Description
본 발명은 균열의 자가치유가 가능한 무기질 규산나트륨계를 이용한 콘크리트 단면복구 및 콘크리트 표면보수 공법에 관한 것으로, 보다 상세하게는 신설 또는 노후된 콘크리트 구조물의 표면에 존재하는 미세균열, 균열에 의한 파손, 내구성 저하를 억제하여 콘크리트 구조물의 강도, 방수성을 증대시키면서 중성화도 방지하고 보수 계면에서의 층분리를 억제하여 최적 상태로 부착강도를 높여 우수한 보수 및 방수 효과를 확보함으로써 콘크리트 구조물의 장수명화를 유지할 수 있도록 개선된 균열의 자가치유가 가능한 무기질 규산나트륨계를 이용한 콘크리트 단면복구 및 콘크리트 표면보수 공법에 관한 것이다.The present invention relates to a concrete cross-section restoration and concrete surface repair method using inorganic sodium silicate system capable of self-healing of cracks, and more particularly, to micro-crack existing on the surface of a new or old concrete structure, damage due to cracks, and durability. By suppressing deterioration, increasing the strength and waterproofness of the concrete structure, preventing neutralization, suppressing layer separation at the repair interface, and increasing the adhesion strength in an optimal state to ensure excellent repair and waterproofing effects to maintain the long life of the concrete structure. The present invention relates to a concrete section restoration and concrete surface repair method using an inorganic sodium silicate system capable of self-healing of improved cracks.
일반적으로, 기존 철근 콘크리트 구조물의 열화는 지진이나 외적 응력에 의한 것을 제외하면, 콘크리트 자체의 열화와 철근의 부식에 의한 문제이다.In general, the deterioration of the existing reinforced concrete structure is a problem due to the deterioration of the concrete itself and the corrosion of the reinforcing bar, except for earthquakes or external stress.
이와 같은 열화와 부식에 의한 문제의 원인은 이산화, 염소이온에 의한 염해, 물의 침투에 의한 용탈, 동해, 황산염의 침식, 알칼리에 대한 골재반응, 수축이나 균열 등이라 할 수 있으며, 이들이 단독 또는 복합적으로 혼재하면서 진행함으로써, 콘크리트의 열화와 철근의 부식 문제로 발현되어 콘크리트 구조물이 노후되고 수명이 단축되는 것이다.The causes of such deterioration and corrosion problems can be called dioxide, salt damage by chlorine ions, leaching by water penetration, freezing, erosion of sulfates, aggregate reaction to alkali, shrinkage or cracking, etc. By admixing and proceeding, the concrete structure is deteriorated and the lifespan is shortened due to the deterioration of concrete and corrosion of the rebar.
또한, 열화는 물을 매개로 한 화학적, 물리적 반응이며, 특히 중성화와 균열 등으로부터의 열화인자의 침입에 의해 콘크리트 구조물 내부에 있는 철근, 철골이 녹에 의해 부식이 진행되면, 그 체적 팽창에 의해 콘크리트의 내부가 외부보다 먼저 파괴되어 콘크리트 구조물의 강도를 저하시키거나 콘크리트의 탈락을 유도시키며, 나아가서는 콘크리트 구조물 전체가 파괴되는 등의 문제로 발전된다.In addition, deterioration is a chemical and physical reaction through water. In particular, when the reinforcing bars and steel frames inside the concrete structure undergo corrosion due to rust due to the intrusion of deterioration factors from neutralization and cracks, the volume expansion will cause the The inside of the concrete is destroyed before the outside, which reduces the strength of the concrete structure or induces the concrete to fall out, and furthermore, the entire concrete structure is destroyed.
이에 따라, 콘크리트 구조물의 표면보호 방법이나 보수 방법 또는 표면함침공법 등이 다양하게 시행되고 있다.Accordingly, various methods such as surface protection method, repair method, or surface impregnation method of concrete structures are being implemented.
이중에서 피복공법과 단면복구공법은 통상 열화가 진행되고 현저해진 단계에서 진행되기 때문에 보수 규모가 커져 보수비용이 많이 드는 단점이 있다.Among them, the coating method and the section restoration method have a disadvantage that the repair cost is high due to the large size of repair because it is usually progressed at a stage where deterioration progresses and becomes remarkable.
그리고, 표면함침공법은 예방보전형 유지보수공법으로서 보수비용도 비교적 저렴한 가격으로 효과적이지만, 실란계 표면함침재를 사용하기 때문에 방수성은 좋으나 자외선에 의한 열화, 철근 부식, 균열 억제, 중성화 억제 기능을 미약한 단점이 있다.In addition, the surface impregnation method is a preventive maintenance type maintenance method and is effective at a relatively low cost of repair. However, since it uses a silane-based surface impregnation material, it has good waterproofness, but it has the function of suppressing deterioration by ultraviolet rays, rebar corrosion, cracking, and neutralization. There is a slight drawback.
본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점들을 감안하여 이를 해결하고자 창출된 것으로, 신설 또는 노후된 콘크리트 구조물의 표면에 존재하는 미세균열, 균열에 의한 파손, 내구성 저하를 억제하여 콘크리트 구조물의 강도, 방수성을 증대시키면서 중성화도 방지하고 보수 계면에서의 층분리를 억제하여 최적 상태로 부착강도를 높여 우수한 보수 및 방수 효과를 확보함으로써 콘크리트 구조물의 장수명화를 유지할 수 있도록 개선된 균열의 자가치유가 가능한 무기질 규산나트륨계를 이용한 콘크리트 단면복구 및 콘크리트 표면보수 공법을 제공함에 그 주된 목적이 있다.The present invention was created to solve the problems in the prior art as described above, and the strength of the concrete structure by suppressing the micro-crack, breakage due to cracks, and decrease in durability existing on the surface of a new or old concrete structure, Inorganic material capable of self-healing of improved cracks to maintain the long life of concrete structures by securing excellent repair and waterproofing effect by increasing the adhesion strength in an optimal state by preventing neutralization while increasing waterproofness and suppressing layer separation at the repair interface Its main purpose is to provide a concrete section restoration and concrete surface repair method using sodium silicate.

이를 위해 본 발명은 도 1 및 도 2의 예시와 같이, 바탕면 세척단계, 내산제 분무단계, 완전 건조단계, 방수 및 보수액 분무단계, 마감액 처리단계 및 건조 경화단계를 포함한다.To this end, the present invention includes a base surface washing step, an acid-resistant spray step, a complete drying step, a waterproofing and repair solution spraying step, a finishing liquid treatment step, and a drying curing step, as illustrated in FIGS. 1 and 2.
이때, 바탕면 세척단계는 처리해야할 면을 깨끗하게 청소하여 이물이 없도록 하는 단계이다.At this time, the step of washing the background surface is a step in which the surface to be treated is cleaned so that there are no foreign substances.
그리고, 내산제 분무단계는 처리면의 산화억제 및 자외선에 의한 열화현상을 억제하기 위해 내산제를 분무하는 단계이다.In addition, the acid-resistant spraying step is a step of spraying an acid-resistant agent to inhibit oxidation of the treated surface and suppress deterioration due to ultraviolet rays.
이 경우, 상기 내산제는 로진(Rosin) 3중량%와, 수성 라텍스 25중량%와, 콜타르 2.5중량%와, BHT(Butylated HydroxyToluene) 4.5중량%와, 폴리부텐 4중량%와, 세레신 1.5중량%와, 포졸란 1.0중량% 및 나머지 물로 이루어진다.In this case, the acid resistance is rosin (Rosin) 3% by weight, aqueous latex 25% by weight, coal tar 2.5% by weight, BHT (Butylated HydroxyToluene) 4.5% by weight, polybutene 4% by weight, and ceresin 1.5% by weight Wow, 1.0% by weight of pozzolan and the rest of water.
여기에서, 로진(Rosin)은 송진을 수증기로 증류하여 테레빈유를 제거한 다음에 남는 담황색 또는 갈색의 투명한 액체로서 성분간 결합성을 강화시키면서 점도를 조절하며 수용성 라텍스에 접착력을 부여하기 위해 첨가된다.Here, rosin is a pale yellow or brown transparent liquid that remains after removing turpentine by distilling rosin with water vapor, and is added to adjust viscosity while strengthening the binding properties between components, and to impart adhesion to water-soluble latex.
또한, 상기 콜타르는 균열억제 및 방수성능 강화를 위해 첨가되며, 상기 BHT(Butylated HydroxyToluene)는 고무성분이 자외선, 열 또는 공기 등에 의하여 자연 산화 또는 노화되는 현상을 억제시켜 접착력의 열화를 방지하기 위해 첨가된다.In addition, the coal tar is added to inhibit cracking and reinforce waterproof performance, and the BHT (Butylated HydroxyToluene) is added to prevent deterioration of adhesion by inhibiting natural oxidation or aging of rubber components due to ultraviolet rays, heat, or air. do.
아울러, 폴리부텐은 점액성 라텍스를 부드럽게 하여 고무성분의 연화를 높이고 인장강도를 증대시키며 계면 부착력을 강화시켜 계면 분리를 억제하기 위해 첨가된다.In addition, polybutene is added to soften the mucous latex to increase the softening of the rubber component, increase the tensile strength, and strengthen the interfacial adhesion to suppress interface separation.
뿐만 아니라, 상기 세레신(Ceresin)은 결합력을 증대시키고 유화안정화를 유도하여 크랙 발생을 억제하고, 이를 통해 찢어짐을 방지하기 위해 첨가된다.In addition, the ceresin (Ceresin) is added to increase the binding force and induce emulsion stabilization to suppress the occurrence of cracks, and thereby prevent tearing.
아울러, 상기 포졸란은 내산성, 내부식성 및 방수성을 확보하기 위해 인공 포졸란이 아닌 화산회에서 취득한 입도 0.001mm 이하의 천연포졸란을 사용한다.In addition, the pozzolan is not an artificial pozzolan, but a natural pozzolan having a particle size of 0.001mm or less obtained from volcanic ash in order to secure acid resistance, corrosion resistance and waterproofness.
그리고, 완전 건조단계는 상기 내산제를 분무하고 난 후 방수 및 보수액을 바로 분무하게 되면 반응에 따른 색변이 발생할 수 있기 때문에 이를 방지하기 위해 충분히 시간을 두고 완전히 경화시키는 단계이다. 바람직하게는 12시간 유지하여 완전건조시킨다.In addition, the complete drying step is a step of completely curing with a sufficient time to prevent this, because if the acid-resistant agent is sprayed and then the waterproofing and repairing solution is sprayed immediately, color change according to the reaction may occur. Preferably, it is kept for 12 hours to completely dry.
한편, 방수 및 보수액 분무단계는 아질산염 수용액과 규산나트륨 수용액을 1:1의 부피비로 혼합한 액을 3-4회 스프레이하는 단계이다.Meanwhile, the spraying step of waterproofing and water-retaining solution is a step of spraying a solution obtained by mixing an aqueous nitrite solution and an aqueous sodium silicate solution in a volume ratio of 1:1 3-4 times.
이때, 상기 아질산염 수용액은 아질산염을 물로 10배 희석한 수용액을 말하는데, 이는 위험도를 낮추기 위한 것이다.At this time, the nitrite aqueous solution refers to an aqueous solution obtained by diluting nitrite by 10 times with water, which is to lower the risk.
이러한 아질산염은 니트로에탄의 이성질체로서 알카리성이며, 중성화를 억제한다.Such nitrite is an isomer of nitroethane, which is alkaline and inhibits neutralization.
특히, 아질산염은 철근에 대한 방청효과가 뛰어나며, 염분 농도가 높은 기설 콘크리트에 대해서도 우수한 방청효과도 제공한다.In particular, nitrite has an excellent anti-corrosive effect for reinforcing bars, and also provides an excellent anti-corrosive effect for existing concrete with a high salt concentration.
그리고, 상기 규산나트륨 수용액은 중성화된 콘크리트의 표면장력을 저하시켜 침투력을 향상시키기 위해 사용된다.In addition, the sodium silicate aqueous solution is used to improve penetration by lowering the surface tension of the neutralized concrete.
이러한 규산나트륨 수용액은 규산나트륨 35중량%와, 리튬 10중량%와, 실리케이트 10중량%와, 식초 25중량% 및 나머지 물로 이루어진다.This sodium silicate aqueous solution consists of 35% by weight of sodium silicate, 10% by weight of lithium, 10% by weight of silicate, 25% by weight of vinegar and the rest of water.
이중에서, 리튬은 콘크리트 표면에서 알카리를 중화시킴으로써 침투력을 확보하기 위해 첨가되며; 상기 규산나트륨은 식초와 함게 반응하면서 리튬에 의해 확보된 콘크리트 공극내로 약 10~20mm 침투된 후 유리알카리 또는 수산화칼슘과 반응하여 불용성의 C-S-H 겔을 형성하고 이를 통해 공극을 조밀화, 내수화시켜 균열이 생기지 않도록 억제하고, 강력한 접착력을 확보하도록 하게 된다. 이때, 실리케이트는 피복되어 산화를 방지한다.Among them, lithium is added to ensure penetration by neutralizing alkali on the concrete surface; The sodium silicate reacts with vinegar and penetrates about 10 to 20 mm into the concrete pores secured by lithium, and then reacts with free alkali or calcium hydroxide to form an insoluble CSH gel, through which the pores are densified and hydrated to prevent cracks. And to secure a strong adhesive force. At this time, the silicate is coated to prevent oxidation.
이와 같은 규산나트륨 수용액은 아질산염 수용액과 반응하면서 콘크리트의 공극, 크랙, 균열 부위로 침투, 충진되면서 겔화되어 치밀화시키게 된다.The sodium silicate aqueous solution reacts with the nitrite aqueous solution and penetrates and fills the voids, cracks, and cracks of the concrete, resulting in gelation and densification.
특히, 규산나트륨 수용액은 후술되는 마감액을 끌고 들어가 충진, 치밀화를 촉진하기 때문에 자가복귀 기능을 수행하게 되어 매우 건실하고 안정적이면서 높은 방수성, 높은 인장강도와 압축강도를 유지하여 내구성을 높이게 되고, 나아가 중성화억제 및 방청기능 강화로 콘크리트 구조물의 장수명화를 달성하게 된다.In particular, the sodium silicate aqueous solution attracts the finishing solution described later and promotes filling and densification, so it performs a self-recovery function, which is very robust and stable, and maintains high waterproofness, high tensile strength and compressive strength to increase durability. The long life of concrete structures is achieved by reinforcing neutralization and rust prevention functions.
아울러, 마감액 처리단계는 처리면에 마감용으로 도포되는 조성물을 도포하는 단계로서, 상기 마감액은 에칠렌글리콜디아세테이트 25중량%와, 우레아 10중량%와, 풀러렌 순지트 분말 5중량%와, 페닐트리메톡시실란 5중량%와, 수용성 아크릴수지 15중량% 및 나머지 물로 이루어진다.In addition, the finishing liquid treatment step is a step of applying a composition applied for finishing on the treated surface, the finishing liquid is 25% by weight of ethylene glycol diacetate, 10% by weight of urea, 5% by weight of fullerene purezit powder, It consists of 5% by weight of phenyltrimethoxysilane, 15% by weight of a water-soluble acrylic resin, and the rest of water.
이때, 상기 에칠렌글리콜디아세테이트는 알카리 하에서 초산을 생성하면서 중화작용에 의해 규산나트륨을 겔화시킨다. 때문에, 상기 규산나트륨 수용액이 완전건조가 아닌 반건조 상태일 때 마감액을 분무해야 한다. At this time, the ethylenic glycol diacetate gelates sodium silicate by neutralization while generating acetic acid under alkali. Therefore, when the sodium silicate aqueous solution is in a semi-dry state rather than completely dry, the finishing solution must be sprayed.
그리고, 상기 우레아는 공융점 형성에 따른 축열성 강화 기능이 있고, 뛰어나 보온지속력이 높고, 페닐트리메톡시실란은 빙결 저해성이 높아 결빙을 억제하는데 매우 효과적이다. 따라서, 결빙이 생기지 않도록 하는데 유의점이 있다.In addition, the urea has a heat-storage reinforcement function according to the formation of a eutectic point, excellent thermal insulation persistence is high, and phenyltrimethoxysilane is very effective in inhibiting freezing due to high freezing inhibition. Therefore, there is a point to keep in mind to prevent freezing.
또한, 상기 풀러렌 순지트 분말은 풀러렌(fullerene)이 60% 이상 함유되고 0.5㎛ 입도를 갖는 순지트(shungite) 분말을 사용해야 하며, 순지트는 규산염과 풀러렌이 주로 함유된 천연 광물을 말하고, 풀러렌(fullerene)이란 탄소의 3번째 동소체로서 탄소의 다른 동소체인 다이아몬드와 흑연의 경우 탄소 원자들이 무한히 배열되어 있는 고체인데 반해, 유한한 분자로 분자식은 C60이고, 지구상의 항산화물질중 가장 강력한 것으로서 이러한 강력한 항산화력을 이용하여 시공면에서의 곰팡이 등 세균 활성이나 증식을 억제하기 위해 첨가된다.In addition, the fullerene purezit powder should contain more than 60% of fullerene and use a shungite powder having a particle size of 0.5㎛, and the pureerene refers to a natural mineral mainly containing silicate and fullerene, and fullerene ) is inde as the third allotrope of carbon for the other allotropes of carbon diamond and graphite carbon atoms are solids that are infinitely array hand, and by the finite molecular molecular formula is C 60, such a powerful antioxidant as the most powerful of the antioxidants of the earth It is added to suppress the activity or proliferation of bacteria such as mold on the construction surface by using force.
즉, 세균이나 균류의 증식은 결국, 균열이 원인이 되기 때문에 분무 도포시 아예 이러한 균류의 증식 자체를 차단하기 위함이다.In other words, the growth of bacteria or fungi is eventually caused by cracks, so it is to block the growth of these fungi at all when sprayed.
아울러, 상기 수용성 아크릴수지는 우수한 점착력과 방수성을 제공하기 위해 첨가된다.In addition, the water-soluble acrylic resin is added to provide excellent adhesion and waterproofness.
이후, 건조 경화단계가 수행되는데, 이는 충분히 말려 경화시킴으로써 방수 및 단면보수 작업을 마무리하는 단계이다.Thereafter, a dry curing step is performed, which is a step of finishing the waterproofing and cross-section repair work by sufficiently drying and curing.
이에 더하여, 본 발명에서는 완전 건조단계 후 방수 및 보수액 분무단계 전에 보호액 분무단계를 더 수행할 수 있다.In addition, in the present invention, after the complete drying step, the protective solution spraying step may be further performed before the waterproofing and water-retaining solution spraying step.
상기 보호액 분무단계는 물과 피로인산나트륨과 잔탄검을 8:1.5:0.5의 중량비로 혼합한 보호액을 분무하여 건조된 내산제 도막과 방수 및 보수도막 상호간의 상분리가 일어나지 않도록 하는 단계이다.The protective liquid spraying step is a step of spraying a protective liquid obtained by mixing water, sodium pyrophosphate, and xanthan gum in a weight ratio of 8:1.5:0.5 to prevent phase separation between the dried acid-resistant coating film and the waterproofing and repairing coating.
여기에서, 상분리란 도포된 막의 경계면에서의 층분리를 의미하며, 이것은 후처리된 도막이 들떠 올라 분리됨으로써 열화, 방수성 저하 등의 원인이 되기 때문에 이를 차단하기 위한 것이다.Here, the phase separation means layer separation at the interface of the applied film, and this is to block the post-treated coating film because it lifts up and separates, causing deterioration and lowering of water resistance.
이를 위해, 물에 혼합된 피로인산나트륨과 잔탄검은 계면에서의 층분리를 억제하는데 매우 효과적인 기능을 제공한다. 즉, 일종의 앵커링 기능을 강화시킨다.To this end, sodium pyrophosphate and xanthan gum mixed in water provide a very effective function to inhibit layer separation at the interface. In other words, it strengthens a kind of anchoring function.
뿐만 아니라, 상기 아질산염 수용액을 만들 때 아질산염 수용액 100중량부에 대해 PCM수(水) 20중량부를 더 첨가할 수 있다.In addition, when preparing the nitrite aqueous solution, 20 parts by weight of PCM water may be further added to 100 parts by weight of the nitrite aqueous solution.
이때, PCM수는 PCM(Phase Change Material) 30중량%, 아세트산나트륨 40중량% 및 나머지 물로 이루어지며, PCM은 일정온도를 기준으로 물질의 상태가 변화하면서 열(잠열)을 흡수 또는 방출하는 물질로서 테트라데칸, 옥타데칸, 노나데칸 중에서 선택된 어느 하나를 사용할 수 있고, 외부온도가 상승하여 고유의 용융점 이상이 되면 고체 상태에서 액체 상태로 바뀌면서 일정한 양의 열을 흡수하고, 외부온도가 하락하여 고유의 용융점 이하게 되면 액체 상태에서 고체 상태로 바뀌면서 저장한 열을 방출하는 원리를 가진 물질이다.At this time, PCM water consists of 30% by weight of PCM (Phase Change Material), 40% by weight of sodium acetate, and the rest of water, and PCM is a material that absorbs or releases heat (latent heat) while changing the state of the material based on a certain temperature. You can use any one selected from tetradecane, octadecane, and nonadecane, and when the external temperature rises and becomes higher than its own melting point, it changes from a solid state to a liquid state, absorbing a certain amount of heat, and the external temperature decreases It is a substance with the principle of releasing stored heat by changing from a liquid state to a solid state when it reaches the melting point.
또한, 이러한 PCM에 아세트산나트륨(Sodium acetate)을 혼합하는 이유는 상변화시 열방출 효율을 높이기 위한 것이다. 이와 같은 조합을 통해 방수성을 더욱 강화시키면서 혹서기 열팽창을 억제하고, 혹한시 열수축을 극소화시켜 균열, 크랙, 갈라짐, 파단, 들뜸을 억제하는데 매우 효과적으로 작용할 수 있다.In addition, the reason for mixing sodium acetate with the PCM is to increase the heat dissipation efficiency during phase change. Through such a combination, it can be very effective in suppressing thermal expansion during hot weather while further strengthening waterproofness, and minimizing thermal contraction during cold weather to suppress cracks, cracks, cracks, fractures, and lifts.
