Stabilization of organic soil with CSA cement

Abstract

Problematic soils, especially organic soils, are not usually suitable for engineering construction purposes due to their high compressibility. The infrastructures built on organic soil can be easily damaged by causing many problems, such as foundation settlement, cracking in the structure, and corrosion. Therefore, this study aims to investigate the effectiveness of CSA cement for the stabilization purposes of organic soil by conducting comprehensive laboratory work for the improvement of organic soil properties. For this purpose, Unconfined Compressive Strength (UCS) and free swell testing were performed on the stabilized soil specimens cured for 3, 7, and 14 days. Samples were prepared at optimum moisture content using different cement content, 0%, 10%, 15%, and 20%. Overall, the use of CSA as a stabilizer for silty would be useful to achieve sufficient strength and meet the requirements subgrade.
