Sažetak
The research presents results of water absorption determination of natural stone samples by capillarity.
Two Croatian natural stone carbonate varieties were analysed for this paper, Kanfanar from quarry in Istria and Seget from quarry near Trogir. Natural stone Kanfanar (Istrian Yellow) is tawny colour limestone petrographically defined as stylolitised oncoid floatstone.
Natural stone Seget is limestone from homogenous to microbeded structure with visible pores, white to yellow in colour. In some parts it has stripes in bluish tone consist of bioclasts.
Analysed samples of domestic (Croatian) natural stone varieties show considerable differences in water absorption (expressed in g/m2) showed as a function of square root of time expressed in seconds (s0,5) or as a function of elapsed time in minutes.
Testing was performed by method specified in European standard EN 1925:1999 accepted in European Union and in Croatia. Gained results shown in this article could be very useful during in-building, especially concerning the various orientations of stone elements in different stone construction. That could decrease the negative influence of different factors during the stone decay especially in wet conditions.
