Selected properties of waste wig, eggshell and waste paper hybrid composites as potential material for wall partitioning

Waste wig fibers, empty eggshell powder and waste paper were recycled in the development of composite boards as potential sustainable material for wall partitioning. Samples were produced by blending these wastes with cement in the presence of water and cured for 14 and 28 days. The samples produced were examined for density, porosity, thickness swelling, internal bonding strength, modulus of rupture and elasticity in line with standard procedures. From the result obtained, there was reduction in porosity, thickness swelling, while internal bonding strength and modulus of rupture and elasticity were enhanced. An optimum value for modulus of elasticity was attained at 0.96 g/cm3 (3.85 MPa for 14 day curing and 3.5 MPa for 28 day curing), even as internal bonding strength increases with increasing density. It was therefore concluded that recycling of these wastes is effective in the development of sustainable materials for wall partitioning. (c) 2021 Elsevier Ltd. All rights reserved.
