Abstract

Self-compacting concrete requires a high powder content or a viscosity agent (VA) to increase its segregation resistance. This paper presents the results of a preliminary study on the utilization of rejected fly ash (r-FA) as part of the powder content. r-FA is unsuitable in the production of blended cements simply due to its coarseness. Preliminary results suggested that r-FA could be used to replace VAs in the production of self-compacting concrete (SCC) and, possibly, with additional benefits. A detailed research project is under development based on results of this study.
