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.
