Abstract:
Describes research on the effect of fly ash on the properties of silica fume concrete. The ratio of silica fume to cementitious material varied from 10 to 30 percent, 20 percent of the portland cement was replaced by fly ash, and aggregate content varied. Properties measured were slump, compressive strength, flexural strength, permeability, and permeable void ratio. The fly ash appeared to enhance workability, but increased the permeability of silica fume concrete.
