ActiveThe method for determining the chloride diffusion coefficient for cement mortar
水泥胶砂氯离子扩散系数检测方法
Application Summary AI generated
This standard specifies a test method for determining the chloride diffusion coefficient in cement mortar, which is critical for evaluating the durability of concrete structures against chloride-induced corrosion. It is applied in the construction industry, particularly for quality control and mix design of cement-based materials used in marine environments, bridges, and other infrastructure exposed to de-icing salts or seawater. The method provides a standardized procedure for laboratory testing to predict the long-term service life of reinforced concrete.
