“…Эффективным способом борьбы с водными растениями и отчасти с тростником и другими гидрофитами является строгое соблюдение рекомендуемых правил эксплуатации каналов, предписывающих создание незаиляющих скоростей водного потока в канале. Такой режим его работы позволит обеспечить неблагоприятные гидрологические условия для водных сорняков за счет увеличения мутности и динамичности водного потока, что губительно сказывается на их жизнедеятельности [10][11][12].…”

“…Обращает на себя внимание довольно высокая эффективность смесей производных мочевины с симм-триазинами, вполне сравнимая с результатами применения препарата тордон-101, выделенного ранее в число наиболее эффективных гербицидов. Объясняется это, по-видимому, значительно более слабым передвижением диурона и симм-триазинов по профилю почвы в сравнении с тордоном-101, что обусловило сохранение их значительных гербицидных концентраций в ограниченном слое почвогрунтов в течение длительного периода времени [12][13][14][15].…”

The article discusses the issues of natural examination of the technical condition of facings of inter-farm canals, which are an important element of the irrigation and drainage systems in agriculture. The purpose of the study is to develop a methodology for natural examination of the technical condition of facings, based on the use of modern methods of surveys. The study presents the results of natural examination of the facings of inter-farm canals in the agricultural areas of the region. The study shows that the facings of inter-farm canals are subject to various types of defects, including erosion, landslides, cracks, and deformation. The severity of these defects depends on the characteristics of the soil, the design of the facings, and the hydrological regime of the canals. The authors have developed a set of criteria for assessing the technical condition of facings, taking into account the characteristics of the geological structure of the soil, hydrological conditions, and other factors affecting the stability of the facings.

“…6). The production and testing of such samples is labor-intensive and requires a large amount of materials, in addition, conducting appropriate tests to obtain comparative data on the resistance of polymer concrete to the destructive action of water, frost, aggressive environment on large samples will take too long [12]. Therefore, to obtain comparative data on water resis-tance, corrosion resistance, weather resistance and other properties, we first prepared and tested small polymersoluble samples (3×3×3 cm cubes, 2×2×10 cm beams).…”

“…The ratio of the resin and aggregate amounts to get dense polymer concrete is usually selected in the same way as for cement concrete (the resin should cover the aggregate grains and fill the voids between them). The introduction of nanostructured microfiller into the polymer concrete composition will save expensive resin [12][13][14].…”

Introduction. Research of polymer concrete properties show that it differs favorably from conventional concrete by such indicators as mechanical strength, resistance to aggressive impact of various environments, water resistance, abrasion resistance, water-repellency and frost resistance. Currently, it is possible to obtain polymer concrete with characteristic and chemical properties -specified density, strength, deformability, ductility, and corrosion resistance. Methods and materials. The research is carried out by comparing laboratory tests of polymer concrete based on furfural binder. Furfural has a high reactivity and can form resin compounds with many chemicals. Diphenylamine was added to furfural in different proportions. Benzenesulfonic acid, sulfuric acid and their mixture at a ratio -1:1 by weight were used as hardeners. Crushed sand or ground andesite based on nanostructured microfiller served as aggregate for various compositions of polymer solutions. The polymer concrete strength, chemical resistance, lasting properties, water resistance, abrasion resistance, metal adhesion were tested during the research. Structural changes in properties were studied by the electron microscopic analysis method. Results and discussion. It is established that the diphenylamine solution in furfural, provided that it is solidified by sulfuric acid, benzolsulfoacid or mixture of these acids, is a polymer binder capable to form a high-strength material under normal hardening conditions by acid-resistant aggregates. It is also determined that to prepare resin, the ratio of furfural and diphenylamine should be within 1:0.5-0.3 by weight. The resin containing 1 weight part (w.p.) of furfural and 0.5 weight part of diphenylamine is conventionally named FD-1; containing 1 weight part of furfural and 0.4 weight part of diphenylamine -FD-2 and resin with 0.3 weight part of diphenylamine -FD-3. Conclusion. The introduction of nanostructured microfiller into the polymer concrete composition could save expensive resin. Comparison of the technologies for producing FD resin and polymer concrete, as well as preliminary test data of the studied materials, can determine the possible technical and economic advantages of polymer concrete based on FD resin over the polymer concrete based on FA (furfurolacetone) monomer which is currently used in construction of hydro-engineering structures. Polymer concrete based on FD resin has high strength and exceeds the strength of polymer concrete based on FA monomer by 20-25%.

The development of production and application of polymers depends on the need to solve many problems, such as safety, health and food, communications, climate, etc. Construction can be singled out in the first place - this is a large field where new materials are used, including polymers. It is polymers that give freedom of creativity to architects, designers of building structures and structures. Polymer materials are not only the industry of synthetic polymers, but also a promising branch of the construction industry. The basis of all polymer construction products is a small list of basic, primarily large-tonnage polymers. Among thermoplastic polymers - this is polyvinyl chloride. Epoxy polymers, although they do not belong to large-tonnage polymers, but the breadth of their application in construction is extremely wide, due to their manufacturability and unrivaled adhesion to all building materials. The range of properties of materials made of polyvinyl chloride and epoxy polymers is so wide that they allow satisfying the most diverse functional requirements. The directions developed at the Department of Technology of Building Materials, Products and Structures (TSMIK) to promote polymer products in the construction industry are connected with materials based on these two polymers. The article briefly describes the main achievements of the department staff in the field of modification of polyvinyl chloride and epoxy polymers, reveals the problems and prospects of further research, new possibilities and boundaries of their effective application.
