Delayed Casting of UHPFRC Elements

Key Engineering Materials, 2019
Because of high durability and excellent material properties, innovative (thin-walled, shell) structures should be designed. Ultra - High Performance Fiber Reinforced concrete might be used for a specific application with very complex design and very complex shape.

Segmented footbridge made of UHPFRC

IABSE Reports, 2019
<p>The paper deals with the design and production of a segmented prestressed bridge made of Ultra High Performance Fiber Reinforced Concrete (UHPFRC) The footbridge is installed in the town of Příbor in Czech Republic. The UHPFRC or UHPC material in the Czech Republic gradually finds its way to interesting and unique design applications.

Feinprofilierte UHPFRC‐Trockenfugen für Segmentbauteile

Beton- und Stahlbetonbau, 2013
AbstractGegenüber der Ortbetonbauweise hat die Segmentbauweise mit Betonfertigteilen viele Vorzüge. Diese liegen zum einen in der qualitätsgesicherten und witterungsunabhängigen Vorfertigung im Fertigteilwerk, einer verkürzten Bauzeit sowie besseren Rückbaumöglichkeiten.

Verbundverhalten von CFK‐Spannbewehrungen in UHPFRC

Beton- und Stahlbetonbau, 2013
AbstractDie Kombination einer vorgespannten CFK‐Bewehrung (Carbonfaserverstärkter Kunststoff) und UHPFRC (Ultra High Performance Fiber Reinforced Concrete) ermöglicht es, filigrane und weitgespannte Konstruktionen zu errichten, insbesondere wenn es sich um gefaltete und gekrümmte Schalen handelt. Wegen der Unempfindlichkeit gegenüber Korrosion wird die

Cyclic behavior of UHPFRC under compression

Cement and Concrete Composites, 2019
Abstract The research field of constitutive modeling ultra-high performance fiber reinforced concrete (UHPFRC) is in current development. Few experimental results were reported for the material under uniaxial low-cycle loading, and consequently, there is a gap in constitutive propositions to predict its behavior. Thus, one purpose of this research is

Querkraftversuche an profilierten Spannbetonträgern aus UHPFRC

Beton- und Stahlbetonbau, 2019
AbstractUltrahochfester faserbewehrter Beton (UHPFRC) ist ein Faserverbundwerkstoff, der durch sehr hohe Dichtigkeit und Festigkeiten charakterisiert ist. Dadurch ergeben sich im Fertigteilbau, insbesondere für Spannbetonträger, völlig neue Möglichkeiten für gewichtsreduzierte, schlanke und dauerhafte Konstruktionen.
