Název v původním jazyce

Laboratory and in-situ testing of gas permeability and self-healing ability of Czech Ca-Mg bentonite

Popis výsledku v původním jazyce

Bentonite is widely used within construction industry and elsewhere. Due to its very low permeability and high swelling ability the bentonite is used as a sealing barrier in waste sites. Its usage is also envisaged in a deep radioactive waste repository.The waste or the package materials will generate gases within and after the lifetime of these structures; therefore the knowledge of gas migration through the sealing system is essential. The aim of presented research is to experimentally study properties of a Czech Ca-Mg bentonite and thus its suitability for use in construction. Therefore several forms are tested: powder, granules, pellets and their mixtures, or compacted prefabricates. Both in-situ and laboratory experiments are being conducted. Alltypes of these experiments are focused on investigation of bentonite permeability and self-healing ability which are key properties for sealing barriers. The in-situ experiment, situated at the Josef Underground Laboratory, consists of a
