Title:
TESTING APPARATUS FOR GAS PERMEABILITY IN CONCRETE AND TESTING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/176898
Kind Code:
A1
Abstract:
Disclosed are a testing apparatus for gas permeability in concrete and a testing method therefor. The testing apparatus is used to test the gas permeability in a concrete test sample and comprises a gas supply device (2) and a gas flowmeter (4), and the apparatus further comprises an instrument body (3). The instrument body (3) comprises a frame (36); a gas inlet ring (31), a gas outlet ring (32) and a connecting plate (33) are successively arranged on the frame (36) from inside to outside; an input end of the gas inlet ring (31) is connected to the gas supply device (2), and an output end thereof is connected to an input end of the gas outlet ring (32) via a concrete test sample (1); an output end of the gas outlet ring (32) is connected to the gas flowmeter (4); the connecting plate (33) is connected to the concrete test sample (1); the gas supply device (2) provides a test gas for the instrument body (3); and the test gas flows from the gas inlet ring (31) to the gas flowmeter (4) successively through the concrete test sample (1) and the gas outlet ring (32), so that the gas permeability coefficient in the concrete is calculated according to the gas flow. Compared with the prior art, the apparatus and the testing method have the advantage of convenient use.
