Alkali - silica reaction (ASR) is one of the most important deterioration mechanisms in concrete leading to substantial damages. Of structures worldwide. Synchrotron-based micro-X-ray diffraction (micro-XRD was.)Employed to characterize the mineral phases formed in micro-cracks of concrete aggregates as a consequence.Of ASR. This high spatial resolution technique enables to directly gain structural information on ASR products.Formed in a 40-year old motorway bridge damaged due to ASR.Micro-X-ray-fluorescence was applied on thin sections to locate the reaction products formed in veins within.Concrete aggregates. Micro-XRD pattern were collected at selected points of interest along a vein by rotating.The sample. Rietveld refinement determined the structure of the ASR product consisting of a new layered framework similar. To mountainite and rhodesite.It is conceivable that understanding the structure of the ASR product may help developing new technical.Treatments inhibiting ASR.
