Flexural Performance of the UHPC Deck in a Novel Steel-UHPC Composite Girder
IABSE Reports, 2017<p>This paper investigated the flexural performance of the UHPC deck based on Fifth Nanjing Yangtze River Bridge which is the first long-span cable-stayed bridge in China utilizing reinforced UHPC with basalt. Two types of the specimens were used to reveal the longitudinal and transversal flexural performance of the UHPC deck, respectively.

Metakaolin in the formulation of UHPC
Construction and Building Materials, 2009Silica fumes have characteristics that make them exceptional in cement matrices and, in particular, in UHPC. Nevertheless, they have important disadvantages: lack of availability, cost and color. The search for substitute products thus appears important if the use of UHPC is to become more widespread in the concrete industry, e.g.

The UHPC Catharinabridge in Leiden
2017An extremely slender bridge made from Ultra High Performance concrete (UHPC) has been built at a prominent location in the center of Leiden. With a length of 36 m and a slenderness ratio of 1:81 this is the longest and most slender UHPC-bridge in the Netherlands. Seen from above the bridge is shaped like an S.

Structural Behaviour of UHPC with Micro-Reinforcement
IABSE Reports, 2017<p>With intent to provide a ductile failure and to use Ultra High Performance Concrete (UHPC) to full capacity usually steel fibres are added during the mixing process. The impaired workability as well as random orientation and spreading of the fibres, the increased environmental pollution and the cost factor are beside the spots of corrosion ...

Microstructural investigation of innovative UHPC
Cement and Concrete Research, 1999The production of ultra high performance concrete (UHPC) with target strengths greater than 200 MPa has recently been considered for specific structural applications that need this enhanced mechanical performance. The main purpose of developing these innovative UHPC mixtures is to produce high-strength precast concrete elements with excellent ...
