摘要：

This paper investigates the behavior of basalt fiber-reinforted polymer (BFRP) confinement on geopolymer concrete (GPC) cylinders under axial monotonic compression. Results were compared with glassfiber-reinforced polymer (GFRP) confinement on GPC cylinders. Effects of confinement on failure mode, stress-strain behavior, peak axial compressive stress, and ultimate axial strain of the tested specimens were ascertained and discussed. It was observed that the confinement of BFRP is more effective than the GFRP due to the higher elastic modulus and larger rupture strain of the former. Results were also compared with the existing stress-strain models for FRP confined ordinary portland cement concrete (OPC). It was observed that the existing stress-strain models generally cannot provide accurate predictions of the stress-strain behavior of FRP confined GPC. It was concluded that BFRP confined GPC can be considered as a sustainable alternative to the FRP confined OPC.
