    Sammanfattning : In order to reduce the net climate impact of concrete production, it is necessary for the industry to undertake several actions. Among these is to include fly ash and slag as supplementary cementitious materials. Accordingly, this project has studied concrete containing low-calcium fly ash or ground-granulated blast-furnace slag. LÄS MER

  4. 3. Mechanisms of salt frost scaling on portland cement-bound materials: studies and hypothesis

    Författare :Sture Lindmark; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deterioration; Durability; Freeze-Thaw; Frost; Salt; Mechanism; Chloride; Diffusion; Adsorption; Building construction; Cement; Concrete; Byggnadsteknik;

    Sammanfattning : A hypothesis regarding the mechanism causing salt frost scaling on Portland cement-bound materials is described. It is assumed that deterioration is due to osmotic micro ice body growth, as has been previously proposed for frost deterioration of moisture-isolated specimens of cement-bound materials. LÄS MER
