Title:	Richtungsanalyse von Fasern in Betonen auf Basis der Computer-Tomographie
Abstract:	Für die Festbetoneigenschaften von Faserbetonen sind die Fasermenge, Faserorientierung und Faserverteilung ausschlaggebend. Dies macht eine Überwachung dieser Parameter notwendig, sei es zur Qualitätssicherung auf der Baustelle oder im Bereich der Forschung zur Weiterentwicklung solcher Betone. Gegenüber bisher angewendeten Methoden zur Untersuchung dieser Einflussgrößen eröffnet die Computer-Tomographie die Möglichkeit, für Betone mit Fasern und Gelegen aller Art die Faserorientierung und Faserverteilung im gesamten Volumen eines Probekörpers zu betrachten und zu analysieren. Direction Analysis of Fibres in Concrete on Basis of Computed Tomography Decisive factors for the improvement of the hardened concrete characteristics of fibre reinforced concrete are the fibre-volumeratio, fibre-orientation and fibre-distribution. The application of fibre reinforced concrete mixtures requires an appropriate control of these characteristics in the context of quality control at the building site as well as in research work done to improve this kind of concretes. Compared to the methods used up to now, the computed tomography offers the possibility to examine and analyze fibre-orientation and fibre-distribution in the entire volume of a specimen.
