Abstract
This paper describes the mechanical performance of hybrid fiber concrete with a maximum fiber dosage of 0.75 Vol.%. Two types of fibers were used: short straight steel fibers and long hooked-end steel fibers. The concrete compressive strength (fc,cub150) varied between 55 and 65 MPa, dependent on the fiber mixture. Several dosages of the two types of fibers were examined. Three-point bending tests1 using notched prisms were performed. The obtained results confirm that the flexural strength at small crack widths and the ductility of the hybrid fiber concrete with rather low fiber content is remarkably improved in comparison with plain concrete. Moreover, the postcracking behaviour of the hybrid fiber concrete is not only dependent on the total fiber content but also on the fiber mixture.
