Improving Stress-Strain Behavior of Waste Aggregate Concrete Using Affordable Glass Fiber Reinforced Polymer (GFRP) Composites

Several studies have highlighted the potential of crushed brick aggregates in non-structural concrete. This is because offer substandard mechanical properties comparison to natural stone aggregates. Synthetic Fiber Reinforced Polymer (FRP) sheets been known overcome this issue. However, enormous costs associated with synthetic FRPs may limit their use several low-budget applications. study recognizes issue and propose a cost-effective solution form low-cost glass fiber (LC-GFRP) sheets. Two types (i.e., solid-clay hollow-clay aggregates) were used fabricate concrete by replacing 50% Experimental results 32 non-circular specimens reported study. To recycled aggregate (RBAC), strengthened 2, 4, 6 layers LC-GFRP Noticeable improvements ultimate compressive stress corresponding strain observed found correlate positively number It was that 4 imparted significant axial ductility irrespective type inherent strength. existing stress-strain models for confined considered predict strain. Accuracy assessed mean ratio analytical experimental values standard deviations. For predictions, lowest value 1.07 deviation 0.10. none able provide good estimates strains.
