The apparatus is used for testing gas permeability of a concrete test sample, and includes a gas supply apparatus, an instrument body and a gas flow meter. The instrument body includes a frame body. A gas inlet ring, a gas outlet ring and a connection plate are successively arranged on the frame body from inside to outside. An input end of the gas inlet ring is connected with the gas supply apparatus, and an output end is connected with an input end of the gas outlet ring through the concrete test sample. An output end of the gas outlet ring is connected with the gas flow meter. The connection plate is connected with the concrete test sample."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Testing apparatus for gas permeability in concrete and testing method therefor","description":"An apparatus and method for testing gas permeability in concrete are provided.
