Description
본 발명은 내구성 및 내화학성을 개선한 무기질계 세라믹 보수 몰탈 조성물에 관한 것이다.
The present invention relates to an inorganic ceramic repair mortar composition having improved durability and chemical resistance.
콘크리트 구조물과 포장 도로 등은 공기 및 물과 오랜 기간 동안 접촉되어 열화되고, 과도한 하중을 받거나 수해 등으로 인하여 파손되는 경우가 많으므로 이들을 부분적으로 보수할 필요성이 있게 된다. 공기와 물에 의한 열화 현상은 중성화, 염해, 기온에 따른 수축팽창 등에 기인하게 되는데 이러한 열화 현상으로 인해 철근부식, 균열, 박리 등을 가져와 구조물을 파괴시키게 된다. 따라서 이들을 보수하지 않으면 안 되는 상황에 처하게 된다. Concrete structures, pavements, and the like are degraded by contact with air and water for a long time, and are often damaged due to excessive load or flooding, so there is a need to partially repair them. The degradation caused by air and water is caused by neutralization, salt damage, shrinkage expansion according to temperature, and the like, which causes reinforcement corrosion, cracking, peeling, etc., and destroys the structure. Therefore, they are in a situation where they must be repaired.
이와 같이 부분적으로 파손된 구조물을 보수하기 위해서 대개 보수용 몰탈을 사용하게 되는 데, 일반적으로 사용되는 보수 몰탈은 시멘트, 규사, 실리카흄(fumed silica) 및 증점제로 이루어져 있어 보수 용도로만 사용되고, 내구성, 염해 방지성, 내화학성에 있어서 미흡한 점이 많이 있었다.
In order to repair such partially damaged structures, repair mortar is usually used. The repair mortar generally used is composed of cement, silica sand, fumed silica, and thickener, and is used only for repair purposes. There were many insufficiency in prevention and chemical resistance.
이러한 몰탈로 보수를 하는 경우 그 수명이 짧고 원 모체 콘크리트를 보호하는 기능이 약한 문제점이 있다.In the case of repairing with such mortar, its life is short and there is a problem in that the function of protecting the raw concrete is weak.
이에 본 발명자들은 상기한 문제점들을 해결할 수 있는 보수 몰탈을 개발하기 위해 계속 연구를 진행하던 중 특정 구성의 세라믹을 첨가함으로써 종래의 보수 몰탈의 성질을 유지하면서 내구성, 염해 방지성, 내화학성을 증진시킬 수 있다는 사실을 알아내고 본 발명을 완성하기에 이르렀다.Therefore, the present inventors continue to research to develop a repair mortar that can solve the above problems, while adding a ceramic of a specific configuration to improve the durability, salt resistance and chemical resistance while maintaining the properties of the conventional repair mortar It has been found that the invention can be completed and the present invention has been completed.
따라서 본 발명의 목적은 내구성, 중성화 방지성, 염해 방지성, 내화학성을 증진시킨 무기질계 세라믹 보수 몰탈을 제공하는 데 있다.

본 발명에서 사용되는 기술 용어 및 과학 용어에 있어서 다른 정의가 없다면, 이 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 통상적으로 이해하고 있는 의미를 갖는 것으로 해석될 수 있다.The technical terms and scientific terms used in the present invention can be construed as meaning ordinary meanings understood by those of ordinary skill in the art without departing from the scope of the present invention.
본 발명에서 사용되는 포틀랜드 시멘트는, 조성물 총 100 중량부를 기준으로, 30 내지 50 중량부의 양으로 사용된다. 30 중량부 미만의 양으로 사용하면 요구되는 강도가 저하되는 문제점이 있으며, 50 중량부를 초과하면 몰탈에 크랙이 발생되는 문제점이 있다. Portland cement used in the present invention is used in an amount of 30 to 50 parts by weight, based on 100 parts by weight of the total composition. When used in an amount less than 30 parts by weight, there is a problem that the required strength is lowered, and when it exceeds 50 parts by weight, there is a problem that cracks occur in mortar.
본 발명에서 사용되는 규사는, 조성물 총 100 중량부를 기준으로, 40 내지 65.94 중량부의 양으로 사용된다. 40 중량부 미만의 양으로 사용하면 몰탈에 크랙이 발생되는 문제점이 있으며, 65.94 중량부를 초과하면 요구하는 강도가 저하되는 문제점이 있다. The silica sand used in the present invention is used in an amount of 40 to 65.94 parts by weight based on 100 parts by weight of the total composition. When used in an amount of less than 40 parts by weight, there is a problem that cracks occur in mortar, and when it exceeds 65.94 parts by weight, there is a problem that the required strength is lowered.
본 발명에서는 종래에 사용되던 실리카흄을 사용하지 않고, 그 대신 고령토를 소성온도 1250 ℃ 내지 1400 ℃에서 7 내지 9 시간 동안 반응시켜 얻은 메타카올린을 사용한다. 이때 고령토를 상기와 같이 고온에서 소성시켜 얻는 메타카올린으로 만들어 사용하지 않으면, 본 발명에서 목적으로 하는 효과를 얻을 수가 없다. 그런데 여기서 단기적으로는 에트린자이트(ettringite)의 생성과 시멘트 중의 C3S의 활성화로 인해 초기 강도가 증가되며, 중장기적으로는 시멘트의 수산화칼슘과 포졸란 반응(수경성을 가지는 실리케이트 또는 알루미네이트 성분을 생성하는 반응)을 일으킨다. In the present invention, the silica fume used in the prior art is not used. Instead, metakaolin obtained by reacting kaolin at a firing temperature of 1250 ° C to 1400 ° C for 7 to 9 hours is used. In this case, if the kaolin is not made of metakaolin obtained by calcining at a high temperature as described above and not used, the effect desired in the present invention cannot be obtained. However, in the short term, the initial strength is increased due to the formation of ettringite and the activation of C 3 S in cement. Reaction to produce).
포졸란 물질의 직접적인 반응 참여는 수화반응이 시작되고 나서 3일 내지 14일 경과한 다음에 본격적으로 시작된다. 포졸란 물질부터 용출된 Si 이온 과 Al 이온은 공극에 존재하는 세공액에 포함된 Ca 이온과 반응하여 CSH 상 및 칼슘 알루미늄 수화물을 형성하여 경화체의 조직을 치밀하게 만들어 준다.Participation in the direct reaction of pozzolanic material begins in earnest three to fourteen days after the hydration reaction begins. Si ions and Al ions eluted from the pozzolanic material react with Ca ions in the pore solution present in the pores to form CSH phase and calcium aluminum hydrate to make the structure of the cured body dense.
본 발명에서 사용되는 메타카올린은 비표면적이 11,000 내지 13,000 g/cm2이어야 한다. 비표면적이 11,000 g/cm2 미만이면, 몰탈 밀도가 떨어지므로 중성화 염해 방지 성능과 같은 몰탈의 기능성이 떨어지는 문제점이 있으며, 13,000 g/cm2를 초과하면 상기와 같은 몰탈의 기능성은 상승하지만 고 분말로 인하여 원가 상승 이라는 문제점이 발생한다.The metakaolin used in the present invention should have a specific surface area of 11,000 to 13,000 g / cm 2 . If the specific surface area is less than 11,000 g / cm 2 , there is a problem that the mortar density, such as the neutralization salt prevention performance is inferior because the mortar density is lowered, and if the specific surface area exceeds 13,000 g / cm 2 , but the functionality of the mortar as mentioned above is high powder This raises the problem of cost increase.
본 발명에서 사용되는 메타카올린은, 다음과 같은 구성 성분과 조성비(중량비)를 갖는다:Metakaolin used in the present invention has the following components and composition ratio (weight ratio):
SiO2 58%, Al2O3 37%, Fe2O3 2.4 %, CaO 0.2%, MgO 0.3%, K20 0.8%, SiO 2 58%, Al 2 O 3 37%, Fe 2 O 3 2.4%, CaO 0.2%, MgO 0.3%, K 2 0 0.8%,
Na2O 0.2%.Na 2 O 0.2%.
본 발명에서 사용되는 세라믹 규사는 분말형이며, 카올리나이트와 할로이사이트가 있다. 카올리나이트는 Al2O3.2SiO2.2H2O로 구성되어 있으며, 할로이사이트는 Al2O3ㆍSiO2ㆍ4H2O로 구성되어 있다. Ceramic silica sand used in the present invention is powder type, and there are kaolinite and halosite. Kaolinite is composed of Al 2 O 3 .2SiO 2 .2H 2 O , and halloysite is composed of Al 2 O 3 and SiO 2 and 4H 2 O.
본 발명에 따른 세라믹 규사는, 조성물 총 100 중량부를 기준으로, 3 내지 25 중량부의 양으로 사용된다. 3 중량부 미만의 양으로 사용하면 기능성이 저하되는 문제점이 있으며, 25 중량부를 초과하면 요구되는 강도가 저하되는 문제점이 있다. Ceramic silica sand according to the present invention is used in an amount of 3 to 25 parts by weight, based on 100 parts by weight of the total composition. When used in an amount less than 3 parts by weight, there is a problem that the functionality is lowered, and when it exceeds 25 parts by weight, there is a problem that the required strength is lowered.
본 발명에서 사용되는 증점제로는 폴리메틸셀룰로스(PMC)가 있으며, 그 예로는 에틸셀룰로스(EC), 하이드로 에틸셀룰로스(HEC), 메틸셀룰로스(MC), 하이드로 폴리메틸셀룰로스(HPMC) 등이 있고, 이들은 단독으로 사용되거나 조합하여 사용될 수 있다. Thickeners used in the present invention include polymethyl cellulose (PMC), and examples thereof include ethyl cellulose (EC), hydro ethyl cellulose (HEC), methyl cellulose (MC), hydro polymethyl cellulose (HPMC), These may be used alone or in combination.
본 발명에서 사용되는 증점제의 양은, 조성물 총 100 중량부를 기준으로, 0.01 내지 0.3 중량부의 양으로 사용된다. 0.01 중량부 미만의 양으로 사용하면 증점 효과가 떨어져 부착강도가 약해지는 문제점이 있으며, 0.3 중량부를 초과하면 몰탈의 압축 강도 및 휨 강도가 저하되는 문제점이 있다. The amount of thickener used in the present invention is used in an amount of 0.01 to 0.3 parts by weight based on 100 parts by weight of the total composition. If the amount is less than 0.01 parts by weight, there is a problem that the thickening effect is reduced and the adhesion strength is weakened. If the amount is less than 0.3 parts by weight, the compressive strength and the bending strength of the mortar decrease.
본 발명에서 사용되는 혼화제는 멜라민류이며, 그 예로는 멜멘트(바스프, 독일제품), MM-2000P(이코넥스, 한국제품) 등이 있고, 이들은 단독으로 사용되거나 혼합 사용될 수 있다. The admixtures used in the present invention are melamines, and examples thereof include melment (BASF, Germany), MM-2000P (Econex, Korea), and the like, which may be used alone or in combination.
본 발명에서 사용되는 혼화제의 양은, 조성물 총 100 중량부를 기준으로, 0.05 내지 1.5 중량부의 양으로 사용된다. 0.05 중량부 미만의 양으로 사용하면 분산성이 낮아지는 문제점이 있으며, 1.5 중량부를 초과하면 유동성이 증가되어 몰탈을 스프레이(뿜칠)할 수 없는 문제점이 생긴다. The amount of admixture used in the present invention is used in an amount of 0.05 to 1.5 parts by weight based on 100 parts by weight of the total composition. When used in an amount of less than 0.05 parts by weight, there is a problem that the dispersibility is lowered, and when it exceeds 1.5 parts by weight, the fluidity is increased to cause a problem that can not spray (spray) mortar.
본 발명에 따라 얻어진 무기질계 세라믹 보수 몰탈 조성물은 비중이 2.0인 분말로서, 몰탈 100 중량%를 기준으로 할 때 물 16 내지 20 중량%의 비로 사용한다. The inorganic ceramic repair mortar composition obtained according to the present invention is a powder having a specific gravity of 2.0, and is used in a ratio of 16 to 20% by weight of water based on 100% by weight of mortar.
