Electrochemical methods, e.g. potential mapping, provide information whether the steel reinforcement is still passive or depassivation has been initiated. By applying such techniques no information on the type of corrosion, its extent and distribution of corrosion products is available. Particular the corrosion progress is a significant problem. Especially in the case of element corrosion in reinforced concrete structures, the development at the anode can not be separated into corrosion damage causing by element corrosion or self-corrosion. Until now also in laboratory tests it is impossible to collect such information without destroying specimens after electrochemical testing was performed place. To overcome this problem it was tried to study the steel surface within the mortar specimens by X-ray tomography (CT). Within the scope of these investigations it could be shown, that X-ray tomography is suitable to make corrosion pits visible which are embedded in a mortar with a cover thickness of about 35 mm. In this publication the corrosion damage of reinforced steel is documented timedependent by X-ray tomography.

Diese einfache Weisheit ist Motivation für die ständige Weiterentwicklung des Untersuchungsinstrumentariums zur Gefügekennzeichnung von Baustoffen. Nachdem die Gefügeaufklärung insbesondere bei mineralischen Baustoffen bereits integrierter Bestandteil der Baustoffcharakterisierung ist, erhöht insbesondere die zunehmende Spezialisierung und Weiterentwicklung der Asphaltbaustoffe zusammen mit der Forderung nach gebrauchsgerechtem Leistungsnachweis den Bedarf an methodischer Entwicklung bei der Strukturkennzeichnung. Besondere Möglichkeiten zur tiefenaufgelösten und zerstörungsfreien räumlichen Visualisierung des Gefüges, der Ableitung strukturbeschreibender Kennwerte aber auch für eine anschließende Diskretisierung der inneren Struktur mittels finiter Elemente bietet das Verfahren der Computertomographie mit Röntgenstrahlen. Mit Hilfe verschiedener Anwendungen soll auf die Möglichkeiten dieser Methodik aufmerksam gemacht werden.

Stock, T1 - The high-resolution synchrotron-based imaging stations at the BAMline (BESSY) and TopoTomo (ANKA) T2 - Developments in X-Ray Tomography VI (Proceedings of SPIE) N2 - The BAMline at the BESSY light source in Berlin and the TopoTomo beamline at the ANKA synchrotron facility in Karlsruhe (both Germany) operate in the hard X-ray regime (above 6 keV) with similiar photon flux density. For typical imaging applications, a double multilayer monochromator or a filtered white beam is used. In order to optimise the field of view and the resolution of the available indirect pixel detectors, different optical systems have been installed, adapted, respectively, to a large field of view (macroscope) and to high spatial resolution (microscope). They can be combined with different camera systems, ranging from 16-bit dynamic range slow-scan CCDs to fast CMOS cameras. The spatial resolution can be brought substantially beyond the micrometer limit by using a Bragg magnifier. The moderate flux of both beamlines compared to other 3rd generation light sources is compensated by a dedicated scintillator concept. For selected applications, X-ray beam collimation has proven to be a reliable approach to increase the available photon flux density. Absorption contrast, phase contrast, holotomography and refraction-enhanced imaging are used depending on the application. Additionally, at the TopoTomo beamline digital white beam synchrotron topography is performed, using the digital X-ray pixel detectors installed.
