Abstract: Investigations on bond and cracking of self-compacting concrete (SCC) have been carried out by means of pull-out and tension ties tests. The test program was prepared to study the influence of intrinsic parameter to the connection concrete-steel (bar diameter: reinforcement ratio and bar roughness) on anchorage and cracking of SCC, allowing a comparison with the known performances of vibrated concrete (VC). Results show that SCC and VC present identical performances. A difference of only 5% is observed in the average normalised ultimate bond stress, for deformed bar. However, the influence of roughness seems to be different for SCC.
We found also that crack spacing depends mainly on reinforcement ratio and bar roughness but no significant changes due to the use of SCC is observed. The use of SCC has no incidence on the average crack width.
