Abstract:

This paper summarizes the results of two research studies aimed at evaluating the properties and possible environmental effects of bituminous and lignite coal based fly ashes stabilized with lime or cement. Two bituminous (class F) ashes from northern and central West Virginia and two lignite (class C) ashes from western Turkey were incorporated in the studies. Standard ASTM test properties of the ashes, and the compaction, strength, durability, permeability, and leachate properties of the stabilized ashes were evaluated in the laboratory. The results were found to be generally favorable, indicating that both classes of fly ash can be successfully stabilized with cement or lime to produce a pavement or liner material without any adverse effects on the environment.
