Fly Ash Flowable Fill Mixes
There are two basic types of flowable fill mixes that contain fly ash: high fly ash content mixes and low fly ash content mixes.
There are no specific requirements for the types of fly ash that may be used in flowable fill mixtures. "Low lime" or Class F fly ash is well suited for use in high fly ash content mixes, but can also be used in low fly ash content mixes. "High lime" or Class C fly ash, because it is usually self-cementing, is almost always used only in low fly ash content flowable fill mixes. There is also a flowable fill product in which both Class F and Class C fly ash are used in varying mix proportions.

Famous quotes containing the words fly, ash and/or fill:
“Ye elves of hills, brooks, standing lakes, and groves,
And ye that on the sands with printless foot
Do chase the ebbing Neptune, and do fly him
When he comes back; you demi-puppets that
By moonshine do the green sour ringlets make,
Whereof the ewe not bites; and you whose pastime
Is to make midnight mushrooms,”
—William Shakespeare (1564–1616)
“And in the next instant, immediately behind them, Victor saw his former wife.
At once he lowered his gaze, automatically tapping his cigarette to dislodge the ash that had not yet had time to form. From somewhere low down his heart rose like a fist to deliver an uppercut, drew back, struck again, then went into a fast disorderly throb, contradicting the music and drowning it.”
—Vladimir Nabokov (1899–1977)
“Here come real stars to fill the upper skies,
And here on earth come emulating flies....”
—Robert Frost (1874–1963)
