ABSTRACT:
Ground bottom ash, a waste material derived from combustion of coal, which presents a disposal problem, replaces part of the cement in a cementitious material useful in concretes and mortars and provides compressive strengths in concretes comparable with or better than corresponding cements in which there is no replacement of cement by ground bottom ash and cements containing fly ash.
