Mechanical Behavior of Geopolymer Concrete with GFRP Beams- An Experimental Investigation

A recent study has demonstrated the potential of Geopolymer Concrete (GPC) for structural components. In this case, examining the binding behaviour of this reinforced concrete matrix is essential. Data from the literature indicate that when bonding with bending steel bars, GPC performs better than conventional Ordinary Portland Cement (OPC) concrete. Given the limited funding available to state and federal governments for infrastructure maintenance, a new approach to creating more resilient infrastructures is required. On a global scale, Glass Fibre-Reinforced Polymer (GFRP) bars are gaining considerable attention for internal reinforcement in concrete structures. This paper uses experiment analysis to determine the mechanical behaviour of concrete with GFRP-reinforced beams. The proposed work can provide a superior building system with high sustainability, more durability, and suitable strength. Beginning cracking loads, maximum load capacities, load defect behaviour, load-strain curves and failure modes. Utilising ABAQUS, a numerical study of high-strength concrete beams is conducted. The proposed technique carried out the flexural beam test for GFRP, the Pull-out test for GFRP, and the tensile test for GFRP. As a result, this study compares the bond stress of the GFRP bar and HYSD bar; thereby, the proposed technique of GFRP attains lower strength than HYSD.
