Clay-gypsum binder is the main component for products and plaster coverings used in premises with dry climates. The raw material for producing clay-gypsum binder is sedimentary rock containing gypsum dihydrate and clay in an amount from5 to 30%. In order to expand the range and possibility of using clay-gypsum binder, it is hydrophobized by introducing synthetic resins. The purpose of the research presented in the article is to study the possibilities of increasing the softening coefficient of clay-gypsum binder by introducing thermosetting resins. As a result of the experiment, based on the methods of mathematical planning and statistical processing, a methodology for selecting the composition of the clay-gypsum binder was developed and the optimal content of thehydrophobing agentin the binder was determined.

Soil stabilization and strengthening is a necessary complex of engineering measures and can be carried out by introducing organic or mineral substances into the soil which increases soil viscosity and its mechanical characteristics. Soil modification can also be accompanied by mechanical pressure, as well as temperature influence. Judging by the results of the analysis of the state of the issue, a hypothesis was formulated, according to which an improvement in the operational characteristics of the soil is possible as a result of the use of a stabilizer based on quicklime and an active mineral additive. The object of the study was light sandy loam. The experiment was carried out using mathematical planning methods with subsequent statistical processing of the results. The following are accepted as variable factors: the consumption of quicklime, the consumption of ground slag and the specific surface area of ground slag. The strength of the modified soil at the age 28 of hardening under laboratory conditions and its average density were taken as response functions. It was established that the introduction of quicklime and finely ground slag could significantly improve the operational characteristics of the soil as a result of analytical optimization of the obtained strength and density functions of the modified soil.

One of the most important priorities for all countries with property beyond the Arctic Circle and territories located in permafrost areas is the development of special construction technologies and systems. The required conditions are met by insulation systems based on seamless insulation shells made of polyethylene foam. The study of the strength and performance properties of polyethylene foam and its combinability was carried out according to standard methods and using the methods of experimental design and the analytical processing of the results. The change in material properties at negative temperatures was determined based on the results of climatic tests, followed by an evaluation of creep under load. The evaluation of the effectiveness of the design solutions was carried out using special computer programs. It was found that the performance characteristics of products made of polyethylene foam (rolls, mats) meet the requirements for insulation materials used at temperatures down to −60 °C. The resulting material is moderately combustible, which must be taken into account when developing recommendations for its use in insulation systems. A nomogram has been developed that makes it possible to predict the properties of a material and solve formulation problems. Insulation systems were developed, and a visualisation of the thermal fields of the insulation systems of the external walls and ceilings of a building was carried out.
