Abstract

The actual status of an in-situ test program exposing different waste glass samples directly to Boom clay is reviewed. Corrosion test tubes have been retrieved after residences for 5 years at 16°C, 2 years at 90°C, and 5 years at 170°C. The corrosion is interpreted in terms of mass loss, surface analysis by SEM and profiling by EPMA and SIMS. At 16°C, glasses dissolve about 0.02-0.08 μm per year. At higher temperature dissolution is more than two orders of magnitude larger. A good agreement is obtained between the mass losses and the surface analyses. The advantages and limitations of the Belgian in-situ tests are compared with the conclusions of an international expert group.
