corresponding load decrements (P kPa) <strong>an</strong>d as obtained for black <strong>clays</strong> in this study are<br />
presented in Appendix (B). A summary <strong>of</strong> results <strong>of</strong> percentage swelling under various<br />
loading for tested samples is given in Table 7.20. The variation <strong>of</strong> percentage swelling (S)<br />
with pressure loads (P) is presented in Fig. (7.34). The variation is generally similar <strong>an</strong>d close<br />
for all tested samples, <strong>an</strong>d this once again reflects on the general homogeneity <strong>of</strong> black <strong>clays</strong>.<br />
