Effect of alkaline-earth metal cations on stabilization of loessial and clayey soil using alkalizing

摘要

Results of laboratory investigations are presented to understand the effect of alkaline-earth metal cations on the interaction between loessial and clayey soils with natrium hydroxide. It is shown that the admixtures of 2.5 N and 5 N NaOH solutions influence the crystallization of new formations and increase in soil strength. The introduced admixtures decrease the natrum hydroxide concentration twice without changing the strength characteristics of the stabilized soil.
