In today's rapidly developing technologies and materials, the problem of their use is especially relevant. This is primarily due to the possibility of qualitative import substitution in the domestic industry of materials that have been produced abroad for many decades. The paper proposes a mathematical model for selecting the best technology on the example of samples of ash foam concrete, based on the application of optimality criteria set on finite sets - factors (technical characteristics of objects) and alternatives (materials of different chemical composition and physical purpose). Based on the suggested model, a calculation method has been developed to standardize the materials that are used in geo-ecoprotective technologies in accordance with the technical requirements of the clients. This methodology makes it possible to make decisions about the scale of production and implementation based on monitoring data on the use of technology over a long period of operation. The choice of specific technologies from among the many technologies under consideration usually has long-term consequences on environmental safety and economic efficiency and benefits.

In this article the possibility of using construction waste (including waste of dismantling of buildings) when receiving building ceramics, heat-resistant materials based on liquid glass and materials based on natural hardening cement binder is considered. The purpose of study was development of building materials compositions made with using of secondary crushed stone screening HYPERLINK "https://www.multitran.ru/c/m.exe?t=2400068_1_2&s1=%EE%F2%F1%E5%E2" of dismantling of buildings for various purposes, which would suit all state standards. Also these materials would have some improved physical-mechanical characteristics and would be more eco-friendly. Optimum compositions of materials made with use of building mineral waste and physical-mechanical characteristics of received materials are given. For research of waste structure and synthesizable materials structure X-ray phase, differential-thermal methods of analysis and grain size measurements were used. The geological-ecological evaluation of secondary crushed stone screening use efficiency in developed technologies is given.

“…Foamed concrete, due to its lightness, thermal insulation properties and resistance to collapse, is a popular choice for creating a variety of building structures and products. However, its properties and characteristics can be significantly improved with the use of various additives [ [1], [2], [3], [4], [5]].…”

The article presents part of the results of the study of the components of foam concrete made by the two-stage foam injection method, in particular, the influence of microsilica and post-alcohol bard on the setting time and strength of cement. The paper shows the methodology for determining the compressive and flexural strength, selection of the composition of components, analysis, and evaluation of setting times, and strength characteristics of the compared samples. During the study, laboratory experiments were performed to better understand how these additives affect the behavior of cement mixtures. The studies carried out allow us to determine the influence of the modified additive components on the properties of foamed concrete during the production process. The setting time analysis presented in the study revealed that increasing the concentration of the additive significantly reduced the setting time performance of cement. With increasing the content of microsilica and post-alcohol bard at 10% and 30% of the cement weight, the setting initiation and completion times are significantly reduced. To evaluate the change in strength, samples were made and tested in compression and flexure at ages of 3, 7, 14, 21, and 28 days of normal moisture curing. According to the results, it was found that the additive, by accelerating the curing, promotes strength improvement both at an early age and at the design age (28 days). The experimental results showed that the flexural and compressive strength of the material increased as the concentration of the additive increased. The maximum increase in flexural and compressive strength was recorded at additive concentrations of 10% and 30%. This indicates the important role of additives in the strengthening of materials and their potential application in construction. The additive showed an optimum positive effect, therefore, the use of this percentage of additive is the most effective for increasing the compressive and flexural strength of concrete.
