In recent years, a high-tenacity acrylic fiber for technical applications was developed in West Germany. Test data using these special polyacrylonitrile fibers in mortar and concrete are presented. Within a limited parameter study, the amount and geometry of the fibers and the size of the largest aggregates of the matrix were varied. The produced specimens were tested concerning the flexural and compressive behavior as well as crack development due to shrinkage. To determine the optimal length of fibers, integral pullout tests were conducted. The modulus of rupture found in the experiments was used to show the effect of the fibers in a diagram that relates the size of the "plastic zone" to the critical crack width.
