Specification:
The test is performed clamping the specimen – cubic, cylindrical or
prismatic of length of edge, or diameter not less than 150 mm – between
two flanges with special circular gaskets.
This apparatus is used to determine the depth of penetration of water under pressure in the concrete specimens.
The permeability is determined on cement mortar and
concrete specimens, either cast in the laboratory or obtained by cutting
out cores from existing structures.
The design of concrete mix aims at maximum durability for the conditions
prevailing at the site where it is to be used ability to resist the
flow of water through, is one of the important durability
characteristics.
