The practical proof of the suitability of the newly developed nozzle tool for the production of reinforced and non-reinforced extrudates and sprayed layers is based on pressure, flexural and tensile adhesion tests. The samples with the designation ”M” are characterized by the fact, that the concrete was taken directly from the concrete mixer. The samples with ”S” and ”E” were s prayed or e xtruded directly into the corresponding mould. The samples marked “X”, “Y”, “Z” depict the direction of loading in the coordinate space. The following figure 5 summarizes the compressive strength results.
