Effects of addition of montmollironite on the plasticity of kaolinitic clay, Georgia kaolin, was studied by a uniaxial compression test. It was found that the plasticity of Georgia kaolin was affected by the addition of montmorillonite. From the relation of stress-aspect ratio curve appeared by a uniaxial compression test, the relationship between yield point, which represented a fluidity of the plasticity, and water content was studied. It was suggested that the fluidity was improved when montmorillonite was added in Georgia kaolin. When the forming retention of Georgia kaolin added with montmorillonite was compared with that of Georgia kaolin, the forming retention of Georgia kaolin added with montmorillonite was smaller than that of Georgia kaolin. The relationship between the forming retention and the fluidity of Georgia kaolin added with montmorillonite and Georgia kaolin was investigated. The forming retention of paste added montm-, morillonite in Georgia kaolin was increased when the fluidity value was same. The plasticity of a Georgia kaolin green body added with montmorillonite improved on that of Georgia kaolin green body.
