Abstract:

The pozzolanic properties of fly ash, which enable it to react with lime to form cementitious products, have made fly ash a good quality base or subbase course material when used with lime or cement to stabilize aggregates and soils, or when used alone with lime or cement. Strength and durability criteria have been established for this application, and appropriate testing procedures have been developed. Construction procedures utilize standard equipment and techniques for central mixing or mix in-place operations. Fly ash is used as embankment or structural backfill material over weak or compressible soils because of the reduced surcharge that results from its light unit weight. In addition, its good shear strength properties result in low compressibility and good stability characteristics. Economies can be realized in the design of retaining structures backfilled with lightweight fly ash. Fly ash improves the flow properties and strength characteristics of grouts. It can be used alone for void-filling, or used in conjunction with Portland cement, lime, clay, sand, and gravel to develop grouts for applications related to highway structures.
