C - 26 Alternating reinforcement layout for filigree carbon concrete beams
Design and load-bearing behaviour of filigree carbon concrete beams
Unlike steel, carbon reinforcement cannot corrode, which means that components can be made thinner as only a small concrete cover is required. However, reducing the ceiling height to just a few centimetres is only a limited option for resource-efficient construction due to the associated high deformation. One solution are hollow core slabs, which require little concrete volume in the construction despite their jigh effective depth.
In this thesis, the concept of alternating reinforcement (see example: textile lattice girder) for a hexagonal girder with carbon yarns is to be implemented in collaboration with the Institute for Textile Machinery and High-Performance Textile Materials Technology. Subsequently, the load-bearing behaviour in the concreted state is to be investigated by means of a suitable test and compared with results from the literature.
The task will be specified in consultation with the student.

C - 25 Carbon-reinforced concrete under biaxial tensile load
Load-bearing and deformation behavior of carbon-reinforced concrete under biaxial tensile load
Carbon-reinforced concrete slabs show hygric and temperature-induced deformations in two perpendicular directions. These lead to biaxial stresses in the slab. If a biaxial tensile stress occurs, this results in cracks in the concrete up to yarn breakage. As a result of the interaction between the two load directions, the load-bearing and deformation behavior of carbon-reinforced concrete slabs deviates from uniaxial tensile tests.
In this thesis, slabs made of carbon-reinforced concrete are to be investigated experimentally under biaxial tensile loading. For this purpose, the results of existing research work on textile and carbon-reinforced concrete under biaxial tensile loading are first summarized and compared. Subsequently, experimental investigations on slabs made of carbon-reinforced concrete are carried out, evaluated and compared with the findings from the literature research. The aim is to characterize the load-bearing and deformation behavior of carbon-reinforced concrete under biaxial tensile loading.
The task will be specified in consultation with the student.
