| Abstract: |
“Structural UHPFRC” stands for Ultra‐High‐Performance Fibre Reinforced Cementitious Composite material which is complemented by reinforcing and prestressing steel to enhance the resistance and durability of structural elements. Properties of impermeable, tensile strain hardening UHPFRC are discussed in view of structural applications. Two fundamental concepts to enhance concrete bridges have been developed by research and validated by numerous applications, mostly in Switzerland: 1) Rehabilitation and strengthening of existing concrete structures by adding a layer of structural UHPFRC, and 2) Construction of new structures in Structural UHPFRC, often composed of precast elements. These applications show that “Structural UHPFRC” has made its proof as a novel building material and technology to enhance bridges and structures in general. UHPFRC also contributes in lowering the environmental impact of structures and thus improving sustainability. UHPFRC is at the beginning of a new construction era: the “post‐concrete era”. |
