Development of High-Performance Concrete Mixtures for Durable Bridge Decks in Montana Using Locally Available Materials 2005

Performing organization: Wiss, Janney, Elstner Associates, Inc Research performed in cooperation with the Montana Department of Transportation and the U.S. Department of Transportation, Federal Highway Administration." Bibliographical references: p. 21 Final report; The Montana Department of Transportation (MDT) is performing research to develop a cost-effective, indigenous highperformance concrete (HPC) for use in bridge deck applications. The investigation was divided into two tasks: 1) identification of the optimum cementitious matrix for the HPC and 2) evaluation of the performance of this matrix in combination with aggregates readily available in Montana. The work focused on the use of binary, ternary, and quaternary blends of portland cement with fly ash (Class C and F), slag, calcined clay, metakaolin, and silica fume, in combination with Yellowstone River and Western Montana aggregate sources. Testing included plastic properties, setting characteristics, air-void system paramet
