Much of my research has involved evaluating the field performance of concrete structures in aggressive environments and to correlate this performance with accelerated test methods. To better facilitate this linkage between the field and lab, my research group has been involved in the development and monitoring of various outdoor exposure sites in Texas, as well as in Massachusetts and Hawaii (through FHWA funding related to ASR).
These sites have been instrumental in better understanding the mechanisms of deterioration, evaluating preventive measures, and calibrating accelerated laboratory tests.
Below are four exposure sites that my research group, along with collaborators at the University of New Brunswick (M. Thomas) and Laval University (B. Fournier), have developed in Texas since 2000. These sites focus on: ASR, DEF, external (chemical) sulfate attack, physical salt attack, thaumasite form of sulfate attack, carbonation, and corrosion of reinforcing steel in concrete in a marine environment.
If you are interested in learning more about these sites or in testing materials or technologies, feel free to contact me at [email protected].
