Flexural Behavior of Bamboo Reinforced Concrete Beams Treated with Sikadur 32 F

Résumé

This experimental study investigates the flexural behavior of bamboo-reinforced concrete as a sustainable alternative to steel reinforcement. A series of tests, including compressive strength, ductility, and four-point bending, were conducted to assess the material’s performance. The key parameters analyzed include the load-induced bending behavior, strain distribution, and failure capacity. The measured flexural stress of 37.71 N/mm² demonstrated effective tensile resistance and strong load transfer between bamboo and concrete. The bamboo-reinforced concrete exhibited adequate ductility, with an average displacement of 8.69 mm under load. The strain analysis revealed a conventional stress profile, with compression in the top fibers and tension in the bottom like steel-reinforced beams. The beam comparisons exhibited that increasing the depth improved the stiffness and load capacity but reduced the ductility. Overall, the findings support bamboo as a viable and eco-friendly reinforcement material, particularly where steel is cost-prohibitive. Nonetheless, further research is needed to enhance the bond strength and long-term durability for a broader application.
