Guidelines for Using Hydrated Fly Ash as Flexible Base. If this happens, the fly ash will form undesirable compounds that may decrease the material's durability. Hydrated fly ash has a high water demand. Therefore, sufficient allowance should be made for subsequent wetting during curing and construction.
Class F fly ash sources were eliminated from WisDOT specifications in the 1990s due to high values of loss on ignition (LOI), which led to difficulties in establishing and maintaining a proper entrained air void system in the concrete used in paving applications.
