Luxury high end HiFi loudspeaker cabinet made of UHPC concrete

During the development and production of UHPC
material for a special machine foundation, the
extremely good damping qualities of UHPC were
discussed.
This feature is also highly appreciated by developers
and producers of high end Hi-Fi speakers.

We sat down with some of these sound aesthetes
and talked about the use of UHPC concrete in the
speaker cabinet. The discussion ended with the fact
that we started the next day with the development
of an optimal UHPC concrete for high-end 
loudspeaker cabinets.

The first achieved damping values ​​were measured
with 0.027. UHPC concrete has a high density
(up to 2900 kg/m3). The water / cement value is
sometimes less than 0.2.

The compressive strength can be chosen between 

140 and 240 MPa. The modulus of elasticity is

for the most of our UHPC products 70-80 GPa.
With UHPC Cast Binder you can cast extremely 

accurate. Only the quality of the form here limits.

With UHPC Cast we were able to offer the Hi-Fi 
and housing designer the possibility to choose any
structure and geometry. In addition, UHPC concrete
loudspeaker cabinets are shockproof and waterproof.

The UHPC showed in tests as far as we heard have
no resonance. We hope for more interests, because this
work was a lot of fun for us.

As we have heard, some Hi-Fi enthusiasts have now
made the first vinyl player for venyl records from
UHPC and are thrilled with the end results in design
and in the audio / sound result.

UHPC Doors and gate constructions

Doors and gates to buildings have been constructed
of wood all over the world for hundreds of years. A
material that was available everywhere. There were
simple doors and gates and there were incredibly
beautiful, filigree doors and gates. There were also
doors and gates that were used exclusively for
military security and where design was absolutely
irrelevant.

Today, doors and gates in architecture are made of
light metal or plastic. In industry and in security
areas, for example, doors and gates must be fireproof,
watertight, burglar-proof, explosion-proof, etc.

The list of requirements is long

Up to now, concrete as a material for doors and gates
was only possible for safe constructions, as concrete
constructions are very heavy.
With UHPC Ultra High Performance Concrete, the
possible uses changed completely.

UHPC material
 - achieves very high strengths
 - can be produced in relatively thin layers

 - is absolutely waterproof
 - is salt water resistant
 - is highly wear-resistant
 - can reach temperatures up to max. Withstand 1200°C
 - can withstand high blast pressures
 - is used in ballistics
 - can be shaped very precisely
 - can be easily combined with wood, metal, minerals and glass
 - is nanotechnology, the finest surface structures can be produced

 - enables the production of very small, fine concrete elements
 - enables large door geometries weighing several tons can be colored easily
 - is processed in a similar way to standard concrete

Machining UHPC concrete like metals

UHPC is a very unusual material that is still

far too little considered by architects and
designers. It is still viewed and processed
like a normal concrete.
Our view is more that we design and
manufacture UHPC to treat it more and more
like metal. UHPC in the right quality can
already be machined with tools from the metal
industry. Very high accuracies can be achieved
here whether in surface processing or in shape
processing.
The surface treatment can either be carried out
using special UHPC casting molds or by
identical processing steps as for metals, or
combined casting and subsequent processing.
There are no limits to the design options here.
In terms of shape, metalworking tools or machines
can be used with the same objective as metals.

Architects, designers and artists have not even
used a fraction of the technical possibilities.

One example is the use of computer-controlled
water jet cutting machines. For a customer, we
should test the possibilities of making special
bevel cuts as plate slots that cannot be cast in
this way. Additional cutting tests were carried
out to check which geometries can be cut and
what minimum wall thicknesses can be achieved
between the individual cuts. With the right
combination of UHPC binder, unit quality and
setting of the cutting machine, amazing results
can be achieved. The tested UHPC plates had a
plate thickness of 15 - 25 mm, no metallic
reinforcement and were dried for 48 hours in
normal ambient temperature before they were
processed.

With the UHPC binder-aggregate combination
used in the test, cutting distances of 5 mm could
be achieved.
As soon as possible, further cutting tests will be
carried out with UHPC desert sand binders.
Water jet cutting enables complete "images" to be cut in UHPC panels or special construction elements.
With this type of material / machine technology, it is possible to produce a large number of facade panels with an elaborate cut design at low cost in a short time.

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.
