A difference in the definition of UHPC is always a difference in quality

The American Federal Highway Administration (FHWA) defines UHPC as follows:

UHPC is a fiber reinforced, portland cement based product. Through the appropriate combination of advantagements in superplasticizers, dry constituent gradiation, fibre reinforcments and supplemental cementitious materials.

UHPC is a cementitious composite material
composed of an optimized gradation of granular
constituents, a water-to-cementitious materials 
ratio less than 0,25 and a high percentage of 
discontinuous internal fiber reinforcement.

The mechanical properties of UHPC include  
compressive strength greater than 150 MPa
and sustained post-cracking tensile strength
geater than 5 MPa.

We define our UHPC grades as Ultra High Performance Concrete but without steel fiber reinforcement.
For all our UHPC grades, whether cast, mortar or spray, we achieve the technical values without the addition of any fibers.

UHPC is a cementitious composite material composed of an optimized gradation of granular constituents, a water-to-cementitious materials ratio less than 0,20 and no procentage of internal fiber reinforcement.

The mechanical properties (without fiber reinforcement) of UHPC include minimum 
compressive strength of 150 MPa (up to 
260 MPa and more) and a minimum tensile 
strength 15 MPa (up to 30 MPa and more).

We achieve 70% of the maximum nominal 
strengths after 48 hours and not 28 days.

Of course, fibers of all possible qualities and
geometries, steel reinforcements and a wide
variety of aggregates can be added to the
UHPC concrete.
On our website you will find a long list of
these materials that we have been using for
over 20 years.
But if we want to compare material with
material fairly, we have to compare the
base with each other and that means the
pure UHPC binder without fibers and
reinforcements.

A difference in the definition of UHPC is 
always a difference in quality.
