The mechanical modelling and experimental testing of concrete slabs with an internal honeycomb structure is being investigated in order to optimize corresponding construction elements in building construction. On the one hand, this is motivated by the fact that high carbon dioxide (CO2) emissions are produced during cement production for concrete. If concrete mass is saved, the associated CO2 emissions are also reduced. Weight is also saved, making the building element easier to transport and assemble.
In the panels examined here, fillers of different materiality are provided between the surface layers in order to realize the concrete savings. The concrete layer thicknesses are also to be minimized by using a textile fabric instead of conventional steel reinforcement.
The load-bearing capacity of these slabs will be mechanically modeled as well as experimentally investigated with a series of small prototypes.
