Influence of self-compacting concrete fresh properties on bond to reinforcement
Abstract The paper presents a study on the influence of the fresh state behaviour of powder-type self-compacting concrete on the hardened properties when the formwork is filled by pumping from the bottom of the elements. More precisely the possible influence on concrete’s bond to reinforcement is investigated. For this purpose concretes classified in two different slump flow classes have been tested. The influence of the compressive strength was taken into account by using three compressive strength classes of concrete for each slump flow class. Moreover, three bar diameters have been considered. The results showed that the concrete fresh properties have a large influence on bond strength. The influence was observed for the end zone of the elements, and the bond behaviour is also sensitive to bar diameter.
