Description: Miscellaneous Paper
Abstract: The effect of four fly ashes on strength development and heat-of-hydration characteristics of portland cement-fly ash mixtur es was investigated. These comprised three Class F and one Class C fly ash. Mixtures containing Class C fly ash gained strength more rapidly than mixtures containing Class F fly ash. At 2 days, heat of hydration was reduced by all fly ashes, but the Class C fly ash contributed substantial heat at later ages, exceeding pure portland cement in some mixtures. The consequences of using Class C fly ash in mass concr ete were investigated.
