UHPC® Ultra High Performance Concrete - What do we understand by this and what does your customer mean?
Are you sure you do not compare oranges with bananas ????
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.

Hello Paul,
ReplyDeleteI have received information from a friendly company that also processes UHPC that you have organized your seminars or workshops for UHPC processing and application last year. Do you also plan for 2018 seminars or workshops? Do you organize them only in Germany or do you offer them in other countries?
Yes, we held two UHPC application seminars and workshops last year. We plan to hold two seminars and workshops this year due to the great interest. In the coming weeks we will also announce on this blog our planning and the priorities of the application technology and the workshop.
ReplyDeleteEveryone is invited until then to give us suggestions for focal points in the application technology and the workshop. We will try to realize as many suggestions as possible.
