An Innovative Reinforcement Approach for Rebar-Free 3D Printing of Transportation Infrastructure

The main objective of this project is to investigate an innovative configuration for a rebar-free construction 3D printing process for resilient civil infrastructure development. The proposed configuration includes using a self-reinforced printing material as well as a discontinuous vertical reinforcement technique which can be fully automated. To this aim, twisted steel fibers will be used to develop a structural self-reinforced printing material. Inserting steel mini-rods into the layers will be investigated as an additional strengthening method. These steel rods are designed to act as vertical reinforcement and to address a possible weak interlayer adhesion and its influence on the mechanical performance of 3D printed elements. This project will result in development of a fully characterized printable self-reinforced mixture as well as comprehensive experimental data on the performance of an alternative reinforcement technique under different loading conditions.
