The article considers the issues of thermochemical treatment of the surface of plant aggregates to ensure strong adhesive interaction with a gypsum matrix in a composite building material. A selection of additives contributing to the improvement of adhesive strength and physical and mechanical properties of gypsum boards was conducted. A comparative analysis of the effect of moisture sorption on the durability of the composite material at the processing of fiber aggregates was also performed.

In the article, based on the results of the physicochemical analysis of the mortar of the brick masonry of the Ismoil Samaniy and Minaret Kalyan mausoleum, it is shown that these mortars are gypsum-lime mortars with organic and mineral addition. Taking this circumstance into account, as a result of further research, modified solutions were obtained for the restoration of the aforementioned architectural monuments.

The article illustrated the geochemical barriers in the soils and the radial double-sided geochemical barriers formed in the irrigated meadow soils of Central Fergana. The migration and accumulation of chemical elements and substances in these barriers are illuminated on the basis of geochemical spectral formulas.
And also, the effect of geochemical barriers on the yield of agricultural crops (cotton) was studied.
