Operation Flint Lock, Shot Pile Driver, Project Officers Report-Project 3.5, Grouting and Materials Control
The report describes laboratory tests conducted and field support provided by U. S. Army Engineer Waterways Experiment Station (WES) personnel for Project 3.5, Grouting and Materials Control. The objectives, background, and scope of Project 3.5 are presented in Part I of this report. Part II of the report deals specifically with all of the portland-cement-based backpacking used in the Pile Driver program. Field inspection and consultation were provided for the placing of approximately 19,000 cu yd of neat cellular concrete produced according to four sets of basic mixtures corresponding to 50-, 150-, 300-, and 450-psi average static compressive stresses to 40 percent deformation at 28 days age. This material filled the annuli of 51 liner sections and 28 transition sections. The handling, fabricating, and placing equipment and techniques used in the field and the advantages and problems associated with their use are presented in Part II. One thousand and thirty-five 6-in-diameter by 6-in-long cylinders representing the field samples for the four mixtures placed around the liners and transitions were evaluated in the field at 28 days age. Seven hundred and forty-three companion samples for the same sections were evaluated on or about D-day. The results of these tests were analyzed and are presented along with other pertinent remarks for each of the sections backpacked. Part III of this report presents an evaluation of the rock cores drilled from the Pile Driver site. (Author)
