Abstract: Casting concrete segments with fiber reinforced self-compacting concrete (FR-SCC) can ease the production process. The simplest way to produce a concrete element is to prepare a mould, cast the concrete and finish it, without placing any reinforcement bars or vibrating. FR-SCC can combine the benefits of SCC in the fresh state and shows an improved performance in the hardened state due to the addition of fibers. In this paper the effects on the workability when using a relatively new type of synthetic structural fibers are identified and discussed. The research results are based on concrete tests, in which the consistency was tested with a coaxial cylindrical viscometer in terms of yield value, and plastic viscosity, µ. Different mix designs were evaluated by varying different mix components with special respect to variable fiber contents. One emphasis was the variation of silica fume content on cement replacement basis and the investigation of the influence on the workability of such.
