Abstract:
X-ray nanotomography was explored for investigation of the microstructure of cement paste in various ages, including 1-day and 28-day. 2D and 3D images were obtained for quantitative analysis and morphological reconstruction. The technique also provided a prospect of viewing interfacial transition zone (ITZ), of which the microstructures were simulated and the evolution of components with respect to the distance from the interface was calculated.
