Characterizing Physical Properties of Clay by Water Vapor Sorption
This paper summarizes the authors' recent research related to geotechnical characterization of clays and clayey soils using measurements of water vapor sorption behavior. Testing equipment for determining water vapor sorption isotherms is described and evaluated. Applications of sorption measurements toward understanding interlayer swelling behavior, classifying expansive clays, and estimating fundamental surface properties such as specific surface area (SSA) are illustrated. Sorption-based soil characterization is advocated as an alternative to conventional clay characterization approaches such as Atterberg's limits. Sorptionbased clay characterization is more firmly rooted in fundamental clay compositional properties and relies on measurement techniques that are potentially more systematic, economical, and readily automated.
