Production of Ceiling Board Using Bio Composite Of Ground Nut Shell and Palm Karnel Husk with Starch as Binding Resin

Abstract

This study was carried out to seek process parameter for the production of bio-composite Ceiling Board. This is done with a view to having alternative materials to the conventional ceiling boards that are costly and also pose health risks, reducing the cost of building material by utilizing agro- waste with disposal problems. Eight specific objectives were raised. Eight research questions were formulated to guide the study. The study employed Research and Development (R&D) design. Twenty-four (24) bio composite ceiling board samples were produced in different mixing ratio and tested for their properties. The test result are: Modulus of elasticity 5600N/mm, modulus of rupture 0.49N/m² compressive strength 760KPA, density 385kg/m³, thermal conductivity 0.37kw/mk, resistivity 1.28mk/w, water absorption 35.5% and Fire resistance in accordance with ASTM standards The findings revealed that the mix ratio GNS 0.040kg: PKH 0.060kg: starch 0.030kg satisfied all the parameters that were tasted and therefore has the potentials to be adopted for the production of bio- composite ceiling board. Other mix ratios were deficient in one parameter or the other. Based on the findings, cottage industries that would utilize these agricultural wastes should be built in areas where these wastes are found.
