UHPC - 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 products available on the market. Besides the high number of so-called UHPC products, there are just as many companies that process or distribute these products. Looking at these companies, most of the companies refer to their workforce from four manufacturers around the world, the remaining firms use standard concrete and process them in a good quality.
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.

All this does not exist in a general form for UHPC products.

An explanation attempt

An Ultra High Strength Concrete was developed in 1981 with a compressive strength of more than 120 MPa. 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 all 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 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.

Unfortunately, no generally accepted technical description of Ultra High Strength Concrete products has been agreed on worldwide, which considerably makes comparability more difficult for users.
