Cement Durability Program, Long-Term Field Exposure of Concrete Columns
Fifty-two portland cements were collected from 47 cement mills distributed throughout the United States for the purpose of developing information about the manufacture, composition, and durability of these cements. After an extensive laboratory test program (previously reported), concrete columns were fabricated using these cements, and these columns were exposed at outdoor tidal weathering stations at Treat Island, Maine, and St. Augustine, Florida. Variables in the exposures were exposure location, type of cement, and aggregate type. The outdoor exposures were carried on for periods up to 30 years. Concrete columns made with untreated cements exhibited very low resistance to the tidal freezing and thawing at Treat Island. Concrete columns made with treated cements exhibited good to extraordinary durability. (Author)
