Abstract
- The use of coconut husk sawdust and tomato stem particles at varying blending proportion was examined for the production of particle board. Boards of dimensions 350 mm by 350 mm by 6 mm were produced (coconut husk dust, tomato stem particles) at different blending proportion and addition of additive (CaCl2 at different concentrations). The physical properties (water absorption and thickness swelling) and mechanical properties (modulus of rupture (MOR) and modulus of elasticity (MOE)) were investigated. Thickness swelling and water absorption were investigated at 24 and 48 hours. The results showed that boards exhibited mean values of 0.50% to 4.16% and 2.12% to 7.00% respectively of thickness swelling at 24 hours and 48 hours respectively and 13.6% to 25.2% and 17.6% to 29.1% of water absorption at 24 h and 48 h, respectively. The boards also exhibited means of 1.00 N/mm2 to 5.25 N/mm2 and 339 N/mm2 to 3430 N/mm2 for MOR and MOE respectively. An increase in the tomato particle content caused increase in water absorption and thickness swelling, resulting in the highest water absorption and thickness swelling values. Tomato stem and coconut husk dust can be used to produce cement bonded boards after pre-treatment with hot water and preferably both sieved.
