Abstract:
The word waste readily brings to mind any unwanted item that has outlived its usefulness and needs to be disposed immediately which might have negative effect on the environment. Agricultural waste such as sawdust, palm kernel shell, rice husk, maize husk, etc are available in large volume but there mode of disposal is causing a great menace to the environment. The use of agricultural waste such as rice husk, maize husk and saw dust can be beneficial in its usage as ceiling board to eliminate the health hazard which asbestos presents. This research work seeks to present process parameter for the production of agro waste composite ceiling board. The specimens were produced and cast into rectangular and squares shapes in different mixing ratio, polyvinyl acetate was used as a binder. A total of twenty-eight (28) specimens were formed and allowed to cure naturally in the laboratory, there average values were reported. The produced ceiling boards were tested for percentage of water absorption, flexural strength, modulus of elasticity, thermal conductivity, and density in accordance with ASTM and British standards. From the obtained results, the water absorption properties ranges from 12.30% to 23.35%, the thermal conductivity ranges from 0.098 to 0.065, the flexural strength ranges from 0.05N/mm2 and 0.1N/mm2 , the density of the composite material exhibited a decreasing trend with increase in saw dust content ranges between 103kg/m3 and 190kg/m3.
