Abstract
A testing pressure vessel for permeability testing of a cured concrete sample. The testing pressure vessel includes a cylindrical pressure vessel with a sample injection port and a casing fluid injection port, and a casing fluid outlet port and an outlet port. The testing pressure vessel also includes a hydraulic inlet, and a sleeve positioned adjacent to an inner surface of the cylindrical pressure vessel and the hydraulic inlet. The testing pressure vessel further includes a plurality of pressure ports to measure a pressure exerted on the sleeve. The testing involves applying confining pressure and injection pressure to the cured concrete sample, to have the confining pressure to at least 300 psi higher than the injection pressure until a predetermined injection pressure is achieved. The testing further includes measuring the permeability of the cured concrete sample directly by measuring the pressure exerted on the sleeve.
