Description

아민유도체 및 이온교환수지를 이용한 하수시설 보수용 내황산 모르타르 분체 조성물{Composition of mortar powder for sewage treatment plant with amine derivatives and ionic reactions} Technical Field [0001] The present invention relates to a mortar powder composition for repairing a sewage system using an amine derivative and an ion exchange resin,

본 발명은 하수시설의 열화현상을 보수하는 데에 적용하는 모르타르 조성물에 관한 것으로, 특히 상기 모르타르 조성물에 아민유도체 및 이온교환수지를 혼입하여 열화요인의 제거 효율을 증대함으로써 철근 콘크리트 구조물의 수명을 연장하고 유지보수비용을 절감할 수 있도록 한 아민유도체 및 이온교환수지를 이용한 하수시설 보수용 내황산 모르타르 분체 조성물에 관한 것이다.The present invention relates to a mortar composition to be applied to repair deterioration phenomenon of a sewage facility. In particular, the lifetime of a reinforced concrete structure is extended by incorporating an amine derivative and an ion exchange resin into the mortar composition, The present invention relates to a mortar powder composition for repairing a sewage system using an amine derivative and an ion exchange resin.

일반적으로, 토목 및 건축분야에서 각종 철근 콘크리트 구조물은 외부적인 환경 요인의 복합적인 영향으로 인해 부식이나 중성화나 동해나 염해와 같은 각종 열화 현상이 진행되며, 이로 인해 상기 콘크리트 구조물 자체의 내하력 및 내구성의 저하는 물론 안전성이 떨어져서 수명이 저하된다.Generally, various reinforcing concrete structures in the civil engineering and construction fields are subjected to various deterioration phenomena such as corrosion, neutralization, corrosion or corrosion due to the combined effect of external environmental factors, and thereby the load bearing capacity and durability of the concrete structure itself Decreases as well as safety and lowers the service life.

특히, 현대사회는 인구가 증가하고 급속히 발달하여 도시의 거대화가 진행됨에 따라 상하수도와 같은 도시 형성에 필수적인 콘크리트 구조물 형태를 갖는 사회기반시설의 증대는 물론 유지관리가 요구되고 있다.Especially, as the population grows and rapidly develops and the urbanization becomes bigger, modern society is required to increase and maintain the infrastructure of the concrete structure, which is essential for the formation of cities such as water and sewage.

상기 콘크리트 구조물은 40년의 수명을 산정하고 있지만, 이는 건축구조물에서의 열화현상을 기반으로 산정된 결과이며, 하수도와 같은 밀폐되고 유해가스의 농도가 높은 하수시설의 경우 열화요인들에 더해 황산염 침식의 영향으로 인한 하수암거의 열화현상이 극심한 것으로 알려져 있다. Although the concrete structure estimates the life of 40 years, it is a result based on the deterioration phenomenon in the building structure. In case of the sewage facility having a high concentration of the closed and harmful gas such as the sewage, in addition to the deterioration factors, It is known that the deterioration phenomenon of the sewage culverts is extreme.

상기 하수시설의 특성상 하수암거의 교체는 대규모의 토목공사가 필수적으로 수반되며, 상기 하수암거의 교체과정에서 주변 시설의 사용 중지에 따른 경제적 손실이 발생함으로써, 상기 하수암거의 교체가 아닌 유지보수에 대한 관심이 높아지고 있으며, 상기 하수암거에 대한 적절한 유지관리를 실시하지 않을 경우 장기적으로 누적된 손상에 의해 하수 누수에 따른 환경오염이나 지반 불안정으로 인한 지반침하 등의 안전성에 심각한 문제를 야기할 수 있다.Due to the nature of the sewage system, the replacement of sewage culverts is accompanied by a large-scale civil engineering work. In the process of replacing the sewage culverts, there is an economic loss due to the suspension of use of the surrounding facilities. If the maintenance of the sewage culvert is not carried out properly, it may lead to serious problems in the safety such as subsidence due to environmental pollution due to sewage leakage or ground instability due to accumulated damage in the long term .

미국이나 유럽 등 선진 외국에서는 2차 세계대전 이후 건설된 시설물의 노후화로 인해 유지관리 비용이 전체 예산의 40~50%를 차지하는 등 유지관리비용이 증대하고 있으며, 유지관리에 관한 인식이 높은 이유로 인해 기술개발이 활발히 이루어지고 있다. 국내의 경우 1970~80년대에 사회기반시설이 집중적으로 건설되어 준공 후 30년 이상 된 노후화된 사회기반시설이 큰 비중을 차지하여 노후화가 심화되고 이에 따른 유지보수 예산이 점점 증가하고 있다. In advanced countries such as the United States and Europe, maintenance costs are increasing, for example, due to the deterioration of facilities built after the Second World War and maintenance costs account for 40 to 50% of the total budget. Technology development is actively being done. In Korea, the aged society infrastructure facilities, which have been constructed over 30 years since the construction of the infrastructure in the 1970s and 1980s, have been heavily weighted, and the aging has intensified and the maintenance budget has increased accordingly.

더욱이, 국내 건설시장은 유지보수보다는 신규사업에 집중되어 기술개발이 부족하며, 특히 하수도 시설의 경우 국민의 보건 및 위생확보 측면에서 파급효과가 매우 큰 사업임에도 지하매설물이라는 특수성으로 인해 도로나 교량과 같은 가시적인 사회기반시설보다는 우선순위에서 뒤처져 있다.In addition, the domestic construction market is focused on new business rather than maintenance, and technological development is lacking. Especially, in case of sewage facilities, it is a project that has a great effect on public health and hygiene. It lags behind the same visible infrastructure as priorities.

게다가, 상기 콘크리트 구조물의 열화방지와 관련된 대부분의 연구들을 살펴보면, 기존 기술의 하수관거, 하수암거 등의 보수 모르타르는 폴리머계 성분을 혼입하여 황산염의 콘크리트 침투를 방지하거나, 또는 고로슬래그나 플라이애시 등 포졸란 반응을 기반으로 한 소재를 혼입하여 황산염 침식을 방지하는 내용으로 모두 1차원적 차단 기술에 불과하여 연구가 절실하다.In addition, most studies related to the prevention of deterioration of the concrete structure are as follows. The existing mortar of repairing sewage, sewage, etc. is mixed with a polymer component to prevent the penetration of concrete in the sulfate, or the pozzolan It is a one-dimensional barrier technology that prevents the erosion of sulfate by incorporating reaction-based materials. Research is urgently required.

특히, 상기 콘크리트 하수시설 구조에서는 일반 열화 요인에 더하여 황산염 침식이 발생하기 때문에 기존의 단순 차단 기술로는 유해이온의 침투가 누적되거나, 침투저항성을 손실할 경우, 콘크리트의 내구성 저하가 발생하기 때문에 구조물의 열화를 예방 및 유지관리 하는데 어려움이 있다.Particularly, in the above-mentioned concrete sewage structure, sulfate attack occurs in addition to general deterioration factors. Therefore, when the penetration of harmful ions is cumulative or the penetration resistance is lost by the conventional simple blocking technique, the durability of the concrete is lowered. It is difficult to prevent and maintain deterioration of the apparatus.

따라서, 상기 콘크리트 하수암거와 같은 밀폐되고 유해가스의 농도가 높은 환경에서 발생하는 각종 열화요인(황산이온, 염화이온, 탄산이온)을 억제할 수 있는 모르타르 조성물의 확보가 절실한 실정이다.Therefore, it is inevitable to secure a mortar composition capable of suppressing various deterioration factors (sulfate ion, chloride ion, carbonate ion) generated in an environment where the concentration of harmful gas is high, such as the concrete sewage culvert.

이에, 본 발명은 상기한 문제점을 해결하기 위한 것으로서, 상기 모르타르 조성물에 아민유도체 및 이온교환수지를 혼입하여 열화요인의 제거 효율을 증대함으로써 철근 콘크리트 구조물의 수명을 연장하고 유지보수비용을 절감할 수 있도록 한 아민유도체 및 이온교환수지를 이용한 하수시설 보수용 내황산 모르타르 분체 조성물을 제공하는 데에 그 목적이 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a mortar composition which can improve the lifetime of a reinforced concrete structure and reduce maintenance costs by enhancing removal efficiency of deterioration factors by incorporating an amine derivative and an ion- And to provide a powdery manganese sulfate mortar composition for repairing a sewage system using an amine derivative and an ion exchange resin.

이상과 같이, 본 발명은 적어도 다음의 효과를 제공한다.INDUSTRIAL APPLICABILITY As described above, the present invention provides at least the following effects.

첫째, 상기 모르타르 조성물에 혼입된 아민유도체 및 이온교환수지를 이용하여 황산이온과 같은 열화요인의 침투를 차단함으로써, 상기 구조물내의 철근을 보호함은 물론 기반시설 확보 및 유지관리가 용이하다.First, the permeation of deterioration factors such as sulfate ions is prevented by using the amine derivative and the ion exchange resin incorporated in the mortar composition, thereby protecting the reinforcing bars in the structure and facilitating the maintenance and maintenance of the infrastructure.

즉, 상기 모르타르 조성물에 의해 상기 구조물에 서식 및 증식하는 미생물의 생성을 원천적으로 차단함으로써, 상기 열화요인에 의한 구조물 부식이나 열화가 방지되어 상기 콘크리트 구조물의 수명이 연장된다.That is, the mortar composition essentially blocks generation of microorganisms in the form and proliferation of the structure, thereby preventing corrosion or deterioration of the structure due to the deterioration factor, thereby prolonging the life of the concrete structure.

둘째, 상기 모르타르 조성물에 의해 상기 구조물의 빠른 유지 및 보수가 가능해짐으로써, 상기 구조물의 사용기간이 연장됨은 물론 상기 구조물의 유지보수에 소요되는 비용을 절감할 수 있어 매우 경제적이다.Second, since the structure can be quickly maintained and repaired by the mortar composition, the service life of the structure can be prolonged, and the cost for maintenance and repair of the structure can be reduced, which is very economical.

셋째, 상기 모르타르 조성물에 강도보강제 및 유동화제를 혼입함으로서 상기 구조물의 휨강도나 압축강도와 같은 물리적 특성 및 구조물 보수에 있어 시공 성능을 향상시키며, 상기 증점제 및 응결촉진제에 의해 구조물과의 부착성능이 향상되어 수명이 연장된다.Third, by incorporating the strength reinforcing agent and the fluidizing agent into the mortar composition, the physical properties such as the bending strength and the compressive strength of the structure and the construction performance in the repair of the structure are improved, and the adhesion performance with the structure is improved by the thickener and the condensation promoter So that the life span is prolonged.

넷째, 상기 모르타르 조성물에 재유화형 분말수지를 혼입함으로서 상기 구조물의 초기 강도 향상의 증대는 물론 상기 구조물의 내부구조를 더욱 더 치밀하게 유지하여 상기 구조물의 내구성이 더욱 향상된다.
