UNTERSUCHUNGEN AN VERSATZ- UND VERSCHLUSSSTOFFEN FUER EIN UNTERTAEGIGES ENDLAGER
The tests carried out by the Institut fuer Tieflagerung Braunschweig into backfilling and sealing materials cover the following areas: filling of large cavities, filling of residual cavities and interstices, and manufacture of chamber and gallery seals. A wide range of materials have been examined for their suitability. The tests have been completed in some cases and are still under way in others, so this document is a progress report and final report. The following groups of materials can be distinguished: 1. Cements and latent hydraulic binders (analyses of fly ashes and blast furnace slags, and material tests on various types of cement; setting behaviour of these materials in the presence of water and salt solutions etc.). 2. Bituminous and synthetic materials (bitumen - water emulsion Colfloor BS and the synthetic resin Webac 400 as sealing materials etc.). 3. Salt spoil and waste salt (laboratory pressure settling test with creep and release phases together with in-situ plate load experiments; examination of potash mine waste to determine its mineral content). 4. Non-saline loose rock (mainly results of the suitability tests for the Konrad mine involving iron ore, argillaceous rock, clay and mixtures of these minerals, etc.).
