Imagine giving large concrete structures something similar to an ultrasound and getting images so detailed you can see cracks just a tenth of a millimeter long. That level of detail just isn’t possible now. Yet such capability could revolutionize how engineers assess the health of thick reinforced concrete infrastructure like dams and power plants and bridges.
The board of editors of the journal Materials and Structures has picked an article by Ph.D. student Gun Kim as one of its outstanding papers of 2015. The research, which demonstrated a new noninvasive way to measure the carbonation of concrete, will now be available online for free as a result. In a letter to one of Kim’s advisers, Laurence Jacobs, Jason Weiss from Materials and Structures said only 10 papers earn the distinction each year.
