This design manual is the second of two volumes pertaining to the use of fly ash as a construction material in road and site development applications. Volume 1 describes the use of fly ash conditioned with small amounts of water to produce a solid, soil-like material. Volume 2 describes the use of fly ash mixed with sufficient water to create a fluid or semi-fluid material. In most applications, Portland cement is added to the mixture to provide the desired level of strength. In some applications, aggregate filler is also added to the mixture to improve the durability of the mix. The flowable nature of these materials determines the manner in which they are handled, placed, and used in construction. The following uses are discussed: Slurry Backfills; Grouting; and Hydraulic Fills. Miscellaneous uses are also discussed, including the use of fly ash in high fly ash content concrete, unsintered synthetic aggregate, and slurry walls. Also included are three appendices containing additional information of interest to the designer: Mix Design; Laboratory Test Procedures; and a Bibliography.
