| Abstract | ||||
| This study aimed to manufacture particleboards from Casuarina cunninghamiana (C), Eucalyptus camaldulensis (E), and Pinus halepensis (P) trees irrigated with treated wastewater and their mixtures (E-C, E-P, and C-P) with 50%:50% for each individual raw material. Two urea formaldehyde resin levels (9% and 13%) were used. Modulus of rupture (MOR), modulus of elasticity (MOE), and internal bond strength (IB) as mechanical properties and physical properties (water absorption and thickness swelling) were determined. The C-P panels with 9% and 13% resin levels showed the best mechanical and water resistant performance. All the 13% panels satisfy the minimum requirement of the European standard for the MOE, MOR, and IB except for the MOE of (P) panels, which was very close to the recommended value. The mixtures improved the water absorption and thickness swelling compared with the other produced panels especially for the 13% resin content panels. The (E-C) with 9% resin content showed the lowest mechanical properties and water resistance values. The three furnish types and their mixtures showed its suitability for particleboard production using the board processing conditions specified in this study. | ||||
