This paper describes on the volume change of Sewage Dredged Soils by using laboratory test and volumetric change test. The tremendous change of Moisture Content occured in the Sewage Dredged Soils during the Elapsed Time. The Unit Weight increases during the normally shrinkage limit void ratio and then the unit weight decrease. A volume of Sewage Dredged Soils according to the moisture content is a difference maximum 2.5 times. And there is the difference 3.5 times according to the change of unit weight. Therefore, the moisture content and unit weight computation are very important for the computation on the volume of Sewage Drdeged Soils.

This paper describes the feasiblity of recycling sewage dredged soils as fine affrefate. This paper describes the feasibility of recycling sewage dredged soils as fine aggregate. The specific gravity of the dredged soils was smaller than that of sand due to the effect of dredged sludge. However, the grain size distribution of the dredged soils is relative well graded, and the results of the heavy metal concentration from the leaching test of the dredged soils was significantly lower than the requirements of the allowable criteria. Therefore, the effect of recycling of dredged soils on environment the as fine aggregate was negligible. Also, the specific gravity of the dredged and washed soils was similar to that of sand, and the dredged and washed soils for the most part showed lower heavy metal leaching characteristics than those of dredged soils, Also, the results of the study for evaluation the recycling feasibility of dredged and washed soils as fine affrefate. The organic impurity content of the dredged and washed soils was lower than the requirements of the Korean industrial Standards, and the mortar compressive strength using the washdredged soils also met those of the Korean industrial Standards. And, the strengths of the dredged and washed soils were over 95% of those of the NaOH-treated samples. Therefore, it is expected that the dredged soils will be able to be an alternative for fine aggregate.

본 연구에서는 석분과 하수준설토에 지반물성시험과 토양환경오염 우려기준에 의거한 오염도 측정을 실시하였다. 실험 결과 하수 준설토는 모래가 $70%{\sim}80%$의 비율의 사질계열의 흙으로써 건축 토목공사의 골재재료로써 가치가 크다는 것이 판명되었다. 석분은 세립분의 함량이 큰 관계로 건설재료로 좋은 품질을 보이지는 않았으나 폐광, 석산에서 석재 채취 후 빈 공간 등을 채우는 용도에 적용시킨다면 재활용이 가능한 것으로 나타났다. 유해물질 함유량은 두 시료 모두 토양오염우려기준에 훨씬 못 미치는 수치로서, 재활용시 토양오염에는 거의 영향이 없는 것으로 나타났다.
