Abstract
Utilization of coal ash as a geomaterial solves a solid waste problem and provides needed construction material. This paper presents the effect of cement additions on the unconfined compressive characteristics of compacted coal ash to promote coal ash recycling. The unconfined compressive strength of the samples drops off sharply on the wet side of optimum water content, whereas on the dry side, the unconfined compressive strength increases with increasing the water content. In addition increasing cement additions lead to increase in strength and stiffness. Several empirical relationships between unconfined compressive strength and curing time have been also developed The unconfined compressive strength of compacted coal ash containing cement at 96% of optimum water content increased more than those at all other water contents.
