The study was conducted to assess the properties of cement bonded board made from Areca catechu (betel nut) stem. Fine, coarse and fine-coarse boards were prepared. The ratios of particles weight and cement were 1:2 and 1:3 for each type of board. The laboratory tests for characterization of physical and mechanical properties were carried out for each type of board. In case of physical properties, moisture content, density, water absorption, thickness swelling and linear expansion were evaluated. Modulus of elasticity (MOE) and Modulus of rapture (MOR) were evaluated for mechanical properties. From all the cement bonded boards, the board made with the ratio of 1:3 showed the best performance. Cement bonded particle board made from betel nut may be an alternative raw material for manufacturing cement bonded board.
