Fig. 1From: A laboratory experiment on salt weathering by humidity change: salt damage induced by deliquescence and hydrationExperimental design. a Humidity-change experiment. The weathering cycle was repeated 200 times. Weight, Equotip rebound value, and longitudinal wave velocity were measured every 20 cycles. b Wetting/drying experiment. The weathering cycle was repeated 20 times. Weight and Equotip rebound value were measured at the end of each weathering cycleBack to article page
