Upgrading of an existing highway bridge in Austria by use of NANODUR® concrete. The ready mixed UHPC concrete was delivered with a truck mixer. The scientific monitoring was carried out by the Institute of Structural Concrete, Graz University of Technology, Prof. Nguyen Viet Tue. More information see article in “Beton- und Stahlbetonbau”, 2/2015.
Floodwater Protection at a Bridge
At the Walser-Bridge in Oberstdorf/Germany, a highly resistant protective layer was placed on the outside of the bridge beams. The design was performed by Dr. Schütz Engineers www.drschuetz-ingenieure.de. The execution of the three-dimensional elements was done by R. Bayer Concrete Plant in Blaubeuren/Germany www.betonwerkstein.de.
Weir system with UHPC
For the water system of the baroque garden in Zabeltitz (north of Dresden/Germany) the weirs were renewed. Prefab components made of Ultra High Performance Concrete were integrated in the construction. The design was carried out by the engineering company Koban + Schuckert in Dresden. The construction of the curved UHPC-parts was done by Bad Lausick Concrete Plant www.betonwerk-bbl.de .
Recirculation Aqua Culture
Green Aqua Farming develops recirculation aqua culture for sea fish and shrimps made of Ultra High Performance Concrete -UHPC. The picture shows the erection of a 35m long, two storied shrimp basin. The construction developped by Benno Drössler GmbH & Co KG is glued and the concrete has no additional lining. Details see www.greenaquafarming.de.
Parabolic Shells for DESERTEC
The Technical University of Kaiserslautern and the Ruhr University in Bochum designed this shell for a parabolic trough power plant. In a second step, a demonstrator in original scale was buildt by Concrete Plant Stanecker. More infos see www.massivbau-kl.de; Download of the first PHD-Theses (German Language) at Dissertation_Mueller. Link to a video which shows the element in motion at YouTube: http://www.youtube.com. Background information see News from Dyckerhoff.
The parapet elements of 8 mm thickness for this multifamily dwelling were installed in the summer of 2008 in exchange for the burst glass panels. The left parts of the Ultra High Performance Concrete elements were reinforced with steel fibers, the right UHPC-parts are free from fibers. No cracking due to temperature, frost, impact etc. had occured within the last 10 years.
Shot-Resistant, Break-In-Resistant, Explosion-Resistant Façades
Shot-resistant façades can be achieved using the recipe durcrete ‘shot’. With a slenderness of 7 cm, no piercing or spalling will happen under impact of solid-core ammunition calibre 7.62 x 51 mm (class 7 acc. EN 1063 oder EN 1522/1523). Resistance class RC6 to manual burglary attempts acc. EN 1630. Panels can be delivered from Germany or produced in a local prefab plant. More Infos see www.durcrete.de/downloads/.
Façades with laminated foils
A simple method of relocating sales from downstream trades like plaster, tiles, coatings and claddings toward the precast plant is to coat or laminate the concrete surfaces with special foils. Durcrete and Prilhofer Consulting [www.prilhofer.com] have specialized in this field of added value and are advising prefab plants on this new topic in the whole world.
