| Abstract |
| Physicochemical and mineralogical characteristics of the raw materials, viz., clays, fly ash, sandstone and marble waste were studied with a view to finding out their possible utilization in the manufacture of earthenware wall tiles. The studies included plastic and dry properties, particle size distribution, chemical analyses, XRD, DTA as well as fired (at 1350°C) properties. The results showed that the clays selected were highly plastic in nature and contained predominantly kaolinite mineral associated with illite/muscovite as minor minerals. The study also revealed that fly ash contained a substantial amount of mullite, while marble waste contained calcareous minerals like dolomite, akermanite etc. |
