Abstract

In this dissertation, a method for measuring water transport and deformation in swelling materials was developed. In the method, the wetting of a sample is monitored by taking X-ray or X-ray tomographic images at suitable intervals. By using various image correction and analysis techniques, the density distributions of solid and
water and the displacement fields as a function of time are obtained as the final results. The most important
application of the method was bentonite, a buffer material used in nuclear waste disposal. The detailed data produced by the method help to model the buffer, and thus to assess the overall safety of the disposal concept.
