Abstract

In situ 3D imaging experiments were conducted on small split cylinder fracture specimens. Three different materials were considered: a conventional portland cement paste, a fine aggregate mortar, and an ultra high performance concrete. All specimens were scanned using x-ray microtomography, which pro- vided high-resolution 3D images before and after fracture. Quantitative image analysis led to measurements of crack surface area and fragmentation. Results showed that presence of aggregates led to significant frag- mentation, and surface area creation.
