Description
본 발명은 에폭시 수지를 이용한 균열 보수보강제 조성물에 관한 것으로서, 더 상세하게는 콘크리트 구조물 등의 균열부위에 적용되어 보수 및/또는 보강을 하기 위한 에폭시 수지를 이용한 균열 보수/보강제 조성물에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a crack repair and reinforcement composition using an epoxy resin, and more particularly, to a crack repair / reinforcement composition using epoxy resin for repairing and / or reinforcing a crack applied to a concrete structure or the like.
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, 보수보강제 조성물에 에폭시 수지, 충진제, 경화제, 섬유 등을 포함시켜, 균열부 주변과의 접착성을 향상시키는 동시에, 우수한 방수성 및 장기 내구성을 증가시키도록 하는 균열 보수보강제 조성물을 제공하고자 한다.

본 발명에 따른 균열 보수보강제 조성물, 특정적으로 에폭시 수지를 이용한 균열 보수보강제 조성물은 균열부 특정적으로 콘크리트, 예를 들면 콘크리트 구조물의 균열부에 적용함으로써, 우수한 방수성 및 장기 내구성 등을 증가시키도록 하는 것이라면 특별히 한정되지 않는다.The composition of the present invention for crack repair and reinforcement, specifically the composition for repairing cracks using an epoxy resin, is applied to the cracks of concrete, for example, concrete structures, specifically to increase the water resistance and durability It is not particularly limited.
본 발명에 따른 에폭시 수지는 당업계에서 통상적으로 사용되는 에폭시 수지라면 특별히 한정되지 않는다.The epoxy resin according to the present invention is not particularly limited as long as it is an epoxy resin commonly used in the art.
본 발명에 따른 균열 보수보강제 조성물의 에폭시 수지 외 나머지 성분들의 함량은 에폭시 수지 100중량부를 기준으로 한다.The content of the remaining components other than the epoxy resin in the crack repair or reinforcement composition according to the present invention is based on 100 parts by weight of the epoxy resin.
본 발명에 따른 칼슘설포알루미네이트(Calcium Sulfo Aluminate)는 수축보상, 고강도, 예를 들면 높은 압축강도와 휨강도 및 초속경을 부여하기 위한 물질로서, 이러한 목적을 갖는 칼슘설포알루미네이트라면 어떠한 것을 사용하여도 무방하며, 그 사용량은 에폭시 수지 100중량부 기준으로 5 내지 30중량부인 것을 추천한다.The calcium sulfoaluminate according to the present invention is a material for imparting shrinkage compensation, high strength, for example, high compressive strength, bending strength and ultrahigh speed, and any of calcium sulfoaluminate having such a purpose can be used And it is recommended that the amount thereof is 5 to 30 parts by weight based on 100 parts by weight of the epoxy resin.
여기서, 상기 칼슘설포알루미네이트의 사용량이 5중량부 미만이면 경화속도가 감소하고 30중량부 이상인 경우 체적이 팽창되는 문제점이 발생할 수 있다.If the calcium sulfoaluminate is used in an amount of less than 5 parts by weight, the curing rate may decrease. If the calcium sulfoaluminate is used in an amount of more than 30 parts by weight, the volume may expand.
한편, 상기 칼슘설포알루미네이트는 물과 접촉할 경우 순식간에 반응하여 에트린가이트(Ettringite) 수화물을 생성함으로써, 보수보강제 조성물의 압축강도를 수분 내지 수 시간 안에 얻을 수 있도록 한다.On the other hand, when the calcium sulfoaluminate comes into contact with water, the calcium sulfoaluminate reacts instantaneously to generate an ettringite hydrate, so that the compressive strength of the maintenance enhancer composition can be obtained within several minutes to several hours.
이때, 보다 신속한 수화반응을 위해 초미립 비정질 칼슘설포알루미네이트를 사용할 수도 있다.At this time, ultrafine amorphous calcium sulfoaluminate may be used for a quick hydration reaction.
상기 수화반응성 증대를 위해 사용되는 초미립 비정질 칼슘설포알루미네이트의 블레인 분말도는 5,000 내지 8,000㎠/g 정도인 것이 좋다.The blast powder of the ultrafine amorphous calcium sulfoaluminate used for increasing hydration reactivity is preferably about 5,000 to 8,000 cm 2 / g.
특정 양태로서, 본 발명에 따른 칼슘설포알루미네이트는 28 내지 62중량%인 압연종말슬러지와, 19 내지 52중량%인 백운석슬러지와, 9 내지 20중량%인 부산석고가 포함되도록 구성되고, 상기 혼합물의 입도가 88㎛, 잔분이 5 내지 20중량%로 분쇄되어 이루어질 수 있다.In a particular embodiment, the calcium sulfoaluminate according to the present invention is comprised of 28 to 62 wt.% Rolled end sludge, 19 to 52 wt.% Dolomite sludge, and 9 to 20 wt.% Gypsum plaster, By weight and the balance of 5 to 20% by weight.
이후에, 상기 혼합물을 소성로에서 1,000 내지 1,300℃의 소성온도로 1시간 이상 유지한 후 공냉시켜, 칼슘설포알루미네이트를 제조하게 된다. 이때, 소성온도가 낮거나, 백운석슬러지의 함량이 높은 경우에는 미반응 석회의 양이 많아져 팽창성을 나타내므로 붕괴, 파괴의 염려가 있으며, 소성온도가 높거나 석회석 배합량이 적어도 칼슘설포알루미네이트의 생산이 적어져 소기의 목적을 달성할 수 없다.Thereafter, the mixture is maintained at a firing temperature of 1,000 to 1,300 DEG C for at least one hour in a firing furnace, followed by air cooling to produce calcium sulfoaluminate. At this time, when the calcination temperature is low or the content of dolomite sludge is high, the amount of unreacted lime is increased to cause expansion, so there is a risk of collapse and destruction. When the calcination temperature is high or the amount of limestone is at least calcium sulphoaluminate The production is small and the desired purpose can not be achieved.
본 발명에 따른 충진제는 치수 안정성 및 내마모성을 향상시키기 위한 것으로서, 이러한 목적을 갖는 충진제라면 어떠한 것을 사용하여도 무방하며, 그 사용량은 에폭시 수지 100중량부를 기준으로 5 내지 50중량부인 것이 좋다.The filler according to the present invention is intended to improve dimensional stability and abrasion resistance. Any filler having such a purpose may be used, and the filler is preferably used in an amount of 5 to 50 parts by weight based on 100 parts by weight of the epoxy resin.
바람직한 충진제로는 수산화알루미늄, 탄산칼슘 또는 이들의 혼합물을 추천한다.Preferred fillers are aluminum hydroxide, calcium carbonate or mixtures thereof.
본 발명에 따른 섬유는 보수보강제 조성물의 강도 등을 향상시키기 위한 것으로서, 이러한 목적을 갖는 당업계의 통상적인 섬유라면 특별히 한정되지 않는다.The fiber according to the present invention is intended to improve the strength and the like of the repair or reinforcing agent composition and is not particularly limited as long as it is a conventional fiber in the art having such a purpose.
바람직한 섬유로는 현무암 섬유, 아라미드 섬유, 유리섬유, 탄소섬유 또는 이들로부터 선택된 적어도 하나 이상의 혼합물을 사용할 수 있고, 그 사용량은 에폭시 수지 100중량부 기준으로 10 내지 40중량부를 사용하는 것이 좋다.Preferred examples of the fiber include basalt fiber, aramid fiber, glass fiber, carbon fiber, and at least one mixture thereof. The amount of the fiber used is preferably 10 to 40 parts by weight based on 100 parts by weight of the epoxy resin.
여기서, 상기 현무암섬유는 유리섬유와 화학적 성질이 서로 유사하다. 즉, 유리와 현무암 모두 실리카를 주성분으로 하는 비결정성 소재이다.Here, the basalt fiber has chemical properties similar to those of glass fiber. In other words, both glass and basalt are amorphous materials based on silica.
또한, 상기 카본섬유는 고강도로서 현무암 섬유에 비하여 큰 우위에 있다. 그러나 탄성률이 1.5%로 현무암 섬유 4.2%에 비해 매우 낮아 섬유가공 측면에서 어려운 부분도 있다.In addition, the carbon fibers are high in strength and superior in strength to basalt fibers. However, the modulus of elasticity is 1.5%, which is much lower than that of basalt fiber (4.2%).
상기 아라마이드 섬유는 실의 형태로 뽑아 직물을 만드는 데 사용하는 필라멘트 형태, 분말형태로 형성하여 제품을 만드는 데 사용하는 펄프형태, 실의 두께를 자유롭게 조정함은 물론 다른 성질의 실과 혼방하여 사용하기 위해 약한 분쇄가공을 한 스테플 형태가 있는데, 본 발명에서는 필요에 따라 이중 선택된 어느 하나의 형태로 적용될 수 있다.The aramid fiber is formed into a filament form used to make a fabric by being pulled out in the form of a thread, a pulp form used to make a product in a powder form, a flexible thickness of the yarn, and a blend with other yarns There is a staple shape subjected to a weak grinding process. In the present invention, it can be applied to any one of the dual selected shapes as needed.
한편, 상기 아라미드 섬유는 단일 형상을 갖는 것이며, 그 길이는 1 내지 100mm, 바람직하게는 3 내지 40mm이며, 단면의 직경 또는 두께는 1 내지 50㎛, 바람직하게는 10 내지 40㎛이다. 상기 아라미드의 길이 및 직경 또는 두께는 목적하는 보수보강제 조성물의 품질, 내구 성능과 인장강도, 휨강도 및 인성 등에 따라 최적 범위로 조절할 수 있으며, 단일 형상을 유지하는 단일 길이 및 단일 직경으로 사용하는 것이 바람직하다.On the other hand, the aramid fiber has a single shape and its length is 1 to 100 mm, preferably 3 to 40 mm, and the diameter or thickness of the cross section is 1 to 50 탆, preferably 10 to 40 탆. The length and diameter or thickness of the aramid may be adjusted to an optimum range depending on the quality, durability, tensile strength, bending strength and toughness of the desired curing agent composition, and it is preferable to use the single length and the single diameter to maintain a single shape Do.
상기 아라미드에서 단일 형상이라 함은 길이 또는 직경 중 어느 하나라도 상이한 섬유가 혼합되지 않은 것을 의미하며, 보수보강제 조성물 내의 분산성 측면에서 단일 길이 및 단일 직경의 단일 형상을 갖는 것이 바람직하다.The single shape in the aramid means that no fibers having different lengths or diameters are mixed, and it is preferable that the aramid has a single shape having a single length and a single diameter in terms of dispersibility in the curing additive composition.
또한, 상기 아라미드는 5mm의 게이지 길이(gauge length)로 측정한 강도가 8.5g/d 이상, 바람직하게는 9.5g/d이상이고, 5mm의 게이지 길이로 측정한 신도가 60 내지 135%, 바람직하게는 75 내지 115%가 될 수 있다.
