    Sammanfattning : The main purpose of European Rail Traffic Management System (ERTMS) is to remove crossborder barriers and create an interoperable railway network across European countries (Smithet al. 2012). Since its birth, ERTMS has faced several issues regarding interoperability andimplementation. LÄS MER

  5. 20. Material Properties of Bulk Hydrophobic Concrete in a Nordic Environment

    Författare :Patrick Rogers; Johan Silfwerbrand; Tang Luping; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkyl alkoxysilane; capillary suction; chloride ingress; concrete; hydrophobic agents; triacylglycerides; Betongbyggnad; Concrete Structures;

    Sammanfattning : Concrete in its unaltered form allows the mass transfer of fluids into and out of its microstructure. These fluids can contain detrimental solutes which change the chemistry of the cement paste and/or the corrosion properties of the reinforcement bars, most noticeably hydrogen carbonates (HCO3-), oxygen (O2) and chloride ions (Cl-).
