Examine comprehensive coverage of durability issues affecting portland cement concrete. Includes transport properties (e.g., diffusion, osmosis, sorption, etc.), alkali-silica reaction, external sulfate attack, delayed ettringite formation, corrosion of reinforcing steel, freezing and thawing, and salt scaling. Explore, for each durability issue, the underlying mechanism are presented, along with methods for preventing such distress in new concrete construction. Three lecture hours a week for one semester. Civil Engineering 393D and 397 (Topic: Concrete Durability) may not both be counted. Prerequisite: Civil Engineering 393 or equivalent full-semester course in concrete materials, and consent of instructor.
