| Summary: | The agro-stone panel is a sustainable building material that is gaining popularity in the construction industry of developing countries where they are commonly used for partition walls in low-cost housing projects. This study investigates the partial replacement of fiberglass with bamboo fiber in agro-stone panels to enhance cost-effectiveness, sustainability, and reduce weight. The panels are made using pumice and bagasse as fillers, magnesium oxide (MgO) and magnesium chloride (MgCl _2 ) as binders, and fiberglass and bamboo fiber as reinforcement. Bamboo fiber is a natural fiber used as reinforcement and was extracted by the mechano-chemical method using basic procedures. Specimens were prepared with varying bamboo fiber contents of 0%, 4%, 8%, and 12%. Tests were conducted at 7 and 28 days to determine the physical and mechanical strength of the specimens. The bulk and dry density of the agrostone were conducted, and the results show the density decreases as the percentage of fiber increases for all composites. The density of bamboo fiber is smaller than that of fiberglass and indicates the light weightiness of the product. The bulk and oven-dry density of all specimens were analyzed, yielding values between 1–1.3 g cm ^−3 , which decrease with increasing percentage of bamboo fiber, indicating a lightweight nature. Moisture content, water absorption of the fiber, water absorption of the specimens, and specific gravity of the specimens had a result of 6.38%, 9%, 18%–20%, and 0.76, respectively. The compressive and flexural strength reached their maximum value at 8% of fiber content replacement and decreased beyond this percentage due to increased water absorption of the bamboo fiber. As a conclusion, bamboo fiber offers a cost-effective alternative to fiberglass in the production of eco-friendly agro-stone panels for low-cost housing. |
