UHPC shading elements create

Ultra high performance concrete (UHPC) is somewhat “new” to the façade rainscreen marketplace. Taking advantage of various manufacturing approaches, there are a variety of UHPC or fiber concrete panels available. The ability to achieve large format sizes, as well as a large range of finishes and custom capabilities, has quickly allowed fiber concrete panels to become very popular within the rainscreen design community.

The UHPC stone veneer is a thin lightweight composite façade panel made from natural stone veneer backed with ultra-high performance concrete. This stone-faced precast solution is creating a new future for prefabricated architecture, by creating classic, stone looking facades that are lightweight, making it easier to use on buildings.

Ae-uhpc, coarse aggregate UHPC product, expansion ≥ 600mm, 1-day compressive strength ≥ 90Mpa, 7-day compressive strength ≥ 150MPa, breaking the technical monopoly of SBT.
