The time domain reflectometry (TDR) method is commonly used for the measurement of
moisture content in soil science. In this study, the method is employed for the
measurement of moisture profiles in building materials. The practical applications
of the method are presented on an example of water penetration into cellular
concrete (aerated autoclaved concrete) samples. The measured results are then used
for the determination of moisture diffusivity as a function of moisture content.
