The moisture content distribution and its evolution in terms of drying
time can be comparedwith the results presented in [16] for cylindrical
samples with dimension of Ø160×100 mm. They were made of
normal strength concrete and were two years old at the beginning of
drying. For the latter the evolution of the distribution of the moisture
content, determined by gamma-ray attenuation measurements, is similar
to the one in Fig. 9b, however,with a somewhat smaller decrease of
themasswater content. The differences can be explained by the already
mentioned different mix parameters and the different definitions of the
dry reference state. The plotted distributions of the mass water content
in [16] indicate the difficulty of preserving the symmetry properties of
the test set-up in the test results.
