Abstract:
This article presents the characterizations of mechanical and durability properties on diverse concrete formulas with a lower carbon footprint. The contribution of mineral additions in the binder is currently limited by the NF EN 206/CN (2022) standard with the concept of the equivalent binder. It is now necessary to change these normative provisions to expand low-carbon concrete solutions and accelerate their development in construction. The objective of this study is to formulate concretes based on ternary binders and to evaluate their use properties compared to traditional concrete defined today in the normative context. Several types of addition have been used to form ternary binders: limestone addition, blast-furnace slag, and flash metakaolin. The results obtained with substitution rates ranging from 40% to 60% of clinker have allowed positioning these different concretes regarding the thresholds defined for the performance-based approach according to FD P 18-480 (2022).
