Environmental exposure of samples was carried out in extremely cold (Yakutsk) and moderate warm marine climates (Gelendzhik). Results of static tension and three point bending tests, as well as dynamic mechanical and thermal mechanical analyses have been presented. Changes in physical-mechanical factors for virgin and exposed samples of basalt reinforced plastic rebars have been specified. Tensile strength and maximum bending moment have been found to increase for 6-13 % and 22-58 %, respectively, relative to the initial rates after exposure to various climatic conditions. Investigation of temperature dependences of GFRP rebars allows us to reveal climate-dependent differences in physical-mechanical properties.. © 2020 The Authors. Published by ELSEVIER B.V.
