Russian manufacturers currently produce screw-threaded reinforcing bars (rebars) and couplers to join them. However, the application of such reinforcement in the construction industry is hindered by a high compliance in screw couplings.</p></sec><sec><title>Aim</title><p>Aim: to assess the compliance of coupling joints reinforced with adhesives.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study used Av500P screw-threaded rebars, couplers, as well as adhesive compounds containing a cement binder and epoxy resin. The compounds were injected into the coupling cavity by means of hand pumps, followed by their natural hardening. The tests were conducted using universal testing machines.</p></sec><sec><title>Results</title><p>Results. In terms of strength, yield, and delaminatability, the compounds were found to meet the required stress-strain properties of couplers. Recommendations for assembling joints are provided.</p></sec><sec><title>Conclusions</title><p>Conclusions. The conducted studies show that Av500P screw-threaded rebars can be joined by means of couplers in construction.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>муфтовые соединения</kwd><kwd>натурные испытания</kwd><kwd>прочностные свойства</kwd><kwd>деформативные свойства</kwd><kwd>технология изготовления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>couplers</kwd><kwd>field tests</kwd><kwd>stress-strain properties</kwd><kwd>manufacturing process</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Финансирование осуществлялось ФАУ «ФЦС».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дьячков В.В., Климов Д.Е., Слышенков С.О.
