the principles and models for constructing a geosynthetic ally specific medium that can positively influence the psycho-emotional and physical state of a person. The concrete, practical orientation of the architectural specific space is aimed at enhancing the functional capabilities of the human body by means of architectural geonics. This article, in essence, is a generalization of theoretical material for the identification of specificity, as a phenomenological feature of architectural space. The published author's works, which are referred to in the course of the presentation material, serve as bifurcation representations, suggesting the further structuring of scientific research with an attempt to articulate the essence the phenomenon of specificity of the architectural space.
