セメント安定処理土の一軸圧縮強さに及ぼす配合条件の影響

その他

Cement-treated dredged soil can be used in various structures. Predicting the compressive behavior of cement stabilized soil is of major interest in designing soil stabilization. This paper presents the effects of mix proportion conditions on unconfined compressive strength of cement stabilized soils with a wide range of water to cement weight ratios (W/C ratio) and soil to cement weight ratios (S/C ratio). We found that the extent and rate of unconfined compressive strength development is related to the W/C and S/C ratios. In addition, some empirical correlations, which are simple but very useful in practice, are presented to predict the unconfined compressive strength on the basis of W/C and S/C ratios. These findings permit proper selection of mix proportion conditions for cement stabilized soils.
