The monitoring results were important in assessing the efficiency of<br>the technique towards Batu Pahat marine clay. Two reactors were set up; 1.0 M of calcium chloride (CaCl2) and<br>sodium silicate (Na2SiO3) as the electrolyte and stainless steel plates as the electrodes. EKS technique was<br>continued for 21 days with a constant voltage gradient (50 V/m). This technique was performed in two phases<br>where the alteration of EKS was the combination of stabilizers used. The combinations of stabilizers in phase 1<br>and 2 were CaCl2 – distilled water (DW) and CaCl2 – Na2SiO3, respectively. The technique was monitored using<br>electric current, total inflow and outflow of electrolytes and pH of electrolytes. It showed fluctuated profiles of<br>electric current for both phases, attributed by the introduction of calcium ions from the anode compartment. The<br>inflow and outflow of electrolytes results showed that electromigration and electroosmosis occurred during EKS<br>and it indicated the movement of anion and cation to the opposite direction. The pH of electrolytes kept constant<br>value and balanced by electrolysis process at the cathode. Image of soil fabric for untreated and treated clay were<br>presented where most images shows a flaky particles. The observation of those images indirectly explained the<br>effect of cementation behavior of treated clay.<br><br></p> ER -
