As a result of the comprehensive scientific and experimental work carried out at the International Scientific and Technological Park of the Academy of Sciences of Turkmenistan, a technology for creating a “Hydrophobic composite coating for water and other structures” was developed and patented.
A promising direction, implemented in the project under the supervision of candidate of technical sciences Meretmukhammet Khudaiberdiev, is the creation of a composite by impregnating a porous synthetic material (PSM) with sulfur-polymer concrete to achieve a synergistic effect by combining fundamentally different materials.
The proposed multi-component coating demonstrates high adhesiveness and strength, providing both external and internal insulation of water structures on a soil base. A significant advantage is the simplification of the waterproofing process due to the lack of need for a combination with traditional concrete, which allows for the coating to be carried out in a non-stationary mode and significantly simplifies the transportation of materials and installation.
Unlike cement concrete with its limited chemical resistance, the new coating containing sulfur has the necessary resistance to aggressive environments. At the same time, the time of strength gain is significantly reduced. Instead of the standard 28 days, the hydrophobic composite coating requires only a few days. High water-repellent properties make it effective in construction on wet soils.
In addition, the material is characterized by rapid hardening (reaching nominal strength from 5-10 minutes to 2-3 hours) and the possibility of recycling.
The concept of creating a composite material based on impregnating a porous synthetic material with sulfur-polymer concrete is a promising direction in the development of modern construction and functional materials that are in demand in various industries due to their combination of lightness, porosity, chemical resistance and rapid hardening.
Further research in this area opens up opportunities for the creation of innovative materials with improved performance characteristics. An important aspect is the industrial use of sulfur formed during the processing of natural gas in the production of new building materials and products.
