AB  - Effort to remove natural defects from timber led to the development of particle board industry which made use of saw dust, planer shavings and other relatively homogeneous waste materials produced by the wood industries. This study reports on the production of cement bonded particle board from rice husk which is readily available in large quantities in various areas where rice is grown. The chemical additive used to accelerate the setting of cement board during hydration was aluminium Chloride (AlCl<SUB>3</SUB>) due to its availability and the cement to rice husk mix ratio used were 2:1, 1.75:1, 1.5:1, 1.25:1 and 1:1. High density boards were produced and physical property test such as moisture content, density, water soak and linear expansion were carried out while the mechanical properties tested for were static bending test used to determine both moduli of  rupture  and  elasticity  and  impact  resistance.  The  cost  analysis  revealed  that the production of 600 by 600 mm rice husk particle board costs N145.75 while that of wood shavings was N160:00. It was therefore concluded from this study that durable particle board could be produced by using rice husk to totally replace the conventional wood shavings. Thus, its adoption will further enhance local content development in the construction industry.
