Pipeline repair in a potash mine
Repair with UHPC wear protection systems
as the cement industry, power plant industry, steel industry and mining industry. A large part of the projects we carry out are repair orders. In recent years, the share of repair orders has risen sharply. Our customers want fast, flexible and cost-effective repairs. A decisive advantage for UHPC wear protection material is the very high protective function against wear and corrosion, the high flexibility in layer thickness and the simple. Assembly. With UHPC wear protection, existing wear protection systems can be quickly repaired. There is no need to order special plates or cylinders with long delivery times. No installation plan is requested.
We define our wear protection material for plants and floor areas. UHPc wear protection material can be processed as mortar, castable and shotcrete.

New build and repair of sewage treatment plants and sewers with UHPC concrete
to a permanent chemical and mechanical attack
by sewage from households and industry. Due
to the changing climate conditions and the resulting
extreme rain or flood masses, the systems and
channels are extremely stressed and damage that
their function is no longer guaranteed.
A material with high resistance to chemical and
mechanical attacks is necessary for the maintenance
of these systems.
This material should also be able to be processed
flexibly on site and should not require any complex
machinery.
Damage causes in a sewage treatment plant
- due to mechanical wear
- through frost and de-icing salt
- due to chemical attacks or solvents
- due to concrete corrosion in closed systems
UHPC Ultra High Performance Concrete
UHPC are special concrete products with a minimum
compressive strength of 130 MPa and a water/cement
ratio of less than 0.2.UHPC products can be used very
well for the rehabilitation of concrete - and steel structures.
UHPC products can increase to be rehabilitated
construction next to the corrosion protection even
with admixture of ceramic aggregates the static
bearing capacity.
Benefits of UHPC
- Easy installation as spray, mortar, cast
- Very high corrosion resistance
- Extremely wear-resistant
- Extreme low to no carbonation
- Usable at very high humidity
- Very high impact strength
- Extreme low chloride permeabilit
- Very high resistance to mechanical loads
- No pore formation
- Maritime and port water resistant
- Installation in the water possible
- Duration resistant
- The standard drying time is under 48 hours
- Penetrates into the smallest joints and cracks,
and closes them permanently
- Joint less installation
- Very good thermal shock resistance
- Absolutely frost and de-icing salt resistant
Machining UHPC concrete like metals
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.
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.

HPC Leight weigth and standard products systems for architecture, civil construction and design
flooring, wear protection, security product
systems, we will produce HPC product
systems for architecture, civil construction.
These products will not have the extreme strength
values like the UHPC industrial qualities but have
all the characteristic properties of a high quality
UHPC, such as verygood corrosion resistance,
high early strength development, very good flowability etc.
The new HPC product qualities are:
HPC Leicht 25 Compressive strength 20 - 25 MPa (Lightweight)
HPC Leicht 35 Compressive strength 20 - 35 MPa (Lightweight)
HPC 45 Compressive strength 45 - 50 MPa
HPC 85 Compressive strength 80 - 85 MPa
HPC 135 Compressive strength 130 - 135 MPa
We will offer these HPC qualities in various
packaging sizes, most likely from 25 kg paperbag
to 1 to big bags. We will produce these HPC
products as mortar, castable and shotcrete or as
interieur or exterior plaster.
We can offer private customers as well as
industrial customers all UHPC qualities as
pure binder material or as a mixed material
binder + aggregate.

Yearly training semiars for handling of UHPC material
The theoretical lessons taught the knowledge of the
construction site and repair methods with UHPC
materials were also trained.
At a later point in time, training in the processing
of UHPC Phalt (combination of asphalt and UHPC
binder) should be carried out.
It was the first of several seminars and training
program where we provide different UHPC
material qualities for projects free of charge and
also accompany the projects free of charge on
request.
We can also offer seminars for students, which
can then be held at the university or near to the
university.
Universities and students are welcome to contact
questions and information you may have. You can
always reach Anja at a.w@hhbc-consulting.de.

Roman roads and modern roads construction system
Old roman road |
from our office. As the name suggests, this
road was built by the Romans.
Expert estimates the completion of the road,
approximately 100 km long, in the year
200 AD. This road is about 1820 years old
and is still used as a country road today,
despite a large number of local European wars
and two world wars in these 1820 years. The
structure of this Roman road was never changed,

asphalt layer.
If we look at our "state-of-the-art" roads in
most countries of the world today, it can
easily be said that none of these roads will
last for a century. In many cities, the
pavement lasts less than 10 years and in
some highly developed countries of the
world, the pavement lasts less than a year.
Sad but true.
What was important for these Roman streets?
It was the underground structure and the road
surfaces that have survived these roads for so
long. The Romans already knew concrete, but
not only as a road surface, but also as part of
the underground structure.
Roman road today |
high quality road surface, modern roads cannot
get better but only worse than the Roman roads.
UHPC road surfaces, whether as UHPC concrete
or as UHPC Phalt surfaces, are extremely resistant
and are far superior to all previous road surfaces,
but they still need a correct, stable substructure.
This quality underground structure is particularly
Modern road structure |
important for industrial roads and industrial storage
areas.
The interesting thing is that the layer thickness of
a modern, efficient road construction corresponds
in its total layer thickness to that of Roman roads.
