Figure 3.15 Relationship between potential gradient and normalized electrokinetically
induced fluid flow, for different silica-clay mineral mixtures. Core No. 1: 94 % silica sand
& 6% montmorillonite clay. Core No. 2: 94% silica sand & 6% illite clay. Core No. 3: 94%
silica sand and 6% kaolinite clay. Core No. 4: 100% 200-mesh silica sand (after Chilingar,
et al., 1970).
