Fibre reinforced ultra-high strength concretes
This paper describes the influence of short steel fibres and a fibre mix of short and long fibres on the mechanical properties of Ultra-High Performance Concrete (UHPC) especially regarding the ductility and the size effect. In this regard the fibre contents changed between 0 Vol%, 1 Vol% and 2 Vol%. The results of numerous tests show the capacity of the investigated concretes with maximum grain sizes of 0.8 mm (Reactive Powder Concrete, RPC) and 5.0 mm (UHPC), represented by the flexural strength and the post crack behaviour. Otherwise the compressive strengths of specimens with different geometries are shown. A specific characterisation of the interfacial transition zone of matrix and fibre was made by means of microscopically inspections.
