ABSTRACT

The pneumatic flow mixing method has many advantages, such as making beneficial use of dredged soil and subsoil possible, allowing any target stabilized soil strength to be obtained within a short period by controlling the type and amount of binder, and facilitating rapid and large-scale execution. Because of these advantages, the method has been applied to many types of construction and for many improvement purposes, including land reclamation, and backfilling behind quay walls and revetments for the purpose of reducing the earth pressure. For land reclamation applications, the binder factor and target unconfined compressive strength of stabilized soil are of the order of 50 to 70 kg/m3 and 100 to 200 kN/m2, respectively.
