Mechanical Properties of Steel Fiber Reinforced Self-Compacting Concrete

Öz

In this study, steel fiber reinforced self-compacting concrete (SFR-SCC) specimens were examined by considering the effects of different parameters on the material performance and to promote the use of fiber materials in building industry. Use of steel fibers in SCC is still limited due to lack of required codes and standards in this field. More research is required to understand the effects of steel fibers on mechanical properties of the concrete. For this purpose 5 mixes; control and reinforced with 2 different fiber volumes and two different fiber types; were produced. Compressive strength, splitting tensile strength and 3-point notched bending tests were carried out on these specimens for thoroughly evaluating mechanical performance of steel fiber reinforced self-compacting concretes.
