摘要:Durability and mechanical properties of UHPC help to develop solutions to upgrade structures. Cementitious UHPC concrete has a minimum specified compressive strength (120-150 MPa), superior resistance to compression, ductility, eco-efficiency and insulation. It is usually used with fibres included to achieve the specified requirements of the mixture. Sprayable UHPC types for inclined applications and leave leave-in-place form solutions have been developed and are used for repair and strengthening purposes. A combination of UHPC and post tensioning is used to create an optimal reinforcement solution. UHPC represented an innovation in post-tensioning for the first time in the United Kingdom, creating a possibility to cast anchoring blocks that are compact, aesthetically pleasing and safer to install. Prefabricated anchors for the bridge exterior and anchors poured on site for the bridge interior were used. UHPC-steel composite deck is an effective solution to improve a steel bridge’s strength and stiffness. Studies of overlays in bridge decks showed that UHPC substrates exhibit a higher bond strength than normal strength concrete (NSC) and further analysis of techniques for bonding surfaces with UHPC. Future tendencies about structure improvements using UHPC and GFRP are reviewed.
