A small closure joint ready for UHPC reinforced with Type X Hiper Fiber. These really small closure pours are arguably one of the most...

For the most part, steel fibers live an easy life in UHPC. Their services become needed only when cracking starts. They get stressed...

UHPC is ultra-interesting. In a previous post, we questioned why UHPC, which is more ductile than concrete, leads to less ductility at...

A cool picture of light reflecting off the surface striations of HiPer steel fibers.

Beautiful multiple cracking (at least ten hairline cracks on each side) surrounding the localization zone in a flexural UHPC sample. The...

Steel wire from which HiPer steel fibers are manufactured. Due to innovations in manufacturing, HiPer steel fibers are not only highly...

We're seeing a surge in university research on 3D printing of UHPC. In the past month we sent out fibers with lengths of 4 mm, 5 mm, 6...

HiPer steel fibers glittering and gleaming as they are added to a 4 cubic yard UHPC truck mix made from off the shelf products.

A UHPC tension impact experiment at a strain rate of 150/sec (approaching blast rate) recorded at the rate of 1,000,000 exposures per...

Ultrashort Type X HiPer steel fibers (3.5 mm to 6.5 mm) are in great demand for 3D UHPC printing applications. The unique surface...

Mockup for reinforcing a deteriorated steel web with UHPC made with Type X HiPer steel fiber. Really cool application of UHPC technology!

2023: Updating this figure with 2022 / 2023 data. It shows the number of #UHPC publications per year. The incredibly high growth trend...

We are #UHPC researchers and welcome special requests from researchers in academia and industry, in the US and around the world. Working...

The new generation of UHPC design guides (e.g. the FHWA Design Guide and upcoming AASHTO Guide) are moving away from prescriptive...

Not many people know that, unlike regular concrete, which has negligible tensile strength, UHPC's tensile capacity must be accounted for...

Have you ever seen the flexural failure mode of a UHPC beam? You might be surprised to know that it is dominated by a single localization...

The clearest sign of a maturing technology with terrific potential: movement away from prescriptive provisions towards performance criteria.

A full truck load of HiPer Type X steel fiber on its way to a precaster ... One of UHPC's most promising applications is in precast.

You think UHPC is expensive? Well, the savings you get from using it frequently outweigh the higher unit cost of the material because you...

It's finally here! From the unanimous vote during the May 2023 meeting in Kansas City, MO, to publication in March 2024, publication of...
