Durability studies at the Portland Cement Association (PCA) over the years have included both laboratory accelerated tests and field exposure to service conditions in a variety of environments. Laboratory accelerated tests have included: freezing and thawing in water; resistance to application of deicing chemicals during exposure to freezing and thawing; resistance to aggressive chemicals such as sulfates; alkali-aggregate reactions; and corrosion of reinforcing steel. Field exposures have included: full-scale concrete pavements subjected to traffic and exposed to severe weather and deicers; simulated bridge-deck sections in outdoor exposure; concretes in sulfate soils; and concrete piles and other specimens in seawater. Some highlights of these studies are presented.
