UHPC materials open up completely new worlds for architects and designers.
What is the difference between UHPC and standard concrete or natural stone?
The processing
UHPC materials can be easily processed as mortar, casting mortar or sprayed material. The W/C ratio for our UHPC materials is between 0.22 and 0.17. There are no additives necessary. Special pre-cast elements of all sizes and geometries can be produced in exactly the same
way as large quantities of elements.
The design
UHPC materials can be made extremely fine. This makes it possible to replicate almost all surfaces that occur in nature exactly. Whether in large or extremely fine size. UHPC can be combined with all minerals, metals, plastics, pigments, woods, glasses, etc.
The resistance
UHPC is absolutely waterproof and vapor-proof after just a few millimeters of layer thickness. UHPC is extremely corrosion-resistant, wear-resistant and easily resists all animal attacks.
The properties
UHPC has a much higher compressive strength than very good concrete qualities. UHPC is very flowable and self-compacting in its casting version.
UHPC concrete achieves its maximum strength
within 48 hours.
The temperature resistance
UHPC in its standard version can withstand temperatures up to 450°C/842°F permanently. UHPC in its high temperature version can withstand temperatures up to over 1000°C/1832°F permanently. A normal fire even over a longer period of time can not damage a UHPC construction.Facade
Vertical and horizontal gardens can be created with UHPC facades and roof structures. The UHPC specially produced for these applications is very light, is rot-resistant, waterproof, and plant roots cannot penetrate it. It can be laid seamlessly on a flat roof. For vertical (facade) gardens, combination constructions according to the design of architects or garden designers can easily be made in any size.
The insulation
UHPC can be combined with a variety of modern
high performance insulation materials. With these
combinations, it is possible even at extreme
outdoor temperatures without great expenditure of
energy to achieve pleasant internal temperatureseasily. UHPC in this combination is extremely high energy efficient.
The security
UHPC in a certain combination of materials is extremely well burglary resistant.
Areas where UHPC offers great advantages
- Pool decks
- Curbs
- Steps
- Wall
- Concrete ramps
- Swale
- Drive ways
- Footings, foundation, slabs
- Pads, additions, floors

I live in california and we had some problems with big fires last year. You also write about fire resistance in your article. I would like to know more. Is it really like a house from this UHPC concrete would survive a fire like we had here?
ReplyDeleteYes, a standard concrete house would resist a short-term fire. A house made of high-temperature UHPC would fire with a temperature of 1200°C / 2190°F for a very long time without damage survive. The house construction is thus protected against fire from the outside. But there must be another problem solved and these are openings such as windows and doors. Even in the case of short-term fires, the window glass is thrown or the window frame melts, the same applies to doors made of wood or plastic and the fire can penetrate the house.
DeleteWe have already made lightweight and thin UHPC doors for some customers that are virtually indistinguishable from standard or designer doors. Likewise, we have already made tight closing window blinds made of UHPC concrete. The window blinds are also very lightly constructed. We work with the doors and the window blinds with several designers, also in the US together.
UHPC under fire will explode (see Spalling) if not properly added with PP fibers.
DeleteThis statement applies to standard concrete qualities but not to high-temperature resistant UHPC HT. For the production of UHPC HT material qualities, we use, among other things, a very special alumina cement. UHPC HT is permanently temperature-resistant up to 1200 ° C without chipping.
DeleteIt is interesting to see what the architects think of in terms of modern design but there must also be solutions and design for existing and new homes. I find your solutions for our housing problems interesting. I hope that more and more local construction companies will be interested in your UHPC materials as well.
