Charah, the largest privately-held coal combustion products management operator in the U.S., and VSHC Holdings LLC, The Woodlands, Texas-based cementitious materials processor, will market fly ash from NRG Limestone, a generating station with upwards of 500,000 tons per year output. Fuel and related changes at the Jewett, Texas, facility will see a switch from Class F to Class C fly ash production in early 2017.
Charah and VHSC’s CV Ash joint venture will offer specification grade material to Southwest region concrete producers. VHSC will continue to use its patented process to produce additional materials used in concrete and construction, including PozzoSlag 1.2, a Class F fly ash-derived binder matching ASTM C989 Standard Specification for Slag Cement for Use in Concrete performance requirements.
