Mortar composition 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 for repair and reinforcement of an underwater concrete structure and a repair and reinforcement method for an underwater concrete structure using the same. More specifically, in repairing and reinforcing the underwater concrete structure, physical strength such as compressive, bending, and tensile strengths of a repairing and reinforcing surface is strengthened. Durability and water resistance are improved by strengthening the bonding strength with a concrete surface, and chemical resistance and waterproof properties are excellent. Moreover, the present invention has excellent resistance to freeze-thawing and salt damage, can maintain a repair and reinforcement effect of the underwater concrete structure for a long time, and can stably complete underwater repair and reinforcement work in a short time, thereby being economical and solving environmental pollution and quality degradation problems caused by material separation. The present invention comprises 100 parts by weight of a binder, 100 to 200 parts by weight of a silica sand, 0.5 to 10 parts by weight of a reinforcing fiber, 10 to 50 parts by weight of a polymer, 0.5 to 2.0 parts by weight of a shrinkage prevention agent, 3 to 7 parts by weight of a silica fume, 0.5 to 10 parts by weight of a clinker, 0.5 to 10 parts by weight of a plaster, 0.5 to 10 parts by weight of an alpha-type hemihydrate gypsum, 0.01 to 5 parts by weight of a fly ash, 0.1 to 5 parts by weight of a red mud, 0.01 to 10 parts by weight of a calcined pozzolana, 0.01 to 10 parts by weight of a microsilica, 0.1 to 1.0 parts by weight of a defoamer, 5 to 10 parts by weight of an expanding agent, 0.1 to 10 parts by weight of a curing accelerator, 0.2 to 20 parts by weight of a fluidizing agent and 2 to 20 parts by weight of a thickener mixture.
본 발명은 수중 콘크리트 구조물 보수 보강용 모르타르 조성물 및 이를 이용한 수중 콘크리트 구조물의 보수 보강 공법에 관한 것으로서, 더욱 구체적으로는 수중 콘크리트 구조물을 보수 보강함에 있어 보수 보강 면의 압축 강도, 휨 강도, 인장강도 등 물리적 강도가 강화되며, 콘크리트 면과의 부착 강도가 강화되어 내구성과 내수성이 향상되고, 내화학성 및 방수성도 우수하며, 동경융해 및 염해에 대한 내성도 우수함으로써 수중 콘크리트 구조물의 보수 보강 효과를 장기간 유지할 수 있는 동시에 단시간에 수중 보수 보강 공사를 안정적으로 완료할 수 있어 경제성도 우수하고 재료 분리로 인한 환경 오염 및 품질 저하 문제를 해결할 수 있는 모르타르 조성물을 이용한 수중 콘크리트 구조물의 보수 보강 공법을 제공한다.
