MICRO-STRUCTURE OF COMPACTED KAOLIN CLAY

The present paper deals with the micro-structure of a Kaolin Clay compacted in accordance with JIS (Japanese Industrial Standard) A 1210. The methods used for investigation are the scanning electron microscopy using samples impregnated with polyethylene glycol, the x-ray diffraction, and the it is recognized that the micro-structure of the compacted Kaolin Clay mainly consists of block structures which are almost independent of the inner particle arrangement and are of the three-dimensional structure. The two-dimensional feature, therefore, varies depending upon the direction and position to be observed. It is also recognized that the parallelism as a soil mass increases more or less according to the molding moisture content as indicated by the results of x-ray analysis, and from the Kozeny-Carman Equation. This change of parallelism may be caused not be the change of each particle arrangement but by flattening and/or deforming of block structures.
