Revised Recomnendation for Construction of Concrete Containing Ground Granulated Blast-furnace
Slag as an Adnulxture of Recommendation for Design and Construction of Concrete Containing Ground
Granulated Blast-furnace Slag as an Admixture which had been drafted at 1988 in Japan is presented
The replacement ratio of ground slag covered by this Recommendation is in the range equivalent
to replacing 30% to 70% of portland cement. Three types of ground slag by the specific surface :
ground slag 4000 (with a specific surface of 3000 to 5000 cm’/g) , ground slag 6000 (5000 to 7000
cm?/g) , and ground slag 8000 (7000 to 10000 cmz/g) are specified according to JIS A 6206 (Ground
granulated blast—furnace slag for use in concrete).
Keywords = recorrmendation, ground granulated blast-furnace slag, mineral admixture, concrete construction
