Investigation on Mode I Fracture Behavior of Hybrid Fiber-Reinforced Geopolymer Composites

Abstract

Recent reports in the literature have shown that fber-reinforced geopolymer composites (FRGC) made with monofbers exhibit a signifcant enhancement in fracture energy. However, many aspects of the fracture performance of hybrid fberreinforced geopolymer composites (HFRGC) remain largely unexploited, and these are predominant for the structures. For the frst time, the mode I fracture energy of HFRGC is investigated. The mode I behavior was assessed using pre-notched beams in accordance with the RILEM three-point bending test. Five diferent HFRGC mixtures were prepared using three fber types: steel, polypropylene and glass (SF, PF and GF). The parameters of the pre-notched beam in fexure tested in this study were the frst crack and peak load, crack mouth opening displacement at the frst crack load and peak load, equivalent tensile strength, post-peak slope, reinforcing index, residual tensile strength and fracture energy. The results reveal that there is a positive interaction amidst the fbers in geopolymer composites that leads to an enhancement in the mode I fracture energy compared to the reference specimen. This study probes the infuence of novel HFRGC while producing high-quality concrete, which can then be leveraged for sustainable infrastructure and various civil engineering works.
