Characterization of distributed damage and self-healing in cementitous materials based on time-dependent 3-D x-ray computed microtomography (Micro-CT)

Concrete cracking is inevitable, and can be the result of one or a combination of factors such as dry shrinkage, thermal contraction, fatigue, and embedded steel corrosion. The presence of cracks leads to further deterioration, service life reduction of concrete infrastructure, and frequent maintenance and repairs. These challenges can be...
