  2. 2. Development of a Method for Accelerated Ageing of Cementitious Materials Used in Repositories for Nuclear Waste

    Författare :Arezou Babaahmadi; Chalmers University of Technology; []
    Nyckelord :Acceleration; Long-Term Performance; Calcium Leaching; Transport Properties; Cementitious Materials; Diffusion;

    Sammanfattning : The Swedish nuclear fuel and waste management company (SKB), is required to validate the service life prediction of the concrete structures in nuclear waste repositories. Considering the repository being in contact with water , the decalcification process of cementitious materials although being very slow can during the very long operational lifetime of the repository (up to 100000 years), cause the degradation of chemical and mechanical properties of the concrete structures.

  3. 3. Atmospheric corrosion of Mg and MgAl alloys – characterization and mechanisms

    Författare :Mehrdad Shahabi Navid; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; EDX; CO2; XPS; Mg and MgAl alloys; NaCl; Atmospheric corrosion; Characterization; 3D imaging; SEM; BIB; Thin film; FTIR; XRD; Pitting; Interference microscopy; FIB;

    Sammanfattning : The atmospheric corrosion of Mg and MgAl alloys was investigated. Corrosion tests were performed in the laboratory under controlled environment. CP Mg, AM50 and AZ91 samples were exposed at 95% RH and 22°C in the presence and in the absence of 400 ppm CO2 for 24 h to 672 h. The passive film was characterized by means of XPS, FTIR, AES and XRD. LÄS MER
