An initial report on the effect of the fiber orientation on the fracture behavior of steel fiber reinforced self-compacting concrete

Abstract

This paper presents a report about work in progress of research on the influence of the fiber orientations on the tensile strength of steel fiber concrete. Different fiber orientations in different parts of a structural element are caused by the casting process. Here, as an example, a small plate was cast of self-compacting concrete containing hooked-end steel fibers. The plate was cut into three beams, which in turn have been subjected to X-ray Computed Tomography scanning to obtain fiber orientations and to three-point bending test, to assess the tensile strength and fracture behaviour.
