Abstract:
The use of iron blast furnace slag as a constituent of concrete, either as aggregate or as a cementing material, or both, is well known. The use of ground granulated blast furnace (GGBF) slag in the production of blended cements began in 1896 in the United States. Since about 1950, attention has been given to the use of GGBF slag as a separate cementitious constituent of concrete. This report addresses both the use of GGBF slag as a separate cementitious material added along with portland cement in the production of concrete and the use of blended cements containing GGBF slag. Slags, other than those derived from a blast furnace used for the production of iron are not discussed in this report. The reader should be aware that the material characteristics described and the recommendations for use pertain solely to GGBF slag. The proper use of GGBF slag increases workability of portland cement concrete, increases resistance to sulfate attack, reduces permeability, reduces chloride-ion diffusion into concrete, and reduces the likelihood of deterioration due to alkali-silica reaction.
