dc.descriptionAbstract: This is the first of two reports documenting the findings of the Red River Waterway Thermal Study. It includes the selection and characterization of the concrete materials in support of thermal- and incremental-construction analyses. The primary objective was to develop and evaluate materials and construction methods which would yield safe, serviceable structures with lower life-cycle costs. Materials (Type II portland cement, Class C fly ash , and aggregates) were selected based upon materials likely to be used in the construction of Locks and Dams 4 and 5. These materials were characterized and used to develop 15 trial concrete mixtures. Ratios of Class C fly ash to total cementitious materials from 0.25 to 0.60 were studied . Water-cement ratios were varied from 0.45 to 0.65. These mixtures were evaluated based upon strength requirements, economy, and thermal considerations. From the 15 mixtures, 4 candidate mixtures were selected for complete thermal and mechanical properties characterization. Tests included thermal properties, adiabatic ternperature rise, creep, elastic modulus, shrinkage, and compressive strength.-
