An unusual adhesion and tensile test with UHPC Cast

 An unusual adhesion and tensile test with UHPC Cast

A customer asked us to demonstrate the exceptional adhesion and tensile strength of our UHPC Cast binder. Our test idea was also unusual. For this test in our workshop we needed a Monster can, two simple rusty flat irons, some UHPC Cast binder, a few steel fibres and bigbags with different fillings.
The Monster can was cut at the top and bottom and the flat irons were put in without touching each other in the can, then the UHPC cast binder material was filled in. We left the material to harden for 24 hours.

After 24 hours a flat iron should be attached to a crane hook and at the other flat iron weights of 1to, 2to and 3 to were attached. The respective weight should hang in the crane hook for at least 2 days without releasing one of the flat iron from the UHPC.

All three weights hung a week in the crane hook without any problems.

We also did a similar experiment with polished metals. The loads were increased in these experiments to 10 to without causing damage.
