摘要：
The paper reports an investigation on the bond behavior between steel reinforcement and powder-type self-compacting concrete (SCC). A total of 135 pull-out cubes were cast by using four self-compacting mixes (SCC) and two vibrated concretes (VC). The main analyzed parameters were the concrete compressive strength, the reinforcement bar diameter, the embedded length of bars and cement/limestone ratio. The results showed that the ultimate bond strength can be greater in self-compacting concrete compared to vibrated concrete. At the same load level the bars in SCC tend to present a smaller slip than in VC. Considering the influence of bar diameter and embedded length, it seems that SCC and VC behave in a similar way.
