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:
“I know of the sleepy country, where swans fly round
Coupled with golden chains, and sing as they fly.
A king and a queen are wandering there, and the sound
Has made them so happy and hopeless, so deaf and so blind
With wisdom, they wander till all the years have gone by....”
—William Butler Yeats (1865–1939)
“Of the crow-blue mussel shells, one keeps
adjusting the ash heaps;
opening and shutting itself like
an
injured fan.”
—Marianne Moore (1887–1972)
“For me, the child is a veritable image of becoming, of possibility, poised to reach towards what is not yet, towards a growing that cannot be predetermined or prescribed. I see her and I fill the space with others like her, risking, straining, wanting to find out, to ask their own questions, to experience a world that is shared.”
—Maxine Greene (20th century)
