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

UHPC Informationen für Leute aus dem Ruhrpott (nicht ganz ernst gemeint)
An unusual bond and impact test with UHPC mortar
An unusual bond and impact test with UHPC mortar
This test was carried out by us more than 15 years ago. The aim was to test the adhesion of UHPC mortar in a pipe section. For this purpose, a pipe section was provided with only a few small anchors.
Only half the circumference of the pipe section was lined with UHPC mortar in a layer thickness of 25 mm / 1 inch. The half-circumference lining was chosen to increase the load in the event of an impact.
As you can clearly see in this video, the adhesive force of UHPC mortar is so great that it took several impacts and a deformation of the steel structure to release the UHPC mortar lining from the steel structure.
Recycling of UHPC concrete compared to standard concrete
make them a competitive material for steel. Also in this comparison, UHPC concretes have advantages such as corrosion resistance and temperature resistance, etc.
UHPC concrete constructions achieve a multiple service life of standard concrete in comparable constructions. This means standard concrete structures are demolished much faster and the debris has to be recycled. The demolition material is used as gravel. It is currently trying to recycle this demolition material as a building material.
In addition to a longer service life compared to standard concrete, UHPC also has many advantages here.
1. UHPC concrete has a very high compressive strength which is similar or better to many standard aggregates of standard concrete.
2. UHPC concrete granules have no to extremely low porosity. Thus, UHPC Granules does not absorb very little water.
4. UHPC concrete granules are corrosion and seawater resistant. UHPC concrete granules can be easily processed with standard concrete or UHPC concrete.
6. At the moment we are working on trying to prepare standard concrete material granulate, so that it can be used as a fine aggregate for some UHPC grades.
7. We also plan to use recycled UHPC high temperature material. It could very well be used as aggregate for UHPC HT or for refractory materials.
Short time repair story of a oil rig with UHPC
massive corrosion on some columns, the entire statics of the conveyor station was endangered. It was expected that they have to give up the station in a short term.
The only technically feasible solution that offered itself at short notice was the filling of the columns with UHPC concrete. A demand of approx. 600 tons of UHPC material was determined by the oil company. Within a week, the 600 tons could be produced.
The procurement of raw materials was the time factor here. The actual production did not take more than 1.5 days.
There was no time to ship the UHPC material to the Bay of Bengal. The oil company rented Anotonow AN 124 aircraft for direct transport.
On site, a ship was chartered for the material and the mixing systems. On the ship, the UHPC material was mixed by specialists and pumped into the columns.
What were the reasons why the oil company chose UHPC?
1. The fast availability
2. The fast strength development
3. The absolute sea water / corrosion resistance
4. The fast processing, even on the high seas
5. A long-term technical solution
New use of recycled windmill rotor blades as aggregate for UHPC concrete
UHPC grouting material is used worldwide in the
in the offshore and onshore industry worldwide for more than 25 years.Mostly, UHPC Grout has been used to make transition pieces and foundation systems for wind energy, oil production, tidal power plants and floating windmill platforms. There are also plans to use UHPC concrete as corrosion protection for the systems in these areas. It would be a safe, easy to install, cost effective and durable solution. Another development for the future is the combination of UHPC concrete and recycled rotor blade material. Several thousand used rotor blades from offshore and onshore wind turbines are lying on the ground around the world to be recycled or disposed of. Storage has become a very big problem in some countries. In many industrial
applications we use glassglass fibres, carbon fibres or plastic fibres asaggregates to our UHPC concrete.
In order to carry out reuse, recycling and upcycling as standard in the near future, special UHPC concretes are the ideal combination partner. It should also be possible to add construction material from wind turbines to our UHPC with appropriate processing. This could then possibly be used again as foundation material for new onshore or offshore wind turbine.
