Accelerated water-gain tests were made to determine the effect of various sub-sieve fines (including admixtures) on the capacity of concrete to resist bleeding, or rising of mixing water in the plastic of concrete. During the progress of the program evidence was found which led to the belief that such a test could be adapted to one of the several facets of workability, viz. segregation. The method was found effective in evaluating the quan-tity of sub-sieve fines to use in concrete mixtures.
