Abstract:An experimental program which aimed at investigating the behavior of SCC containingClass F fly ash has been carried out. The fresh state properties of the concrete wereassessed using methods of segregation and flow. The rheology of the paste matrix wasalso characterized and compared with a previously developed paste rheology model. Inaddition, compressive strength, chloride permeability, and mold-finish were evaluated. The results indicate that it is possible to develop a SCC containing Class F fly ash that is high performing in its fresh state. Furthermore, the addition of fly ash was shown toreduce superplasticizer dosage, increase workability, and increase overall chloride permeability resistance. In addition, it was determined that the difference of densities between the aggregate and matrix influence the results of a previously developed pasterheology model.
