The presented studies are preliminary investigations into the elevated-temperature resistance of 3D-printed concrete containing nanosized admixtures. In addition to material-level testing, it is recommended to conduct an experimental campaign on larger printed elements, where thermal resistance can be influenced by the structural topology.
