Water absorption in porous stone materials is one of the main causes of accelerated deterioration. Consequently the water absorbing behavior (WAB) is a significant factor for the stones conservation as it determines its probability to future deterioration. Additionally, changes in the WAB can be an indication of the degree of deterioration or the effectiveness of past treatments, e.g. a water repellent treatment. For in situ measurements of the WAB currently three methods exist: Contact-sponge method, Karsten Tube and Mirowski pipe.
In this research the focus lies on the validation of in situ applicable measuring techniques for the analysis and monitoring of the WAB of porous stone materials. In previous research the performance of the different techniques was compared to the performance of the normalised capillary rise method. This indicated that the results of the different methods are related since the WAB is correlated with the internal pore structure of the porous stone material.
Currently the WAB results obtained by the different in situ measurement techniques are compared by the visualization of the WAB by time-lapse X-ray radiography at UGCT (Ghent, Belgium) and neutron radiography at the Paul Scherrer Institute (Villigen, Switzerland) and by comparison with different fysico-mathematical models describing the WAB.
