The leading manager and marketer of coal combustion products has acquired the Carbon Burn-Out (CBO) technology of PMI Ash Technologies LLC in Raleigh, N.C. The CBO process brings the quality of fly ash produced at coal-fueled electric generating stations to ASTM C618 grade, and can also be used to cost-effectively convert impounded ash to high quality pozzolan for concrete applications.

Responding to electric power generation market forces affecting cementitious materials availability across the concrete industry, Salt River Materials Group (SRMG) has begun shipping an ASTM C618-grade Class F fly ash from its 19th Avenue Terminal near downtown Phoenix. The material raises the company’s net Class F fly ash output and stems from new blending systems installed as part of an upgrade at the terminal—one of five SRMG powder distribution facilities serving Phoenix market ready mixed and precast concrete producers.
