- Synopsis
- The use of binders using ground granulated blast-furnace slag, which is one of the initiatives for concrete materials aimed at reducing environmental impact, bears consideration. A vast amount of knowledge about blast furnace cement Class B has been accumulated over the years and its use has been steadily promoted. On the other hand, the use of cement with a high substitution rate that is equivalent to blast furnace cement Class C has not made much progress. This paper gives an overview of the Recommendations for Design and Construction of Concrete Using Ground Granulated Blast-Furnace Slag, which have been revised for the first time in a quarter century. The content was revised in line with the 2017 Standard Specifications for Concrete Structures to allow design and construction based on the latest standards. Further, newly obtained knowledge and new usage methods have been summarized in the Appendix.
