The hhbc-consulting and WPE DK Team feel responsible for
working in close
cooperation with architects,
designers, engineers, urban planners and
construction companies for a more sustainable
future.
Development of UHPC
Already during the development of UHPC Binder,
our goal is to use raw
materials that are as
environmentally friendly and energy-efficient
as
possible in production. At the suppliers of
cementitious binder systems, we pay attention to
their activities regarding environmental protection
and sustainability.
Microsilica as well as fly ash
are waste products that we reuse but they
come
from processes that consume enormous amounts
of energy. That is
why we use these products in
very controlled quantities. In some of our
UHPC
products we have been able to do without
microsilica or fly ash.
We plan to set up production facilities in Asia,
North America, South America and Africa in
order to use local resources and to limit
transport routes to a minimum.
Processing of UHPC
Our UHPC products can be mixed with 50% less
water than standard
concretes. The water cement
value in our products is 0.2 to 1.8. In some
countries of the world there is a permanent lack
of water, which is
only balanced with seawater
treatment plants that consume considerable
amounts of energy. If less water is needed for the
inforastructure,
there is more drinking water for
the people.
Only sand is required for processing our UHPC
binders to concretes with a compressive strength
above 100 MPa and no gravel.
Due to the low precast weights the energy
consumption to the transport of production to site
is much lower.
As a substitute for the admixture of sand, a wide
variety of recycled
materials can be used. Our
UHPC binder systems are ideal combination
partners.
We have developed a new UHPC binder system that
can completely
dispense with the previously
required sand and gravel qualities. Which
will
drastically reduce the depletion of sands in the river
and coastal
areas and the high-energy international
export.
In the future, we plan to drastically reduce the
production of UHPC
materials in accordance with
our quality guidelines to various countries
with
local raw materials in order to reduce the
high-energy material
transports.
Application of UHPC
Due to the high compressive strength, the component
geometries can be
selected smaller compared to
standard concretes, which leads to lower
material
consumption and thus to lower component weights.
Our UHPC materials are many times more resistant to
all environmental
influences than standard concretes.
Thus, the expected lifetime is
several times higher than
standard concrete with almost no repair.
Even today, UHPC materials can completely replace
steel constructions
in many areas and achieve a multiple
service life without corrosion
protection and repair work.
From our high-density, buoyant UHPC concretes, ships
or islands with
high load-bearing capacity and service
life can already be produced
today. UHPC materials
are absolutely resistant to seawater.
The better the concrete quality is and with UHPC concrete
it is many times better than with standard concrete, the
longer the usage phase.
