3 _ - _- (Revised August 1980) PREFACE The.stablishment of exposure stations, and the conduct of programs of investigation relative to the durability of concrete exposed to natural weathering heve 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 Power Project. 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 (now Concrete Technology Division, Structures Laboratory) of the U. S. Army Engineer Waterways Experiment Station (WES) (successor to the Central Concrete Laboratory) to continue the work in connection with these exposure stations. Further authority is contained in multiple letter of the Office, Chief of Engineers, dated 14 September 1948, subject, "Civil Works Investigations of Office, Chief of Engineers," Item CW-604-Concrete "Continuation of Permanent Exposure Stations." Additional authorizations have been provided since that time for the making and installing of specific specimens at these exposure stations. Installation and testing of specimens at the Florida station was discontinued in November Results of these various investigations have been reported from time to time in the reports listed below. 1.

The report is made up of two volumes: Volume 1 (this volume) summarizes the test results of investigations which are still active, and Volume 2 summarizes the findings of completed investigations. The major part of the work reported herein and the preparation of -W this report constitute part of Civil Works Research Work Unit 31132, "Field Exposure Durability Studies of Concrete." The studies were made by the Concrete Technology Division, Structures Laboratory, Waterways Experiment Station. Personnel actively engaged in the direction and conduct of the work include Ms. K. Mather, Messrs. B. Mather, J. M. Scanlon, B. R. Sullivan, R. V. Tye, Jr., E. E. McCoy, E. C. Roshore, H. T. Thornton, R. E. Black, D. Glass, D. Wilson, and G. S. Harris. Mr. Thornton prepared this distribution. During the preparation of this report COL Edmund H. Lang, CE, was Director of the Waterways Experiment Station, and Mr. J. B.
