Abstract:

The effect of four fly ashes on strength development and heat-of- hydration characteristics of portland cement-fly ash mixtures was investigated. These comprised three Class F and one Class C fly ash. Mixtures was 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 concrete were investigated. Keywords Concreteconstruction materials Chemical properties Strength mechanics Damslocks waterways.
