Project description

The objectives of this project are to perform a thorough literature review to determine if there are existing test methods that can quantify the performance of chemical PRAs, and if so, what acceptance limits should be used. If the researchers do not find suitable existing test methods, they will provide recommendations for the development and evaluation of new test methods. Candidate test methods will be evaluated based on their ability to measure the performance of uncracked concrete, concrete with autogenously healed cracks, admixed materials, and surface-applied materials. Preference will be given for test methods that can be performed in a short time period (~28 days), are low-cost, and quantify fundamental transport properties.
