  1. 1. Chloride Transport in Concrete - Measurement and Prediction

    Författare :Luping Tang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This doctoral work has been carried out to try to classify the basic theories involved in chloride transport in concrete, and at the same time to develop a measurement method and a prediction model for concrete structures submerged in sea water. Chloride binding accompanies almost all the transport processes and has a significant influence on chloride transport. LÄS MER

  3. 2. 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-).
