Abstract :
Durability, toughness, dimensional stability and resistance to termites attack are problems of materials used in construction. Environmental effect such as weathering also affect the performance of cement-bonded composite materials. This study examined the physical and mechanical properties of cement bonded board produced from Gmelina arborea (Roxb.) strand and sawdust. Three levels of mixing ratios of cement to wood material 1:1, 2:1 and 3:1 and five levels of material blending proportion of strand to sawdust of 100:0, 75:25, 50:50, 25:75 and 0:100 were adopted for the board formulation, Assessment of the water absorption, thickness swelling, and modulus of rupture, modulus of elasticity and accelerated aging were carried out. The boards’ density recorded 800, 900 and 1000 kg/m3. Mean water absorption ranged from 16.88±10.28 % to 56.36 ±11.70 % while thickness swelling ranged from 0.21±0.20 % to 5.43±0.99 %. Accelerated aging for first and second cycle respectively ranged from 17.15±0.65 % to 56.36±11.70 % for water absorption, while thickness swelling ranged from 5 1.15±0.26 % to 6.25±4.68 %. The mean values for the mechanical properties ranged from 1988.35±92.26 to 6526.90±186.06 (N/mm2) for modulus of elasticity (MOE) and 1.03±0.59 to 5.90±3.76 (N/mm2) for modulus of rupture (MOR), The mechanical result after aging test ranged from 1166.51±15.47 to 3115.70±100.97 (N/mm2) for MOE and 0.95±0.12 to 4.81±0.68 (N/mm2) for MOR. The analysis of variance carried out showed that both mixing ratio and material blending proportion had significant effect on the water absorption and modulus of elasticity while only mixing ratio had significant effect on the thickness swelling and modulus of rupture of the board. The board produced has the potential to be used as substitute for solid wood for asbestos tiles, wall panelling etc.
