The results of the study of the adhesion strength of fiberglass and metal fittings with concrete with different mechanical characteristics are presented. These characteristics were established after the normal curing of concrete B15-30; B25 concrete samples were subjected to alternating freeze-thawing. Testing of all samples was carried out on the digging of reinforcement at a special stand according to GOST 10060-2012. It is established that fiberglass reinforcement has a smaller amount of adhesion strength compared to steel; with increasing strength of concrete, the value of adhesion strength increases, after cycles of freezing and thawing, its fall slightly, but the amount of deformation increases.

Аннотация: В комплексной системной постановке проана-лизирована проблема строительно-технологической утилиза-ции неорганических техногенных отходов промышленности. Рассмотрены методологические, экологические, технические и инновационные вопросы.Актуальность проблемы. Тема Международной научно-практической конференции «В. И. Вернадский: устойчивое развитие регионов» (г. Там-бов, 7 -9 июня 2016 г.) отвечает современным приоритетам проблемы фор-мирования и обеспечения архитектурными, градостроительными и строи-тельными средствами биосферно-совместимой безопасной и благоприят-ной среды обитания человека и общества [1]. В этой связи обоснованным и актуальным представляется рассмотрение концепции и научных основа-ний строительно-технологической утилизации техногенных отходов [2].Чернышов Евгений Михайлович -доктор технических наук, профессор, академик Российской академии архитектуры и строительных наук, директор образовательного твор-ческого академического центра «Архстройнаука», e-mail: chem@vgasu.vrn.ru; Потамошнева Нина Дмитриевна -кандидат технических наук, старший научный сотрудник, заведующая сектором образовательного творческого академического центра «Архстройнаука», ФГБОУ ВО «Воронежский государственный архитектурно-строительный университет», г.

Today, the requirements to thermal insulation of buildings and structures are increasing. Insulation has become an essential part of regulatory thermal protection of buildings. The analysis of the advantages and drawbacks of the existing insulation systems has shown that the most suitable system is the one with the insulation layer located outside the building. Such system of insulation is based on the use of an additional layer, called finishing or cladding, placed on top of the insulation layer to ensure the protection of buildings against atmospheric agents. The purpose of this study was to develop a material for exterior finish cladding of buildings. We developed a composite timber cladding system in the form of laminated composite material consisting of a substrate (base), a binder and a decorative layer. Manufacturing process comprised four stages. Atmospheric effects were modeled according to the GOST climatic test methods. For the rational use of material resources we calculated the optimal material consumption per unit area for the decorative layer. Durability of cladding depends on the substrate material. Under the effect of atmospheric agent the durability of cladding decreases. Heat and ultraviolet exposure causes decrease in durability of cladding after the completion of resin polymerization, which initially leads to an increase in durability. The impact of aggressive media solutions also results in reduced durability of cladding. Durability of cladding depends on the strength characteristics of the substrate. An operation life of cladding is determined by the difference between the mass of cladding with optimal material consumption per unit area for the decorative layer and the mass of similar cladding with the least possible material consumption per unit area for the decorative layer from an aesthetic perspective. The operational life of the developed cladding is at least 15 years. The cement chipboard-resin compound has low adhesive strength, which leads to the conclusion about the impossibility of using cement chipboard as the substrate for decorative cladding. High humidity deformation limits the use of wood particleboards and MDF as a substrate for cladding. Thus, we recommend using WBP plywood as a substrate for the cladding. The economic rationale is based on the comparison of the following materials used for exterior finishing systems: plywood, facing bricks, porcelain stoneware and vinyl siding.

Epoxy resins are oligomers containing epoxy groups and capable of forming cross-linked polymers under the action of hardeners. Epoxy resins are used in the production of adhesives, plastics, glass and carbon plastics, pouring compounds and plastoconcrete. These materials are widely used in construction, mechanical engineering, aircraft and rocket construction, shipbuilding. To improve the performance of epoxy resins, their chemical or physical modification is used. The paper focuses on physical modification of carbon nanomaterials in order to improve the strength characteristics. Methods for modifying epoxy resins with graphite, carbon nanotubes and graphene are analyzed. It is shown that graphene is the most promising material improving the strength characteristics of epoxy resins.
