Özet:

Water is an important factor in the separation of natural structural stones. One of the most important mechanisms that enable water to enter the building stones is the water absorption. The capillary water absorption mechanism depends mainly on the porosite size and the geometry of the porosite system. In this study, a series of characterization studies have been carried out on the andezit, Ayazini and Seydiler weapons used as building stone around Afyonkarahisar. The petrographic-mineral characteristics of the stones (polarizing microscope, XRD, SEM), chemical, por diameter distribution and physical-mechanical characteristics are determined. Experimental studies have been carried out in order to determine the water absorption properties of stones in static, salt and acidic environments. As a result of these studies, the capillary absorption potential was between 5.83 and 6.88 kg/m2s0.5 in andezites, between 21.18 and 22.46 kg/m2s0.5 in Ayazini and between 7.05 and 9.30 kg/m2s0.5 in Seydiler. The water absorption values of most caps are measured in high acidic (pH 3) waters. Each of the three structural stones also belongs to the stones that show water absorption, because the capacity of water absorption is greater than 3,0 kg/m2s0.5.
