Abstract

The high rate of demand for forest wood consumption is considered as one of the major factor for the high rate of deforestation as well as degradation impact on the environment which has grave consequent on the global warming. The growing demands for wood-based particleboards have raised serious challenges on the sustainability of raw materials to this sector for some time. However, alternative fibers such as agricultural residues, industrial wastes and non-wood plant fibers could contribute greatly in providing the balance between supply and demand for the production of composite panels like particleboard and fibreboard. This paper provides information on the physical, mechanical, thermal and electrical properties of cement-bonded particleboards produced from industrial and agricultural wastes. Cement-bonded particleboards possess properties such as high moisture resistance and dimensionally stability when subjected to water soaking and may serve as cheap construction material for walls and roofing of houses, high resistance to white-rot and brown-rot fungi and r high resistance to fire. The  increase  in  cement  content  of  the  boards  and  introduction  of  chemical  additives lowers the water absorption and thickness swelling of the boards. Increase  in  cement  content  of  the  boards, pretreatment of lignocellulosic materials and  addition  of  chemical  additives significantly  influence  the  particleboard  density,  internal  bonding strength, modulus of rupture, modulus of elasticity, water absorption capacity and compressive strength of the particleboard. This paper provides information on the physical, mechanical, thermal and electrical properties of cement-bonded particleboards produced from industrial and agricultural wastes.
