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.
