The elimination of vibration for the compaction of concrete during placing through the use of self-compacting concrete leads to substantial advantages related to better homogeneity, enhancement of the working environment and improvement in the productivity by increasing the speed of construction. This could become even more important if conventional steel reinforcement, in the form of bars, were to be replaced by the incorporation of short randomly distributed steel fibers in appropriate applications. Along these lines, the present paper deals with the development and characterization of steel fiber reinforced self-compacting concrete. The resulting concrete is characterized in the fresh state by methods used for self-compacting concrete, such as the slump - flow, V-funnel, L-box and box-filling capacity tests. The results appear promising, showing that the self-compactability can be maintained in concretes with fiber contents of up to 40 kg/m3. The mechanical behavior is consistent with that expected in fiber concretes.3. The mechanical behavior is consistent with that expected in fiber concretes.
