In February, Megawide Construction’s Research and Development (R&D) Team, in collaboration with Precast and Construction Solutions–Precast Team, conducted a load test at our Precast Taytay Plant in Rizal to evaluate precast elements reinforced with different materials.
The study compared Glass Fiber Reinforced Polymer (GFRP) rebars, steel fibers, and traditional steel rebars across three precast elements: half slabs, exterior walls, and housing walls, resulting in nine test samples. Initial elevations were recorded, after which 50-kg sandbags were applied in increments to simulate design loads. Deflection measurements were taken during and after a 24-hour sustained load period, followed by assessment of elastic recovery upon load removal.
Preliminary results show improved durability and serviceability, with GFRP rebars maintaining structural integrity and steel fibers enhancing crack control.
The R&D Team will continue further testing to validate performance across applications.
