An unusual bond and impact test with UHPC mortar

An unusual bond and impact test with UHPC mortar

This test was carried out by us more than 15 years ago. The aim was to test the adhesion of UHPC mortar in a pipe section. For this purpose, a pipe section was provided with only a few small anchors.


Only half the circumference of the pipe section was lined with UHPC mortar in a layer thickness of 25 mm / 1 inch. The half-circumference lining was chosen to increase the load in the event of an impact.

As you can clearly see in this video, the adhesive force of UHPC mortar is so great that it took several impacts and a deformation of the steel structure to release the UHPC mortar lining from the steel structure.
