Abstract

Laboratory experiments were carried out on stabilized clays to study the relationship between shear wave velocity and one-dimensional compressibility. One artificial clay, kaolin, and two natural clays, from Malaysia and Sweden, were tested. These were stabilized with either Ordinary Portland cement or a 1+1 mix of cement and unslaked lime. A purpose-built oedometer was equipped with bender elements in order to monitor the shear wave velocity during tests on 100-mm diameter, 70-mm high samples cured for a set period of seven days. Lateral stresses were also measured. Supplementary tests were conducted in standard oedometers, mainly to study the effect of the curing period. In all these tests vertical yield stresses were identified and corresponded to the onset of changes in shear wave velocity, when measured. After yield, the constrained moduli could be correlated with shear wave velocity.
