The electrokinetic stabilization (EKS) impact on soft soil (peat)
stability towards its physical, mechanical, and dynamic properties
at Johor state, Peninsular Malaysia
Peat is considered one of the most problematic soils in the construction
industry due to its poor physical, mechanical, and dynamic
properties. It exists in the coastal part of peninsular Malaysia, and
covers almost 8% of the country's land. Therefore, building or road
foundations on peat in the coastal region are deemed a serious threat
to construction engineers. Thus, it's essential to strengthening its
weak properties. This study aims to improve the physical, mechanical,
and dynamic peat properties, including shear strength, maximum
dry density, moisture content, liquid limit, and shear wave velocity.
The soil samples were collected from different locations in Parit
Botak area, Batu Pahat District, Johor state, Peninsular Malaysia. The
electrokinetic stabilization (EKS) method was applied with an operated
electric gradient of 150 V through an aluminum electrode on
anode and cathode for 6 hours. As a result, the change in moisture
content, liquid limit, density, and shear wave velocity has indicated
that post-treatment stability has been improved. It is, therefore, concluded
that the EKS technique is effective and capable of strengthening
the properties of soft soil
