Abstract : Glen Canyon Dam, located on the Colorado River in northern Arizona, is a gravity-arch dam containing 5 million cubic yards of concrete. The concrete in the dam proper contains a pozzolanic material as a replacement for a portion of the cement. A preliminary pozzolan investigation, reported in Concrete Laboratory Report No. C-882, evaluated, for coupliance with requirements of Specifications No. DS-5053, pozzolans from 74 sources. Selected pozzolans from these sources that met all specifications requirements together with 12 additional pozzolans from different sources were subjected to tests in concrete. Preliminary laboratory concrete investigation, partially reported in Concrete Laboratory Report No. C-526A, was undertaken to evaluate the individual and/or combined effects of various pozzolans and a single lignin base retarding agent on selected properties, such as compressive strength, elastic properties, and length change, including autogeneous and drying shrinkage and expansion due to prolonged moist curing of Glen Canyon Dam concrete. Reported are the results of this investigation.
