Evaluating the Risk of Alkali-Silica Reaction in Wyoming: Continued Evaluation of Field Specimens, Proposed Mitigation Strategies and Improving Existing ASTM Standards

The purpose of this research is to continue to monitor and test existing Alkali-Silica Reaction (ASR) specimens; to evaluate the effectiveness of using fly ash as a mitigation tool; and to evaluate how to improve the American Society for Testing and Materials (ASTM) standards and update where necessary. This proposed study builds on a comprehensive test program of a suite of eight (8) aggregate types from pits around Wyoming, with primary focus in the Big Horn Basin and supplemental sources in Rock Springs and Cheyenne, Wyoming. The second phase of the proposal evaluates the effectiveness of using fly ash as a mitigation tool in new construction. The third phase of the proposal repeats the ASTM C 1293 testing for one inconclusive aggregate as well as considering a more rapid testing method.
