Abstract

The reduction of the risk of cracking has been evaluated by the reduction of drying shrinkage due to the addition of shrinkage reducing admixtures (SRA) and by the increase of the crack opening resistance due to the addition of fibers. Both technologies have been considered individually and used in combination. It has been noted that the addition of SRA delays the time of cracking and the addition of fiber reduces the crack opening. However, the addition of the shrinkage reducing admixture (SRA) to the fiber-reinforced concrete has led the concrete to a better cracking behavior even when the fiber dosage had been reduced. Finally, the cracking time has been predicted by applying two different theoretical approaches.
