In the Laboratory of Building Materials, VSB-Technical
University of Ostrava, it was performed experimental
verification, which should confirm pertinence of this
system for hydration temperature measurement in the
concrete mixture. For higher hydration temperature of
concrete mixture it was chosen girder with greater sizes
150150600 mm. The concrete mixture used in the
manufacture of the measured test sample and the others
comparative samples must allow for equal distribution of
all ingredients inside concrete mixture even through
optical fibers inserted into a mold (Fig. 2).
