Cracking behavior of high performance fiber reinforced mortar in tension and bending
In order to investigate the structural behavior of HPFRM (High Performance Fiber Reinforced Mortar), which has a compressive strength of 100 N/mm2 and more and a high tensile ductility by the addition of short steel fibers, tensile tests and bending tests were performed on HPFRM members with and without reinforcing bars. From the test results, it was observed that an increase of fiber content and a large aspect ratio of the fibers led to multiple cranking, with fine cracks at short distances. Moreover, the fiber orientation, as influenced by casting process, affected both the tensile and the bending response.
