dc.description.abstractThe purpose of this study was to identify potential alkali-aggregate reactivity of local aggregates provided by the Pittsburgh District according to ASTM C1260 and to investigate the effectiveness of a combination of cementitious materials and aggregates from provided mixture designs in suppressing alkali-silica reactivity (ASR) induced expansions according to the ASTM C1567. Three ASTM C1260 tests were performed for each aggregate (Hanson, Georgetown, and Shelly). A total of 48 ASTM C1567 tests were performed from the combination of the four mix designs, four fly ash sources, and three aggregate sources. The limiting criteria for the proposed materials and mix designs was expansions less than 0.08% at 30 days of testing in accordance to the Unified Facilities Guide Specification (UFGS) Division 03 Concrete Section 03 30 00.50. Based on this specification, the tested aggregates are considered potentially reactive with 30-day mortar bar expansions of 0.1970% for Hanson, 0.1683% for Georgetown, and 0.1623% for Shelly. However, all 48 combinations of the ASTM C1567 tests passed the limiting criteria with 30-day expansions less than 0.08%. These results indicate that the constituent project materials in the proposed mix designs can effectively mitigate ASR.en_US
