Manufacturing and Characterization of Roof Tiles a Mixture of Tile Waste and Coal Fly Ash

Abstract

The study presented in this manuscript focuses on the manufacturing of roof tiles bearing a mixture of tile waste and coal fly ash. A roof tile sample at a different composition was prepared to attain consistence in quality. The conversion factors were described to be able to convert the laboratory results for firing strength and water absorption into the industrial operating conditions. It was determined that the replacement mixture of the tile waste as well as the Tunçbilek fly ash together with the Muttalip clay as the raw material allowed the manufacturing of good quality roof tiles. Seyitömer fly ash was not suitable for use as secondary raw material due to the presence of tile waste with higher SO3 and CaO contents and lower MgO content. In addition to this, maximum 5 % Tunçbilek fly ash samples in the composition of roof tiles provided favorable physical and mechanical characteristics of the commercial product. Kiremit
