Effect of Mixing Three Lignocellulosic Materials with Different Cement Ratios on the Properties of Cement Bonded Particleboard

This study investigated the effects of nine different mixtures of three lignocellulosic materials and four ratios of cement to lignocellulosic materials (LCM) (2.5:1, 3:1, 3.5:1 and 4:1) on the properties of cement bonded particleboard. The materials were (sunt) Acacia nilotica saw dust, bagasse and cotton stalks. They were collected from different locations in Sudan. Reasonable panel properties were obtained from the three lignocellulosic materials either pure or mixed using different cement/lignocellulosic materials (C/LCM) ratios (3:1, 3.5:1 and 4: 1). The mean values of water absorption percent (WA %) and the thickness swelling percent (TS %) for both the two hours and 24-hours soaking tests, conform favorably to figures reported in previous studies.The highest bending strength (MOR) and modulus of elasticity (MOE) were attained by100% sunt particles with all cement/lignocellulosic materials ratios.
