The present invention relates to a mortar composition which is used for maintenance of a degradation phenomenon caused by durability degradation of sewage culvert and sewage treatment facilities. The mortar composition comprises 22 to 30 parts by weight of a cement binding agent, 15.5 to 20.5 parts by weight of a strength reinforcing agent, 0.33 to 0.5 parts by weight of a performance improving agent, 2.8 to 4.5 parts by weight of an ion reducing agent, and 48 to 52 parts by weight of a silica, based on 100 parts by weight of the mortar composition. Therefore, it is possible to prevent penetration and generation of a degradation cause such as sulfuric acid ion by using amine derivatives and ion exchange resin mixed in the mortar composition, thereby not only protecting reinforcing steel in a structure but also facilitating securement and maintenance of infrastructure. 본 발명은 하수암거 및 하수처리시설의 내구성 저하로 발생되는 열화현상을 보수하는 데에 이용하는 모르타르 조성물에 관한 것으로, 상기 모르타르 조성물 100 중량부에 대하여, 시멘트결합제 22~30 중량부, 강도보강제 15.5~20.5 중량부, 성능개선제 0.33~0.5 중량부, 이온저감제 2.8~4.5 중량부, 규사 48~52 중량부를 포함함으로써, 상기 모르타르 조성물에 혼입된 아민유도체 및 이온교환수지를 이용하여 황산이온과 같은 열화요인의 침투 및 생성을 차단함으로써, 상기 구조물 내의 철근을 보호함은 물론 기반시설 확보 및 유지관리가 용이하다.
