Abstract:
Describes a two-phase study undertaken by the U.S. Army Corps of Engineers at the Waterways Experiment Station to evaluate the use of antiwashout admixtures in concrete for underwater repair of stilling basins. The first phase consisted of laboratory evaluation of five antiwashout admixtures using two-point workability apparatus and the washout test. The second phase involved placement of selected mixtures underwater by three different methods.
