Abstract n this review, scanning and reconstruction principles of XCT are introduced. The latest progress of XCT application on determination of cement components, tracking of cement hydration process, identification of pore structure and micro-crack, change in microstructure due to ingress of external substances and formation of cracks caused by corrosion of reinforcement are presented. Subsequently, an example of using the most advanced XCT on testing development of pore structure is raised. Finally, existing problems on the application of XCT in testing microstructure development of cementitious materials that need to be solved are recommended.
