Concrete Damage-Transport Properties Correlations

Professor Tara Hutchinson

Concrete is by far the most widely-used building material in the United States, with extensive use in the construction of our nation's buildings, highways, tunnels, water supply and sewage systems and other infrastructure. The strong dependency of the service life of concrete on its transport properties means that investigations of the performance of concrete components need to link these transport properties to observed damage states.

In collaboration with Los Alamos National Laboratories and supported by the National Science Foundation, Prof. Hutchinson and other UC San Diego researchers are developing damage-transport property correlations, using an integrated program of structural testing of concrete components, gas permeability testing, and X-ray computed tomography (see 3-D reconstruction).
