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.
