The Effect of Pulverized Oil Bean (Pentaclethra Macrophyllaa Benth.) Stalk Additive on the Thermo Mechanical Properties and Microstructure of 0.6ALDR0.3CMT0.05G0.05OBS Aluminium Dross Composite for Building Ceilings Applications

Advanced material selection provides a favourable ceiling composite for building sectors against the effect of flammability and eco-environmental discomfort. The combustion tendency of combustible materials with building structure is pivotal to the selection of appropriate materials for ceiling application. Thermo physical properties of the developed material were examined using an automated Lee's disc apparatus, copper calorimeter and Ultimate Tensile Tester for compressive test. The structural property of the ceiling material is determined using Scanning Electron Microscope (SEM) fortified with energy dispersive spectroscopy (EDS). The result shows the dispersion of oil bean stalk particle in the matrix resulting in enhanced bond nature of the composite. The developed aluminium dross composite ceiling, 0.6Aldr0.3Cmt0.05G0.05OBS, had thermal conductivity within the range of poor conductor at 0.049Wm-1K -1an appreciable lower thermal diffusivity when compared to polyvinylchloride (PVC) ceilings. This work provides development of building ceiling with exclusive distinct characteristics for overall thermal comfort in buildings.
