Investigation of the usability of Kozluk (Batman) clays as brick and tile raw materials

Mineralogical, chemical, differential thermal, scanning electro microscope and grain size analyzes of Kozluk clays used in brick tile production were performed. According to these results, brick-tile bodies were produced from clay rich and quartz rich raw materials in sand grain size. In addition to these results, liquid and plasticity limits and plasticity indices of these mixtures were determined separately. Whether these bodies produced from illite and chlorite-rich Kozluk clays conform to the brick standards were determined by measuring the final product properties. In order to compare with Kozluk clays, bodies were produced from raw materials obtained from Diyarbakır-Kabi. Increasing firing shrinkage was measured in these bodies due to smectitic clay content. Therefore, the ratio of quartz rich raw material in sand grains was increased in these bodies and this decreased their strength. Optimum mixtures and bodies conforming to the standards were obtained from illitic-chlorite-rich Kozluk clays and smectitic clays caused problems in the production of brick bodies.
