Modern interior design with UHPC concrete


Modern interior design is increasingly associated
with UHPC Ultra High Performance Concrete in
hotels, restaurants, offices and homes.
Due to the enormous strength extremely fine
structures can be achieved which is not possible
with standard concretes. UHPC surfaces are virtually
poreless and can withstand even the harshest
mechanical, temperature and corrosive stresses.

Floor design
UHPC concrete floors systems are popular thanks
to the stunning contemporary finish they offer.
Available in variety of textures colours and
combination with glass, wood, minerals and metalls,
there are endless design options for floor design.
Polished concrete achieves a fantastic finish not
unlike marble, ganite sandstone etc., while etched
UHPC concrete can be used to create any desired
pattern or design on the floor similar to tiles.
Floors made in a combination of UHPC materials
and woods look noble and elegant. With UHPC
materials almost all stone structures can be
reproduced.

Wall design
UHPC concrete walls is another example of how
effective the material can be when used in interior
design. UHPC concrete walls work well in any
room, and there is a wide selection of surface
design that can be archived using various application
techniques. For example, shuttered concrete uses
moulds to create a stylish finish featuring imprint
designs that are used to resemble wood board effects
on the surface.

Countertops and counter design
A hallmark of the industrial look, UHPC concrete
countertops not only look fantastic but are
low-maintenance, durable, very hygienic and
produced custom made in any conceivable design.
They can also be treated with various colours and
finishes, while being easy to mould and shape into
the required size. UHPC countertops can be
manufactured from a plate thickness of 15 mm / 0.59 in.

Lighting
As one the more recent design trends, concrete
lighting has become massively popular in recent
years, which is little surprise when you see the
stunning aesthetics produced from this simple
yet effective use of concrete.
Minimalist in design, various light shades and
fixtures are being created from concrete moulds
 to great effect, with some of the top lighting
manufacturers looking to take advantage of this
trending design feature.
It can be achieved layer thicknesses of less than
6 mm in some designer pieces.
Completely new lamp and lighting systems with
glass fibers laid in thin-walled UHPC materials
are possible.

Furniture
While more unique than most other modern uses
of concrete, more people are looking to create
stylish design features through concrete furniture.
UHPC concrete allows infinite variations in
furniture, such as armchairs, tables, lamps, chairs,
in terms of design, size, colors, fineness of structure,
surface and enormous strength. The same diversity
also applies to the ability to be combined with
other materials such as precious woods, glass,
minerals, metals, etc.
The demands on concrete materials in the interior
sector are several times higher than in architecture.
This is mostly about milimeter work. UHPC
castings achieve an extremely low tolerance of
just a few tenths of a millimeter out of the mold.
In most cases, post-processing is no longer necessary.

We do not compare UHPC with standard concrete
design of conventional brands. UHPC is much
more than just concrete. UHPC materials are noble
in design, are light in weight, can withstand the
toughest demands such as hot pots and cutting tools
and there are no limits in design.
Bathrooms, saunas, wellness areas, pool areas can
all be produced by UHPC concrete in a variety of
designs.

For the special and extraordinary, we offer architects,
designers and artists our UHPC desert sand concrete.
This UHPC concrete is unique. It can process natural
desert sands from different deserts.

UHPC Shotcrete system - more than 20 years in use

For large areas that are to be lined in a short time, 
UHPC Shotcrete is here a very good solution. 
UHPC Ultra High Performance Concrete qualities 
easily achieve minimum 120 MPa/1750 psi 
compressive strength.

UHPC Shotcrete material must be mixed before 

actually spraying. It is importance for the quality of 
UHPC Shotcrete that the amount of water is kept 
very precisely. Too much water reduces the material 
quality to a decisive extent. UHPC Shotcrete is using
a water/cement ratio of 0,2.
Our UHPC Shotcrete binders have a continuous 
temperature resistance up to 450°C/850°F. For 
temperatures over 450°C/850°F up to 
max. 1200°C/2200°F, we produce a UHPC HT High 
Temperature binder. The processing of the UHPC HT
version is carried out in the same way as with 
the normal temperature versions.

 

Characteristics of UHPC Shotcrete

 - No dust development, better working conditions
 - Due to the very high strength values, material
   layer thicknesses can be reduced
 - As with all other UHPC grades, a water
    impermeability is achieved from a layer
    thickness of 10 mm.
 - UHPC spray is very resistant to any corrosion
    attac
 - More constant concrete quality due to pre-
   defined water/cement content
 - Higher compressive strength with no
   fluctuations

 - Fast uniform strength development
 - Larger layer thickness due to more effective
   reaction of the additives
 - Low material rebound (below 2%)
 - Extrem good adhesion
 - Significantly larger spray performance
 - Minimal air consumption
 - Easy use of fibres
 - High security

UHPC Shotcrete in the new construction of tunnels or canals
Especially for tunnel construction, the use of UHPC
Shotcrete is an advantage. There is no need for high air
pressures like a standard shotcrete, UHPC Shotcrete is
self-compacting, the adhesive properties are extremely
good, so there is extremely little rebound and material loss.

A possible desired reworking of the surface is easily
possible without any effort. The material dust development during injection is extremely low.

UHPC shotcrete as repair material for existing tunnels or canals
Whether large or small tunnels and channel geometries whether concrete, steel or corrugated metal constructions can be repaired quickly, permanently and cost-efficiently.
Due to the fast development of strength, even larger repairs can be carried out quickly and efficiently with little machine outlay.
Due to the extremely good adhesion and corrosion resistance,
elaborate preparation is not necessary. With a simple high
pressure cleaning device, the loose particles should be
removed and then UHPC Shotcrete material can be installed.
Machines and material for minor repairs can be transported
without a problem with a normal pick-up vehicle.

UHPC HT and concrete under heavy fire

Again and again we hear of skyscrapers or facade
fires. In the rarest cases the fire is quickly and easily
extinguished.

The longer the fire lasts and the fire temperatures
reach a maximum (about 1000°C/1832°F), the
more problematic it becomes for the steel and
reinforced concrete structures, especially in older
houses that do not have the latest fire protection
technology.

Concrete can easily withstand a temperature of
300°C/572°F for a longer time. At a temperature
above 400°C/752°F, the compressive strength of
the concrete decreases. At a temperature above
600°C/1112°F, volume increases occur in reinforced
concrete, which can lead to external flaking or
cracks within the concrete structure.

The time factor is a crucial factor for the stability
of the construction.
Today we try to increase the period of the temperature
penetration of the reinforced concrete construction
by higher concrete coverings.

We developed and produce UHPC HT which has
a temperature resistance over 1000°C/1832°F. So
far, this material has been used especially in the
steel industry, but it is certainly an interesting
material for the construction industry in certain areas.

UHPC HT materials remain stronger in all
temperature ranges than those of standard concretes.

That means no matter what temperature and
burn time, UHPC HT compressive strength
far exceeds that of standard concretes.

This quality of UHPC HT could mean for the
fire fighting, that the danger of a building collapse
is reduced by a multiple.

UHPC HT concretes combine them very well
with highly efficient insolation materials. From
the experience of the steel industry we know
that we can achieve extreme temperature
reductions even in very thin wall thicknesses.

UHPC - The ultimate protective armor

The article was published under the title "smart material" in the journal economist several years ago

http://www.economist.com/node/21548918

We have more than 25 years of experience
in the development, production and application of UHPC Ultra High Performance concrete materials in hundreds of different applications, including in the military sector.

This article is already several years old. The development of UHPC Ultra High
Performance Concrete materials has been advanced since then.

Whereby in this case of application for
military bunker or shelter systems
the UHPC material is important, but also the

intelligent combination with other materials
and finally the installation of this material
combination.

With such different UHPC material
combinations, it is possible to dramatically
reduce the impact of a wide variety of
weapon systems.
With UHPC materials it is possible to
produce effective protection systems
in any climatic environments.

New construction and rehabilitation with UHPC concrete in a harbor

Ports are places to be loaded and unloaded permanently around the clock. These are general cargo, bulk goods and liquids.


UHPC concretes can be used for civil constructions and ground or road constructions. The big advantage of UHPC concretes besides the
extremely high strength values and the wear protection is the absolute
sea water resistance and a very high corrosion resistance.
These combinations of UHPC material properties is ideal for the material requirements in a harbor.


New construction and rehabilitation areas in a sea port
 
 - Jetties
 - Seawalls
 - Container terminals
 - General cargo terminals
 - Breakwater construction
 - Mole and pier construction
 - Wharf and quay construction
 - Ro/Ro terminals
 - Lo/Lo terminals
 - Bulk terminals
 - Refuelling pads
 - Indoor and outdoor storage facilities
 - Ship repair area
 - Tank area
 - Roads
 - Bridges

Benefits of using UHPC for civil construction
  • Extreme high tensile strength
  • Very good flow for casting
  • Self-compacting
  • Extreme high compressive strength
  • High impact resistance and ductility
  • Jointless surface
  • Can applied thin on even the weakest base
  • Freeze/thaw resistant
  • Fast curing time

 

Pavements and roads installation in a harbour

The activities in port areas and terminals expose
the pavements to conditions that constantly stress
of wear and tear from traffic by handling equipment.
High point loads from stacked containers and other
cargo. Rutting from continual driving along the
same routes. Impact from loading and discharging
of cargo and containers.


A combination system UHPC Phalt made by
UHPC binder and asphalt is the natural choice to
meet these challenges as it combines the flexible
and joint free asphalt with the excellent bearing
capacity and high wear resistance of concrete. It
provides a safe and efficient cargo handling, and
withstands wear on the handling equipment.

Under extreme mechanical stress, floor coverings
made of UHPC concrete have proven themselves
very well.


Benefit of using UHPC concrete for pavement and road installation
  • High wear resistant
  • High bearing capacity
  • Extreme high resistance to rutting
  • Long service life
  • Impermeable
  • Excellent resistance to thermal movements
  • Joint-free pavement
  • Semi-flexible
  • Freeze/thaw resistant
  • Swift installation
  • Early trafficking

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.)
  • With UHPC you can achieve very smooth or extremely fine surface structures
  • UHPC is significant more resistant than any standard concretes to chemical attack.

All UHPC material qualities we produce as mortar,
casting and injection molding compound.

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 protection systems are used as

Firearms 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.
