ABSTRACT
This paper investigates the effect of lime treatment on the water retention properties of London Clay. A series of contact filter paper tests were performed to obtain the drying Soil Water Retention Curve (SWRC) of statically compacted lime-treated and untreated London Clay specimens respectively. The change in volume with suction during filter paper testing was also determined. In addition to this, further simple tests were performed to assess the shrinkage of samples upon drying. The effect of lime treatment on water retention ability and volumetric change of the tested lime-treated and untreated London Clay soil is shown and discussed. The results showed that lime has a clear favourable effect on the volumetric stability of the soil whereas the effects on water retention properties appear to be less marked.
