The testing of loaded bentonites in connection with deep repository engineered barrier
Original language description
The Centre of Experimental Geotechnics (CEG) is performing a series of tests which involve subjecting bentonites to a number of procedures which simulate the loading of the buffer under deep repository conditions. Two important factors are being considered: temperature (produced by the still active spent nuclear fuel under real repository conditions) and the impact of the infiltration of water further interacting with the bentonite matrix. These factors are being tested in the CEG's laboratory as well as in-situ at the Josef Underground Laboratory. All the relevant geotechnical parameters (hydraulic conductivity, swelling pressure and liquid limit) are evaluated following the loading of the samples and subsequently compared with values obtained from tests on non-loaded samples. Several different types of Czech bentonites have been tested. The material changes to a limited extent after loading. The most apparent change from the geotechnical point of view concerned the evaluation of liqu
