The paper presents the results of static tests of
the concrete beams exposed to the aggressive environment
in the agricultural building. The long-term effect of an
aggressive environment was expected. The aim of analysis
was to evaluate the condition of the ceiling panels. Static
tests have provided information on the possible modulus of
elasticity and the classes of concrete used to make the
beams. The concrete beams with higher structure porosity
and lower bulk density showed lower strength values and
lower modulus of elasticity values. The knowledge gained
from the analysis of beams will be used for comparison
with the results obtained from the ceiling panels
