Recycling of old building materials with HPc and UHPC bindersystems
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

We reduced the temperature for the steel
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
wear-resistant than refractory concrete, which
has resulted in a significantly longer service life
UHPC Concrete is an ideal material for tactile design
UHPC can push model technology to its limits. Because only the quality of the model construction limits the possibilities of UHPC concrete.
- 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
- 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.
UHPC Security projects in south of Europe
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
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,
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
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
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
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
UHPC technology mixing and applying UHPC under normal
conditions and under extreme conditions.

UHPC Wear protection for an ore pallet plant in Bahrain
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.

UHPC Wear- and corrosion protection for all pipe dimensions
out was one of our first major projects more
than 25 years ago. The pipes should be
permanently protected against wear and
corrosion with UHPC under the toughest
conditions. First of all, pipes for pneumatic
material delivery lines in the cement industry
were lined. After that, pneumatic and hydraulic
pipelines for the coal-fired power plant industry
and the steel industry were lined. Later came
the offshore industry and the wastewater
industry. We lined pipes of any diameter from
40mm / 1,57inch to 8000mm / 315inch. Here,
the geometry played no major role, so
whether Y-piece, pipe bend, reducer, etc.
The huge advantage of UHPC over all liners at
that time was the seamless lining, the flexibility
in layer thicknesses, the variations in material
quality and the very high wear and corrosion
resistance for a very long service life. Even
today, pipes are in use that were lined 25 years
ago with UHPC.
Today, new pipe systems are lined with UHPC
or existing pipe systems are repaired with UHPC
material. It makes only a very small difference
whether they are concrete or steel pipes.
We use UHPC mortar, UHPC castable and
UHPC shotcrete as lining material. UHPC
Rapid material grades are used for extremely
fast repairs.
In the offshore industry, UHPC is used both
as the inner and outer lining of pipelines.
UHPC can also be used underwater. A 15mm
or 0,6inch thick UHPC coating is waterproof
and absolutely corrosion resistant. A UHPC-
lined offshore structure no longer requires
regular corrosion protection coatings. UHPC
is used today as a material for offshore
constructions and offshore foundations
worldwide.
For some years, we use high temperature resistant
UHPC material in the steel industry. Hot gas
temperatures up to more than 1000°C / 1832°F
are no problem here. We also coat hot gas pipe
system with a combination of UHPC and high
performance insulation. This makes it possible
to dispense with stainless steel as a construction
material, which in turn reduces costs enormously.
Wastewater pipelines, storm water drains, storm
water storage systems road drainage systems,
sewage systems and culverts whether made of
steel or concrete, can be easily repaired with
UHPC. It is not necessary to clean the
construction of rust before you start with the
lining. With UHPC Shotcrete, larger pipelines
can be quickly and permanently repaired. Due
to the extremely low rebound of less than 3%,
special cleaning work in the pipeline is not
necessary.
Smaller repairs can be done quickly with UHPC
mortar or UHPC Cast. As UHPC materials
exceed the compressive strength of all standard
concretes by more than once, steel and concrete
pipelines are more resilient after a complete repair.
Advantage of UHPC
Absolutely waterproof
Absolutely moisture resistant
Extremely corrosion resistant
Very high life expectancy
Very good resistance to a variety of chemicals
Very high strength
