Abstract :
Excessive moisture content in soil due to rain significantly decreases its bearing capacity, for this reason, stabilizers are used to stabilize the soil, however, the production and use of such chemicals generates large quantities of carbon dioxide that has negative impact to the environment. Table salt is one sustainable alternative for cement and lime, as its hygroscopic property helps remove moisture in soil. The study aims to develop a comparative analysis between cement, lime, and salt as soil stabilizers by determining their strength using free swell index and unconfined compressive strength. Results from experiments with fat clay soil show that stabilized soils achieved an ultimate strength at stabilizer amount of 6% of the mass of soil. Salt attained the smallest amount of swelling, while cement gained the highest compressive strength. In addition, results show that as the percentage amount of stabilizer in clayey soil increases, the swelling potential decreases while unconfined compressive strength increases.
