Liquid Limit

The chemistry of the pore water, which is also reflected in the exchangeable cations present within the clay minerals, influences the range of results for the Atterberg limits presented in Table 5.2.The monovalent cations (e.g. Na + and K +) give higher values of liquid and plastic limits whereas the presence of divalent and trivalent cations (e.g. Mg 2+ , Fe 2+ and Al 3+ ) give lower values.
