Roman roads and modern roads construction system

Old roman road
A "Römerstrasse / Roman road" runs not far
from our office. As the name suggests, this
road was built by the Romans.
Expert estimates the completion of the road,
approximately 100 km long, in the year
200 AD. This road is about 1820 years old
and is still used as a country road today,
despite a large number of local European wars
and two world wars in these 1820 years. The
structure of this Roman road was never changed,
Roman road structure
the only thing that was "modernized" was an
asphalt layer.

If we look at our "state-of-the-art" roads in
most countries of the world today, it can
easily be said that none of these roads will
last for a century. In many cities, the
pavement lasts less than 10 years and in
some highly developed countries of the
world, the pavement lasts less than a year.
Sad but true.


What was important for these Roman streets?
It was the underground structure and the road
surfaces that have survived these roads for so
long. The Romans already knew concrete, but
not only as a road surface, but also as part of
the underground structure.


Roman road today
As without a proper underground structure and
high quality road surface, modern roads cannot
get better but only worse than the Roman roads.


UHPC road surfaces, whether as UHPC concrete
or as UHPC Phalt surfaces, are extremely resistant
and are far superior to all previous road surfaces,
but they still need a correct, stable substructure.
This quality underground structure is particularly
Modern road structure

important for industrial roads and industrial storage
areas.

The interesting thing is that the layer thickness of
a modern, efficient road construction corresponds
in its total layer thickness to that of Roman roads.

Elegant and luxury design furniture made out of UHPC


More and more designers around the world
are fascinated by concrete. It is a material
that we believe is much more sustainable
than plastic and also has a much longer
service life than plastic. Concrete is easier
and more environmentally friendly to recycle
than plastic.

Concrete can be used in all climates, even the
most extreme. For some time now, experiments
with concrete have been carried out in space.
It is a possible building material for the extreme
conditions on the moon and on Mars.

The only problem for many designers and artists is the necessary wall thickness and weight. Today, furniture is thick-walled with metal reinforcement. A simple bench without a backrest for two people can weigh up to 1500 kg for some manufacturers. Many tables, chairs, etc. have an enormous weight and cannot be moved by one person. You can not say that the previous concrete furniture is gracious and elegant, it really is not. Apparently old natural stone art elements are copied with concrete today, at least that is how they look.

The architects, designers and artists may not even have the knowledge that UHPC Ultra High Performance Concrete has beenavailable to them for several decades. A concrete material that is extremely strong
and stable but also has a non-concrete flexibility. UHPC is superior to concrete in all areas.

With a UHPC material, designer furniture can be created that was previously only available in terms of wall thickness for metals and plastics.

New concrete design
The first designers are now working with UHPC desert sand concrete. Unique one-of-a-kind pieces are made with an unprocessed natural material.

UHPC design element could be sunk in the
sea and they would remain there unchanged
until the end of time.

A bench as described above would weigh less than half of concrete with UHPC.
Surfaces of outstanding fine structures can be achieved. Art objects can be produced in an unimagined richness of detail, both large and small, up to the jewelry ring on the finger in which one or more gems are
embedded.

New concrete design


Furniture could be combined with wood,
metal or glass in a new way.
UHPC is a concrete material that can be
bent in a specific construction.

Recycling of old building materials with HPc and UHPC bindersystems

In our fast-moving times, old houses, some of
them historical houses, are being brutally torn
down to make room for new, more modern,
larger, higher and often not more beautiful but
more effective new building designs. Very
often there is no time left and there is often no
will to secure the valuable and reusable old
building material.

The end of an old building is a heap of rubble
that is only suitable as gravel material for the
subbase material of streets.

The architects in particular could campaign
for the reuse of such materials. It would be
entirely possible to reuse these old materials
in modern design concepts and to save some
valuable raw materials.

This year we will start some attempts to
combine UHPC with a variety of old used
materials. We are very sure that this is
possible without any problems, both in terms
of statics and construction. Of course, with
UHPC we can copy old materials in
appearance and design extremely precisely,
in some cases this is certainly sensible and
necessary. However, we want to reuse old
materials and hand them over to a new
design function. Even building rubble could
become a very interesting concrete material
in combination with UHPC. We also want
to give architects and designers new design
options using old and ultra-modern materials.

UHPC ThermCombi lining systems

UHPC ThermCombi lining system consists of
a highly effective insulating layer and UHPC
wear protection layer

For a cement plant in Europe, we should
create a technically optimal possibility that
a complicated hot gas line is provided with
wear protection against a very abrasive
material and at the same time the gas
temperature must not drop below 700°C /
1292°F. A similar project we had years ago
for a steel plant in Asia.
In order to meet these customer requirements,
we have chosen a UHPC ThermCombi lining
system.

We reduced the temperature for the steel
structure to 80°C / 176°F. That was no problem
with the insulation material we chose. A high
temperature resistant UHPC wear protection
layer was installed on the insulation layer.

The advantage over a traditional refractory
lining is
:
 - The combination lining was about 60% lighter
      in weight than a refractory lining.
 - The total layer thickness of the combination
      lining was 400% less than that of a standard
      refractory solution.
 - This meant that the steel pipe diameter was
      much smaller than with a refractory lining
      and the supports had to carry much less weight.
 - UHPC HT wear protection can withstand
      temperatures of 1200°C / 2192°F, which was
      an additional security in this project.
 - UHPC HT wear protection is several times more
      wear-resistant than refractory concrete, which
      has resulted in a significantly longer service life
      and much less maintenance.
 
Today, the new UHPC ThermCombi systems are not only used in the steel, power plant and cement industries. The construction industry has also recognised the enormous advantages for building structures and façade constructions. It is not only the insulating properties that save energy, the significantly lower material consumption and the very light precast weight - it is especially the fire and heat resistance that makes UHPC ThermCombi building constructions very safe constructions.
 
 





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.
 
 







An unusual adhesion and tensile test with UHPC Cast

 An unusual adhesion and tensile test with UHPC Cast

A customer asked us to demonstrate the exceptional adhesion and tensile strength of our UHPC Cast binder. Our test idea was also unusual. For this test in our workshop we needed a Monster can, two simple rusty flat irons, some UHPC Cast binder, a few steel fibres and bigbags with different fillings.
The Monster can was cut at the top and bottom and the flat irons were put in without touching each other in the can, then the UHPC cast binder material was filled in. We left the material to harden for 24 hours.

After 24 hours a flat iron should be attached to a crane hook and at the other flat iron weights of 1to, 2to and 3 to were attached. The respective weight should hang in the crane hook for at least 2 days without releasing one of the flat iron from the UHPC.

All three weights hung a week in the crane hook without any problems.




We also did a similar experiment with polished metals. The loads were increased in these experiments to 10 to without causing damage.

UHPC Security projects in south of Europe

Two new UHPC security projects are
scheduled for the coming year. Both
projects are to be carried out in Europe.



The first project is a concept for securing
private property. In a former mine in the
Alps, securing rooms of the highest security
class are to be installed in former tunnels
on different levels of this mine. In order to
maintain this safety class by insurance
companies, investors have specified the
extension of the tunnels and individual
rooms using UHPC concrete.
In the first stage, about 8000 tons are to
beinstalled.



The second project also applies to the
protection of private property. In this
concept, a former military nuclear bunker
is being rebuilt. Again, most of the new
structural alterations are planned with
UHPC.
For both projects, UHPC concrete is just
one part of the backup work. We have
developed a new UHPC material quality
for both projects, which can be optimally
processed in very large quantities in both
very different locations.





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."

UHPC Wear protection for an ore pallet plant in Bahrain

We have an order to supply and install a UHPC wear protection liner in a new grinding system at an ore processing plant in Bahrain. The new grinding system was designed and delivered by a large German plant manufacturer.

UHPC wear protection was specified by this plant manufacturer as wear protection for his system.

The contract included the lining of pipelines, cyclones and separator systems. The assembly of a 25 mm / 1 inch UHPC wear protection liner with a total area of over 600 sq / 6450 sq ft was performed by a local installation company under the supervision of one of our supervisors.

24 hours after the individual plant elements were lined, they could be mounted in the ore processing plant.

WPE DK - Entwicklung, Produktion und Anwendung von UHPC Werkstoffen


 WPE-DK ist eine Gruppe von Spezialisten mit jahrzehntelanger Erfahrung in der Entwicklung, Produktion und Anwendung von "Ultrahochfesten Bindersysteme" in Deutschland und eine Vielzahl von Partner weltweit. Einige von uns waren an der UHPC-Entwicklung in Dänemark von der ersten Stunde an beteiligt.
Wir haben viele UHPC Entwicklungen und eine große Anzahl von Anwendungen in verschiedenen nationalen und internationalen Märkten initiiert und praktisch begleitet.

Durch unsere Arbeit ist UHPC für viele Anwender weltweit immer interessanter geworden und WPE-DK zu einem führenden Unternehmen für die Entwicklung, Produktion und Anwendung von sehr hochwertigen UHPC Produkten.

Wir liefern nicht Standards wir liefern Kreativität 

Wir benötigen keine Kataloge für unsere UHPC Werkstoffe unsere Firmenphiliosophie ist das erfüllen von Kundenwünschen. Suchen Sie nicht nach Katalogware und Standardprodukte, verschwenden Sie damit nicht Ihre Zeit. Nutzen Sie die Zeit Ihre besonderen Materialwünsche für Ihr besonderes Projekt zu beschreiben. Die UHPC Technologie erlaubt es uns in der Produktion UHPC Werkstoffe genau auf die Wünsche unserer Kunden anzupassen.
Standards erzeugen Standards und keine freie Kreativität in Konstruktion und Design.

Ursprünglich wurden UHPC Produkte unter dem Projektnamen „Ultra hochfeste Binder“ entwickelt, was auch der Grund für diese Entwicklung war – es solllte ein extrem druckfesten Binder für einen extrem hochfesten Beton entwickelt werden. Die Bezeichnung „Ultra hochfester Binder“ ist unserer Meinung nach eine sehr eindeutige und klare Materialbezeichnung für jedermann.

Irgendwann in der Vergangenheit ist in der technischen Literatur und an den Universitäten der Begriff „UHPC Ultra High Performance Concrete“ benutzt worden und hat insbesondere bei den Anwendern erhebliche Verwirrung gestiftet. Wie kann man den Begriff „Performance“ weltweit technisch klar und eindeutig erklären? Es funktioniert nicht - jeder versteht unter den Begriff „Performance“ etwas anderes.

Inzwischen werden zudem international in der technischen Literatur immer neue Variationen und Abkürzungen für UHPC verwendet. Praktische Anwender wie Architekten, Bauunternehmer und Designer verlieren den Überblick und den Sinn dieser Bezeichnungen.
Hier möchten wir allen Nutzern und Interessenten helfen sich in diesem Dschungel der Abkürzungen und Materialqualitäten zurechtzufinden.
Da der Begriff UHPC von DIN oder ASTM weltweit nicht eindeutig definiert ist, können heute eine Vielzahl von Materialherstellern ihre Produkte unter dem Namen UHPC vertreiben. Viele der angebotenen Produkte haben mit der ursprünglichen Idee vom „Ultra hochfesten Binder“ nur noch sehr wenig zutun.

Unsere praktischen Erfahrungen aus den letzten 30 Jahren mit hochdruckfesten Bindersystemen wollen wir weltweit jedem Anwender und Interessenten zur Verfügung stellen.

WPE DK in Dänemark ist für das Design und die Produktion von UHPC Produkte zuständig. Zudem entwickeln und konstruieren wir UHPC Produktionsanlagen für unsere internationalen Kunden.
