Abstract

Wood is an abundant resource of the forest, output and transformed by the wood industry, and joinery. This transformation generates a great quantity of waste which poses a problem of pollution of the environment. In order to take into account the management of the wood chips for the environmental protection and to reduce the cost of housing, clay bricks stabilized at 4% of cement blended with wood chips were manufactured. In order to evaluate the impact of chips and sawdust on the mechanical properties of bricks, an experimental study, was made on these bricks according to the various wood contents of various species [mahogany (or khaya ivorensis), kambala (or excelsa will chlorophora) and limba (or terminalia superba)]. A universal press and a centrifugal machine enabled us to make a correlation between the Young modulus and the compressive strength. We evaluated the effect of wood chips on the one hand, and the nature of wood on the other hand on the compressive strength and the Young modulus of bricks. The results obtained show that the incorporation of the shavings decreases the rigidity of bricks; and that the bricks stabilized with cement and blended with the kambala waste are more rigid than those with mahogany and limba waste. We established the relation between the Young modulus and the compressive strength. The results show that the Young modulus decrease with the compressive strength some is the nature of wood.
