Abstract [en]

This study investigated the effect of pretreatment on theproperties of kenaf fibre cement boards. Homogenous fibre cementboards were made from kenaf bast fibres, cement and water. Thefibres were cut into smaller sizes, mixed with cement and water andformed in rectangular moulds. After demoulding, the boards werecured for 28 days. The boards were manufactured at threepretreatment levels which include hot water, 3% CaCl2, hot water and 3% CaCl2 and a control. The fibre cement boards were tested forModulus of Rupture (MOR), Modulus of Elasticity (MOE), InternalBonding (IB), Water Absorption (WA), Thickness Swelling (TS) andLinear Expansion (LE). Also nail ability and withdrawal resistance,termite, fungi and fire resistances were also assessed. The resultsshowed that the mean MOR ranged from 1.31 to 8.25 N/mm2; the meanMOE from 78.0 to 1636.3 N/mm2 for all treated boards. Mean waterabsorption ranged from 27.52% to 67.64% and the mean thicknessswelling from 14.51% to 48.01% for all treated boards. Statisticalanalysis showed that the effects of the pretreatments were significanton the properties evaluated (p < 0.05). The study concluded that hotwater combined with CaCl2 treated boards exhibited the bestmechanical and physical properties.
