The behaviour of hybrid fibre-reinforced foam concrete wall panels under axial load
The primary motivation for this in-depth evaluation of the axial performance of fibre-reinforced foam concrete (FRFC) wall panels is to identify the optimal fibre percentage. Standard specimens for assessing the grade and strength, like compressive strength, flexure, and tensile, were used in the experimental programme using eight panels to determine the fibre percentage limit. This research investigates a novel fibre-reinforced foam concrete wall panel comprising two kinds of fibre (steel fibre and polypropylene fibre) and a reinforcement layer. Eight FRFC wall panels were manufactured and axially loaded to study the axial loading behaviour. The fibre fraction was the critical test variable. Careful analysis was conducted on the deflection regarding axial compression, failure mechanisms, and strain correlations. Crushing of foam concrete caused the failure of all panels. The fibre percentage ratio increased the FRFC panels axial load capability by 2.68 times. Among the tested eight wall panels, the FRFC 0.8S0.5P panel was effective in axial load-carrying capacity. When the percentage of polypropylene fibre in panels was held constant at 0.5%, the ultimate axial load increased significantly when the percentage of steel fibre was increased.
