STUDY ON THE PROPERTY CHANGES OF LIME-TREATED SOIL UNDER SEA WATER

Abstract

  In order to investigate the influence of seawater on the properties change of lime-treated soil, laboratory experiments were performed. leaching tests, small cone penetration tests and chemical component analyses were conducted by using different concentration of artificial seawater. It was observed that Ca leaching enhanced in the higher concentration of artificial seawater. In the case of cone penetration test, it was found that the cone penetration resistance decreased with increasing concentration of artificial seawater. The depth of decreasing cone penetration resistance was increased with increasing the duration of immersion under artificial sea water. Ca content of lime-treated soil reduces with increasing concentration of seawater. Reduction of Ca content is remarkable at the surface of specimen.
