| Abstract |
| Plastic aluminous clays are abundantly available in Tamilnadu.
However, at present the utilization of these clays is very low due
to lack-of detailed characterization. In the present work, the green
and fired characteristics of clays obtained from three different
locations in Tamilnadu (Udayarpalayam, Panruti and Neyveli)
have been investigated to assess their potential use as raw
materials. Physical properties, plasticity index, particle size analysis,
chemical analysis, X-ray diffraction and thermal analysis of
these clays have been carried out. Physical properties such as
density, bending strength, X-.ray diffraction and scanning electron
microscopy of the fired samples have also been carried
ouf. The properties of the above three clays are compared with
each other. The results show that these clays are plastic in nature
co_.,,taining a moderate amount of impurities with high alumina
