UHPC the future competitor of steel in many applications

We know many people think UHPC is just
a concrete, possibly a special concrete and
with this concrete you do what you just do
with concrete, nothing more. People which
think in this way, should not continue to
deal with UHPC in the future and continue
to mix their old beautiful concrete.

The philosophy of hhbc-consulting is not
the simple replacement of concrete with
UHPC. That would be like replacing gravel
with diamonds.

We use UHPC in the construction industry
where it makes sense, in very specific areas
but our real competitor market in the future
is the steel market. There are a huge number
of applications where UHPC is better, more
durable, cheaper, easier and faster to
manufacture than steel.
UHPC is corrosion and wear resistant and in a HT Version also high temperature resistant (up
to more than 1000°C).


One example of many from the past years, Rolling bearing systems
A steel mill suffered damage to several rolling bearings in the area of ​​the rolling line (the area where the hot slabs are rolled at high speed and high speed to thinner plates). These rolling
bearings are manufactured from a very special
casting. The problem was that not enough
bearing systems were available. These bearing
systems are extremely expensive and have a
very long delivery time.
In this case the steel plant would have had to
wait more than 4 months. What would mean
4 months, the rolling mill could only be used
to 30% of the capacity, a million loss.

By chance, we had heard of this problem in a
meeting for a machine floor renovation. We
looked at the drawings and specifications out
of pure interest. After a short internal
discussion, we made the following proposal
to the plant management:
We can copy the bearing completely made of UHPC. We could mix the UHPC material with graphite balls of a certain quality and size. We could achieve a high compressive strength of the material. We could process it to have similar surface roughness as the original bearing and what was extremely important we were sure to
provide such a bearing to the factory in just
four weeks.
We have provided the factory with the bearing
systems within four weeks at one sixth of the
original price. The bearings were in operation
for 5 months, by 80% of the production
capacity until they could be replaced with the
newly made cast bearings.
We have saved a lot of money for the plant
with our UHPC solution.
