Drying of brick as a function of heat flows and analysis of moisture and temperature distributions

In order to investigate the driving mechanisms for frost damages in brickwork, laboratory tests has been performed on a test brick wall. These test include monitoring of temperature and moisture distribution in the wall as function of the influence of driving rain, wind speed and solar radiation. After the initial tests the surface of the wall was treated with mortar and a new series of test was performed.

The wall with and without treatment performed almost equal during the influence of driving rain, and during the later drying phase, the difference was equally small.
