This is most probably due to changes in the fiber structure that rendered them stiffer and tougher by the creation of high cement-to-cement bonds and cement-wood bonds [11]. The mean water absorption in most of the boards was less than 20% at 2 h, and not more than 29% at 24 h of immersion in water. The corresponding water absorption in the neat cement at 2 and 24 h, respectively, were 10.7 and 15.6%, confirming the assertion that lignocellulosics generally tend to increase the hygroscopicity of CBWCs [12]. The observed water absorption values compare favorably with the reported findings of previous studies [10,13,14]. According to Ashori et al. [4], this could be possible dueto the hydrogenbondingof thewater molecules tothe freehydroxyl groups present in the cellulosic cell wall of woody material and the diffusion of water molecules into the wood–cement interface. Additionally, large number of porous tubular structures present in wood structure can accelerate the penetration of water by thecapillaryaction.Afterthesaturationofcellwall,wateroccupies micro void spaces. As cited by Olorunnisola [1], materials such as wood can be incorporated in cement-bonded composites if the products are to be used for interior applications. However, such composites should be kept under pressure after manufacturing until curing is nearly complete.
