Abstract:
X-ray computed tomography (XCT) is noninvasive and nondestructive. It produces three-dimensional digital reconstructions of samples, allowing for a comprehensive view of microstructure. The article discusses the use of XCT to examine cementitious materials. Three case studies are provided: characterization of cellular concrete microstructure, quantitative analysis of cement phases, and real-time investigation of an alkali-silica reaction.
