ABSTRACT
The research project ‘C3 – Carbon Concrete Composite’ is focusing on the use of carbon fiber reinforced plastics (CFRP) as reinforcement in concrete elements. One of the subprojects mainly targets demolition and separation of the composite as well as the reuse of CFRP’s. The scope of the project is to analyze the impact of CFRP on production processes in a precast factory, on drilling and cutting technologies and on demolition processes. To reach these goals, large scale experiments were carried out. Cutting and drilling technologies were applied and documented. Afterwards the elements were demolished and the material was crushed and went through separation processes. It was observed, that processing the composite can be carried out with reduced wear of the tools and in a shorter time frame in comparison to steel reinforced concrete structures. Furthermore it was discovered, that special techniques have to be used for the separation.
