Abstract:

An essential part of the construction management services provided on Strontia Springs Dam was the quality control of material, mixture proportions, and production for all concrete placed in the project. The entire quality control concept utilized at Strontia Springs was based on securing predictable concrete performance and batch-to-batch uniformity. Samples of cement, fly ash, aggregates and admixtures were routinely tested to monitor the consistency of these materials. Materials handling and the batching and mixing operations were continuously inspected to assure that all equipment was functioning as intended and concrete was being accurately batched. Routine tests were also made on fresh concrete for slump, air content and temperature. The result of the quality control program was a high quality structure which was built to design requirements with economical concrete mixtures, and an absolute minimum number of concrete placement problems during construction.
