UHPC and color in architecture and design

We are repeatedly asked in which standard colors

we offer our UHPC material qualities and our
answer has always been the same for years:
We do not have any standard UHPC colors.

Why? There are millions of different colors
and color materials so why pick a few and ignore
the others.

Conversely, we would like to ask our customers:
What color or color effect do you want? Based
on the color specification of our customers, we
then develop a UHPC with this color specification.
 

UHPC can be used to create an infinite number

of surfaces or color structures that influence
natural or artificial light or paint. In the end, a
unique, special construction or design is created.

UHPC binders with their nanoparticles can also
have an interesting influence on the color particles
and their effects. There are also a wide variety of
pigment materials.

So why standard when you can have so much more?

UHPC Doors and gate constructions

Doors and gates to buildings have been constructed
of wood all over the world for hundreds of years. A
material that was available everywhere. There were
simple doors and gates and there were incredibly
beautiful, filigree doors and gates. There were also
doors and gates that were used exclusively for
military security and where design was absolutely
irrelevant.

Today, doors and gates in architecture are made of
light metal or plastic. In industry and in security
areas, for example, doors and gates must be fireproof,
watertight, burglar-proof, explosion-proof, etc.

The list of requirements is long

Up to now, concrete as a material for doors and gates
was only possible for safe constructions, as concrete
constructions are very heavy.
With UHPC Ultra High Performance Concrete, the
possible uses changed completely.

UHPC Concrete is an ideal material for tactile design

With UHPC Ultra High Performance Concrete, incredible structures and surface fineness can be achieved in combination with other technical advantages for the tactile design specialists or architects and designer. Since UHPC is a material from nanotechnology, the finest particles are processed here which make it possible to achieve previously unprecedented structures and you can produce these structures in large and small dimensions with a very low and simple effort.
UHPC can push model technology to its limits. Because only the quality of the model construction limits the possibilities of UHPC concrete.

Further advantages of UHPC for tactile designer are

- the extremely high strength, which makes even the finest 
  structures stable.
- the fast curing of the material with high early strength
- the very high resistance to almost all environmental conditions
- the asolute seawater resistance
- the extremely high corrosion resistance
- the very good combinability with almost all metals, minerals 
   and plastics
- desert sand UHPC concrete
- extreme white UHPC concrete

For the processing of UHPC concrete no special tools or special knowledge are required.
 
 







Exclusive hyper white UHPC binder for design

Today, the first hyper white UHPC will be
delivered to a designer. The intention is to
create exclusive design articles out of this
hyper white UHPC.

After intensive discussions with the designer,
it soon became clear to everyone that a color
pigment solution was completely undesirable.
The material should be extremely white in its
own right and at the same time have the
processing properties of our UHPC. Likewise,
the strength should be very high approx 200 MPa
29.000 psi, since it was planned to produce very
thin and very filigree design elements. The
adhesion should also be very high since it is
planned to combine gems and precious metals
with this hyper white UHPC.
We manufacture hyper white UHPC as a one-
component material, as a binder material, as a
castable binder, as a mortar binder and as a
shotcret binder

Due to these very high requirements, we have
had to create a new UHPC recipe. As raw
materials only extremely high quality white
raw materials were used and a separate small
mixing plant was installed, which mixes only
this hyper white UHPC. It took several months
for our customer to be satisfied with the purity
of the whiteness, the workmanship and the
firmness.

We would like to point out that this UHPC
material is extremely expensive compared to
standard concrete.
Even compared to our highest quality UHPCs
this special binder is very expensive. The
delivery time is longer, because the raw material
used has lead times.

This UHPC material is made only on customer
request.

Mixing UHPC Concrete - A simple process

A real UHPC (Ultra High Performance Concrete) 
consists of a maximum of three components:
  • UHPC binder
  • Water
  • Aggregates, such as quartz sand with a grain size of 0-3 mm

Nothing else is necessary. No further additives.

UHPC concrete of exceptional quality is an
easy-to-manufacture material, provided you have
the right high quality components. For more than
25 years our UHPC Mortar, UHPC Cast, and
UHPC Shotcrete have been mixed by specialists
and amateurs around the world.
 
Let's start with the most important thing, the mixer.
We need a compulsory, pan-pot or shaft mixer for
small to medium UHPC concrete volumes.
For larger UHPC concrete quantities, the use of
continuous mixer is recommended.
If you are not sure whether your mixer is suitable
for processing please contact us, we will be happy
to help you.

1st operation
Mix UHPC binders and aggregates, such as quartz
sand, in a proportion of one bag of binder (25 kg)
and one bag of quartz sand (25 kg) dry for
approx. 3 minutes.

2nd operation
Add water, add approx. 3.8 liters per 25 kg UHPC
binder and mix for at least 7 minutes.

3rd operation
Install the material. For the installation by a average
ambient temperature of 18° - 25° you have about
45 minutes time.

4th operation
Seal the newly laid surface with a suitable wax liquid
such as UHPC curing compound or a suitable foil.

That's it.

All our UHPC materials are mixed in this way. If you 
have mixed one UHPC material quality, you can mix 
all other UHPC material qualities as well. 
Simple and easy.

We also provide a detailed Mixing and processing 
manual for UHPC Cast, UHPC Mortar and UHPC
Shotcrete, with many practical tips
You can order this manual at the following e-mail address 
service@hhbc-consulting.de and 
password "UHPC mixing and application manual."

At this address, we also answer all your questions about our
UHPC technology mixing and applying UHPC under normal
conditions and under extreme conditions.

UHPC concrete for outdoor furniture

More and more manufacturers of outdoor furniture
are discovering UHPC concrete as the perfect
material for their existing furniture designs and for
completely new furniture designs that can not be
realized with standard concrete.
We deliver for each customer his special UHPC
with which he can realize his designs.
With UHPC almost all natural stones can be
reproduced and any surface design is possible.
Our customers achieve extremely fine surface
structures with our UHPC.

For our customers in the Arab countries we can
produce an extremely white UHPC.
Something very special is our desert sand UHPC.
This UHPC concrete can be made from local
desert sand and shows the local context through 
its color scheme and structure. In connection with,
for example, local wood, unique pieces are created.

For the processing you need a mixer, UHPC binder, 
water and sand (or other aggregates instead of sand), 
nothing more. Molded parts may generally be
removed from the mold in less than 24 hours.

UHPC design for Gas, Hydrogen and E- loading station

Gas, Hydrogen and E-loading stations should get a UHPC concrete design. Every future energy filling station design should be unique.

We want to get away from the standard unit sheet design. The idea is to create bold, curved, interesting roof structures, possibly greened and provided with solar panels made from our UHPC concrete. 

No armada of petrol pumps, which you will not need in the future,
but a few dispensers in combination with e-charging stations, for cars, trucks, motorcycles and e-bikes. The petrol pumps / charging stations are to get a design from historical to futuristic. In addition to a bar, would be possible, for example, a sports bar or snack bar after American Hard Rock Style or French Bisto. No supermarket where you can
chance to refuel. In addition to the bar, a workshop should be connected for special vehicle types, perhaps historic vehicle types. No mass repair, the vehicle owner may be present during the repair and possibly see from the sports bar howhis vehicle is being repaired.


Our UHPC team will create a gas stationthat is not a fast transit station, but a place to stay and meet, built with the utmost sustainability.

The first specifications are about to be completed, some architects have alreadysent their ideas and the first interested parties and investors have invited us to talks.


The gas station of today, is a dying system, which will not survive. In a very short time, there will be fewer and fewer gasoline powered vehicles in many countries. The new vehicle types will be powered by electricity or hydrogen. The gasoline powered vehicles will then be more and more vehicles, which one will call historical vehicles. These historic vehicles will, as they always do today, have their fans and drive on the streets.





Green bus roofs made of UHPC design

Insects are essential for the survival of humans and
nature. The cycle of nature would be decisively
disturbed, if not interrupted, by the death of many
species of insects.
The idea of ​​us and more and more architects was
the insects to rebuild a habitat in the cities. One
possibility is the vertical gardens or green facades.
In our opinion, quick support for the insects is the
greening of roofs of bus stops. They are small areas
but they are spread all over the city and not like a
facade in one place.
Architects find the idea incredibly good, as the bus
stops usually have a bad design. Roof greening
makes it possible to make bus stops an interesting
design element in the cities. Meanwhile, there is a
veritable ideas hype.


Why UHPC Ultra High Performance Concrete?
1. UHPC can be used to produce UHPC precast
concrete elements with a minimum thickness of
10 - 15 mm / 0.4 - 0.6 inches.

2. UHPC achieves 70% of its nominal strength
in just 48 hours, which means many advantages
for finished element production.

3. UHPC elements are absolutely corrosion
resistant

4. All design ideas can be realized with UHPC

5. Due to the low weight, the assembly can be
carried out quickly and without effort

6. Our UHPC concrete can be easily combined
with a variety of other materials such as glass,
metals and wood combined.

7. We intentionally do without the use of plastics
in our design

8. The stops can reach a lifetime of at least 60 years

9. Our UHPC is absolutely resistant to de-icing salt.

10. The bus stop area is filled with a combination
of asphalt and UHPC. This makes this area highly
wear-resistant even at temperatures up to 90°C / 194°F

Unusual material with unusual residental solutions for unusual residential areas

Unusual material

With our UHPC binder + desert sand + very little water we can produce a concrete with a compressive strength of up to 100 MPa. So better than many standard concrete qualities. UHPC desert sand concrete is completely waterproof, corrosion-resistant and rot-proof. Desert sand concrete can be easily made with most desert sands. Desert sand is currently free.

Unusual living solution
The stone system is a building system for small children. With this fantastic system, you can intuitively build without having special knowledge, that is already shown by our children.
If you enlarge this system and the stones made of UHPC desert sand concrete, you can easily build simple and, if necessary, complicated constructions quickly without blueprint and remove again. With standard concrete such stone systems are not possible because they are not sustainable enough. With the high strength UHPC desert sand concrete, even very thin-walled load-bearing stones are possible. For the production of the stones only a few different cast forms are necessary.

Unusual residential areas
UHPC building block systems can be used without any problem in all areas of the world. Due to the
large cavity volume of the stones they are extremely well insulated against cold as well as against heat. They can be used in the desert, in the damp jungle and in extremely cold environments.


Wine and UHPC - How does it work?


We were approached by an architects office if we could imagine working on a redevelopment project. In this case, it is about the renovation of a very old wine cellar. 
The cellar floor in particular is in need of refurbishment, plus a few storage foundations for large wine barrels. In some places, the floor has, among other things, moisture damage. We could make the floor permanently watertight with a few millimeters of UHPC. The new flooring should be as bright as possible and have a specific structure, which is also possible with UHPC. 
The old cellar vault also needs to be renovated in some places and the architects wants to give a very large room for wine tasting a new design. First models with UHPC / old wood combinations will be executed by us in the near future. As wooden material we use, among other things, old grapevines.

UHPC concrete and residential housing construction - infinitely new possibilities

HPC and UHPC materials open up completely new worlds for architects, designers construction companies.

What is the difference between UHPC and standard concrete or natural stone?

The material  

HPC and UHPC binder systems are based on a very low cement content. All HPC and UHPC materials
are fully recyclable and have a service life of 100+ years. It is possible to mix HPC and UHPC binder systems with recycled aggregate. With HPC and UHPC binder systems, up to 50% construction material including reinforcement can be saved due to the high strength values.

The processing
HPC and UHPC materials can be easily processed as mortar, castable or Shotcrete material. The w/c ratio for our HPC and UHPC materials is between 0.22 and 0.17. There are no additives necessary. Pre-cast elements of all sizes and geometries can be produced in exactly the same way as large quantities of elements.


The design
HPC and UHPC surfaces and structures 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. HPC and UHPC can be combined with all kind of minerals, metals, plastics, pigments, woods, glasses, etc.

The resistance
HPC and UHPC is absolutely waterproof after just less than a 1/2 inch of layer thickness. HPC and UHPC is extremely corrosion-resistant, wear-resistant and easily resists all kind of animal attacks.

The properties

HPC and UHPC has a much higher compressive strength than very good concrete qualities. HPC and UHPC is very flowable and self-compacting in its casting version. HPC and UHPC concrete achieves its maximum strength within less than 48 hours.

The heat resistance
HPC and 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, wildfire and bushfire even over a longer period of time can not damage a UHPC construction.


The facade
Vertical and horizontal gardens can be created with HPC and UHPC facades and roof structures. The HPC and 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 temperatures easily. UHPC in this combination is extremely high energy efficient. 

 

The lightweight HPC and UHPC binder
We have developed lightweight HPC and UHPC mortars, castable and sprayable concretes that offer up to 50% weight savings compared to standard concrete.


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


 


Garden-, park and costal design with UHPC


Garden and park design
From small private gardens, lakes, rivers and parks of all types and sizes, UHPC is an ideal material for nature-identical structures.

With UHPC, objects such as buildings, rocks, waterfalls, natural stones, etc. can be perfectly integrated into nature.
The benefits of UHPC for the architect and designer are
  • UHPC can be easily processed on site or as a prefabricated element of any size and geometry
  • UHPC achieves much higher strength values ​​than concrete
  • UHPC is extremely corrosion resistant
  • UHPC is water impermeable even in small material thicknesses
  • UHPC can be processed as a mortar, casting compound or as a spray mass
  • UHPC can also be processed under water
  • UHPC is absolutely seawater resistant
  • With UHPC, the finest surface textures can be achieved
  • UHPC is an ideal combination material. It can be combined with nearly all minerals, metals, glasses and plastics without problems
  • It can be achieved in constructions that are placed in nature or in water lifetimes up to 100 years.

Shore and coastal design
UHPC of the right quality withstands extreme loads from nature. In addition to the advantages
already described above, the following advantages can be added for the shore and coastal design
  • UHPC is extremely resistant to wear and impact in the right composition
  • UHPC does not lose its strength either at extremely low temperatures (-180°C / -292°F) or at extremely high temperatures (450°C / 842°F)
UHPC is much better for coastal protection and tsunami protection than standard concrete or steel.

USA - UHPC Presentation

That was our UHPC meeting in 2019 in Houston Texas. We have been asked again and again for a further meeting in the USA since there is now an increasing demand for UHPC material of high quality for architecture, coastal protection, offshore, alternative energies and road / bridge construction.
Our partner ASANTE in Texas is responsible for planning UHPC meetings in the USA. We ask all interested parties to report to Douglas Miller.


Today, our three-day UHPC presentation in Houston
Texas ended with the hands-on presentation of
UHPC Shotcrete, UHPC Cast and UHPC / Asphalt.

All participants of the previous presentations were
particularly interested in the processing of UHPC material.
During the presentation different repair methods for bridges, concrete and asphalt pavements were discussed. Especially
the possibility of using UHPC with low pressure in the
Shotcrete process was very much in demand.
All participants expect a quick build-up of our UHPC
production in Houston.

             Some participants were interested in the uses of UHPC in  
             boatbuilding and floating homes. Architects are planning the first
             major projects for floating homes worldwide for the coming year.

             The applications of our UHPC Desert sand binder and desert sand in
             the fracking and oil well industry surprised almost all participants.
             We would like to thank all participants for their open discussions and
             suggestions. We will try to answer all requests for information and
             project inquiries as soon as possible.

             In particular, we would also like to thank our partner ASANTE for
             their excellent cooperation in preparation and processing. Douglas 
                                                  you have done a very good job.

Upon request, ASANTE and hhbc-consulting
will provide the documents for the UHPC presentation.

Aggregate, fibers and reinforcements for UHPC

Over the course of more than 25 years, we have combined and applied a large number of materials with our UHPC materials. The material combination was used as wear protection material, offshore material, floor material, building material (for buildings, bridges, halls, etc.), safety technology, shipbuilding, tunnel construction, etc.
We would like to show a small selection of aggregates, fibers and reinforcements, which we have used. The aim of our development work in the combination of UHPC with other materials is the possibility to create country-specific materials with UHPC.

For each of these aggregates, fibers and reinforcements, there is a little story why we chose the combination, how we processed it and the results. if you are interested write us and we will send you this collection of little stories.

UHPC 3D printing


It is interesting to see today what printing results universities and printer manufacturers achieve.


The results are an interplay between printer technology and material technology. In my opinion today, very good results are achieved in the design areas with the printers, but many problems still have to be solved in professional architectural building construction.



There are

Compressive strength
The standard concrete reaches its maximum compressive strength after 28 days. For the printing technology unacceptable, here must be helped with accelerator. Printing speed and strength development must be matched and optimized without loss of strength.
UHPC Ultra High Performance Concrete can be a solution. Strengths of over 200 MPa can be achieved here. Already during the UHPC binder production, we can adjust the strength development, as well as the flow characteristic. The addition of commercially available additives is no longer necessary.

Print speed
Of course you want an optimum speed, you want to process a large amount / weight of concrete in a very short time. The concrete should be able to support itself after a very short time and be load-bearing for ceiling elements.
With UHPC materials, large amounts of material are already processed in a short time using the wet and dry spraying process. The consistency of the UHPC print material can be adapted to the printer characteristic. UHPC materials already develop high strength values in short time in the standard qualities. However, this time can be extremely reduced by changing material production.

Statics
The print heads are usually small in diameter and the applied wall thicknesses compared to a masonry or a finished concrete wall are very thin. Static load-bearing walls can be printed for several floors, or double-skin walls must be printed in order to achieve a structurally stable construction. Do I have to print double-shelled?

Heat / cold insulation
If I print with a standard concrete I do not achieve any insulating properties. So I have to print double-shelled and fill the cavity with insulation material or retrofit an insulating layer from the inside.
At the moment we are the only ones who are able to combine a high pressure resistant material with an insulating material. This combination material is also pumpable.

Steel girders, reinforcements
Even with 3D printing, you can not ignore reinforcements and support structures, or you can remain eternally restricted to small, simple and low-rise building constructions. How can I optimally combine carrier structures, steel reinforcements with a single printing process?

Last but not least interesting design
So far I have seen the obligatory pressure bulges on all prints. For the beginning, this may be fine but soon you should have printing technologies that ensures a sharp-edged pressure even on the wall corners. A rework of the walls in the flat areas to get is cost and time consuming. Of course, when I use the printing technology, I also want to print exceptional geometry and thin-walled constructions.

I have a note at the end
If all my misgivings can be wiped out the question remains if I want to print a large building, I need a fairly large printer technology which is not even built and dismantled and I need a very fast continuous flow of material to the printer when the printer should work quickly.

I do not want to know misunderstood. I think 3D printer technology is very interesting for the future and I know that some engineering companies are working on technical solutions. As part of our material development, we also work on a flexible, extreme fast-curing, high-compressive strength material for the printer producer. In close technical agreement with the respective printer manufacturer, we can adapt our UHPC materials to the requirements and provide test material to the printer manufacturer.
