STRENGTH PROPERTIES OF CEMENT TREATED COODE ISLAND SILT BY THE SOIL MIXING METHOD

Coode Island Silt (CIS) is one of the youngest formed sedimentary foundations in the Melbourne geological region of the Yarra Delta. Because it is a highly compressible material, CIS imposes geotechnical constraints on the design and performance of infrastructure works. This paper investigates the effectiveness of using soil mixing technology via cement stabilization of CIS by studying the improvement of the strength of treated soils. Tests were carried out in two stages: (1) laboratory based stabilization of CIS; and (2) small scale model mixing. The improvement in terms of strength was assessed using unconfined compressive strength (UCS) test. A small-scaled model mixing was set up to mimic the actual mixing scenario on sites. Although it may not be perfect, it gives an indication on the effectiveness of the cement slurry when combining with the silty clay.
