Abstract
Wood-cement particleboards were produced from Afara ( Terminalia superba) at three cement/wood ratios; 2·3:1, 1·5:1 and 1:1. The nominal densities of the boards were 800, 1000, 1200 and 1400 kg m −3. The modulus of elasticity (MOE) of the boards improved with increase in cement/wood ratio. Both the bending strength (MOR) and board stiffness (MOE) increased linearly with increase in board density. The boards had low values of thickness swelling after 24 h of water immersion. On the basis of bending strength and dimensional stability, the tropical wood-cement boards (produced at 2·3:1 and 1·5:1 cement/wood ratios) are considered suitable for internal construction.
