... This research is conducted to study combined electrokinetic and chemical processes for improving marine sediment. A series of experiments are performed to study the effects of this approach. In the experimental study, the electrokinetic treatment is conducted on a marine sediment mixed with chemical admixtures...

... and soil electrical conductivity. Furthermore the results indicate that the effectiveness of the electrokinetic treatment is directly associated with the electric field intensity surrounding the caisson. This study demonstrates the relationship between the electric field intensity and electro-cementation...

... electrokinetic treatment. It is evidenced that by optimising the electrode arrangement and implementing the polarity reversal the bearing capacity of the steel plates increased up to 4 times; along with the increase in the soil shear strength up to 3 times after sustained application of a DC voltage of 5.2 V...

... ABSTRACT This study is directed to using electrokinetic processes for strengthening of marine sediments in order to enhance the performance of skirted foundations. In this paper, electro-cementation that occurs during the electrokinetic treatment of a highly saline marine clay is studied...
