Specimens of stabilized clays were studied in an instrumented oedometer, designed and fabricated in-house at the University of Sheffield. One, artificial clay (i.e. kaolin) and two natural clays (i.e. Malaysian and Swedish soft clays) were stabilized with various quantities of stabilizers and cured for different periods prior to tests. The stabilizers used were either pure ordinary Portland cement (OPC) or lime-cement at 1:1 ratio. The newly developed instrumented oedometer simultaneously measures settlement, lateral stress and shear wave velocity of the stabilized clay specimens. The oedometer was essentially a thin-walled floating ring type, measuring 100 mm in diameter and 90 mm in height. Strain gauges were affixed to the outer wall of the ring to measure radial displacement, and hence lateral stress during tests. The top cap and base were both installed with bender element probes for shear wave velocity measurements. The 1-D compressibility characteristics of the stabilized materials were examined together with shear wave velocity measurements. Finally, relevant correlations between the different parameters measured were established.
