Evaluating the Concrete’s First Line of Defense
The Initial Surface Absorption Test (ISAT) is a specific durability test that focuses on a concrete's near-surface characteristics. It measures the rate at which water is absorbed by the surface of a hardened concrete specimen when subjected to a constant, low pressure head of water. The test is required for several key reasons, primarily because the surface layer is the first line of defense against environmental and chemical attacks.
Why ISATMatters.
