That was our UHPC meeting in 2019 in Houston Texas. We have been asked again and again for a further meeting in the USA since there is now an increasing demand for UHPC material of high quality for architecture, coastal protection, offshore, alternative energies and road / bridge construction.
Our partner ASANTE in Texas is responsible for planning UHPC meetings in the USA. We ask all interested parties to report to Douglas Miller.
Today, our three-day UHPC presentation in Houston
Texas ended with the hands-on presentation of
UHPC Shotcrete, UHPC Cast and UHPC / Asphalt.
All participants of the previous presentations were
particularly interested in the processing of UHPC material.
During the presentation different repair methods for bridges, concrete and asphalt pavements were discussed. Especially
the possibility of using UHPC with low pressure in the
Shotcrete process was very much in demand.
All participants expect a quick build-up of our UHPC
production in Houston.
Some participants were interested in the uses of UHPC in
boatbuilding and floating homes. Architects are planning the first
major projects for floating homes worldwide for the coming year.
The applications of our UHPC Desert sand binder and desert sand in
the fracking and oil well industry surprised almost all participants.
We would like to thank all participants for their open discussions and
suggestions. We will try to answer all requests for information and
project inquiries as soon as possible.
In particular, we would also like to thank our partner ASANTE for
their excellent cooperation in preparation and processing. Douglas
you have done a very good job.
Upon request, ASANTE and hhbc-consulting
will provide the documents for the UHPC presentation.

UHPC/Asphalt system versus concrete for pavement, industrial flooring and roads
UHPC Phalt is a grouted macadam comprising
an open graded asphalt that is flooded with high
strength microsilica based mortars. The open
graded asphalt is mixed to a design mix at a
local asphalt plant and delivered to site in tipper
trucks. It is placed via traditional paving techniques.

is 40 mm / 1,57 in). UHPC Phalt is the top layer
of the pavement that is supported by a basecourse
layer. The basecourse layer can vary dependent
on environment and loadings, internal or external
applications. Preferred basecourse materials to
support the UHPC Phalt topping are high modulus
macadam basecourse or Foamix recycled binder

Heat problems with concrete and asphalt highways
Problem asphalt roads
Asphalt streets lose their strength very quickly
as the temperature rises. Many highways, for
example, lead through desert areas in the USA
and Australia.
Driving heavy trucks in such areas push the
soft asphalt ahead or aside. The result is that
the trucks have to drive slower because of the
uneven road, which can certainly lead to
logisticalproblems and motorists who have to
drive in truck asphalt trails do not feel this as
a rest and drive slower. In residential areas,
out-of-the-way asphalt tracks cause noise
pollution as cars literally jump over these
tracks. If buses or trucks pass through these
streets, you can hold your cupboards in the
living room.
Depending on the quality of the asphalt, it is
tacky even at slightly higher temperatures and
at very high temperatures these surfaces can
neither be entered nor driven on without causing
damage.
A UHPC®-Asphalt combination can be thought
of as an asphalt matrix filled with UHPC®Ultra
High Performance Concrete. Thus, a large
proportion of this lining is UHPC® concrete,
which does not stick and temperature resistant
is well over 200°C/392°F. This combination is
still very stable even in extreme temperatures
up to 90°C/194°F in desert areas.
Problem heating asphalt roads and
adjacent houses
There is an interesting article from a company
that measured the heating of an asphalt road
andadjacent house walls in a residential area.
Then they have provided the black asphalt
pavement with a white topcoat. The road
temperatures and house wall temperatures
were measured again. The result of this
temperature measurement was much lower
than the first measurement without coating.
If the walls of houses also get a light coat the
sunshine reflection is even better. We see this
idea as a solution but not a lasting, economical
solution.
Solution heating of the asphalt surface
and adjoining houses
As for the heating of the road surface we work
with a UHPC® binder with a very high degree of
whiteness, which makes the road seem much
brighter than the standard asphalt surface. It is
used in tunnels or production halls to save energy
for lighting. Compared to the two-layer solution
standard asphalt and white coating layer, everything
is in one system and the UHPC® Phalt system is much
more durable and more economical than the
two-layer model.
Solution concrete highway
Many kilometers of roads have already been laid
with fiber-reinforced UHPC® concrete in Europe. In
addition to the extremely high strength values, which
are far above that of standard concrete, they also
achieve extremely low abrasion and are absolutely
frost and salt-resistant. The thermal stability in both
the minus and in the plus range is a lot better
compared to standard concrete. During processing,
of course, the same machines can be used as in a
standard concrete processing. Such lining is used
today on airports, highways, harbor area etc.
Solution asphalt roads
About 15 years old asphalt roads or asphalted
areas are lined with a combination system made
of asphalt and UHPC® binder. This ideal
combination of an asphalt matrix that is cast
with UHPC® Binder achieves a significantly
higher load resistance even at ground
temperatures of up to +90°C / 194°F compared
to a standard asphalt. Abrasion resistance is
much higher than standard asphalt. Such
lining is used today on airports, highways,
harbor area etc.

Concrete breakwater as a coastal defense
In recent weeks, I have met people from the Coast Guard in
some European countries. I wanted to learn more about the
current protection of coastal areas, because I think we can
work together with our experience in the application of
UHPC® (Ultra High Performance Concrete) in the offshore
industry to develop some new solutions to make our shores
safer against soil erosion, beach erosion, eroding cliffs and
shoreline erosion.

For all these structures, UHPC® can be used, directly casted or sprayed, as precast concrete elements or as a combination with asphalt as UHPC®Phalt.Many of these solutions come from the experience and applications
of our mining, road construction and offshore operations.
We use UHPC® in port areas, jetty constructions, underwater
foundations for wind turbines, tide power plants, canal locks,
sheet piling and hydroelectric power plants.

UHPC - Use in recycling plants
UHPC Ultra High Performance Concrete
application in recycling plants for
- Synthetic substance - Recycling
- Plastic - Recycling
- Military equipment - Recycling
- Paper - Recycling
- Metal - Recycling
- Precious metal - Recycling
- PCBs - Recycling
- Nuclear - Recycling
The reprocessing of paper, plastic, chemical
waste, rubber and metals has become an
extremely important commodity market for
the producing industry. Much more metal
raw material is recovered from reprocessing
than mining.
The material required for reprocessing is
stored on large exterior and interior surfaces.
Here, the bearing surfaces are mechanically
attacked as well as the corrosive liquids
extremely.
Many existing concrete surfaces show
considerable damage, which does not
guarantee the smooth and safe transport
of the stored goods for reprocessing.
UHPC floor systems are best suited for
these loads due to their hardness and
wear resistance. These floor systems are
laid without joints. Due to the very high
material density, penetration of corrosive
liquid with professional installation is
almost impossible.
UHPC floor and pavementsystems are
UHPC Phalt and UHPC TopLayer.
UHPC Phalt is a combination of traditional
asphalt with UHPC concrete. The result is a
ground or street blast with the flexibility of asphalt
and the very high compressive strength and
wear resistance of UHPC concrete. The
processing and processing time is extremely
easy and cost effective.
UHPC TopLayer are floor coverings made of
UHPC concrete for very high mechanical loads.
The material thickness is only a fraction of
standard screeds or concretes.
UHPC TopLayer are extremely corrosion
resistant and can be installed almost on any
flooring. UHPC TopLayer achieve compressive
strengths of far more than 140 MPa
Applications
- Indoor and outdoor pavements in storage areas
- Roads
- Material bunker
- Chutes
- Pneumatic transport systems
- Scrapyard pavement
- Dedusting systems
Benefits for UHPC Wear Protection
- Flexible layer thickness
- Overhead installation possible
- Jointless installation
- Extreme high compressive strength
