- Synopsis
- In December 2021, the Subcommittee on the Revision of Guidelines for High Fluidity Concrete of the Architectural Institute of Japan revised the “Recommendations for Mix Design and Construction Practice of High Fluidity Concrete” established in 1997 for the purpose of popularizing, standardizing and systematizing high fluidity concrete in the construction field. This paper describes the background to the revision of these Recommendations, the contents of the study, and the outline of the revision of this guideline. It is hoped that these Recommendation will help further disseminate and improve the quality of high fluidity concrete technology.
