It has become important to explore means of reducing deforestation in our environment by sourcing alternatives for timber in the forest. Bamboo (Bambusa vulgaris) as a type of grass grows abundantly in tropical regions around the world. It is known for its strength and flexibility, which makes it a popular material for construction, furniture, and other uses which are still being explored. This paper evaluated the use of bamboo for the design of ceiling boards based on the physical and mechanical properties of bamboo. The research explored the use of bamboo powder, bamboo fibre, and bamboo sticks which are usually wasted during construction activities. Rock wool was used as a fire-resistance agent, and urea-formaldehyde was used as a binding agent. The bamboo ceiling boards were tested for their physical (water absorption, thickness, swelling, and density) and mechanical (modulus of rupture and modulus of elasticity) properties. The results showed the resulting board has the lowest value of 41.885% and the highest value of 86.37% of water absorption and the highest value of 97.564% and the lowest value of 41.885% of water absorption when immersed in water for 2hrs and 24hrs respectively, the modulus of rupture recorded was 78.915 N/mm2 and highest density value of 0.424kg/m3. It was concluded that bamboo is a suitable material for the production of particle and ceiling boards. |
