Abstract
Roof tile clays are the specific clay species among different clay types in Sri Lanka because of the applicability in the industry of roof tile manufacturing. The analysis of the chemical composition of the roof tile clays that available in the Dankotuwa region in Sri Lanka was the foremost objective of the existing research. There were characterized the representative clay samples using X-ray diffraction (XRD) spectrometer, X-ray fluorescence (XRF) spectrometer, and Fourier transform infrared (FT-IR) spectrophotometer. As the basic outcomes of the existing research, mainly there were found the higher Fe content with other trace elements of Zr, Ba, Ti, and K presence of kaolinite and quartz as usual in most of the clays and the presence of glauconite, muscovite and marcasite as the other minerals. The roof tile clay may be alternatively applicable in the industries of electrical, ceramic, and water treatments because of the active progress of some of composed minerals and functional groups on such applications.
