Second International Interactive Symposium on UHPC, 2019 Despite a recent high-profile application at Hammersmith Flyover, adoption of Ultra High Performance Concrete (UHPC) in the UK remains limited. This contrasts with use globally which continues to grow. A state of the art study was undertaken on behalf of Highways England, the government-owned company responsible for operating and maintaining the UK’s ...

Towards Efficient Use of Cement in Ultra High Performance Concrete
Nordic Concrete Research, 2021 This paper presents an investigation on substituting the cement content with an inert material, in a typical locally produced UHPC mix. A structured literature review was performed to enrichen the discussion and to benchmark the results towards already ...

The feasibility of using ultra-high performance concrete (UHPC) to strengthen RC beams in torsion
Journal of Materials Research and Technology, 2023 To explore the feasibility of using ultra-high performance concrete (UHPC) to strengthen reinforced concrete (RC) beams in torsion, pure torsion tests on 9 specimens have been conducted in this study, including one RC beam without strengthening (referred

Utilizing Full UHPC Compressive Strength in Steel Reinforced UHPC Beams
Second International Interactive Symposium on UHPC, 2019 Steel reinforced ultra-high performance concrete (R/UHPC) flexural members commonly fail by fracture of the steel reinforcement after crack localization rather than crushing of the cement-based matrix as expected in traditional reinforced concrete. When failing after crack localization, R/UHPC specimens show low drift capacity and the high composite ...

Experimental investigation on UHPC shrinkage of full-scale steel-UHPC composite bridge deck
Developments in the Built Environment, 2023 Three full-scale composite bridge deck segments with various steel-to-UHPC area ratios, as well as free shrinkage specimens, were tested to investigate the restrained shrinkage and cracking behaviors. Based on the measured UHPC strain and temperature, the variations in shrinkage strain were analyzed, and a time-varying analysis theory for calculating ...

Ultra-high performance concrete reinforced with macro fibres recycled from waste GFRP composites
Case Studies in Construction Materials, 2023 Ultra-high-performance concrete (UHPC) is a promising cementitious composite to produce lightweight and high-performance structures. Steel fibres are an essential constituting material of UHPC to prevent the brittle failure of UHPC, but the high cost ...
