This paper examines differences that develop over time as a result of laboratory and field curing conditions in the physical properties of monolithic waste samples. During field placement of waste treated using stabilization/solidification, a number of subsamples were taken and cured under laboratory conditions. These samples were evaluated periodically using a battery of laboratory test methods in parallel with samples removed from the landfill by diamond core. The results indicate that, although the field-cured sample was cured under very different conditions, the physical nature of the matrix is similar to samples cured under laboratory conditions, after 2 years.
