Abstract
The time-dependent settlement of soft soil poses serious maintenance problems to developments along coastal and riverside areas that encounter thick, soft soil deposits. To overcome this problem, therefore, a lightweight material called Air-Trapped Soil (ATS) was developed. ATS was prepared using sand produced at a factory, so its quality is highly stable. To determine the characteristics of the developed ATSs, a series of unconfined compressive and split tensile tests were conducted, and the compressive and tensile strength characteristics of the lightweight ATSs of various combinations of cement-air bubble-sand were determined. In addition, the relationship between the compressive and tensile strengths was determined. This result shows that the mechanical strength characteristics of the ATS significantly depend on the quantity of air bubbles in the ATSs.
