Performance Evalution of Chloride Ion Penetration of Polymer Mortar for Section Restoration

단면복구용 폴리머 모르타르의 염소이온 투과성 평가

Recently, polymer mortar has been developed not only more improving the performance of modified mortar with polymer, but also protecting and repairing materials of structures, especially in marine environment because of their excellent performance to improve compressive strength, flexural strength, and adhesive strength. however, in fact, these rehabilitation techniques in marine environment, which consist of removing delaminated areas of concrete, cleaning affected steel and patching with polymer mortar, have proven to be ineffective for marine structures. Also, repairs are often repeated every several years. Therefore, it is neccessary to research performance evalution of chloride ion penetration of polymar mortar for section restoration.
