Abstract
Many waste materials such as peanut shell, pose environmental nuisance. In this research, efforts have been made to convert peanut shell into the fabrication of particleboards using gum Arabic as a binder. Mix ratios of 2:1, 2.5:1, 3:1, and 3.5:1 of gum Arabic to the peanut shell by weight of the peanut shell were produced respectively. Twenty four Particleboards (200 X 50 X 12mm) were fabricated and cured for 28 days. Tests on moisture content, water absorption, thickness swelling, modulus of rupture and modulus of elasticity were conducted according to ASTM D 1037-93 procedures. The Results from the tests indicated that the moisture content of the boards with mean values of 7.8% at the time of conducting the test was also below the maximum of 10% specified by ANSI/A208.1-1999 standard. Particleboards produced using gum-arabic-peanut shell ratio of 3.5:1 gave the best results in terms of the lowest mean values of water absorption 43.30%, and thickness swelling 10.72% after four (4) hours of immersion in distilled water. The mean modulus of rupture and modulus of elasticity values are 5.518N/mm2 and 1556.954N/mm2 respectively, the values are above 3.0N/mm2 and 550N/mm2 as the minimum values specified by ANSI/A208.1-1999 respectively. The particleboards produced met the standard for general-purpose boards except for water absorption and thickness swelling characteristics which were above the maximum of 8% and 3% respectively as specified by ANSI/A208.1-1999.therefore it can be considered cost effective and suitable for indoor structural applications, offering a cheaper alternative to conventional boards.
