dc.descriptionPreface: The tests reported in parts IIA and III of this report were initiated by Raymond E. Davis at the University of California under contract W 49-129-eng-136, dated 25 April 1949. The Office, Chief of Engineers, by a letter dated 12 April 1950, subject, "Permeability Investigation under Item CW 601, 11 authorized the continuation of these permeability tests at the Waterways Experiment Station. Part IIA includes results of these tests to January 1952. The tests on cores covered by part IIB were conducted at the Waterways Experiment Station in accordance with authority provided in a letter, dated 16 August 1950, from the Office, Chief of Engineers, subject, "Special Concrete Investigation." The appendix to this report was prepared by Roy W. Carlson for the Office, Chief of Engineers. The work by the Waterways Experiment Station was conducted at the Concrete Research Division under the supervision of Herbert K. Cook and Bryant Mather. The tests were performed by or under the direct supervision of E. J. Callan and E. E. McCoy. This report was prepared by Bryant Mather and E. J. Callan. Part IIA is based on a report by Raymond E.
