Fig. 11From: Taya Caves, a Buddhist marvel hidden in underground Japan: stone properties, deterioration, and environmental settingPhysical interaction of Taya stone with water: representative trends of mass change by water absorption in total immersion at atmospheric pressure and by hygroscopic water adsorption/desorption in the shaded RH range (upper box); slake durability, determined in total immersion in water by the jar slake test (lower box). When differentiating between the brown and grey rock facies, the 2 different colors are used in the graphsBack to article page
