UHPC Concrete for process temperatures up to 1200°C / 2192°F

UHPC is a ultra high-strength concrete with
compressive strengths of well over 250 MPa.
We are the only one producers in the world who
offer special UHPC Ultra High Performance
Concrete binders for continuous temperatures
up to 1200°C / 2192°F.
We producing and using such high temperature
solid UHPC materials for more than 25 years.
We produce UHPC HT for processing as
mortar, casting material or as shotcrete. The
processing of UHPC HT masses is almost
identical to that of standard concrete masses.

UHPC HT compounds can be processed in
combination with various high temperature
resistant aggregates or in combination with
insulating materials.
Such a combination system can protect your
production equipment or construction against
extreme heat, wear and corrosion attack.
UHPC HT and a thermal insulation layer can
reduce the layer thickness and the material
weight by more than 50% compared to
refractory concrete. Temper work as with
refractory concrete is not necessary, which in
turn reduces energy costs and installation time.
UHPC HT materials are used in new construction
projects as well as in refurbishment projects
of existing constructions.

When steel constructions are exposed to extreme
temperatures due to fires, they quickly lose their
strength or bearing capacity and dangerous
situations can arise. Construction made of
high-temperature resistant UHPC HT lose only
a small amount of strength and thus load capacity.

Especially in the construction of buildings, the
use of load bearing elements made of high temperature
resistant UHPC HT could increase safety many
times over.
It could give firefighters time to fight the fire
successfully without the danger of building collapse.

Thermal shock resistant of UHPC material

Container with liquid nitrogen

We wanted to know how good UHPC Ultra
High Performance Concrete is at extreme
fast temperature changes.
We casted ten UHPC concrete plates with a
thickness of 25 mm /1 inch. The plates were
dried for 48 hours at room temperature
(20°C / 68°F).
No reinforcement was used.

The plates were cooled down from about
+20°C/68°F room temperature in a container
with liquid nitrogen (-180°C/-292°F ).
We waited until the plates were completely
cooled. All plates showed no cracking after
removing them from the nitrogen tank.
We immediately heated the plates with a
burner within 5 - 6 minutes to +250°C/482°F.

Even with this alternating load, there were no
cracks visible.
For the test we used a our standard UHPC
Cast material with quarz 1-3 mm sand as
aggregate.

UHPC Concrete Design

UHPC Ultra High Performance Concrete offers designers
and artists completely new ways of designing. Whether as
pure Binder or in connection with metal, fiber or textile
reinforcement there are no limits to the creative and
constructive imagination.

In addition there is a very simple processing whether as
Mortar, castable or shotcrete. Everyone can process our
UHPC material. We can change the UHPC mortar
material structure depending on the customer's
requirements, whether as a fine clay structure or coarse
clay structure or plaster structure.
Your sculptures or constructions are resistant to even
the most difficult environmental conditions.
UHPC can also be processed under water and is
absolutely waterproof from a layer thickness of 10 mm.

Here, the size of the design pieces plays no essential
role. We have produced designs in sizes from 10 mm
to 5 meters.

The advantage for designers

• Thin, delicate structures of high strength
• Large manufactured elements in a cast thin-layer constructions.
• UHPC can be combined in a new way with almost any material (glass, wood, minerals, metals, plastics, etc.)

UHPC Applications for the Offshore Windmill Technology

Monopiles

75% of the capacity installed or under construction offshore is based on the monopile concept UHPC concrete.
Whereby transition pieces are grouted to piles by applying a monopile foundation consists of a steel pile driven into the seabed and a transition piece slid onto or into the pile. After adjustment of the verticality of the transition piece, the space between pile and transition piece is grouted with UHPC concrete which is mixed and pumped through flexible hoses into the annulus.

Tripile

A Tripile foundation consists of three steel piles driven into the seabed after which a three-legged transition piece structure is slid into the three piles. The overlaps between piles and transition piece are grouted with UHPC concrete.
The UHPC concrete connections evenly distribute the forces from the three-legged transition piece to the piles.

Tripod

A Tripod support structure/foundation is secured in place by driving three piles into the seabed through a sleeve in each of the three corners.
UHPC concrete is pumped into the annuli between pile and sleeve to ensure a strong and durable connection.

Jacket

Jacket foundations are secured to the seabed by four piles placed in a sleeve in each corner and driven into the seabed.
A strong, cost-effective connection between pile and jacket substructure is ensured using UHPC concrete.

UHPC for military use

Safeguards whether for civilian or military objects to protect against bombings, terrorist or military attacks are always current.

We distinguish in stationary safeguards such as airfields, messages, data centers, headquarters, supply centers, etc., and mobile systems for protecting people, military equipment we e.g. properties, observation posts, etc. in international use.

Due to their unique properties UHPC Ultra High Performance Concrete can hereby assume a large part of these tasks. UHPC concrete can be combined with virtually all materials. From these combinations, we can create unique technically properties.

A little story from the past

Many years ago it was asked if we could cover the floor of a barracks with UHPC, because we would have a "super concrete". The local situation was that due to the movement of the tank tracks, the standard concrete was nearly crushed in a short time and it can always be repaired, which were crushed even faster. So that the floor area holds at least a while, the steel chains of the tanks were exchanged for tank tracks with a hard rubber coating.
The damaged floor area was jointlessly grouted with a UHPC soil material of the hardest grade in a special process. After two days, the tanks could roll again.
After several months, I asked if the commander are now satisfied that they no longer need to change the tank tracks. Surprisingly, the commander was not satisfied. He found out that he has been driving very hard on the new lined area, that causes the tank tracks to wear very quickly because now the ground is harder than the tank tracks. Now he has to go back to the tanktracks with hard rubber.
We were just too good.


Advantages:

• Extreme high compressive strength 200 – 300 MPa (29000 - 43500 psi)
• In conjunction with intelligent reinforcement, the strength can be increased many times over.
• UHPC constructions are able to absorbs heavy blasts
• UHPC structures with the same wall thicknesses than standard concrete can give 4 times more security
• UHPC have extremely high early strengths compare to standard concrete
• UHPC is high temperature resistant, up to 1.200°C/2192°F
• Seawater resistant
• Precasted constructions with very high dimensional accuracy
• Significant improve resistant to penetration from high velocity fragments
• High wear and corrosion protection

UHPC perfect construction and filling material for bank vaults and strong rooms

There are still many manufacturers claiming 

their moveable safes are absolutely 

burglar-proof, that's wrong.

Everyone and I mean it really every moveable

safe can be opened with the right tools and 

enough time. There is nothing absolutely safe. 

Depending on the security level of the vault, 

burglars may require a short or a lot of time 

to open the vault and may require special 

tools.

 

The simple safe is usually made of sheet steel.

The steel of the safe construction may have 

different wall thicknesses depending on the 

manufacturer and it can also be used depending 

on the manufacturer not only one sheet but 

several layers of different steel grades.

An increase in safety is a sheet metal wall 

construction that can be filled with standard 

concrete, for example.

A further increase in safety is the backfilling 

of a safe construction in conjunction with a 

special reinforcement, which can vary from 

safe vault to vault manufacturer. Everyone 

has their special technique.

Likewise, the sheet metal construction can be 

filled with pre-casted concrete slabs of varying 

thickness and quality

Large safes such as bank safes are shed locally. 

With this type of vault there is no sheet metal 

construction, here a modern formwork technique 

is used.The wall thicknesses of such constructions 

can be several meters. In this formwork, a very 

complex and special reinforcement system is used.

In addition to the pure mechanical burglary problem

also a security against fire is required.

For high temperatures, suitable thermal insulating 

materials or, in the simplest case, air gaps in the 

wall construction are generally used to protect 

documents, pictures, jewlery, money, etc. in the 

safe construction.

UHPC Ultra High Performance Concrete

UHPC cast binders are extremely fine, have 

exceptional flow properties and are self-compacting, 

allowing much more effective reinforcement systems 

to be used compared to standard cement binders.

Our UHPC safety binders achieve compressive 

strengths of 150 - 250 MPa / 22000 - 36000 psi.

Decades of experience in wear and security

technology make our UHPC concrete systems

extremely wear resistant and very resistant to

impact. By mixing in additional aggregates, a

very resistant cast concrete with a 

multitude of burglary-resistant properties can be 

produced.

If a very high temperature resistance is required, we 

can withstand with our HT high temperature resistant 

UHPC cast binder system temperatures up to 

1200°C / 2192°F permanently. The strength values of 

the UHPC cast binder are only slightly reduced.

In large safes for banks, for example, UHPC cast 

binder offers not only high safety features, but also 

very good flow and pumping properties. The setting 

temperature of our UHPC cast products is much 

lower than for standard heavy concrete.

UHPC security panels as pre-cast panel elements 

for ATMs, server rooms, security rooms, these 

panels can be produced quickly and with great 

precision. Depending on the required safety standard, 

the panels can withstand mechanical loads or thermal 

loads or a combination of both loads. Here, the 

subsequent installation in existing houses, apartments, 

offices, etc., the mechanical loads, size of the rooms, 

as well as a weight optimization of the room design 

can be considered.

For hurricane, wild fire and flood-proof constructions 

in the interior and exterior, UHPC prefabricated 

elements allow a variety of design variations.

All our UHPC security and protection products are 

designed for private individuals as well as industry, 

military, banks, hospitals, server center, nuclear 

power plants, prison, etc.

UHPC Flooring systems for the heavy duty industry

For more than 25 years, UHPC TopLayer and 
UHPC Phalt materials have been produced and 
used worldwide in a wide variety of industrial sectors.
We do not see UHPC TopLayer or UHPC Phalt as an 
alternative to normal road or industrial floor coverings, 
UHPC material is used where these normal road 
coverings and pavements meet their load limits.

That can be at
- Extreme temperature stresses
- Very high point / pressure loads
- Very high wear and impact
- Chemical / corrosive attac
- Extreme environmental stress


UHPC TopLayer

UHPC TopLayer is a fiber reinforced UHPC concrete
product with a compressive strength of
125 MPa - 250 MPa or /17400 psi – 36250 psi
after a curing time of 24 hours.
The standard lining thickness is 25 – 50 mm or
1 inch - 2 inch

Advantages
- Fast development of compressive strength
- High wear and impact resistant
- High compressive strength
- Absolute frost and thaw resistant

- Impermeable to fluids but still vapor permeable
- Anticorrosive features
- Good bonding to sub-bases, aggregates and
   reinforcement
- High temperature resistant, in our UHPC HT
   version we can allow max. temperature of 1000°C/ 1830°F
- Jointless lining
- TopLayer surfaces require no sealing for
   industrial applications.
- Fast curing
- Sort repair stops

UHPC TopLayer can be processed and installed with standard road construction processing machines.


UHPC Phalt

Is a joint-free semi-rigid top layer. It combines the extremely
high compressive strength of UHPC Phalt mortar
with the flexibility of an asphalt.
UHPC Phalt system is produced by laying an asphalt
support frame with approx. 25 - 30% cavity content,
which is poured with UHPC Phalt binder.

UHPC Phalt can be processed and installed with standard road construction processing machines.

Advantages
- Extremely good combination of strength and flexibility
- Seamless coating for interior and exterior areas
- Compared to standard road and outer linings,
   extremely high load capacity and durability
- Temperature stable from -50°C/-58°F to +90°C/194°F

- High static loads possible
- No dust generation
- High resistance to frost and de-icing salt
- Very good chemical resistance
- Very good wear resistance
- Fast installation
- UHPC Phalt surfaces require no sealing

Applications
Mines – Roads
Desert - Roads
Chemical plants – Roads, Safety areas
Refineries – Roads, Safety areas
Roads on the water on dams, jetties and bridges
Specifically, for example, steelworks, vertical
starting jets launch pads, rocket launch pads,
heavy military vehicles, etc

Repair / maintenance
In principle, all concrete floor/pavement coverings
and road surfaces can be repaired in the shortest
possible time by using UHPC TopLayer or
UHPC Phalt.
Asphalt material can be reused as an aggregate for
UHPC TopLayer material or UHPC Phalt material.
Prior to re-use, a processing test should clarify which strength values are achieved by the re-used asphalt material. With UHPC Phalt, it is also possible to fill hollow spaces very well under the asphalt layer, which has been leached out, for example, by high water. UHPC Phalt is extremely fluid and penetrates intoall cavities and cleaves and fills them.

UHPC concrete as structural construction and corrosion protection material in Offshore projects

UHPC concrete is through its properties, such as
high E-modulus, high strength, and low
permeability excellent for rehabilitation,
protection and strengthening of offshore structures.

The splash zone is without doubt one of the more
aggressive environment for wood, concrete and/or
steel. Here you have the movement of the water
inducing wear on the structures, high level of
 oxygen inducing a perfect corrosive environment.
In salt water chlorides are present all over but
combined with good access of oxygenthis zone is
where the problem is.
 In icy regions ice sliding by
a structure will tear and wear the structure. UHPC
is here an ideal protection layer.


Splash zone protection is in general made on pillars
standing in water, and is made by creating a mold
around the pillar and cast the UHPC into the
mold.
When the UHPC has set the mold can be removed.

In case of wood pillars wood will usually rot over
time, leading to insufficient load bearing capacity of
the pillars. A mold can be placed around the pillar
and a UHPC pillar is created by casting.



Oil and gas platforms

When oil is pumped out of the ground the buttom

of the ocean will sink, which means that the
platform itself will sink slowly. As the ocean will
cover more and more of the legs of the platform
the wave forces influencing the platform will
increase over time. Eventually the strength of the
platform is not high enough to sustain heavy
storms.
 The strengthening of the platform is done
by filling the legs or part thereof with UHPC. This
will stiffen the structure and increase the strength
of this. By special engineering it is possible only
to fill part of legs, ie areas of the connections of
the steel.


Harbour fronts


Harbour fronts, piers and jetties are usually
subjected to splash zone issues a long with the
occasional impact by ships.
Splash zone issues being hammered with ice
and debris and of course the corrosion from salt,
water and oxygen.
 UHPC has the necessary
strength and impact resistance to withstand these
forces and the impermeability of the UHPC
prevents chlorides, water and oxygen in
penetration the protection layer which makes
corrosion impossible.

UHPC Concrete for extreme facade design constructions

Today, light and very filigree facade constructions with high strength values and extreme resistance to all types of environmental influences are possible through hightech UHPC materials.

Ultra High Performance Concrete
technology makes it possible to meet almost every customer requirement with regard to the surface structure. By using white cement as one of the basic components and special color pigments, clear fine colors can be achieved. Due to UHPC technology, the surfaces have an extremely low porosity, which requires sealing only in very special cases.

With UHPC an accuracy of 0.1 mm can be achieved from the mold when using appropriate molds.
The accuracy can be increased to 0.005 mm by looping.

Requirements for facade constructions

• Very high resistance under extreme climatic conditions
• Heat resistance
• Leigh weigth construction incl insulation
• Fire proof
• All colors
• Extreme fine surface structures
• Extreme corosion resistance
• Explosion resistance
• Terrorist protection
• Surface quality
• Livetime

All our UHPC products are temperature-resistant from -80°C/-112°F to + 450°C/842°F, very good
corrosion-resistant and extremely wear-resistant.
For special fire proofed construction we can
produce and delivery high temperature resistant
(up to 1200°C/2192°F) UHPC products.


UHPC materials are achieving a very high strength (120 MPa/17400 psi - 250 MPa/36200 psi). Due to these high strength values, it is also possible to produce thin sandwich panels with a
highly efficient insulation.
Insulating panels are used in the industry for
several years. In this case, temperatures of more
than 400°C/752°F are reduced via the sandwich
plates.

Even at very high permanent temperatures,  UHPC materials do not lose their very high strength values. In the high-temperature version, UHPC can be used up to a maximum temperature of max. 1200°C/2192°F.




Due to the special ductile properties of UHPC

and special panel designs, explosive effects
and the action of hand-held firearms can be
significantly reduced.

Ultra High Performance Concrete in modern architecture

The future of architecture is designed with products like UHPC (Ultra High Performance Concrete). UHPC is a concrete material with outstanding properties compared to today's standard concrete.
With a water cement value of less than 0.2 a material quality is achieved which is unique in the world.

Compressive strength

Due to the significantly higher compressive
strength (more than three times higher than
the best standard concretes), much thinner
and more elegant load-bearing structures
are possible. Likewise, considerably higher
spans of prefabricated parts are possible.

Accuracy

Facade constructions for example can be produced in a fineness which until now was not possible with standard concrete.
The finished elements produced with UHPC casting compound do not require any or very little surface finishing. The dimensional accuracy is so exact after hardening, that it is only necessary in extreme cases of extremely high production accuracies in the hundredth of a
millimeter range.

The goal is to implement your ideas into reality. For us there are no standards, but only your ideas and requirements we will fulfill.

Do not ask what we can deliver. Tell us which ideas you to have.

Surface structures

We can produce all of our UHPC materials in a variety of colors and in the surface and the structure of natural stones such as basalt, gneiss, granite, limestone, sandstone, travertine marble similar.

The surface design can be carried out with customer requirements (for example, roughened, shape structure, sandblasted, polished). Due to the extremely fine components of UHPC, extremely fine or smooth surface structures can be produced. Only the quality of the mold limits fineness or smoothness.

The advantage of UHPC materials which has a 
very close resemblance to natural stone is that 
with this material a variety of geometries can 
be prepared, which can not or only with great 
effort and cost produced with natural stones.

In addition to interior and exterior design of
buildings, to UHPC material elegant, thin-walled
concrete structures and concrete structures are
ideally suited for the design of gardens, pools,
bridges, waterfalls, filligrane, on or in the sea
water.
