Investigation of the Properties of Roofing Tiles Manufactured from Agricultural Residues

Abstract

The objectives of this research were to study the properties of roofing tiles. The roofing tiles are manufactured from agricultural residues. The agricultural residues in this work are corncob fibre, plam fruit bunch fibre and water hyacinth fibre. Synthetic urea formaldehyde resin adhesive was selected as the binder. The binder was mixed with other contents 20 percentages. Main properties of roofing tiles investigated in this work were physical, mechanical and thermal properties. Consequently, these properties were compared to the properties of commercial roofing tiles. The experimental results revealed that roofing tiles produced manufactured from corncob fibre, plam fruit bunch fibre and water hyacinth fibre properties were density (D) of 361.94 kg/m3 , 420.32 kg/m3 and 581.31 kg/m3 , respectively. The modulus of rupture (MOR) of corncob fibre, plam fruit bunch fibre and water hyacinth fibre, were 1.83 MPa, 1.92 MPa and 1.97 MPa, The modulus of elasticity (MOE) of corncob fibre, plam fruit bunch fibre and water hyacinth fibre, were 182 MPa, 197 MPa and 199 MPa respectively. Thermal conductivity (K) properties of roofing tiles produced manufactured from corncob fibre , plam fruit bunch fibre and water hyacinth fibre were also 0.032 W/m.K, 0.095 W/m.K and 0.098 W/m.K, respectively. Finally, it was found that the properties of roofing tiles constructed in this work are similar to commercial roofing tiles.
