workable and strong UHPC dry mix

Ultra High Performance Concrete (UHPC) is attracting increasing international attention. This concrete is a cement bonded material with excellent mechanical properties. These include compressive strengths, which are in the range of steel strengths, as well as a high density, which leads to water and gas impermeability. The UHPC material is not only used in the building industry - e. g. curtain walling of UHPC facades, but also increasingly in the fields of product design, interior design and mechanical engineering.

 

G. tecz Engineering has developed two UHPC ready-to-use mixes that meet the requirements of the different application areas: Grayshape and myUHPC.

Both ready-mix concrete mixes are easy to process and develop correspondingly high mechanical properties. The UHPC Grayshape achieves compressive strengths of approx. 120 N/mm2 and flexural tensile strengths of 15 N/mm2 or more (measured on a standard specimen). myUHPC, on the other hand, achieves compressive strengths of 165 N/mm2 or more when using larger compulsory mixers. The material has been developed not only in terms of compressive strength, which is not necessary in many cases, but also for simple mixing, easy processing and excellent fair-faced concrete surface properties.

 

G. tecz customers say: "I have to say the material is absolutely amazing!  We never came across such a workable and strong concrete". Dror Kaspi, ARDOMA DESIGN

 

The ready mix can be ordered in smaller quantities via the website myUHPC.com . For major customers, G. tecz Engineering offers the individual development of their own cost-effective UHPC, based on their own raw materials.

Le béton ultra haute performance (BHP) attire de plus en plus l'attention internationale. Ce béton est un matériau lié au ciment avec d'excellentes propriétés mécaniques. Il s'agit notamment des résistances à la compression, qui sont comprises dans la gamme des résistances de l'acier, ainsi que de la haute densité, qui conduit à l'imperméabilité à l'eau et au gaz. Le matériau UHPC n'est pas seulement utilisé dans l'industrie du bâtiment - par exemple pour les façades UHPC, mais aussi de plus en plus dans les domaines de la conception de produits, du design d'intérieur et de la construction mécanique. 

 

G. tecz Engineering a développé deux composés prêts à l'emploi UHPC répondant aux exigences des différents domaines d'application: Grayshape et myUHPC.

Les deux mélanges de béton prêt à l'emploi sont faciles à travailler et développent des propriétés mécaniques élevées. L'UHPC Grayshape atteint une résistance à la compression d'environ 120 N/mm2 et une résistance à la flexion de 15 N/mm2 ou plus (mesurée sur un échantillon standard). myUHPC, par contre, atteint une résistance à la compression de 165 N/mm2 ou plus en cas d'utilisation de mélangeurs obligatoires de plus grande taille. Le matériau a été développé non seulement en termes de résistance à la compression, ce qui n'est pas nécessaire dans de nombreux cas, mais aussi pour un malaxage simple, une mise en œuvre facile et d'excellentes propriétés de surface du béton.

 

Les clients de G. tecz disent:"Je dois dire que le matériel est absolument incroyable!  Nous n'avons jamais rencontré un béton aussi solide et maniable." Dror Kaspi, ARDOMA DESIGN

 

Le mélange prêt à l'emploi peut être commandé en petites quantités sur le site web myUHPC.com . Pour les grands clients, G. tecz Engineering propose le développement individuel de ses propres UHPC économiques à partir de ses propres matières premières.

Innovation Beton

Material, Maschine, Produktion - Forschungs- und Entwicklungsdienstleister G.tecz Engineering aus Kassel bittet Service von A-Z rund um innovative Betontechnologien.

>> Beton ist eines der am meisten genutzten Materialien der Welt aber auch eines der ältesten. Der Wandel in Materialtechnologie, Produktionsverfahren und stetige Innovationen machen nicht halt vor dem alt bekannten Baustoff. Im Gegenteil, in den vergangenen 15 Jahren wurden neben neuen Betontechnologien auch einhergehend neue Produkte, Herstellungsverfahren, Digitalisierung (Industrie 4.0) oder Anwendungen entwickelt, die bis dato nicht vorstellbar waren.

 

Hersteller von modernen Betonelementen, ob es sich hierbei um kleine Familienunternehmer, Mittelständler oder große Konzerne handelt, müssen hierbei Schritt halten. Seit 10 Jahren bietet das Kasseler Unternehmen G.tecz Engineering erfolgreich Ingenieur- und Beratungsdienstleistungen rund um Zement gebundene Werkstoffe an - weltweit. << ...

Concrete Innovation

Concrete is one of the most widely used materials in the world, but it is also one of the oldest. The change in material technology, production processes and constant innovations do not stop at the old known building material. On the contrary, in the past 15 years new concrete technologies have been developed alongside new products, manufacturing processes, digitisation (industry 4.0) and applications that were previously unimaginable.

 

Manufacturers of modern concrete elements, whether they are small family businesses, medium-sized companies or large corporations, must keep pace with this trend. For 10 years, the Kassel-based company G. tecz Engineering has been successfully offering engineering and consulting services for cement bonded materials - worldwide. The services are individually tailored to the partners' needs and range from simple concrete optimization in existing production facilities to project and change management, through to complete production or plant planning on a greenfield site, including business and strategy consulting; this is always industry- and implementation-oriented. 

Manufacturers of prefabricated elements, concrete producers or companies dealing with cement-bonded materials can only be competitive if their material technologies meet today's requirements, are suitable for products and the internal production processes run efficiently and safely.

 

Two practical examples: 

 

For a small medium-sized company producing prefab elements, a holistic analysis was carried out, i. e. from material composition to production technology, production processes and employee know-how. By optimizing the concrete formulation, which no longer corresponded to the state of the art, it was possible to achieve cost savings of approx. 20% and at the same time increase the material class and fair-faced concrete class. With a minimal reorganization of the production processes, employee training and modern concrete technology, the efficiency of the company was increased by approx. 15%.

 

Filigree façade elements made of high-strength or ultra-high-strength concrete (UHFB, UHPC) are becoming more and more interesting for the market of individual curtain wall façades. The company housefabrik GmbH offers complete solutions for this purpose for prefabrication plants or lateral entrants, which were developed by G. tecz Engineering. In an integrated development process, the material technology and the facade production plant were coordinated, optimized and implemented with partners. The efficiency of the plant enables a high production rate and ensures the competitiveness of the housefabrik customers.

 

Company know-how, employees, material technology, innovative products and production processes are the most valuable resources of a company. G. tecz offers individual, future-oriented technologies and concepts to increase the competitiveness of a company in cooperation with its team.

Workshop - Philosophie & Technik

Weiter denken ....

Unser Workshop richtet sich an Ingenieure, Techniker, Architekten, Designer und andere technische Berufe. Innovationen werden möglich, wenn man etablierte Bahnen und starre Konzepte verlässt. Das Neue kann nicht geplant werden. Die WERKSTATT FÜR ZWECKFREIEN NUTZEN des Künstlers Michael Evers bietet einen Raum für kreative Improvisation. Hier können Technologie und Rationalität mit den Augen der Philosophie gesehen werden, künstlerische Experimente mit Farbe und Zeichenstift eröffnen innere Freiheiten für den Perspektivenwechsel. So wird analytisches Denken und effizienzorientiertes Handeln außer Kraft gesetzt. Im künstlerischen, zweckfreien Spielen kommen bisher unbekannte Potenziale und Eingebungen in die Sichtbarkeit. 

 

Wenn wir verstehen, warum wir uns in unserem strukturierten Handeln zum Teil selbst blockieren, öffnen sich Freiflächen für neue Ideen. In unserem Workshop werden Anregungen gegeben, aus der Routine auszusteigen und Grenzen zu durchbrechen. Michael Evers referiert über verschiedene Themen aus Philosophie und Kunstgeschichte und führt Sie durch den kreativen Workshop. Sie lernen nicht nur neue Denkweisen kennen - gewünscht ist auch das Gespräch, der Austausch untereinander und die Entstehung neuer Netzwerke.

Concrete Textile

New INTERPRETATION OF TEXTILE CONCRETE

g.tecz sponsored university project

Mrs. Kühner, student from the Weißensee Kunsthochschule Berlin developed a new textile concrete with G.tecz's high strength concrete. Mrs. Kühne sucessfully transfered the technology into a fantastic new product. We are happy to support the project with material and know-how.

success story

Textilbeton ist mittlerweile als robuster Verbundwerkstoff bekannt. Aber was genau soll nun »Betontextil« sein? Das Projekt ist eine Materialstudie, die im Rahmen einer Masterarbeit im Fachgebiet Textil- und Flächen-Design der Weißensee Kunsthochschule Berlin entstand. Das Ergebnis ist erstaunlich einfach: Textilbeton sieht aus wie Beton, Betontextil erscheint in textiler Struktur.

Heat Resistant Special Concrete Molds for Aluminum Casting, developed by G.tecz.

Concrete Molds for Liquid Metals

Nano optimized concrete matrix systems are enabling new solutions, not only in the building industry. G.tecz Engineering’s latest development is a high temperature resistant optimized concrete matrix, based on Portland cement in combination with other cements and high temperature resistant fines.

The material can take temperature shock loads of 900°C up to 1400°C in a short time range while keeping mechanical performance for an outstanding time span. Next to the outstanding mechanical performance and thermal resistance, the material is extremely affordable compared to industrial standard molds made of steel. Fields of applications are molds for liquid metal casting as well as chassis for high temperature ovens or heat shields of machines.

Application – The new developed concrete was tested in laboratory as well as industrial scale for aluminum casting. Industrial partners from the automotive industry proofed the concept and economical aspects of the technology. Main idea of the concrete mold is to replace steel molds for prototype developments as well as usage for zero and small series productions.

Advantages of the system are;

  • Easy to realize concrete molds due to the fluid concrete behavior due to its self leveling and doesn’t require temperature treatment for the hardening process.
  • Simple and precise form generations (olds of the molds) by 3d printing the negatives.
  • 3 times less weight compared to steel molds
  • 90 percent cost savings compared to steel molds
  • Surface near cooling or heating channels are possible and can be directly integrated in the concrete mold.
  • Usage of the mold for several cycles
  • Release agents are not necessarily required for the aluminum casting.
  • High compressive strength of the concrete is possible, up to 300Mpa.

G.tecz’s industrial partners tested the mold system with 900°C hot and fluid aluminum that was casted in the pre-heated concrete mold as well as aluminum injection molding with 800bar pressure. Both tests were successfully mastered by the concrete mold. Molds and aluminum parts were made as test elements for engines for cars. The precision of the casted aluminum elements hat been very high and tolerances were accepted.

The concrete mold technology is also interesting for small companies (SME) that are related to the liquid metal molding industry and are producing smaller aluminum elements like door or window handles, spare parts for cars, machine parts and so on. G.tecz developed a complete and simple solution: Clients can develop their products via computer aided design (CAD) and print their mold negatives with a simple 3D Printer. The printed negative is used for concrete casting – that’s it. The whole process can be done within hours, very cost effective and independent from suppliers.


Material properties can be adapted regarding project requirements. The following parameters are representative:

– Compressive strength: 190Mpa – 350 MPa

– Tensile strength (matrix): 9 – 20 MPa

– Flexural strength (matrix): 20 – 27 MPa

– Flexural strength (reinforced): 35 – 75 MPa

– Fracture energy: up to 90 kN/m

– Carbonating up to 1.0 mm after 3 years

– Chloride Diffusion not measurable

– Water resistance not measurable

– Frost-resistance < 100 g/m2

– Dispersion up to 80 cm- shrinkage: 1 – 1.5 ‰

– crack width << 0.1 mm

– Temperature resistance up to 1750 °C

– Weight: 2.4 – 2.7 t/m3

– heating rate: 1750°C within 120 sec. possible

– Thermal conductivity adjustable: 0.2 – 0.065 W/mK

 

Further applications of the heat resistant concrete are chassis of oven systems as replacement for ceramic tiles. New oven systems are heated with gas turbines and are performing a temperature difference from 20°C to 1400°C within 2 minutes only.

General oven systems with ceramic heat shields do show erosion problems after a few weeks, concrete shields don’t. Advantage of those oven systems, compared to electronic heated systems, they can be used in periods only and if required for a few hours; they don’t have to be heated over days.

Advantage of the special concrete heat shield is the high temperature resistance, the affordable price and the possibility to design the oven in a complete new design.

Secondary steel structures and constructions are not required. Because of the fluid concrete, any geometry can be realized – monolithic plug and play prefabricated oven blocs can be produced.

G.tecz is specialized in the development of cement bonded high tech materials for the industry. Tailor made economic and ecologic solutions from small series to big industrial applications. The company offers complete solutions from material development, mold and product innovations up to consultancy for setting up production lines and production facilities.

3D Druck Beton - Pilotprojekte

3DP - Additive Layer Manufacturing mit Beton - eine von G.tecz Engineering speziell entwickelte Zement gebundene Fertigmischung für Pulver verarbeitende Drucker macht dies möglich. Der nano optimierte und rein Zement gebundene Werkstoff benötigt lediglich Wasser zur Reaktion und erreicht Druckfestigkeiten von ca. 5 N/mm2 bei einem Gewicht von 2kg pro Liter. Durch seine offene Struktur eignet er sich nicht nur für den Druck von Aluminiumguss Formen sondern auch z.B. für den Druck von Designprodukten bis hin zu Repliken von Statuen oder Ornamenten zur Anwendung in der Altbausanierung. Der sandsteinartige Charakter des 3D Druck Betons kommt hierbei den architektonischen Ansprüchen entgegen.

Die Firmen Voxeljet und G.tecz Engineering sind die Entwicklungspartner des neuartigen 3D Druck Betons und suchen Interessenten für Pilotprojekte. Firmen können sich für den Pilot-Druck bewerben und an der Evaluierung des neuen Werkstoffs teilnehmen. Branchenübergreifend soll das Material sowohl für den Aluminiumguss, wie aber auch für Produkt- oder Designanwendungen im Innen- oder Außenbereich getestet werden. Engagierte, 3D Druck interessierte Firmen und die Entwicklungspartner werden in Kleinserien das Druckverfahren, das Material sowie die Druckergebnisse evaluieren. Vor Verkaufsstart können Interessenten die einmalige Chance nutzen und das Material für ihre Anwendungen einsetzen.

REAL ADDITIVE MANUFACTURING - 

23. October, 2015 - Delft University, Berlage Rooms

 

IN SEARCH FOR THE NO NONSENS APPLICATION OF 3D PRINTING IN THE BUILT ENVIRONMENT.

 

>> Additive Manufacturing (AM) is referred to as a very promissing technique. What are the important functions and characteristics of produced building components? Can additive manufactured elements already be implemented widely in the building industry, or should their performance be improved first? This Think Tank will focus on the implementation of AM in the building industry,

investigating questions regarding durability, (anisotropic) material behavior and which materials are suitable. Another ambition concerns the possibilities of combining various materials in one AM process. Are ‘new’ materials with matching production systems required? And there are more challenges to explore. During the discussion we invite you to be creative and think about the applications of AM. Let’s give the building industry a boost with Real Additive Manufacturing! <<
