Determining NM Harvested Fly Ash Quality for Deployment in Durable Concrete Mix

This Agreement details services provided under the Research & Climate Bureau project CN R925030. The main objective is to assess the viability of using disposed fly ash from six federally operated coal ash storage sites in New Mexico as a supplementary cementitious material (SCM) in concrete. This includes: Characterization via ASTM C618 and C1897; Evaluation of fresh and hardened concrete properties; Micro-modeling of cement hydration with harvested fly ash; Development of mechanistic models; and Validation testing via ASTM C191, C109, C469, and C456.
