Evaluating the Effectiveness of Fly Ashes to Mitigate ASR and Using Recycled Concrete Aggregate in New Construction

This project shall conduct tests on fly ashes; evaluate moderately reactive, reactive, and very highly reactive aggregates; conduct concrete prism testing; demolish blocks and make recycled concrete aggregate; and continue monitoring field specimens. This project will be conducted in four phases. Phase 1 shall consist of mortar bar and concrete prism tests of moderately and highly reactive aggregates. Phase 2 shall conduct additional concrete prism testing that could permit the Wyoming Department of Transportation (WYDOT) to evaluate specific fly ash sources. In Phase 3 testing on recycled concrete aggregates will be conducted. During Phase 4, the principle investigator will continue to monitor field samples.
