| Abstract: | Subway structure is located in underground aggressive condition.The durability of structural concrete has attracted considerable interest,but generally accepted testing method to detect the performance of existing concrete is lacking.In this paper gas permeability test was used to analyze the concrete permeability character of the subway structure. Scanning Electron Microscope(SEM) and energy spectrum analysis were used to examine the in-service changing of hydration crystal and the materials characteristic... |
