Client is the Manateq Economic Zones Company, located in Qatar, more information about the project see www.manateq.qa. Contractor and producer of the beautiful and impressive Ultra High Performance shading elements is the local prefab and GRFC-company DCS Doha Cladding Solutions. A paper about the technical details can be downloaded here Concrepte Plant International CPI 3/2020 about Manateq.
Doha in Qatar
UHPC Recipe with a compression strength fcm > 150N/mm² with aggregates from India. Steel fibers from China, PCE sourced from a local supplier. Binder is Nanodur Compound 5941 of Dyckerhoff GmbH. Consultancy to recipe, mixing technology and production was performed by durcrete GmbH. Only one visit in Doha was necessary to transfer the How-How.
Office Building VR-Bank Krefeld
The UHPC façade is produced by Benno Drössler GmbH & Co Bauunternehmen KG in Siegen, Germany. The client is the Volksbank Krefeld eG, the design is performed by Gerber Architects. The new building in Krefeld is occupied in the spring of 2015.
Office Building Ferchau
The contractor for the UHPC façade is Benno Drössler GmbH & Co Bauunternehmen KG in Siegen. The client is FFI Frank Ferchau Immobilien, the design is by Gerber Architects. The new building in Gummersbach was occupied in the autumn of 2011.
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.bauing.uni-kl.de/massivbau/; 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.
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/.
Charging Stations for Electromobility
‘Design for eternity’ is what PION AG promises for its organically shaped charging stations made of concrete. The column consisting of three parts
are made of grey exposed concrete. Alternatively it may be equipped with titanium dioxide to reduce nitrogen oxides in the air. The company emphasizes environmentally friendly products, which can be recycled easily. They also offer smart charging boxes for wall mounting. More info at www.pion-ag.com.
The look of spatial 3D images made of concrete is enhanced by coating with oil and paint. The template for the milled plastic mold was a spatial CAD model created by durcrete.
Architectural and Terrain Models
For the archaeological park about the cloister Elisabethenzell between Frankfurt and Nuremberg, the ToBo Medien Production realized this model, which shows the historical buildings in the 13th century.
