    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Betong; Cement; Beständighet; Tösalt-frost avskalning; Tillsatsmaterial; Masugnsslagg; Flygaska; Concrete; Durability; De-icing salt-frost scaling; Cement based materials; Supplementary cementitious materials SCMs ; Ground granulated blast furnace slag; Low-calcium fly ash;

    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
