UHPC/UHPFRC: material concept and structural design

It shows some initial aspects related with the materials, composition, mix design, properties and characterization of the properties of a UHPFRC. The material behaviour at fresh and hardened state is considered, and typing recommendation for the material are exposed. General design criteria, both at sectional and structural level are commented thinking in present the basis to adapt to the particular requirements.

UHDC to enhance the durability of structures. Testing and identification of parameters

The talk deals with the relevance role of concrete characteristics to improve the durability of concrete structures. Concrete innovation and challenges in the 21st century are addressed. The evolution of concrete technology and the incorporation of new additives to reach ultra-high durability concretes is analysed and compare with respect to more conventional concretes. Aspects considered are related to the relevant parameters that characterise the durability of concrete according to the aggressiveness of the environment under operation. Key performance indicators for the durability assessment are under evaluation. Concrete technology plus the incorporation of suitable concrete constituents to enhance concrete durability, in concrete to resist the aggressiveness of the environment, in reinforcement to prevent from corrosion and crack control to improve durability through crack sealing.

Principles of durability based design

The presentation will provide the description of the framework and methodology for Durability Assessment based Design approach for structures made of/retrofitted with the Ultra High Durability Concrete materials conceived, produced and investigated in the project ReSHEALience.
The innovative design concept informing the whole approach will be formulated shifting from a set of prescriptions, mainly referring to material composition and also including, in case, an allowable level of damage defined and quantified in order not to compromise the intended level of “passive” protection of sensitive material and structural parts (deemed-to-satisfy approach; – avoidance-of-deterioration approach),  to the prediction of the evolution of the serviceability and ultimate limit state performance indicators, as relevant to the application, as a function of scenario-based aging and degradation mechanisms.
