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...
