Applications:
ISAT method provides data for assessing the uniaxial water penetration characteristics of concrete surface. The result can be considered to be related to the quality of finish and to the durability of the surface under the effects of natural weathering. The results are of little relevance to behavior under higher water pressures, and cannot be used to assess the permeability of a body of concrete.
