ABSTRACT
ABSTRACT: Self-Compacting Concrete (SCC) appeared to avoid the difficult and onerous work of concrete vibration. It can be defined as a material that is capable to flow inside of a formwork, passing by the reinforcement and filling out the formwork, without the use of any vibration equipments. The main objective of this research was developing a high strength SCC with steel fibers for use in precast connections and also to evaluate the behavior of its bond strength with the steel bars of different diameters. The study considered as fundamental parameters, the steel fibers and the steel bars diameter. According to the results, the incorporation of steel fibers increased the bond strength of SCC giving it a ductile behavior according to the fiber content and fiber length. The development of a HSFRSCC reveal itself ideal for use in precast connections as a filling material, producing a more monolithic behavior for the precast structures.
