WP 5 deals with UHPFRC (Ultra High Performance Fibre Reinforced Concretes) to locally harden structures in zones of severe environmental and mechanical loading. Their efficiency has been validated in the framework of project SAMARIS on the basis of specific recipes with components from a single origin. Further, the research and developments works in project SAMARIS indicated several domains where UHPFRC could be further improved to widen their spectrum of applications for rehabilitation. Starting from this basis, the main scientific objectives of WP 5 are: (1) determine the effect of surface roughness of substrate on tensile response of UHPFRC, (2) determine the effect of the UHPFRC composition on its rheological behaviour on inclined surfaces, (3) develop a non-destructive technique for the characterization of the fiber distribution in UHPFRC.
The main objective of this WP is to demonstrate that this technique can be successfully and price-efficiently implemented with local products, in NMS.
