MORTAR COMPOSITION WITH EXCELLENT WET CURABLE PROPERTIES AND METHOD OF REPAIRING CONCRETE STRUCTURE USING THE SAME
The present invention relates to a mortar composition with excellent wet surface workability, and a section repair method using the same. More specifically, the mortar composition contains: a wet fast-hardening binder containing 20 to 30 parts by weight of alumina cement, 10 to 15 parts by weight of blast furnace slag powder, 10 to 15 parts by weight of calcium sulfoaluminate, 5 to 10 parts by weight of activated silica with a silicon dioxide content of 70 wt% or more, 5 to 10 parts by weight of natural anhydrous gypsum powder, 2 to 5 parts by weight of waste insulator powder, 2 to 3 parts by weight of silica sol, and 2 to 3 parts by weight of an inorganic stimulant; a polymer binder containing 3 to 5 parts by weight of a powder resin and 3 to 5 parts by weight of an MMA resin; filled aggregate containing 30 to 50 parts by weight of silica sand and 3 to 5 parts by weight of zeolite; and a porous binder containing 1 to 2 parts by weight of perlite powder and 1 to 2 parts by weight of kaolinite powder. With the present invention, curing can be performed even on a wet section, and thus adhesiveness can be improved in relation to a concrete section. In addition, the polymer content is low, the fine powder-based inorganic binder continuously fills the fine structure of the concrete section, and thus hardness is exhibited with time. Also, insulation, sound absorption, deodorization, moisture absorption, and chemical resistance are exhibited by the porous binder.
본 발명은 습윤면 시공성이 우수한 모르타르 조성물 및 이를 이용한 단면보수공법에 관한 것으로, 보다 상세하게는, 알루미나 시멘트 20~30중량부, 고로슬래그분말 10~15중량부, 칼슘설포알루미네이트 10~15중량부, SiO2 함량이 70중량%이상인 활성실리카 5~10중량부, 천연무수석고분말 5~10중량부, 폐애자 분말 2~5중량부, 실리카졸 2~3중량부 및 무기자극제 2~3중량부를 포함하는 습윤속경성 결합재와; 분말수지 3~5중량부, MMA수지 3~5중량부를 포함하는 폴리머 결합재와; 규사 30~50중량부, 제올라이트 3~5중량부를 포함하는 충전골재와; 펄라이트 분말 1~2중량부 및 카올리나이트 분말 1~2중량부를 포함하는 다공성결합재;를 포함하여 조성되어 습기가 있는 단면에서도 경화가 가능하여 콘크리트 단면과의 부착력을 향상시키고, 폴리머 함량이 낮아 미분 무기결합재가 지속적으로 콘크리트 단면 미세구조를 충진하여 시간이 경과됨에 따라 강도를 발현하며, 다공성결합재에 의하여 단열, 흡음, 탈취, 흡습 및 내화학성능을 발휘하는 습윤면 시공성이 우수한 모르타르 조성물 및 이를 이용한 단면보수공법에 관한 것이다.
