Abstract. Kaolin has been widely used both in fundamental studies of soil behavior and in physical model tests. However, the properties of pure kaolin are somewhat atypical of natural clay soils. In the first part of this paper we compare the mechanical properties of sedimented kaolin to median trends established from tests on natural clays and argue that …

Adding acetic acid to specific kaolin induces reverse electroosmotic flow (EOF). The experimental results indicate that the pH of the kaolin after experimentation ranged from 3.78 to 10.48, which did not reach the point of zero charge (pHPZC) identified by previous studies as the critical factor causing the reverse EOF. This reverse EOF was attributed to the differential …
