Abstract
In this study, in order to investigate the change of pore size distribution with progress of deterioration and consolidation characteristics of the lime-treated clay immersed in seawater, the measurement of pore size distribution by mercury intrusion porosimeter and consolidation test were performed for both deteriorated and non-deteriorated lime-treated clay specimens. The pore size distribution of lime-treated clay immersed in seawater gradually shifts to those of non-treated clay with maintaining total pore volume constant. Furthermore, it was found that the specimen deteriorated in seawater showed large compressibility compared with non-deteriorated specimen. The reason for this phenomenon is not only by disappearing of the cementation in the lime-treated clay due to calcium leaching but also by changing of pore size distribution.
