Abstract
Self-Compacting Concrete (SCC) is a highly fluid yet stable concrete that can flow consistently under
its own weight, pass between bars, and fill in formwork without the need of compaction. The application of
SCC effectively resolves the difficulties of concreting in situations with complicated formwork and congested
reinforcements. In this paper, the bond between SCC and steel reinforcement was investigated. The bonding
strengths of reinforcing bars were measured using cubic specimens of SCC and of normal concrete. The SCC
specimens were cast without applying compaction, whereas the specimens of normal concrete were cast by
conventional practice with substantial compaction and vibration. The results showed that SCC specimens
generated higher bond to reinforcing bars than normal concrete specimens and the correlation between bond
strength and compressive strength of NC is more consistent.
