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 ...
