Influence of Drying on the Atterberg Limit and Grain-Size Distribution of the Ulsan Marine Deposited Clay

울산 해성퇴적 점토의 건조에 따른 연경도와 입도분포의 변화

In this study, the Atterberg limit and grain-size analysis were carried for the purpose of investigating the influence on drying and organic matter of Ulsan marine deposited clay. The results revealed that Atterberg limit was decreased and grain-size distribution was variable on drying. The presence of organic matter also influenced on the physical properties of the soils. The physical properties of marine deposited clay were variable on drying, so that we recommended grain-size analysis and Atterberg limit test were performed under the wet condition of the soils after sampling.
