ABSTRACT
The basic conceptual idea is to use UHPFRC only in those zones of the structure where the outstanding UHPFRC properties in terms of durability and strength are fully exploited; i.e. UHPFRC is used to “harden” the zones where the structure is exposed to severe environmental conditions (f.ex., deicing salts, marine environment) and high mechanical loading (f.ex. impact, concentrated loads, fatigue). All other parts of the structure remain in conventional structural concrete as these parts are subjected to relatively moderate exposure.
