State-of-the-art, innovative technique for creating beneficial use of fly ash
The above paver recipe is 70% Class F Fly Ash and 30% Shale. These pavers were fired at circa 2000 degrees Fahrenheit, thereby rendering the fly ash totally inert (harmless).
A contractor industry survey conducted during January 2017 stated that the paver industry covering both the US and Canada grew 8.8% in 2016 over 2015.
