Abstract
  • This study involves the study on the properties of clay samples from Pagoh at natural state and stabilized state with Portland cement. The main objective of the study is to identify the unconfined compression strength of original and stabilized clay at different moisture content and curing time. The tests carried out include proctor test, moisture content and unconfined compression test (UCT). Therefore, clay was mixed with Portland cement at a concentration of 10 % by weight of dry soil for the proctor test. The original and stabilized samples were tested in an UCT at different curing period of 14 and 28 days. At the end, the actual result shows that the unconfined compressive strength of the stabilized clay is higher than the original. It is believed that the value of strength is highly affected by the different moisture content and curing time. Therefore, the control of water content and treatment time is essential to produce a strong and safe foundation for any construction purpose. As a result, new stabilization methods to prevent landslides in natural and developed quick clay slopes will be developed. In conclusion, cement stabilization improves the workability of clay.
