Numerical Modeling Strategies for Sustainable Concrete Structures (SSCS 2022)

Cement is the main constituent of concrete, the most widely used building material today and which will continue to be in the years to come. Its production generates CO2 emissions. It is, thus, of primary importance to optimize the utilization of cement in concrete constructions, while checking that these constructions have lifespan compatible with the stakes of the sustainable development. It is essential, to take up the challenge, to use adapted tools of quantification making it possible to rigorously and reliably justify the strategic and technical choices adopted. Numerical methods (finite elements, finite volumes, finite differences) constitute a relevant response to this challenge. They make it possible to optimize concrete constructions because they can take into account complexities linked to the rheological, physicochemical, mechanical properties of concrete, the geometry of structures or even environmental boundary conditions. This optimization must also respect constraints of time, money, safety, energy, CO2 emissions, and, more generally, life cycle, in a way more reliable than the codes and analytical approaches currently used. After Aix-en-Provence (France, 2012), Rio de Janeiro (Brazil, 2015) and Lecco (Italy, 2019), the next RILEM international Conference SSCS will take place in the city of Marseille (France) from July 4 to 6 2022.
