Abstract

Abstract

In the context of the "dual-carbon goals" strategy, the use of green and low-carbon geopolymer concrete instead of high-carbon emission Portland cement concrete is currently a hot research topic. This paper focused on fly ash-based geopolymer concrete and conducted a beam test to study the interfacial bonding performance between geopolymer concrete and glass fiber reinforced polymer (GFRP) bas under bending and tensile loads. The influence of different concrete strengths or types on the interfacial bonding performance between geopolymer concrete and GFRP bars was determined. The results showed that due to the difference in mechanical properties between geopolymer concrete and Portland cement concrete, although they showed similar failure modes in the tests with GFRP bars, the failure mechanism at the interface varied with different concrete strengths, and the bonding stiffness and strength also changed accordingly. Finally, the XUE model and Bimodal model were modified for shape factor, and a bond-slip constitutive model suitable for the interface between geopolymer concrete and GFRP bars was established through comparative analysis.
