This paper investigates the degradation of basalt fiber reinforced polymer (BFRP) bars used for concrete construction in an alkaline environment. The relationships between tensile strength, elastic modulus, shear strength and moisture absorption rate over time are analyzed using a tension test, short-beam test and moisture absorption weighting. The tensile strength degradation of BFRP bars was further compared with that of Glass FRP (GFRP) bars in the literature. The results indicated that BFRP bars exhibit relatively good resistance to alkaline corrosion, maintaining more than 60% of their original strength after 9 weeks at 55 ° C in an alkaline solution. The moisture absorption of BFRP bars conforms to Fick ' s law, which shows that the degradation mechanism is controlled by matrix and related interface degradation. This finding is supported by comparison with the shear strength degradation trend. Compared to GFRP bars under similar alkaline conditions, BFRP bars exhibit a similar degradation rate during the initial phase, but maintain higher tensile strength and strength retention over time.

“…After 90 days, the tensile strength of a glass/epoxy resin composite decreased by 23.81% and the flexural strength by 35.29% (Weib et al, 2011). These values mean that epoxy resin could be safely used for structural design using a conservative security factor of 2 to calculate the reduction in the material's mechanical properties (Garcia-Espinel et al, 2015).…”

“…There are many works reported for basalt fibers with different polymer matrices focusing on the mechanical, tribological and dielectric properties [10][11][12]. Wei et al [13] compared the chemical stability of the basalt and glass fibres composites in seawater solution and reported similar behavior between the both. Colombo et al [14] found that the basalt reinforced epoxy composites had better mechanical strength than the vinylester composite.…”
