English abstract:
By working with high performance concrete (HPC) or ultra-high performance concrete (UHPC) it is
possible to reduce the wall thicknesses of prefabricated double-wall elements to a minimum. A
disadvantage of these high performance materials is the smooth surface of the hardened concrete. As a
result, the bond between the prefabricated elements and the cast-in-situ concrete is insufficient. With this
in mind a new construction method has been developed at TU Vienna. Thanks to the arrangement of a
reinforcement mesh protruding from the precast concrete and embedded in the cast-in-place concrete, it
is possible to achieve an artificial interlock ensuring a monolithic structure. The theoretical background of
this new construction method is described in this paper. To verify the positive effects of the new
construction method, different tests have been carried out at the laboratory of the institute. This paper
contains a detailed description of the test specimens and the experimental procedure, as well as the test
results.
