Influence on the Flexural Behaviour of High-Volume Fly-Ash-Based Concrete Slab Reinforced with Sustainable Glass-Fibre-Reinforced Polymer Sheets

Concrete structures provided with steel bars may undergo deterioration due to fatigue and corrosion, which leads an increase in repair maintenance costs. An innovative approach eliminating these drawbacks lies the utilisation of glass-fibre-reinforced polymer (GFRP) sheets as reinforcement concrete instead bars. This article relates investigation flexural behaviour ordinary portland cement (OPC) slabs high-volume fly ash (HVFA) reinforced bi-directional GFRP sheets. Slab specimens were cast 60% a replacement for 1 mm-thick sheet 2, 3 4 layers. The was compared that Experiment results such cracking behaviour, failure modes load–deflection, load–strain moment–curvature relationships slab are presented. Subsequently, nonlinear finite-element method (NLFEM) using ANSYS Workbench 2022-R1 carried out experimental results. obtained from numerical correlated showed HVFA better alternative reinforcement, led sustainable construction.
