摘要: In order to study the chloride ion transport performance in fly ash addition mortar, a new method, which fatigue loading and diffusion are undertaken simultaneously, was developed. This method realizes coupling damage process of transporting mortar. The mortar specimens studied under different stress levels. Moreover, effect content on investigated. AE (Acoustic Emission) SEM were used acquire distribution action load. results show that coefficient increases with level loading. can mitigate penetration ion. microcrack 3D location acquired by AE, accompanied crack characterizing from SEM, indicate degree specimen Furthermore, higher leads more sample.
