Claim Text:
1. A system for measuring permeation properties of concrete and porous materials, consisting of: a chamber having an upper plate, a lower plate, a plurality of support members separating the upper plate and the lower plate, and at least one circumferential wall extending between the upper plate and the lower plate, wherein the at least one circumferential wall comprises an inner shell and an outer shell, the chamber being configured for holding a specimen; a plurality of supply tubes connected in fluid communication with the chamber, wherein the supply tubes consist of a single gas supply tube and a single liquid supply tube; a plurality of discharge tubes connected in fluid communication with the chamber, wherein the discharge tubes consist of a single gas discharge tube and a single liquid discharge tube; a gas flow measurement assembly connected in fluid communication with the gas discharge tube, the gas flow measurement assembly having a first pressure gauge and a gas flow meter; a liquid flow measurement assembly connected in fluid communication with the liquid discharge tube, the water flow measurement assembly having a second pressure gauge and a water flow meter; a gas cylinder connected in fluid communication with the gas supply tube, the gas cylinder being configured for supplying pressurized gas into the chamber; a plurality of valves disposed in the supply tubes and in the discharge tubes for regulating the flow of gas and liquid through the system; an air pressure gauge in fluid communication with the chamber; a first pressure relief valve in fluid communication with the chamber; and a second pressure relief valve in fluid communication with the gas supply tube.
