Abstract：The erosion and damage mechanism of chloride salt snow melting agents on concrete and the method to improve the performance of concrete against chloride ion erosion were reviewed, which could be divided into chemical erosion and physical damage, the former mainly includes base ion erosion and chloride ion erosion, and the latter mainly includes crystallization damage and exfoliation damage. Chloride salt snow melting agents on the concrete and the ecological environment have a certain degree of harm, but due to its extremely cost-effective, the future remains the mainstream choice. At present, the main means of delaying concrete erosion by chloride ions are to improve the densification, modified ultra-hydrophobic and optimization of cementitious materials, a variety of means used can achieve the optimal protection effect. It is considered that the key to solve the chloride ion attack is to control the low water-cement ratio of concrete to inhibit the transport of water in concrete in order to enhance the service life of concrete.
