Both series were performed as a part of Civil Works Investigation, Item CW 6oo, "General Concrete Research." The first series was authorized by the Office, Chief of Engineers, in a letter dated 20 December 1949, subject, "Field Study of Methods for Determination of Air Content of Plastic Concrete." It was conducted at Clark Hill Dam on the Savannah River, Georgia, under the supervision of Messrs. Walter O. Crawley and Ralph A. Bendinelli of the Waterways Experiment Station, with the cooperation and assistance of Messrs. F. W. Facey, Jr., resident engineer and Ted Neelands, concrete engineer at Clark Hill, personnel of the South Atlantic Division Materials Testing Laboratory, and Messrs.
