Permeability of hardened concrete?

[morecoffeeplz]

Anyone know if there is a standard test to measure the hydraulic conductivity of hardened concrete?

From the ACI website:

Q. How is the permeability of concrete determined?

A. With difficulty and usually indirectly, indications of the permeability of concrete are determined by air and water permeability tests (ACI 228.2R); or by the ponding test (ASTM C1543); or by the rapid chloride penetration test (ASTM C1202).

We use electrical conductivity for permeability of concrete. I don't work in that lab, but I'm sure they follow some test method.

Here's the test method that we use:
