Evaluating the Effectiveness of Fly Ashes to Mitigate ASR and Using Recycled Concrete Aggregate as an Aggregate Source

This project will be completed in four phases. Phase one will consist of a series of tests conducted on a minimum of two fly ashes for Knife River, Labarge, and one of the two reactive aggregates in the Big Horn Basin. Phase one will evaluate moderately reactive, reactive, and very highly reactive aggregates. Phase two will focus on the concrete prism testing. The more common three month test will be conducted at the University of Wyoming by retrofitting an existing oven within the Civil Engineering Department. Phase three will include demolishing blocks and making recycled concrete aggregate. Phase four will include continued monitoring of field specimens.
