- Recent foundation and rock-excavation works have shown that the gneiss bedrock in the harbour area of Karlshamn is clay-weathered. Swelling clay minerals form part of the weathering products and this has created a number of practical problems, the choice of a suitable foundation pressure to avoid heaving being the most important one. This requires the prediction of a reasonably safe value of the swelling pressure and it is shown that the Yong & Warkentin theory can be used for this purpose, provided that the density of the clay mass is fairly moderate and that the particle orientation is taken into consideration. □ Engineering geology, foundations, settlement, rock excavation, clay-weathered gneiss, weathering, swelling clay, heaving, ground pressure, swelling pressure.

Highly compacted sodium bentonite for isolating rock-deposited radioactive waste products

- Sodium saturated bentonite clay compacted to a high density is a very efficient isolation for preventing radiotoxic nuclides from deeply buried canisters with radioactive wastes from reaching the biosphere. The main function of the bentonite, which is applied in the form of blocks between the rock and the canisters in large boreholes, is to provide a practically impervious barrier. The bentonite blocks take up water and swell so that they completely fill the space between rock and canisters. The swelling potential, which is permanent, makes the bentonite self-sealing. This means that rock joints, which may be opened, are sealed by extruding bentonite.
