“…A very important factor is the hydrogeological condition of the soil, including its natural moistening, the groundwater level, the level of flood waters, as well as the possible presence of underground rivers, karst voids, etc. Therefore, when assigning one or another method (technology) of stabilization, studies of soil properties should be carried out in an obligatory way [4][5][6].…”

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.

“…The use of gypsum binders, their modifications, industrial gypsum-containing waste, and gypsum-containing mixes of natural origin, is one of the possibilities for increasing the environmental friendliness and energy efficiency of construction processes [1][2][3]. Gypsum is an environmentally friendly material, its dehydration temperature does not exceed 200°C, which definitely reduces the carbon footprint of the production of this material; therefore, products and plaster mixes based on gypsum are widely used in interior finishing systems [4][5][6].…”

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.

The use of gypsum-containing binders significantly expands both the raw material base and the possibilities of application of materials based on them. Clay-gypsum belongs to this group of binders. Clay-gypsum raw material and binder on its basis are local building materials. Binders based on clay gypsum have advantages under the following conditions: the remoteness of deposits of natural gypsum raw materials and the proximity of production from consumers. Clay gypsum is a natural formation of fine-grained crystalline gypsum, evenly mixed with clay or loam. The amount of gypsum varies from 50 to 95%. The aim of the research was the formation of scientific bases for obtaining clay-gypsum binder stabilized by its properties, as well as the development of optimized parameters for the production of this binder. As a result of research, the technological parameters of receiving clay-no-gypsum binder and modes of its thermal processing (firing) are optimized, and also the influence of technologies on the properties of clay-no-gypsum binder, which can be considered an analogue of binder received from natural gypsum raw material, is studied. It is established that at the age of 28 days of hardening, the compressive strength of clay-gypsum binder fired at the temperature of 250 oC reached 8.8–8.6 MPa, which at the accepted level of security allowed to obtain a binder of G-8 grade. The formation of soluble anhydrite did not exceed 1.5%.
