The establishment of exposure stations, and the conduct of programs of investigations relative to the durability of concrete exposed to natural weathering have been authorized from time to time by the Office, Chief of Engineers. The initial installation of concrete specimens at an exposure station was made at Treat Island, Maine, in 1936 by the Concrete Laboratory of the Passamaquoddy Tidal PowerProject. In 1939 the Office, Chief of Engineers, authorized the Central Concrete Laboratory, North Atlantic Division, to develop data relative to the durability of concrete exposed to severe weathering. Under this authorization specimens were prepared and installed at exposure stations in Maine, Florida, and New York. In 1946 the Office, Chief of Engineers, directed the Concrete Research Division of the Waterways Experiment Station (successor to the Central Concrete Laboratory) to continue the work in connection with these exposure stations. Results of these various investigations have been reported from time to time. Because many of these reports are out of print, this report includes a summary of all of the investigations, with a more detailed description of those that are continuing. (Author).

The ultimate test of the durability of concrete is its performance under the exposure conditions in which it is to serve. Although laboratory tests yield valuable indications of probable durability, the potential disrupting influences in nature are so numerous and variable that actual field exposures are highly desirable to assess the durability of concrete when exposed to natural weathering. To this end, exposure stations have been provided at several locations in the United States. (Author).

A study of the durability of post-tensioned concrete beams and of the types of end caps used to protect the anchorage systems from deterioration when subjected to severe environmental conditions was conducted. Twenty post-tensioned concrete beams 254 by 406 mm (10 by 16 in.) in cross section and 2.44 m (8 ft) in length were cast, post-tensioned, and placed at the mean tide elevation on the beach at Treat Island off the coast of Eastport, Maine. The beams were subjected to twice daily wetting and drying cycles plus an average of 130 freezing and thawing cycles per winter for a period of 12 to 13 years. During this exposure period, the beams were inspected annually to determine the condition of each end cap or plug, the joint between beam and cap or plug, and the beams themselves. At the end of the exposure period, eight representative beams were returned to the laboratory for autopsy and analysis of the protective caps, the method of joint preparation, and the post-tensioning steel being protected. The results of the durability investigation indicated, among other findings, that the end protective caps attached to the beams by reinforcing bars across the cap/beam joint experienced no cap failures; the epoxy concrete end caps provided the best protection to the end anchorages of all methods tested; and the post-tensioning wires in the beams experienced no structural damage over the exposure period provided they were encased in a flexible metal conduit and protected with portland cement grout.
