On the tensile resistance of UHPC at impact

The European Physical Journal Special Topics, 2018
Ultra-High Performance Concrete (UHPC) is a new class of concrete which shows high strength and durability. In this paper experimental investigations on the dynamic properties of a low-silica UHPC are presented. By means of Hopkinson Pressure Bar experiments the dynamic elastic modulus and the tensile resistance of the material are determined ...

Monitoring the Degradation of UHPC Boards

Applied Mechanics and Materials, 2015
In this article the hot water test is presented on thin UHPC slabs that are reinforced by a new type of armature. It is a textile armature, which should replace the classic metal (steel) armature. Textile armature should not only reduce the cost of production, but, because it is not susceptible to corrosion as conventional steel armature, panels can be

Numerical Modelling on Tensile Behavior of UHPC Joint in Steel-UHPC Composite Bridge Decks

IABSE Reports
<p>Ultra-high performance concrete (UHPC) exhibits exceptional mechanical properties and durability, making it widely adopted as a reinforced overlay to strengthen fatigue-cracked orthotropic steel bridge decks. However, the casting of massive UHPC creates interfaces between pre- and post-cast zones, resulting in potential weak points under ...
