Polymer concretes employ a polymeric binder to replace typical lime-based cements. Due to their high compressive and tensile strength, chemical resistance and fast curing time, their application vastly ranges from repair to precast components and structural elements for aggressive environments. The studied joints aim to create reversible connections between the beam elements, therefore creating rapidly assembled structures with a high degree of geometric adaptability. The geometric constraints for the production of the nodes are analysed along with the mechanical properties of the joints in order to find an optimal compromise between the structural and the fabrication requirements. The connections make use of interlocking joints which ensure an adequate force transfer between the elements. For the reinforcement of the Polymer Concrete, high-strength steel reinforcement cages were 3d-printed, taking advantage of the facilities of the Fraunhofer Institute for Production Technology (IPK) in Berlin.
