· A linear relationship was seen between the clay kaolin content and static yield stress for the calcined clays with similar particle sizes (D1, F, G, B1-fine). When the particle size was significantly smaller (clay A1) or the composition was significantly different (clay B4 with 24% Gibbsite), the static yield stress deviated from this relationship.

The soils differ in their particle-size distribution. The proposition that such differences contributed to the differences in field behaviour was examined by forming artificial soils, each of which was made up from particles of one of the soils, but redistributed with respect to size in the proportion in which they occurred in one of the other soils.
