Abstract:
Current solutions for new concrete constructions in Extremely Aggressive Exposures, as recommended and enforced by design codes, are not considering new cement‐based construction materials, such as Ultra High‐Performance Fiber Reinforced Concrete, neither new constituents specifically conceived to improve the concrete durability, because of the lack of standards and technical awareness by most designers and contractors. The H2020 ReSHEALience project will upgrade to the concept of Ultra High Durability Concrete (UHDC), combining nano‐scale constituents (nano‐cellulose, alumina nanofibers) and self‐healing promoters (crystalline admixtures). The paper will present the approach pursued in the project to design the tensile performance of UHDC mixes as a function of the type and scenario of application, together with a synopsis of the results of ongoing research.
