In this study, the waste clays extracted from coal basin were used as a wall tile ingredient instead of the clay materials of the standardized biscuit formulation of the wall tile. XRD data show that waste clay contains major clay minerals such as illite, kaolinite and montmorillonite. It was found that clay-size particles (equal or less than 2μm) distributed between 19.85 and 47%. The green and dry strength of the specimen containing illite and/or montmorillonite were increased 35% compared with the standard biscuit specimen. The fired strength of the samples having alkaline earth oxides has been improved 20%, whereas water absorption reduced 28%. It was also found that the substitution of 5% waste clay in the wall tile biscuit formulation has revealed relatively better physical properties.
