Title: Laboratory Permeability Measurement
Author(s): D. J. Janssen
Publication: Special Publication
Appears on pages(s): 145-158
Keywords: concretes; measuring instruments; permeability; samples; tests; test equipment; General
Abstract:Equipment and procedures for measuring actual permeability of portland cement concrete are presented. The equipment is built from readily available parts and materials and requires only standard laboratory air pressure and vacuum sources. The sample size used is 3 in. (7.5 cm) diameter x 3-1/8 in. (8 cm) long, but other sample sizes could be used. Typical measurements are presented to show repeatability and time required for permeability testing. The equipment has been used for permeabilities as low as 1 x 10-11 cm/sec. Concrete with lower permeability would require equipment modifications and/or longer measurement times.
