Description
본 발명은 바잘트 섬유를 이용한 보강제 조성물에 관한 것으로서, 더욱 상세하게는 콘크리트 구조물 등의 균열부위, 손상부 등에 적용되어 보강을 하기 위한 바잘트 섬유를 이용한 보강제 조성물에 관한 것이다.
More particularly, the present invention relates to a reinforcing agent composition using a bar-sheathed fiber to be applied to a cracked portion or a damaged portion of a concrete structure or the like and to reinforce the same.
일반적으로 구조물은 시간이 지남에 따라 설계 및 시공 상의 하자, 사용 중의 구조변경, 환경변화에 따른 노후화 및 자연재해, 화재 등 각종 원인에 의해 내구성 및 내하력이 저하되며, 이러한 원인에 의해 구조적으로 영향을 받게 된 구조물들은 균열 등으로 인하여 붕괴로까지 이어질 수 있어 인명피해 등 대형 참사뿐만 아니라, 사회 기반인 주요시설 및 교통망이 장기간 마비되고 복구를 위해서는 막대한 공사비가 소요되어 사회적으로 큰 영향을 미친다.Generally, as time goes by, the durability and the load-bearing capacity are reduced due to various causes such as design and construction defects, structural changes during use, aging due to environmental changes, natural disasters and fire, Structures received can lead to collapse due to cracks, etc., and not only large-scale disasters such as human casualties, but also large-scale construction costs are required for major facilities and transportation networks to be repaired and restored.
한편, 구조적인 손상을 입은 구조물들은 안전성 확보를 위해 전면 또는 부분적인 보수/보강조치가 반드시 필요하며, 특히, 구조적인 손상을 유발하는 균열은 외부의 영향 다시 말해, 콘크리트 구조물과 이웃하는 토사에 빗물 등이 응축되어 있다가 구조물 표면으로 스며들면서 열화가 발생하게 되어 발생하는 것이 대부분이다.On the other hand, structures damaged by structural damage are required to have full or partial repair / reinforcement measures in order to secure safety. In particular, cracks that cause structural damage are affected by external influences, that is, Etc. are condensed and then deteriorate as they penetrate into the surface of the structure.
특히, 콘크리트 구조물은 콘크리트의 건조와 수축, 온도변화, 누수, 진동 등 여러 요인에 의해 외부 또는 내부에 균열이 발생될 가능성이 매우 높으며, 차량이나 열차의 통행이 많은 터널, 지하철의 차량 통로에는 진동 등의 여러 요인에 의해 균열이 빈번하게 발생된다.Especially, the concrete structure is very likely to crack on the outside or inside due to various factors such as drying and shrinkage of concrete, temperature change, leakage, vibration, etc. In addition, Cracks often occur due to various factors such as the size of the cracks.
이러한 콘크리트의 균열 부분은 외부의 수분 및 공기의 유입이 쉽게 이루어지므로 콘크리트의 풍화를 촉진하고, 철근의 부식을 초래하여 콘크리트 구조물의 수명 및 안전성에 치명적인 악영향을 미치게 된다.The cracks of the concrete can easily infiltrate with external moisture and air, thereby accelerating the weathering of the concrete and causing corrosion of the reinforcing bars, which has a deleterious effect on the life and safety of the concrete structure.
한편, 이러한 구조물, 특정적으로 콘크리트 구조물을 보강하기 위한 방법으로 콘크리트 구조물의 균열 부위에 팩커(Packer) 및 보수보강제 등을 이용하여 보수/보강하는 것이 일반적이다.On the other hand, as a method for reinforcing a concrete structure by such a structure, specifically, it is general to repair / reinforce the cracked portion of the concrete structure by using a packer and a repair or reinforcing agent.
이러한 균열을 보수하는 일례로서, 대한민국 특허 제1119232호에는 콘크리트 구조물의 균열부위에 레진을 주입하여 보강하는 콘크리트 균열 보강용 주입식 에폭시 조성물을 이용한 콘크리트 구조물 보강 공법이 개시되어 있다.
As an example of repairing such cracks, Korean Patent No. 1119232 discloses a concrete structure reinforcing method using an injection-type epoxy composition for reinforcing concrete cracks which is reinforced by injecting resin into a cracked portion of a concrete structure.
본 발명은 상기와 같은 문제점을 해결하기 위해 창출한 것으로서, 기계적 강도가 우수한 바잘트 섬유를 이용하여 보강제 조성물을 구성함으로써, 손상부 주변과의 접착성을 향상시키는 동시에, 기계적 물성, 우수한 방수성 및 장기 내구성을 증가시키도록 하는 보강제 조성물을 제공하고자 한다.
The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a reinforcing agent composition by using a barametal fiber having excellent mechanical strength to improve adhesiveness to the periphery of a damaged portion, And to provide a reinforcing agent composition which increases durability.
