Abstract:
Summarizes an investigation of seven low-calcium (ASTM Class F) fly ashes in high-volume (58 percent of the total cementitious material content) fly ash concrete. Large dosages of a superplasticizer were used to obtain the required workability. Concrete specimens were tested for compressive strength, modulus of elasticity, creep strain, and resistance to chloride-ion diffusion at various ages up to one year. Most of the fly ashes investigated indicated a potential for use in high-volume fly ash concrete.
