Abstract
Cement-treated soil is expected of high durability for a long time. However it is reported that cement-treated soil deteriorates due to Ca leaching. In addition, it is confirmed that the influence of Cl- contained in outer environment on Ca leaching from cement-treated soil is large in previous studies. In this study, the numerical prediction method for strength deterioration due to Ca leaching from cement-treated soil considering the influence of Cl- was established. This method consists of ion migration model, Ca adsorption model, carbonation model, Ca leachimg model considering Cl- and strength deterioration model. The validity of the method was verified with comparing the result of exposure test and the prediction result.
