SOIL STABILIZATION USING A WESTERN COAL HIGH CALCIUM FLY ASH

Fly ash, a pozzolanic by-product of coal burning power plants, is an abundant potential source of highway and embankment construction material. Some fly ashes are suitable for use as a supplement or replacement for lime and portland cement in soil stabilization applications. The paper discusses a study made of fly ash produced from Wyoming coal, which contains 20% CaO, causing it to react something like quick lime. In addition, the fly ash takes a pozzolanic set when mixed with water. Reported are the engineering properties of this fly ash and fly ash-soil mixtures.
