| Abstract: | According to a series of factors influencing properties of expansive andcontractive soils,discriminating expansibility-contractibility of clays needs tobe made by comprehensive using six index marks: lithological features,contents of montmorllonite, the anion surface-to-volume ratio, the anode-exchange amounts, the liquid limit and the free expansibility. |
