One-Dimensional Compression Tests on Stabilized Clays Incorporating Shear Wave Velocity Measurements

Lab experiments were conducted on stabilized clays to study the relationship between shear wave velocity and one-dimensional compressibility. One artificial clay, kaolin, and 2 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 7 days. Lateral stresses were also measured. Supplementary tests were conducted in standard oedometers, mainly to study the effect of the curing period. In all the tests vertical yield stresses were identified and corresponded to the onset of changes in shear wave velocity, when measured. After yield, constrained moduli can be correlated with shear wave velocity.
