Stabilization of Clayey Soil with Marble Dust Arnab Debnath, Sumon Saha, and Rana Chattaraj Abstract In this study the effectiveness of marble dust to improve the mechanical properties of clayey soil has been studied. Marble has high lime content, which acts as the main factor for soil stabilization. 25–30% marble dust (MD) is generated during marble quarries and stones are cut as a block. In this study marble dust was added in the range of 0–30% to the virgin soil by weight. Various tests like Atterberg’s limits, compaction test, and strength tests were performed on untreated soil as well as on treated soil. The results obtained in case of treated soil were compared with the results obtained from the untreated soil. Unconfined compressive strength (UCS) tests were performed at different curing intervals. It was found that the soil strength increased with the increase in marble powder content and curing periods. Keywords Marble dust · Clayey soil · Soil stabilization · Compaction · Curing and UCS 1 Introduction Owing to the presence of montmorillonite mineral in clayey type of soil, it swells with addition of water and shrinks with evaporation of water. If any structure is constructed on this type of soil, a lot of damage may be induced to the structure due to the swelling and shrinkage of the underneath soil. This is why these types of soils need to be stabilized. There are several techniques to improve the clayey soil such as by adding different types of additives like marble dust, fly ash, rice husk, cement, and so on. In this study, MD has been used to stabilize the soil. The MD is generated when marble blocks are cut into small pieces. Marble dust is stored in sedimentation A. Debnath · S. Saha · R.
