摘要

The physical and mechanical properties of cement bonded board produced from Chasmanthera dependens and waste paper was investigated in this study. Boards were produced at 50:50, 60:40 and 70:30 levels of blending proportions of paper-fiber by weight, 800kg/mm3 and 1000kg/m3levels of board density and a constant mixing ration of 4:2 of cement-paper and fiber respectively. The boards were cut into test samples and physical and mechanical tests were carried out. The effect of Blending Proportion and Board Density on Water Absorption (WA), Thickness Swelling (TS), Modulus of Rupture (MOR) and Modulus of Elasticity (MOE) were determined using British standard 373. The mean values for WA ranged from 6.45-14.60%, TS ranged from 0.17-3.71%, MOE ranged from 93.90-946.03Nmm2 while MOR ranged from 0.30-2.02Nmm2. The results showed that increase in board density and blending proportion led to decrease in TS and WA but also resulted in increase in MOE and MOR. The study suggests that Chasmanthera dependens and waste paper are suitable for the manufacture of cement board.
