Harvesting
For nearly 50 years, SRMG has concentrated its efforts on providing high-quality fly ash products to the Arizona and southwest U.S. concrete markets.
Most recently, Salt River Project (SRP), owner of the Coronado Generating Station, and SRMG expanded their Coronado fly ash marketing agreement to allow for removal or ‘harvesting’ of fly ash from on-site landfill storage.
This harvesting project involves SRMG’s investment of additional capital dollars in beneficiation equipment to process previously landfilled fly ash, resulting in a long-term high-quality supply of ASTM C618 Class F fly ash.
SRMG’s Coronado Harvesting Project adds 300,000 tons per year to the SRMG fly ash supply network and close the gap on seasonal fly ash shortages in the marketplace.
Blending
SRMG has added advanced blending capabilities in Phoenix and Tucson to increase its supply of Class F fly ash.
In Phoenix, SRMG is blending Class C fly ash with Class F fly ash, resulting in an ASTM C618 Class F fly ash.
In Tucson, SRMG is blending Class N natural pozzolan with Class F fly ash to produce a product known as Tucson Pozzolan which complies with ASTM C618 Class F requirements.
In a market where many are experiencing supply shortages, SRMG continues to provide innovative solutions such as blending and harvesting.
