Status:  Complete
Report Date:  07/28/2010


In response to a request from the Natural Resources Research Institute, Mn/DOT tested four taconite ledges, which may have the potential to be used in concrete, for alkali silica reactivity according to ASTM C 1293, Standard Test Method for Determination of Length of Change Due to Alkali Silica Reaction, and ASTM C 1260, Standard Test Method for Potential Alkali Reactivity of Aggregates. The results of the tests are detailed in this report.
