STABILIZATION OF HEAVY CLAY WITH POTASSIUM CHLORIDE

Some basic considerations of clay mineralogy suggest that potassium chloride, which is readily available in Israel from the Dead Sea, may significantly improve the engineering properties of heavy clay. This paper describes the results of a laboratory investigation into the effect of potassium chloride on the engineering properties of an Israeli heavy clay. The investigation indicated that the addition of potassium chloride results in a significant decrease in the activity of the clay and apparently in a change in its mineral structure. The overall stabilizing effect appears to be a result of this mineralogical change together with the increase of electrolyte concentration. /Author/TRRL/
