| Research Abstract |
Deterioration of lime treated soil appears in soft clayey ground area around tidal rivers. In this study, deterioration mechanism which is caused by salty water infiltration such as tidal river water was investigated. The lime treated soil had been deteriorated by contacting and infiltrating of salty water. Deterioration rate increased with increasing salinity and with decreasing lime content of the treated soil. The reason which causes deterioration was found to be magnesium contained in sea or tidal river water.
