| Résumé : | Cement-based materials (CBM) are the foremost construction materials worldwide. Therefore, there are widely accepted standards for their structural applications. However, for service life designs, current approaches largely depend on CBM strength class and restrictions on CBM constituents. Consequently, the service life behaviour of CBM structures is still analysed with insufficiently rigorous approaches that are based on outdated scientific knowledge, particularly regarding the cumulative behaviour since early ages. This results in increased maintenance/repair costs from early ages, and reduced service life of structures, with consequential economic/sustainability impacts, despite the significant research advances that have been achieved in the last decade. This special issue concentrates the current technological trends worldwide as they were presented in the 2nd International RILEM/COST Conference on Early Age Cracking and Serviceability in Cement-Based Materials and Structures organized in Brussels on 12 to 14 September 2017. It includes all aspects of cement based materials with emphasis on innovative testing methodologies, numerical modeling and development of products as studied in top international laboratories members of COST action TU1404. It represents the state of the art in this area, and it aims to bring this knowledge to the broadest possible audience and accelerate knowledge transfer creating avenues for new developments. |
