Beschreibung
Zusammenfassung:	The present invention relates to a room-temperature fast-curing composition for concrete crack repair and a gravity-type cracked concrete repairing method using the same, and provides a room-temperature fast-curing composition injected to a crack by capillary force, containing 90-99.8 wt% of binder, 0.1-5 wt% of coupling initiator, and 0.01-5 wt% of a curing accelerator, based on solids weight, wherein the binder contains 40-97 wt% of methyl methacrylate, 1-20 wt% of butyl acrylate, 1-20 wt% of polymethyl methacrylate, and 1-20 wt% of 1,6-hexanediol diacrylate, based on a total weight of the binder. The composition has non-irritation, sufficient pot life, and excellent ductility, strength, durability, and permeability. 본 발명은 상온 속경형 콘크리트 균열 보수 조성물 및 이를 이용한 중력식 균열 콘크리트 보수 방법에 관한 것으로서, 고형분 중량을 기준으로, 결합재 90~99.8중량%; 결합개시제 0.1~5중량%; 및 경화촉진제 0.01~5중량%를 포함하고, 상기 결합재는 결합재 전체 중량을 기준으로 메틸메타크릴레이트 40~97중량%, 부틸아크릴레이트 1~20중량%, 폴리메틸메타크릴레이트 1~20중량% 및 1,6-헥산디올 디아크릴레이트 1~20중량%를 포함하는, 상온 속경화형 모세관력 주입 균열 조성물을 제공한다.
