Concrete Laboratory Studies Dworshak (Bruce's Eddy) Dam, North Fork, Clearwater River Near Orofino, Idaho. Report 1. Beam Tests

摘要

The U. S. Army Engineer District, Walla Walla, concerned with the design of Dworshak (Bruce's Eddy) Dam, No. Fork, Clearwater River near Orofino, Idaho, desired to obtain test data on laboratory-made concrete beams of large cross section cured in sealed condition to simulate structural environment. Facilities for the manufacture and test of such beams were not available at the U. S. Army Engineer Division Laboratory, North Pacific; therefore, the NPDL requested the U. S. Army Engineer Waterways Experiment Station (WES) to perform the desired tests. Three 2- by 2- by 8-ft nonreinforced beams and nine 6- by 12-in cylindrical specimens were molded and tested using mixture proportions and materials furnished by NPDL.
