Concrete is a tension-week building material, reinforcing concrete with steel bars at the tensile zone, its tensile strength can be increased. However, utilizing Mild steel (M.S.) or High Yield Strength Deformed bars (HYSD) bars are costly and not environmentally friendly. There are numerous natural materials, such as fibers, basalt, and bamboo, that can be utilized as steel substitutes. In this investigation, bamboo is employed to replace the conventional steel at tensile zone. Bamboo is ecofriendly and locally available and economically cheap as compared to steel. And also, to control the overall crack growth not limited to the tensile zone Polyvinyl Alcohol (PVA) fiber is also used. Entire experimental study is divided into two phases. First phase of the experimental work is to study the mono PVA fiber reinforced concrete. Fiber dosages varied from 0.0, 0.1, 0.3 and 0.4%. From the results, it is observed that there is no significant improvement in compressive strength with the addition of fibers, but the tensile strength and flexure strength of the concrete increased with the addition of fibers. The second phase of the investigation is to study the flexure behavior of slab panel of 1200 mm × 500 mm × 75 mm with PVA and Bamboo fiber. Based on the findings, it appears that employing bamboo and fiber instead of traditional steel can be a practical option for low-cost housing.
