Dynamics of capillary water absorption in natural stone

Two natural carbonate stones from Croatia (Kirmenjak avorio and Veselje unito) were analyzed to assess their properties for use in masonry buildings. The results indicated considerable differences in the water absorption (expressed in g/m2) shown as a function of elapsed time. Testing was performed by the method specified in European standard EN 1925:1999 accepted in the European Union and in Croatia. During the petrographic analyses, different characteristics important for the absorption of water in natural stone, were highlighted, especially those which were relevant to its composition, structure, texture and pore system. The importance of assessing the movement of water in the stone relative to its bedding and the construction in which it will be placed is emphasized.
