Highlights Absorption and desorption properties of 15 commercially available expanded shale, clay and slate fine LWA were measured. Analyzed LWA present a wide range of 24 h water absorption (6–31%). 85–98% of the 24 h absorbed water is released at RH greater than 93%. Normalized results show benefits of a single function that describes a large class of LWA for use in internal curing.
