본 발명은 산업부산물을 활용한 친환경 내황산염 모르타르 조성물 및 이를 이용한 콘크리트 단면복구시공공법에 관한 것으로, 보다 상세하게는 경량골재인 질석과 무기질 재료인 액상규산나트륨(Na2O·nSiO2·xH2O)를 혼합, 가압하여 제조된 질석보드를 절단 및 가공하는 공정에서 발생되는 질석보드스크랩을 분쇄한 질석 및 규산소다 함유 폐분말과, 니켈 제련과정에서 발생하는 니켈슬래그를 분쇄한 니켈슬래그분말과, 유리섬유시트 제조공정중 절단공정에서 발생하는 유리섬유시트를 분쇄한 폐유리분말을 포함하여 조성되는 산업부산물을 활용한 친환경 내황산염 모르타르 조성물 및 이를 이용한 콘크리트 단면복구시공공법에 관한 것이다.The present invention relates to a concrete section Recovery construction method by Eco sulfate mortar composition and using the same advantage of the industrial by-products, more particularly to a lightweight aggregate in the liquid sodium silicate is vermiculite and the inorganic material (Na 2 O · nSiO 2 · xH 2 O), a powder of vermiculite and sodium silicate containing pulverized vermiculite board scrap generated in the process of cutting and processing the vermiculite board produced by pressurization, nickel slag powder obtained by crushing nickel slag generated in the nickel smelting process, And a waste glass powder obtained by pulverizing a glass fiber sheet produced in a cutting process during a glass fiber sheet manufacturing process, and to a method of recovering and rehabilitating a concrete section using the waste by-product.
철근 콘크리트 구조물은 화학적 부식환경, 염해 및 중성화, 수분침투 등에 의해 내부의 철근이 부식하게 되고, 철근의 부식은 철근의 팽창으로 이어져 결국 콘크리트구조물이 열화되면서 장기적으로 내구성 및 사용성 저하를 초래한다.Reinforced concrete structures are subject to chemical corrosion, corrosion and neutralization, water penetration, and corrosion of reinforcing bars leads to expansion of reinforcing bars, resulting in deterioration of concrete structures, resulting in long-term durability and poor usability.
이러한 구조물의 열화는 계속 진행되면 결국 구조물의 붕괴를 초래할 위험성이 있기 때문에 콘크리트 구조물의 내구성 증진을 위해 지속적으로 단면복구나 표면보호와 같은 보수공법들이 사용되고 있다.As the deterioration of these structures continues, there is a danger of causing the collapse of the structure.

Therefore, in order to secure the stability and performance of the reinforced concrete structure, It is necessary to suppress the progress of deterioration and restore and improve durability performance.
따라서, 콘크리트의 열화, 강재의 부식, 기타의 원인에 의해 구조물 단면의 박리나 탈락 등의 열화인자를 포함하는 콘크리트 부분을 제거한 후 단면을 그 원래의 성능 및 형태로 복원하기 위해 단면복구재료를 충진하거나 뿜칠 시공을 하여 보수를 실시한다.Therefore, in order to restore the section to its original performance and form after removing the concrete part including the deterioration factor such as detachment or detachment of the section of the structure due to deterioration of concrete, corrosion of steel, Or repairs by spraying.
