Abstract: The absorption characteristics and sorptivity of cover concrete obtained by the initial surface absorption test (ISAT), the covercrete absorption test (CAT), and the sorptivity test have been studied and compared. Two types ...

Abstract: Four tests for measuring the surface properties of concrete have been studied: (1) The initial surface absorption test; (2) Figg's air permeation index (Figg) test; (3) the covercrete absorption test (CAT); and (4) the air ...

Abstract: Cementitious materials have traditionally not been economically viable for most landfill containment systems. Conventional liners have been made with clay and high-density polyethylene membranes, supporting packed aggregate ...
