ABSTRACT
Lightweight treated soil is a ground material with a density between 0.6 and 1.5 g/cm3 made by mixing sea water, lightener, stabilizing agent, etc. with dredged soil or other source soil. Lightweight treated soil has flowability immediately after it is mixed, but the reaction with the stabilizing agent ultimately produces hardened soil with strength properties equal to or superior to good quality soil material. This chapter describes the properties of the materials used for the mixture, and the characteristics before and after hardening, particularly density, flowability, resistance to separation underwater, permeability, and strength properties.
