“…During the period of anchor installation, aluminum caps were settled at the edge of the anchors in order to close both ends of the steel pipe and ensure the bar placed in the center of the steel pipe. For the purpose of establishing an enough adhesive force between the GFRP bar and the anchor [15,16,21], the galvanized steel pipes were grouted with an epoxy resin of WSR618 (E-51) with the mass ratio (the epoxy resin to the curing agent) of 4:1. After a week, the conditioned GFRP bars were immersed in three prepared solution containers, as shown in Figure 2.…”

Two categories of GFRP specimens, in nominal diameters of 11.2 mm and 15.6 mm respectively, made of E-glass fibers and a vinylester resin were immersed in alkaline solution, saline solution and tap water solution at room temperature. The mechanical and durability properties of tested GFRP bar specimens were determined through direct tensile test and short-beam shear test after exposure to aggressive solutions for different days. The obtained results indicated that for all tested GFRP bar specimens the failure modes of fiber rupture in the tensile test and horizontal cracking in the short-beam shear test would not obviously change with the increasing of exposure period. However, the impact of immersion solutions on the durability degradation of mechanical properties of GFRP bars appeared in the ultimate strength and displacement at failure, and at room temperature the alkaline solution had a greater impact than another two solutions. Under the same exposure conditions, the resistance to the strength degradation of the GFRP bars with a larger diameter was better than that of the smaller GFRP bars. The comparison results indicated that the strength degradation trend of conditioned GFRP bars presented in our study was basically in agreement with the data given in previous studies.

“…As the 262 loading rates adopted in this study was around 8.7 mm/min for all specimens, this parameter 263 cannot be considered a major factor governing the difference between the tensile strength of 264 GFRP bars measured according to the ASTM and CSA standards. Li et al (2015) also found 265 that the loading rate had limited effects on the elastic modulus of GFRP bars as this property 266 is calculated at the linear range of the stress-strain data. This finding was further confirmed in 267 our study, since both the ASTM and CSA test methods returned almost the same modulus 268 values.…”

The fiber reinforced polymer (FRP) bars have become a useful substitute for conventional reinforcement in civil engineering structures for which load capacity and resistance to environmental influences are required. They are often used in concrete structural elements exposed to strong environmental aggression, such as foundations, breakwaters and other seaside structures, road structures and tanks. The basalt fiber-reinforced polymer (BFRP) is the most recently FRP composite, appearing within the last decade. Due to their mechanical properties different from steel bars, such as higher tensile strength and lower Young's modulus, BFRP bars are predestined for use in structures for which the ultimate limit state is rather decisive than serviceability limit state. Experimental tests were carried out to assess the influence of static long-term loads and cyclic freezing/thawing on the behaviour of concrete model beams with non-metallic reinforcement. The bars made of basalt fiber reinforced polymer (BFRP) and hybrid (basalt and carbon) fiber reinforced polymer (HFRP) were used as non-metallic reinforcement. The mechanical properties of both types of bars were also determined.
