PREDICTION OF VOID RATIO-OSMOTIC PRESSURE RELATIONSHIP OF CLAYS

Abstract

The osmotic pressuie or the repulsne pressure due to difference in concentration of ions between clay platelets and the bulk solution is popularly predicted by the use of Gouy—Chapman theory. The existing procedures arc time consuming, difficult and laborious. In this paper a simple, quick and yet an accurate  procedure has been presented to obtain the repulsive pressure at any value of d (half distance betwecn clay platelets) or the void ratio or the vice versa. The results are obtained directly by using the figures and tables presented.
