Abstract

Expansive clay soils are soils that swell in the presence of water and shrink when they dry out. The swelling pressure generated can cause serious damage to structures above them. Soil stabilization is needed to improve the properties of expansive soils, whether mechanically or physically. In this study, SikaCim Accelerator was used as a stabilizer, with percentages of 2.5%, .3.0%, and 5.0% from the water content needed to achieve the OMC condition in the Standard Proctor test. The purpose of this study was to determine the physical and mechanical properties of expansive clay and stable soil with curing time of 0, 7, and 14 days. The conclusion of this study was SikaCim Accelerator didn’t give effective result to physical properties, this could be concluded from the results of physical properties testing which didn’t indicate significant changes. Soil classification according to AASHTO remained in the same group, which was A-7-5and Mechanical properties increased CBR and UCS values, in contrast there was a decrease in swelling potential and swelling pressure with optimal values of CBR, UCS, and swelling test obtained with 2.5% SikaCim Accelerator and curing time of 7 days..
