Preface:The main report, issued in October 1951, to which the reports in this volume are appendices, provided information concerning the properties of Alfesil, and made reference to tests of Prepakt specimens to determine their resistance to natural weathering as well as to tests for permeability that were to be made and reported at a future date. Further information is now available on the properties of Alfesil, and additional data on the permeability and resistance to natural weathering of Prepakt concrete have also been obtained. This information is presented in Appendix A. The Memorandum to All Concerned, dated 12 July 1951, Subject: "Prepakt Concrete for Civil Works Projects," which was enclosed with those copies of the main report distributed within the Corps of Engineers stated in paragraph 2 that, when available, field reports on the placement procedure used and data obtained on the use of Prepakt concrete in the reinforced spillway slab at Whittier Narrows Dam and around the scroll cases and speed rings in the Bull Shoals Dam powerhouse would be distributed for general information. These reports have now been prepared and are included herein as Appendix B. The preparation and distribution of these appendices were accomplished by the Waterways Experiment Station in accordance with authority provided by the Office, Chief of Engineers, as a part of Civil Works Investigation Item CW 612.
