Title: Microstructures and Properties of Granulated Slag-Portland Cement Blends at Normal and Elevated Temperatures
Author(s): D.M. Roy and K.M. Parker
Publication: Special Publication
Appears on pages(s): 397-414
Keywords: blast furnace slag; compressive strength; heat of

Abstract:Blends of separately ground (fine) granulated blast furnace slag with portland cement generally possess properties equivalent to or in ways superior to typical portland cements. Heats of hydration, apparent activation energies for reaction, and structure development are modified in high slag content mixtures. By three days the strength development of blends is equivalent to that of pure portland cement at normal temperatures but this stage is achieved more rapidly at elevated temperatures, while a very fine pore structure is developed with longer time. Phase changes, microstructural and property development including permeability development as a function of time are discussed.
