Abstract :One of the main deterioration factors of natural building stones is the presence of liquids entering the material. The most common mechanism of liquid ingress into building stones is capillary water absorption. It is necessary to know the capillary water absorption capacity, an important hygrothermal material feature for the deterioration of building stones. For this purpose, the effects of 5 different water temperatures insert ignore into journalissuearticles values(22, 30, 40, 50, and 60 oC); in both water and salty insert ignore into journalissuearticles values(NaCl); water in Ayazini tuff and İscehisar andesite were investigated. At the end of 2880 min, at 22 oC, Ayazini tuff absorbed 10.47% more capillary water in salty water than in water and 6.46% more capillary water at 30 oC. It was calculated that when the water temperature rises to 40 oC, it absorbs capillary water at 7.18%, 3.22% at 50 oC, and 3.86% at 60 oC. In the İscehisar andesite at the end of 2880 min, salty water absorbed 36.70% more capillary water at 22 oC and 57.21% more at 30 oC than water. It absorbed capillary water 27.42% at 40 oC, 20.84% at 50 oC, and 10.85% at 60 oC. In terms of salty water absorption rate, it has been determined that the water absorption amount decreases if the water temperature rises to 50 and 60 oC.
