Abstract
본 발명은 무수축 미장 몰탈 조성물 및 그 시공방법에 관한 것으로서, 콘크리트 균열부위의 보수가 보다 신속하게 이루어짐과 함께 부착력을 개선시키고 수축 현상을 방지하는 효과를 나타내기 위한 것이다.
이를 실현하기 위한 본 발명의 무수축 미장 몰탈 조성물은, 규사 40~60중량%, 포틀랜드 시멘트, 20~40중량%, CSA(칼슘설포알루미네이트) 1~10중량%, 폴리우레아 1~5중량%, 무수석고 1~5중량%, 탄산칼슘 1~3중량%의 혼합 조성을 이루는 것을 특징으로 한다.The present invention relates to a non-shrinkage plastering mortar composition and its construction method, and is intended to provide the effect of more quickly repairing concrete cracks, improving adhesion, and preventing shrinkage.
The non-shrinkage plastering mortar composition of the present invention for realizing this includes 40 to 60% by weight of silica sand, 20 to 40% by weight of Portland cement, 1 to 10% by weight of CSA (calcium sulfoaluminate), and 1 to 5% by weight of polyurea. It is characterized by a mixed composition of 1 to 5% by weight of anhydrous gypsum and 1 to 3% by weight of calcium carbonate.
Description
본 발명은 무수축 미장 몰탈에 관한 것으로서, 더욱 상세하게는 콘크리트 벽면이나 바닥 균열부위, 각종 PC보수 및 미장사춤용으로 사용되는 무수축 미장 몰탈 조성물 및 그 시공방법에 관한 것이다.The present invention relates to a non-shrinking plastering mortar, and more specifically, to a non-shrinking plastering mortar composition and a construction method thereof used for concrete wall or floor cracks, various PC repairs, and plastering.
일반적으로 콘크리트 구조물에서 열화 등에 의해 콘크리트에 균열이 발생하여 시간이 지나게 되면 콘크리트의 압축강도와 철근의 인장강도가 점차 떨어지게 되고, 균열 부위로 통해 노출된 콘크리트는 중성화 현상이 진행되어 철근의 부식이 일어난다. 이러한 철근의 부식 현상이 심해지면 콘크리트 구조물이 결국 붕괴될 수도 있다.Generally, cracks occur in concrete due to deterioration in concrete structures, and over time, the compressive strength of the concrete and the tensile strength of the rebar gradually decrease, and the concrete exposed through the crack undergoes a neutralization phenomenon, causing corrosion of the rebar. . If this corrosion phenomenon of rebar becomes severe, the concrete structure may eventually collapse.
따라서, 콘크리트 구조물이 열화 되어 균열이 발생하면 조속하게 열화된 부위를 보수할 필요가 있다.Therefore, when a concrete structure deteriorates and cracks occur, it is necessary to promptly repair the deteriorated area.
이러한 균열은 시멘트가 응결되는 과정에서 수축에 의해 발생하는 것으로, 시멘트의 구성성분, 시멘트의 분말도, 물의 양 등에 가장 큰 영향을 받는다. 시멘트의 수축균열을 방지하기 위해 건조수축을 보상하는 정도로 팽창할 수 있는 팽창시멘트를 사용하는 방법이 알려져 있다.These cracks occur due to shrinkage during the cement hardening process, and are most affected by the composition of the cement, cement fineness, and the amount of water. To prevent shrinkage cracking of cement, there is a known method of using expanded cement that can expand to a degree that compensates for drying shrinkage.
그런데 지금까지 알려진 팽창시멘트는 그 제조과정이 복잡하고 부착력이 낮으며, 환경오염물질이 함유되어 있어서 인체에 유해성이 작용하는 등의 문제점이 있었다.However, the expanded cement known so far has problems such as a complicated manufacturing process, low adhesion, and harmful effects on the human body because it contains environmental pollutants.

도 1은 본 발명의 일 실시 예에 따른 무수축 미장 몰탈 시공과정 순서도.Figure 1 is a flowchart of the non-shrinkage plastering mortar construction process according to an embodiment of the present invention.
이하, 본 발명의 구체적인 실시 예를 살펴보기로 한다.Hereinafter, we will look at specific embodiments of the present invention.
본 발명의 실시 예는 여러 가지 형태로 변형될 수 있으며, 본 발명의 범위가 아래에서 상세히 설명하는 실시 예로 한정되는 것으로 해석되어서는 안 된다. 본 실시 예는 당 업계에서 평균적인 지식을 가진 자에게 본 발명을 더욱 완전하게 설명하기 위하여 제공되는 것이다.Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. This example is provided to more completely explain the present invention to those with average knowledge in the art.
따라서, 본 상세한 설명에서 표현한 기술특징 등은 더욱 명확한 설명을 강조하기 위해서 과장되어 표현될 수 있다. 또한, 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 공지 기술의 기능 및 구성에 관한 상세한 설명은 생략될 수 있다.Accordingly, technical features, etc. expressed in this detailed description may be exaggerated to emphasize a clearer description. Additionally, detailed descriptions of the functions and configurations of known technologies that are judged to unnecessarily obscure the gist of the present invention may be omitted.
먼저, 본 발명의 일 실시 예에 따른 무수축 미장 몰탈 조성물을 살펴보면 다음과 같다.First, looking at the non-shrinkage plastering mortar composition according to an embodiment of the present invention, it is as follows.
본 실시 예에서의 몰탈 조성은, 규사 40~60중량%, 포틀랜드 시멘트, 20~40중량%, CSA(칼슘설포알루미네이트) 1~10중량%, 폴리우레아 1~5중량%, 무수석고 1~5중량%, 탄산칼슘 1~3중량%의 비율로 혼합 조성을 이루도록 하였다.The mortar composition in this example is 40 to 60% by weight of silica sand, 20 to 40% by weight of Portland cement, 1 to 10% by weight of CSA (calcium sulfoaluminate), 1 to 5% by weight of polyurea, and 1 to 1% of anhydrous gypsum. The mixed composition was made at a ratio of 5% by weight and 1 to 3% by weight of calcium carbonate.
이때, 혼합 조성물 중 폴리우레아는 몰탈층의 탄력성을 향상시키는 기능을 수행하게 된다.At this time, polyurea in the mixed composition performs the function of improving the elasticity of the mortar layer.
이와 같은 조성을 이루는 무수축 미장 몰탈의 시공과정 및 그에 따른 작용효과를 살펴보면 다음과 같다.The construction process and resulting effects of the non-shrinking plastering mortar of this composition are as follows.
본 발명의 몰탈 조성물은 콘크리트 벽면이나 바닥 균열부위, 각종 PC보수 및 미장사춤 용도로 사용이 이루어지게 되며, 사용 시 물과 적절한 비율로 혼합하여 페이스트 상태로 사용이 이루어지게 된다.The mortar composition of the present invention is used for concrete wall or floor cracks, various PC repairs, and plastering purposes. When used, it is mixed with water in an appropriate ratio and used in a paste state.
즉, 도 1의 순서도에서와 같이 미장 몰탈을 콘크리트 균열부위에 바르거나 주입 후 5~10분 동안 히터봉 등을 이용하여 70~90℃의 열을 몰탈 표면에 가하게 된다.That is, as shown in the flow chart of FIG. 1, the plastering mortar is applied to the concrete crack area or after injection, heat of 70 to 90°C is applied to the mortar surface using a heater rod, etc. for 5 to 10 minutes.
이후, 몰탈 표면에 벤질알코올이 혼합된 약액을 분사하여 박막의 코팅층을 형성시키게 된다.Afterwards, a chemical solution mixed with benzyl alcohol is sprayed on the mortar surface to form a thin coating layer.
이때 분사되는 약액은 카보머 20~40중량%, 벤질알코올 10~30중량%, 디에틸에테르 10~30중량%, 플루오르화가돌리늄 10~30중량% 비율의 혼합 조성을 이룸이 바람직하다.At this time, the sprayed chemical solution preferably has a mixed composition of 20 to 40% by weight of carbomer, 10 to 30% by weight of benzyl alcohol, 10 to 30% by weight of diethyl ether, and 10 to 30% by weight of dolinium fluoride.
이와 같은 과정을 통해 시공이 이루어지게 되면 균열 부위에 충전된 본 발명의 무수축 미장 몰탈로 인하여, 콘크리트 균열부위의 보수가 보다 신속하게 이루어짐과 함께 가열 작용에 따른 부착력을 개선시키고 수축 현상을 방지하는 효과를 나타내게 된다.When construction is carried out through this process, the non-shrinking plastering mortar of the present invention filled in the crack area allows repair of the concrete crack area more quickly, improves adhesion due to heating, and prevents shrinkage. It shows effect.
특히, 몰탈 표면에 약액 코팅층이 형성되어지게 되면 카보머 및 벤질알코올 작용으로 인해 급격한 몰탈의 보호 기능이 수행되어 몰탈 재료의 유동성 및 속건성이 개선되고, 디에틸에테르는 코팅층의 점도를 유지하여 전체적으로 균일한 박막의 두께로 약액 코팅층이 형성되도록 하며, 플루오르화가돌리늄은 몰탈 표면의 오염방지 및 살균 기능을 수행하는 이점을 나타낸다.In particular, when a chemical coating layer is formed on the mortar surface, the protective function of the mortar is rapidly performed due to the action of carbomer and benzyl alcohol, improving the fluidity and quick drying of the mortar material, and diethyl ether maintains the viscosity of the coating layer to ensure uniformity throughout. A chemical coating layer is formed with a thickness of one thin film, and dolinium fluoride has the advantage of preventing contamination and sterilizing the mortar surface.
한편, 본 발명의 다른 실시 예로는 상기 무수축 몰탈 조성물에 산화세슘, 벤토나이트, 폴리유산, 브로민, 이산화규소, 알릴 메타크릴레이트가 각각 1~3중량%의 비율로 첨가된다.Meanwhile, in another embodiment of the present invention, cesium oxide, bentonite, polylactic acid, bromine, silicon dioxide, and allyl methacrylate are each added to the non-shrinkage mortar composition at a ratio of 1 to 3% by weight.
즉 이때에는 규사 40~60중량%, 포틀랜드 시멘트, 20~40중량%, CSA(칼슘설포알루미네이트) 1~10중량%, 폴리우레아 1~5중량%, 무수석고 1~5중량%로 혼합이 이루어짐과 함께 탄산칼슘, 산화세슘, 벤토나이트, 폴리유산, 브로민, 이산화규소, 알릴 메타크릴레이트 성분이 각각 1~3중량%로 첨가됨이 바람직하다.That is, at this time, it is mixed with 40 to 60% by weight of silica sand, 20 to 40% by weight of Portland cement, 1 to 10% by weight of CSA (calcium sulfoaluminate), 1 to 5% by weight of polyurea, and 1 to 5% by weight of anhydrous gypsum. It is preferable that calcium carbonate, cesium oxide, bentonite, polylactic acid, bromine, silicon dioxide, and allyl methacrylate components are added in an amount of 1 to 3% by weight, respectively.
이와 같은 조성을 이루게 되면 몰탈의 변색 및 내부 공극 발생을 방지하여 몰탈 품질을 향상시킬 수 있게 된다.When such a composition is achieved, mortar quality can be improved by preventing discoloration of the mortar and the occurrence of internal voids.
특히, 산화세슘은 몰탈의 내화성을 강화하여 백화 현상을 방지하고, 벤토나이트 및 폴리유산은 수팽창력 향상과 함께 부착력을 강화하여 입자 상호간의 안정적인 결합상태를 이루게 되며, 브로민 및 이산화규소는 몰탈 내구성 및 강도 향상에 따른 크랙 발생을 방지하고, 알릴 메타크릴레이트는 CSA 성분의 활성화에 따른 수축 방지효과를 극대화할 수 있게 된다.In particular, cesium oxide strengthens the fire resistance of the mortar and prevents whitening, bentonite and polylactic acid improve water expansion and strengthen adhesion to achieve a stable bond between particles, and bromine and silicon dioxide improve mortar durability and The occurrence of cracks due to improved strength is prevented, and allyl methacrylate can maximize the anti-shrinkage effect due to activation of the CSA component.

Although specific embodiments of the present invention have been described and shown above, it is obvious that the non-shrinkage plastering mortar technology of the present invention can be implemented in various modifications by those skilled in the art.
예를 들면, 상기 실시 예에서는 무수축 몰탈의 특정한 성분 혼합 조성이 설명되었으나 필요에 따라서는 기능성 향상을 위한 추가적인 기타성분이 혼합될 수 있게 된다.For example, in the above embodiment, the specific mixing composition of the non-shrinkage mortar was described, but if necessary, additional other ingredients can be mixed to improve functionality.
또한, 시공과정에 있어서도 건조시간이나 온도 등은 현장 상황 및 계절에 따라 세팅될 수 있게 된다.Additionally, during the construction process, drying time and temperature can be set according to site conditions and seasons.
따라서 이와 같은 변형된 실시 예들은 본 발명의 기술적 사상이나 범위로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시 예들은 본 발명의 첨부된 특허청구범위 내에 포함된다 해야 할 것이다.Therefore, such modified embodiments should not be understood individually from the technical spirit or scope of the present invention, and such modified embodiments should be included within the scope of the appended claims of the present invention.
