Airfield self-consolidating concrete pavements (ASCCP): Mechanical and durability properties

This paper investigates the mechanical, transport properties and freeze/thaw durability of self-consolidating concrete mixtures used in airfield self-consolidating concrete pavement (ASCCP). ASCCP mixtures are made with mineral admixtures that include fly ash, silica fume, slag, metakaolin and air entraining chemical admixture (AEA). The results show that the use of metakaolin as the mineral admixture significantly improved the mechanical properties and durability factor, especially the freeze/thaw visual inspection parameters. The use of AEA produced similar improvements, but a decrease was observed in the mechanical properties. Abrasion resistance and impact strength limits were proposed for this study.
