Today's
state
Today,
there are a variety of so called UHPC Ultra High Performance Concrete products available on the international market.
Every
concrete quality is described very precisely in the technical
literature. There are well defined general material tests. Every
architect and structural engineer can work with these defined values.
For more than 30 years we have been developing and producing UHPC for a variety of applications whether in architecture, offshore, security, road construction, bridge construction, tunnel construction etc.
In this long period of time, no one has succeeded in establishing a clear, worldwide definition of UHPC. It will probably never be possible.

An
explanation attempt
Ultra High Strength Concrete was
developed in 1981 with
a compressive strength of more than 120 MPa /17500 psi. Since
this newly developed binder has found a hitherto unprecedented range
of possible applications, the term Ultra High Performance
Concrete was developed. This generally used
product designation is exclusively focused on the word performance and is therefore not a technical specification.
The
word analysis
UHPC
= Ultra High Performance Concrete
Ultra
= Extreme, Special, Exceptional
High
= Very intense, Powerful, Strong
Performance
= Performance, Exercise, the act of performing, presentation, to
carry out an
action
Concrete
= Formed of concrete, a compact mass of sand, gravel, cement
and water
Elvis,
Michael Schumacher, Michael Jordan, Neil Amstrong, a 747 Jumbo Jet, a
Rolls Royce had an
Ultra High Performance, but did they perform in the same way?
No, you cannot compare them.
The
original idea of an Ultra High Strength Concrete with a
minimum compressive strength of
120 MPa / 17500 psi plays no decisive role in this performance.
The
most important characteristics of the Ultra High Performance Concrete
are made by a
special
cementitious added with mineral, metallic, organic, non-metals,
inorganic non-metallic additives
or aggregates. The water/cement ratio should be below 0,20.
The next generation of UHPC materials has already been developed and is being processed - UHPC desert sand concrete. It will no longer be necessary for some countries to destroy their rivers and beaches or to transport sand around half the planet.

We are working on a product specification that allows every customer to ensure that they get the highest quality UHPC Ultra High Performance Concrete.
