Mortar composition of underwater inseparable type for repairing and reinforcing underwater concrete structures and method of repairing and reinforcing underwater concrete structures using the same
The present invention relates to a mortar composition of an underwater inseparable type for repairing and reinforcing an underwater concrete structure, and a method of repairing and reinforcing an underwater concrete structure using the same. More specifically, the present invention provides a method of repairing and reinforcing an underwater concrete structure using a mortar composition of an underwater inseparable type, which can maintain repairing and reinforcing effects for a long time as long-term durability and adhesion strength with a concrete structure are improved in repairing and reinforcing an underwater concrete structure and simultaneously, obtain excellent economic feasibility and solve problems of quality degradation and environmental pollution due to material separation since underwater repairing and reinforcing works can be stably completed in a short time. The mortar composition of an underwater inseparable type contains 100 parts by weight of a binder, 100-200 parts by weight of silica sand, 0.5-10 parts by weight of reinforcing fiber, 10-50 parts by weight of a polymer, 0.5-2.0 parts by weight of a shrinkage inhibitor, 3-7 parts by weight of fume silica, 0.1-1.0 parts by weight of an antifoaming agent, 5-10 parts by weight of an expanding agent, 0.1-10 parts by weight of a curing accelerator, 0.2-20 parts by weight of a fluidizing agent and 1-20 parts by weight of a material separation reducing agent.
본 발명은 수중 콘크리트 구조물 보수 보강용 수중 불분리성 모르타르 조성물 및 이를 이용한 수중 콘크리트 구조물의 보수 보강 공법에 관한 것으로서, 더욱 구체적으로는 수중 콘크리트 구조물을 보수 보강함에 있어 장기 내구성과 콘크리트 구조물과의 부착 강도가 향상되어 보수 보강 효과를 장기간 유지하는 동시에 단시간에 수중 보수 보강 공사를 안정적으로 완료할 수 있어 경제성도 우수하고 재료 분리로 인한 환경 오염 및 품질 저하 문제를 해결할 수 있는 수중 불분리성 모르타르 조성물을 이용한 수중 콘크리트 구조물의 보수 보강 공법을 제공한다.
