Abstract
Cement bonded composite boards produced from wastepaper and sawdust at densities of 1000, 1200, 1300, kg/m3 and fibre to cement mix ratios of 2:1, 5:2, 3:1 and 7:2 were investigated. The influence of density and mixing ratio on the water absorption (WA), thickness swelling (TS), modulus of rupture (MOR) and modulus of elasticity (MOE) were also determined. Increase in board density and mixing ratio caused decreased in WA and TS and increase in MOR and MOE. Cement bonded composite board samples produced at high board density and mixing ratio levels between 3:1 and 7:2 exhibits highest properties. The WA, TS, MOR and MOE were significantly affected by the board density and mix ratio. Waste materials are suitable for building construction especially the interior components like ceiling installation, partitioning, cladding and table tops for low income Nigerian.
