Abstract:
A simple test to estimate the permeability of concrete is described. Movement of water under gravity through a 12.5 x 10 mm (1/2 x 4 in.) disc of concrete is monitored at atmospheric pressure. Steady state conditions are reached typically in 7 to 14 days, and values of permeability can be determined reliably in 14 through 20 days. The reproducibility of the test is satisfactory, and preliminary measurements indicate that it can discriminate between concretes that have been subjected to different curing conditions or excessive loads.
