Advancing Concrete Durability Research through X-ray Computed Tomography

Radiation technology such as X-ray computed tomography (X-ray CT) is a powerful tool for materials research. Such non-destructive imaging allows us to visualize in three dimensions (3D) the internal structure of without damaging specimen. This paper thus presents our studies on application microfocus CT, synchrotron radiation and integrated microtomography diffraction (CT-XRD) method advance cement concrete CT images coupled with 3D image analyses allow identify measure air voids, pore scale microstructure crack geometry. Image-based computational simulations provide estimate transport parameters diffusion tortuosity water permeability digitized space. With introduction novel experimental techniques, deterioration or changes hydrated systems, example, attributed calcium leaching, freeze-thaw cycles, elevated temperature, steel reinforcement under tension are further elucidated. review then ends speculation future directions durability research via CT.
