    Pęcznienie mineralno-chemiczno-organicznych mieszanek gruntowych
    (2007) Stryczek, Stanisław; Gonet, Andrzej; Rzyczniak, Mirosław; Czekaj, Lucyna
    The results of studies of determining liability to swelling of chemically treated mixtures of waste drilling mud with organic and ground admixtures are presented in the paper. The investigations were carried out as a part of a project on methods of drilling waste processing and managing. In the course of the analyses, the following parameters were determined: natural humidity, swelling humidity, swelling indices, degrees of swelling, mineral-chemical--organic ground mixtures. The trends of changes of swelling indices, depending on the composition of the mixtures, were also determined.

    Wpływ temperatury na właściwości technologiczne zaczynów uszczelniających stosowanych do prac geoinżynieryjnych
    (2007) Stryczek, Stanisław; Gonet, Andrzej; Wiśniowski, Rafał
    Sealing slurry should meet a number of requirements resulting from the specific conditions encountered in the injection wells during rock mass sealing and reinforcing operations. Sealing slurries used in the geoengineering works should provide proper course of injection procedures and be resistant to the reservoir conditions. Owing to the atmospheric conditions in which injection is performed (high amplitude of temperature), this factor should be accounted for when working out recipes. The results of investigations of the influence of temperature (5, 10, 20 degrees of Celsius) on the technological properties of sealing slurry based on the metallurgical cement CEM III/B - 32.5 and CEM III/C - 32.5 are presented in the paper.
