PRRT (Partially-Rewetting Scale)

PRRT (Partially-Rewetting Scale) is a measurement tool used to assess the degree to which a surface, such as a rock or material, becomes wet or retains moisture when exposed to water or other liquids. It helps classify surfaces based on their ability to reabsorb water after drying, ranging from non-rewetting (very resistant to water penetration) to fully rewetting (easily absorbs water). This scale is valuable in fields like geology, material science, and corrosion prevention to understand how materials interact with moisture, which can influence their durability and performance in various environments.
