    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete element method; granular materials; particle-scale behaviour; particle degradation; permanent deformation; resilient modulus; rockfill embankment; soil fabric; Diskreta elementmetoden; grusmaterial; verkningssätt på partikelnivå; nedbrytning; permanent deformation; styvhet; stenfylld bank; skelettstruktur; Transport Infrastructure; Transportinfrastruktur;

    Sammanfattning : Unbound granular materials (UGM) are widely used as load-bearing layers and for embankment construction within transport infrastructures. These play a significant role on operation and maintenance of transportation systems. However, pavement and railway engineering still today rely heavily on empirical models based on macroscopic observations. LÄS MER

  4. 3. Cement-Poor Concrete and Grout for Use in Underground Constructions

    Författare :Mohammed Hatem; Leena Korkiala-Tanttu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : This thesis deals with the composition and properties of cement-based materials, concrete and grout, for use as seals and for stabilizing fracture zones in underground facilities like mines and repositories for chemical and radioactive waste. It is of general character with respect to the composition and preparation of concretes and grouts but focuses on the sealing of boreholes for mineral prospection and site investigation for locating underground repositories of hazardous waste.
