The ReSHEALience project

Objectives

The main goal of the project ReSHEALience is to develop an Ultra High Durability Concrete (UHDC) and a Durability Assessment-based Design (DAD) methodology for structures, to improve durability and predict their long-term performance under Extremely Aggressive Exposures (EAE: XS-chloride induced corrosion, XA-chemical attack). The improvement will be supported upgrading Ultra High Performance Fiber Reinforced Concrete with new functionalities. Focus will be on marine structures and infrastructures for geothermal/biomass energy plants, whose severe conditions challenge the performance, lead to quick deterioration and shorten the lifespan, resulting in billions Euro spent each year in repairs.

This goal will be achieved through the following activities (variations compared to current high performance reinforced concrete).

• ■ Tailoring UHDC to target a 100% enhancement in material durability.
• ■ Upgrading experimental methods to validating durability properties of UHDCs in service conditions (cracked state) and validate an enhancement of at least a 30%.
• ■ Developing a theoretical model to evaluate ageing and degradation of UHDC structures in EAE with a 75% of accuracy, extending the modelling to predict the lifespan.
• ■ Proposing new design concepts DAD, for the use of UHDC and assessing the structures durability and Life Cycle Analysis with a 95% confidence level, to achieve an increase service life of 30%, and a long-term reduction of maintenance costs.
