“…In [53], the mechanical properties of reinforcement with a diameter of 5 and 5.5 mm based on polyester and epoxy binder and unidirectional GF and BF after 3 years of storage in the cold climate of Yakutsk are compared. The methodical approach reviewed in [54] has been applied in measurements of the buckling strength and the buckling modulus. At a temperature of -60 C, these indicators increase by 20%.…”

A review and analysis of changes in mechanical properties of basalt fibers (BF) and basalt composite materials under effects of aggressive environments in reference to foreign and Russian scientific literature has been carried out. The changes in the physical and mechanical properties of the fiberglass (FG) and basalt plastic (BP) have been compared. The analysis shows that BF is a good alternative to fiberglass for elaboration of composite materials for various purposes. In the most aggressive alkaline environments, BP resistance is higher as compared with that of FG. If required, BF resistance to chemically active media could be increased by midifying its composition and applying protective layers and heat treatment of fibers. For extended use of BP as an effective structural material under various climatic conditions, including in the Arctic, long-term tests of 10 or more years are advisable and relevant, with control of changes in their mechanical parameters and an analysis of processes of climatic aging developing in BP.

“…There have been multiple studies on the characterization of GFRP bars in tension [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Given the fact that GFRP reinforcing bars cannot resist the required lateral confining pressure from mechanical grips during the material tests, the test method for GFRP bars needs to be different from the conventional steel bars.…”

The widespread use of glass fibre reinforced polymer (GFRP) bars in reinforced concrete (RC) elements has yet been limited due to the anisotropic and non-homogeneous material behaviour of GFRP. The material characteristics of GFRP bars from different manufacturers vary as a function of several factors. Several standards have developed various procedures to investigate the mechanical characteristics of GFRP bars, but universal methods to test different types and diameters of GFRP bars in tension have not been fully developed. Due to the lack of such a standardized test procedure, there are some doubts and gaps in terms of the behaviour of GFRP bars in tension, which has led to lack of reliable information on their tensile properties. The determination of tensile characteristics of GFRP bars, including the tensile strength, modulus of elasticity, and ultimate strain, according to various test standards, is the main subject of the paper. This paper reports test results for tensile characterization obtained on four types of GFRP bars from four manufacturers with six various diameters. Moreover, the study compares various test procedures according to seven standards to characterize the tensile properties of GFRP bars, to examine the proposed test procedures, and to reveal main differences.

“…In recent years, the addition of steel fiber into mixtures of LWAC has received considerable attention for its higher tensile strength and better toughness comparatively to plain LWAC [4][5][6][7][8]. Fiber-reinforced polymer (FRP) bars are regarded as satisfactory alternatives to steel reinforcement in reinforced concrete (RC) structures due to their corrosion resistance, high strength-to-weight ratio, nonmagnetic, and nonconductive nature [9]. The combination of steel fiber-reinforced lightweight aggregate concrete (SFLC) and FRP is expected to be a promising system due to its prospectively desirable serviceability, high strength-to-weight ratio, and reduced overall lifetime cost [10].…”

Three-dimensional nonlinear finite-element (FE) models using an explicit algorithm were established to simulate the behavior of beams reinforced with glass fiber-reinforced polymer (GFRP) bars cast using lightweight aggregate concrete (LWAC) with and without steel fibers, and the progressive damage model was employed to simulate the rupture of GFRP. The developed FE model was evaluated by test results, and it exhibited good agreement with the test results in terms of moment–deflection response, serviceability performance, ultimate capacity, and failure mode. Influencing factors, including the section height, reinforcement ratio, and span length were discussed according to the established FE model. It was revealed that the reinforcement ratio corresponding to balanced failure was higher than that given by code ACI 440.1R, which confirmed the necessity of the amplification factor of a balanced reinforcement ratio to ensure concrete crushing of the beam. For specimens that failed due to concrete crushing, the increase in fiber-reinforced polymer (FRP) reinforcement ratio did not significantly improve the ultimate capacity, but it did have an obvious effect on the reduction of deflection at service load. Moreover, a greater reinforcement ratio was needed for beams when the span length increased.
