Field of the Invention [0001] The present invention relates to a building material for building interior and exterior, and more particularly, to a building material for exterior and interior use in a building having a warmth, a sound insulation and a lightweight property by foam molding with a predetermined size such as a brick, a block and a panel.
일반적으로 건축구조물은, 외장용으로 창호부위를 제외한 외부 노출부분 및 내부 구획부분이 벽체로 이루어지고 있으며, 내부 또는 외부의 벽체는 콘크리트 또는 시멘트 블록이 시멘트 몰탈에 의해 상호 결합되어 형성되고, 상기 콘크리트 또는 시멘트 블록은 통상 큰 하중에 견딜 수 있는 강도가 내포된 중량 콘크리트 또는 시멘트로 이루어져 있다.Generally, the building structure is made of a wall for externally exposed portions and inner partition portions except for a window portion, and the inner or outer wall is formed by mutually coupling concrete or cement block by cement mortar, Cement blocks usually consist of heavy concrete or cement with strength that can withstand large loads.
그러나, 상기와 같이 콘크리트 또는 시멘트 블록을 시멘트 몰탈에 의해 조적하여 수직벽체를 형성하는 방법은, 시멘트 몰탈에 의해 숙련된 노동력을 필요로 할 뿐만 아니라 완공된 건물의 자체 하중이 높기 때문에 기초 공사를 초기부터 확실히 하여야 하며, 이에 따라 건축비가 많이 소요되는 문제점이 있었다.However, the method of forming the vertical wall by combining the concrete or the cement block with the cement mortar as described above requires a skilled workforce by the cement mortar, and since the self-load of the completed building is high, Therefore, there is a problem that a large amount of construction costs are required.
또한, 중량 콘크리트 블록 또느 시멘트 벽돌을 이용하여 벽체를 구성할 경우, 벽체를 구성하는 중량의 콘크리트 블록과 시멘트 몰탈에 의해 블록에 요구되는 강도가 더욱 크게 되고, 이와 같이 설치된 벽체로 이루어진 건물은 그 자체 하중이 매우 크게 되는 문제점이 발생되었다. 특히, 중량 콘트리트 블록 및 시멘트 벽돌은 단위부피당 중량이 무거워, 이를 작업현장으로의 운반이동하기 위한 운반시간 및 조적하기 위한 시공시간이 많이 소요될 뿐 아니라, 벽체를 형성시킬때 작업자가 하나 하나의 블록을 들어서 쌓아가야 하므로, 작업자에게 매우 큰 힘을 요구하게 되어 피로감을 가중시키는 문제점이 있었다.In addition, when a heavy concrete block or a cement brick is used to construct a wall, the strength required for the block is increased by the concrete block and the cement mortar, which constitute the wall, and the thus- A problem that the load becomes very large has occurred. Particularly, the heavy concrete block and the cement brick have a heavy weight per unit volume, and it takes a lot of time for transporting and transporting them to a work site, and a construction time is required. Also, when the wall is formed, There is a problem that the worker is required to apply a very great force to the worker to increase fatigue.

본 발명은 건물의 내외장에 설치되는 건축자재에 있어서; 상기 건축자재는 시멘트 100 중량부에 대하여, 플라이애쉬 28∼40 중량부, 하이드록시 프로필 메틸 셀룰로즈 0.19∼0.50 중량부, 재분산성 라텍스 파우더 0.15∼0.20 중량부, 경량단열재 1∼10 중량부, 감수제 0.55∼0.88 중량부, 기포제 0.1∼0.3 중량부, 물 75∼88 중량부를 포함한다.The present invention relates to a building material installed in an interior and exterior of a building, Wherein the building material comprises 28 to 40 parts by weight of fly ash, 0.19 to 0.50 parts by weight of hydroxypropylmethylcellulose, 0.15 to 0.20 parts by weight of redispersible latex powder, 1 to 10 parts by weight of lightweight insulation, 0.55 of water reducing agent To 0.88 parts by weight, a foaming agent 0.1 to 0.3 parts by weight, and water 75 to 88 parts by weight.
상기 건축자재(10)는, 블록, 보드, 벽돌 등등 건축구조물의 내/외장 벽체, 바닥 및 슬래브에 설치될 수 있는 다양한 형태의 건축자재를 모두 포함한다. The
상기 시멘트는 보통포틀랜드 시멘트 또는 규산염 시멘트가 사용된다. The cement is usually Portland cement or silicate cement.
상기 플라이애쉬는 고강도 발현을 위한 SiO2의 소스로 사용되어지는 것으로, 시멘트와 상호작용하여 강도를 증진시킨다. 즉, 상기 플라이애쉬는 보통 수화반응이 낮아 알카리 촉진이 필요한데 본 발명에서는 시멘트가 플라이애쉬의 알카리 촉진재로 사용되어 포졸란 반응을 이끌어낸다.The fly ash is used as a source of SiO 2 for high strength development and interacts with cement to enhance strength. That is, the fly ash usually has a low hydration reaction and needs to promote alkali. In the present invention, cement is used as an alkali promoter of fly ash, leading to a pozzolanic reaction.
상기 플라이애쉬는 28중량부 미만으로 첨가될 경우, 장기강도증진효율이 없으며, 40 중량부를 초과하여 첨가될 경우, 과도한 치밀화가 이루어져 기포에 좋지 못한 영향을 줄 뿐 아니라, 경량성 및 단열성을 저하시킨다.When the fly ash is added in an amount less than 28 parts by weight, there is no long-term strength enhancement efficiency. When the fly ash is added in an amount exceeding 40 parts by weight, the fly ash is excessively densified to adversely affect bubbles, .
상기 하이드록시프로필 메틸 셀룰로오스(HPMC:Hydroxpropyl Methyl Cellulose)는 낮은 온도에서도 우수한 접착력이 발현되도록 하는 기능 및, 재분산성 라텍스 파우더의 분산성을 향상시키는 기능을 동시에 구비한다. Hydroxypropyl methyl cellulose (HPMC) has both a function of exhibiting excellent adhesion even at a low temperature and a function of improving the dispersibility of the redispersible latex powder.
즉, 상기 하이드록시프로필 메틸 셀룰로오스(HPMC:Hydroxpropyl Methyl Cellulose)는 시멘트 및 플라이애쉬로 이루어지는 무기입자내에서 고르게 분포하게 재분산성 라텍스 파우더가 고르게 분포되도록 하는 기능을 구비한다.That is, HPMC (Hydroxpropyl Methyl Cellulose) has a function of evenly distributing the redispersible latex powder evenly distributed in the inorganic particles composed of cement and fly ash.
또한, 상기 하이드록시프로필 메틸 셀룰로오스(HPMC:Hydroxpropyl Methyl Cellulose)는 재분산성 라텍스 파우더의 안정성을 향상시키는 기능도 구비한다.In addition, the hydroxypropyl methyl cellulose (HPMC) has a function of improving the stability of the redispersible latex powder.
또한, 상기 하이드록시프로필 메틸 셀룰로오스(HPMC:Hydroxpropyl Methyl Cellulose)는 시공성 개선 및 속용성을 가지며, 시멘트 및 플라이애쉬가 물과 혼합되었을 때 점도를 증진시킬 뿐 아니라, 수분을 지속적으로 공급하여 시멘트의 수화반응을 장기적으로 지속시키는 기능을 구비한다. The hydroxpropyl methyl cellulose (HPMC) has improved workability and quick availability. It not only improves viscosity when cement and fly ash are mixed with water, but also continuously supplies water to hydrate the cement And has a function of continuing the reaction for a long period of time.
상기 재분산성 라텍스 파우더는 시멘트에 첨가되어 라텍스의 성질부여 즉, 접합강도, 유연성, 치밀성, 그리고 내수성 을 향상시키기 위하여 첨가되는 것으로, 물과 함께 혼합 후 자연적 또는 인위적인 물의 증발 과정을 통하여 서로간의 결합력을 향상시킨다. 즉, 상기 재분산성 라텍스 파우더는 시멘트의 수화물인 수산화칼슘(Ca(OH)2)의 시멘트의 칼슘이온(Ca+) 및 고상 수산화칼슘(Ca(OH)2)입자의 칼슘(Ca)과 반응하여 강한 접착력을 나타낸다.The redispersible latex powder is added to the cement in order to improve the properties of the latex, that is, to improve the bonding strength, flexibility, denseness and water resistance. The latex powder is mixed with water, and then the natural or artificial water is evaporated, . In other words, the redispersible latex powders are of a hydrate of the cement of calcium hydroxide (Ca (OH) 2), calcium ions of the cement of the (Ca +) and solid calcium hydroxide (Ca (OH) 2) calcium particles (Ca) reacts with strong adhesion .
상기 재분산성 라텍스 파우더는 라텍스 중합체 60∼80중량%과 함께, 수용성 폴리비닐알콜 15∼30중량%, 폴리아크릴산 1∼10중량%를 분무건조한 것이 사용될 수 있다. The redispersible latex powder may be prepared by spray-drying 15 to 30% by weight of a water-soluble polyvinyl alcohol and 1 to 10% by weight of a polyacrylic acid together with 60 to 80% by weight of a latex polymer.
상기 라텍스 중합체는, 스티렌 부타디엔, 비닐 아세테이트 에틸렌, 스티렌 아크릴, 비닐 아크릴, 에틸렌 비닐베르사테이트 및 그의 조합으로 이루어진 군으로부터 선택된 것이 사용되며, 재분산가능한 분말이 입자 형태로 존재하고, 상기 입자의 평균 직경이 약 500 ㎛ 미만인 것이 사용된다. Wherein said latex polymer is selected from the group consisting of styrene butadiene, vinyl acetate ethylene, styrene acrylic, vinyl acrylic, ethylene vinyl versatate, and combinations thereof, wherein the redispersible powder is present in particulate form, Those having a diameter of less than about 500 탆 are used.
상기 폴리비닐알콜은 라텍스 중합체의 재분산성을 향상시키고, 기포제에 의해 형성된 기포의 안정화를 꾀하기 위하여 첨가되며, 상기 폴리아크릴산은 라텍스 중합체의 결합력을 더욱 향상시키기 위하여 첨가된다. 상기 폴리아크릴산은 중합체 골격 내에 주요 부분(예를 들어 50% 이상), 바람직하게는 90% 이상의 중합된 아크릴산 단위를 갖는 중합체를 의미하며, 상기 폴리비닐알콜 및 폴리아크릴산은 시중에 판매되고 있는 공지의 것이 사용될 수 있다. The polyvinyl alcohol is added to improve the redispersibility of the latex polymer and to stabilize the bubble formed by the foaming agent, and the polyacrylic acid is added to further improve the binding force of the latex polymer. The polyacrylic acid means a polymer having a main part (for example, 50% or more), preferably 90% or more, of polymerized acrylic acid units in the polymer backbone, and the polyvinyl alcohol and polyacrylic acid are commercially available May be used.
상기와 같이 이루어진 재분산성 라텍스 파우더는 시멘트와 혼용 사용시 시멘트 입자와의 가교역할을 하여 휨인성 향상, 방수특성 향상, 치밀성 유지, 내구성 증진 및 온도편차에 따른 재료의 안정성을 부여하게 된다. The redispersible latex powder as described above acts as a crosslinking agent to cement particles when used in combination with cement, thereby improving flexural toughness, improving waterproof property, maintaining compactness, improving durability, and providing stability of material due to temperature variation.
상기 경량단열재는 건축패널의 단열성 및 경량성을 부여하기 위한 것으로, EPS 알갱이 또는 버텀애쉬가 첨가된다. The lightweight insulating material is for imparting heat insulation and light weight to the building panel, and EPS grains or bottom ashes are added.
상기 버텀애시는 화력발전소에서 나오는 산업부산물로 경량 다공성을 구비하고 있어, 우수한 단열성 및 흡음성을 구비한다. 또한, 상기 버텀애시는 잠재 수경성을 가지고 있어 장기 강도 발현 및 내구성을 개선시키는 역할을 한다. 상기 버텀애시는 입경 약 2∼15㎜ 의 것이 첨가된다. The bottom ash is an industrial by-product from a thermal power plant and has lightweight porosity, and has excellent heat insulation and sound absorption. In addition, the bottom ash has latent hydraulic properties, thereby improving long-term strength development and durability. The bottom ash having a particle diameter of about 2 to 15 mm is added.
상기 EPS(Expanded PolyStyrene) 알갱이는 경량성, 단열성 및 흡음성을 부여하기 위하여 첨가되는 것으로 직경 0.1∼10㎜ 의 것이 첨가된다.The EPS (Expanded PolyStyrene) grains are added in order to impart lightness, heat insulation and sound-absorbing property, and those having a diameter of 0.1 to 10 mm are added.
상기 경량단열재는 에폭시실란으로 코팅된 것이 사용될 수 있으며, 이와 같이 에폭시 실란이 표면에 코팅된 경량단열재는 시멘트내에서 우수한 분산성 및, 결합력을 구비하게 된다. The lightweight insulator may be coated with an epoxy silane. The lightweight insulator coated on the surface of the epoxy silane may have excellent dispersibility and bonding power in the cement.
즉, 상기 에폭시 실란은 친수기와, 무기재료 특히 실리카(Si)와 결합이 용이한 소수기를 동시에 구비하고 있어, 시멘트내의 실리카와 반응하여 경량단열재의 고착력을 증대시키는 기능을 구비한다. That is, the epoxy silane has a hydrophilic group and a hydrophobic group that is easily combined with inorganic material, particularly, silica (Si), and has a function of reacting with silica in the cement to increase the fixing force of the lightweight heat insulator.
특히, 상기 에폭시계 실란은 실록산 구조의 수소기를 구비하고 있어, 시멘트 성분이 수화되면서 시멘트 겔체가 형성되어 실록산 부분과 수소결합이 진행되는 화학결합이 유도되게 되며, 이와 같은 수소결합에 의해 시멘트와의 결합력이 더욱 증대되어 균열저항성이 크게 향상되는 효과를 부여하게 된다. Particularly, since the epoxy silane has a siloxane structure, the cement component is hydrated and a cement gel is formed to induce a chemical bond in which the siloxane moiety and the hydrogen bond progress, and by the hydrogen bonding, The bonding force is further increased and the effect of greatly improving the crack resistance is given.
또한, 에폭시실란이 코팅된 EPS(Expanded PolyStyrene) 알갱이는 난연성을 구비하게 되어 시멘트의 수화반응시 발생되는 열로부터 EPS(Expanded PolyStyrene)의 손상이 방지되어 우수한 단열성 및 경량성이 유지되게 된다. In addition, EPS (Expanded PolyStyrene) grains coated with epoxy silane are provided with flame retardancy, so that EPS (Expanded PolyStyrene) is prevented from damage due to heat generated in the hydration reaction of cement, so that excellent heat insulation and light weight can be maintained.
이와 같은 경량충전재는 경량충전재를 혼합기에 넣고, 에폭시계 실란을 투입하여 교반하는 방법으로 형성할 수 있다.Such a light-weight filler can be formed by adding a light-weight filler into a mixer, adding epoxy silane, and stirring.
또한, 상기 경량단열재는 건축자재에 있어서, 1∼10 중량부를 구비하되, 단위용적중량(㎏/㎥) 0.7∼0.9 을 구비하도록 첨가된다. The lightweight insulating material is added to the building material in an amount of 1 to 10 parts by weight, and a unit volume weight (kg / m 3) of 0.7 to 0.9.
상기 감수제는 물-시멘트비를 감소시켜 강도 및 내구성을 개선하고, 시멘트 입자를 분사시켜 유동성을 확보하기 위하여 첨가된다. 상기 감수제는 폴리카본산계, 멜라민계 또는 나프탈렌계 유동화제를 사용할 수 있다. 멜라민계 또는 나프탈렌계 감수제는 폴리카본산계 감수제에 비하여 강도 및 내구성의 개선 효과가 미약하고, 물-시멘트비의 저감 효과가 크지 않으며, 재분산성 라텍스 파우더와 혼합되는 경우 거품현상이 발생하여 혼화성이 나쁘다는 단점이 있으므로, 상기 감수제는 폴리카본산계 감수제를 사용하는 것이 바람직하다. The water reducing agent is added to improve the strength and durability by decreasing the water-cement ratio, and injecting cement particles to secure fluidity. The water reducing agent may be a polycarbonate-based, melamine-based or naphthalene-based fluidizing agent. The melamine- or naphthalene-based water reducing agent is less effective in improving the strength and durability than the polycarboxylic acid-based water reducing agent, has a small effect of reducing the water-cement ratio, and has poor mixing property when mixed with the redispersible latex powder It is preferable to use a polycarboxylic acid-based water reducing agent as the water reducing agent.
상기 기포제는 E.V.A(Ethyrene Vinyl Acetate), 주석나트륨, 알루미늄 기포제, 혼합기포제 중 하나가 첨가될 수 있으며, 바람직하게는 시멘트 입자간의 접착력을 강화시키는 역할을 하는 E.V.A(Ethyrene Vinyl Acetate) 또는, 기포안정성을 구비하는 혼합기포제가 첨가되고, 더룩 바람직하게는 혼합기포제가 첨가된다. The foaming agent may be one selected from the group consisting of EVA (Ethylene Vinyl Acetate), sodium tin, aluminum foaming agent and mixed foaming agent. EVA (Ethylene Vinyl Acetate), which enhances the adhesion between the cement particles, The mixed bubble forming agent is added, and the mixed bubble forming agent is preferably added.
상기 혼합기포제는 가수분해 단백질 60∼80wt%, 2-메틸-2,4-펜탄디올(2-Methyl-2,4-pentanediol) 5∼15wt%, 폴리비닐알콜 1∼10wt%, 부틸렌글라이콜(Butylene Glycol) 1∼5wt%, 물 10∼30wt%를 포함한다.Wherein the mixed foam stabilizer is selected from the group consisting of 60 to 80 wt% of hydrolyzed protein, 5 to 15 wt% of 2-methyl-2,4-pentanediol, 1 to 10 wt% of polyvinyl alcohol, (Butylene Glycol) 1 to 5 wt%, and
상기 가수분해 단백질은 동물의 가죽, 뿔, 물고기 비닐, 뼈, 깃털 등등의 각질함유물질을 수산화나트륨으로 가수분해하여 형성된 폴리펩티드 및 아미노산으로 이루어 것으로 pH 7∼8을 구비한다.The hydrolyzed protein is composed of a polypeptide and an amino acid formed by hydrolyzing the keratin-containing material such as animal skin, horn, fish vinyl, bone, feather, etc. with sodium hydroxide and has a pH of 7 to 8.
즉, 상기 가수분해 단백질은 각질함유물질 100중량부를 세척하여 가수분해조에 넣고, 물 800∼1,500중량부, 수산화나트륨 8∼15중량부 및 환원제 0.5∼1.5중량부를 첨가한 후, 90∼100℃로 유지하면서 교반 가수분해하여 폴리펩티드 및 아미노산으로 이루어진 것을 생성할 수 있다.That is, the hydrolyzed protein is prepared by washing 100 parts by weight of the keratin-containing material into a hydrolysis vessel, adding 800 to 1,500 parts by weight of water, 8 to 15 parts by weight of sodium hydroxide and 0.5 to 1.5 parts by weight of a reducing agent, While stirring and hydrolyzing to produce the polypeptide and the amino acid.
상기 2-메틸-2,4-펜탄디올(2-Methyl-2,4-pentanediol)은 낮은 온도에서의 작업성을 개선시키고, 기포 촉진기능을 구비한다. 상기 2-메틸-2,4-펜탄디올(2-Methyl-2,4-pentanediol)은 6wt% 미만으로 첨가될 경우, 기포촉진 기능 및 응고점 강하기능을 기대하기 어려우며, 15wt%를 초과할 경우 다른 성분들의 함량에 영향을 주므로, 적정범위내에서 첨가되어야 한다.The 2-methyl-2,4-pentanediol improves the workability at a low temperature and has a bubble promoting function. When 2-methyl-2,4-pentanediol is added in an amount of less than 6 wt%, it is difficult to expect the foam promoting function and the solidifying point lowering function. When the content is more than 15 wt% It affects the content of the components, so it should be added within an appropriate range.
상기 폴리비닐알콜은 보습성, 분산성, pH 안정성 및, 장기간 저장안정성을 향상시키는 기능을 구비한다. 특히 폴리비닐알콜은 기포유지성을 향상시킨다. The polyvinyl alcohol has a function of improving moisture retention, dispersibility, pH stability and long-term storage stability. In particular, polyvinyl alcohol improves bubble retention.
상기 부틸렌글라이콜(Butylene Glycol)은 용해성이 양호하고, 우수한 분산성을 구비하고 있어, 시멘트, 플라이애쉬 및 재분산 라텍스 파우더의 분산성을 향상시킬 뿐 아니라, 성형발포된 기포안정성을 유지시키는 기능을 구비한다. The butylene glycols have good solubility and excellent dispersibility, so that not only the dispersibility of cement, fly ash and redispersed latex powder can be improved but also the function of maintaining foamed foam stability Respectively.
이와 같은 혼합기포제는 플라이애쉬가 함유된 시멘트에 있어서도 다른 기포제와 달리 플라이애쉬와 화학반응을 일으키지 않고 폴리비닐알콜과 부틸렌글라이콜에 의해 폐쇄된 구조의 기포를 안정적으로 형성 유지할 뿐 아니라, 약 5℃ 이하의 낮은 온도에서도 안정적으로 기포가 형성되도록 하는 특성을 구비한다. Unlike other foaming agents, these mixed foam agents can not only form stable bubbles in a closed structure by polyvinyl alcohol and butylene glycol without causing chemical reaction with fly ash in cement containing fly ash, Lt; RTI ID = 0.0 > C < / RTI > or less.
또한, 본 발명은 재분산성 라텍스 파우더내 유화성분의 활성을 줄이고, 분산성 및 건조수축을 감소시키기 위하여 700∼1,000℃로 저온소성된 산화마그네슘(MgO) 0.1∼2 중량부 및, 황산마그네슘 0.1∼2 중량부가 더 첨가될 수 있다. The present invention also relates to a process for producing a redispersible latex powder, comprising the steps of: 0.1-2 parts by weight of magnesium oxide (MgO) baked at a low temperature of 700-1,000 DEG C to reduce the activity of the emulsified component in the redispersible latex powder and reduce dispersibility and drying shrinkage; 2 parts by weight may be further added.
상기 저온소성된 산화마그네슘(MgO)은 플라이애시의 활성도 지수를 향상시킬 뿐 아니라, 일반적인 산화마그네슘(MgO)에 비해, 수화작용이 매우 느린 특성을 구비하게 되어, 시멘트의 건조수축을 감소시키고, 장기팽창성을 향상시키게 된다. The low temperature calcined magnesium oxide (MgO) not only improves the activity index of fly ash but also has a property of extremely slow hydration compared with general magnesium oxide (MgO), thereby reducing drying shrinkage of cement, Thereby improving the expandability.
또한, 상기 황산마그네슘은 반응성을 촉진시켜 강도를 향상시키는 기능 및, 재분산성 라텍스 파우더의 분산성을 향상시키는 기능을 구비한다. The magnesium sulfate has a function of improving the strength by promoting the reactivity and a function of improving the dispersibility of the redispersible latex powder.
또한, 본 발명은 중공섬유사 0.1∼3 중량부를 더 포함할 수 있다. 상기 중공섬유사는 균열과 휨 및 인장강도를 개선시키고 수축균열을 억제하기 위하여 첨가되며, 시멘트 수화시 수분을 제공하는 역할을 하여 다른 합섬섬유와는 달리 시멘트와의 결합력을 높여주고, 이러한 결과로 인하여 그라우트의 수축균열 억제 효과를 부여하게 된다. 이러한 중공섬유사는 수분 4∼5중량%를 함유한 Ｃ형단면 구조의 중공섬유사가 바람직하다. The present invention may further comprise 0.1 to 3 parts by weight of hollow fiber yarn. The hollow fiber yarn is added in order to improve cracks, warpage and tensile strength and to suppress shrinkage cracking and to provide moisture in the hydration of cement, thereby increasing bonding force with cement, unlike other synthetic fibers. The shrinkage crack suppression effect of the grout is given. Such a hollow fiber yarn is preferably a hollow fiber yarn having a C-shaped cross-sectional structure containing 4 to 5% by weight of water.
또한, 상기 중공섬유사는 그 재질이 특별히 한정되는 것은 아니나, 바람직하게는 폴리에틸렌테레프탈레이트 중공섬유사 또는 나일론 중공섬유사가 사용되며, 더욱 바람직하게는 나일론 중공섬유사가 사용된다. 이와 같은 중공섬유사는 공지의 것이 사용되므로, 이에 대한 상세한 설명은 생략한다. The material of the hollow fiber yarn is not particularly limited, but polyethylene terephthalate hollow fiber yarn or nylon hollow fiber yarn is preferably used, and more preferably nylon hollow fiber yarn is used. Since hollow fibers such as those known in the art are used, a detailed description thereof will be omitted.
또한, 상기 중공섬유사는 에폭시실란으로 코팅된 것이 사용될 수 있으며, 이와 같이 코팅된 중공섬유사는 에폭시계 실란이 시멘트내의 실리카와 반응하여 중공섬유사의 고착력이 증대되고, 시멘트와의 결합력이 더욱 증대되어 균열저항성이 크게 향상되게 된다. 상기 중공섬유사의 코팅은 에폭시실란의 분무건조에 의해 코팅된다. In addition, the hollow fiber yarn coated with the epoxy silane can be used, and the coated hollow fiber yarn is improved in adhesion force of the hollow fiber yarn due to the reaction of the epoxy silane with silica in the cement, and the binding force with the cement is further increased The crack resistance is greatly improved. The coating of the hollow fiber yarn is coated by spray drying of the epoxy silane.
또한, 본 발명은 탄산나트륨(Na2CO3) 0.1∼1 중량부를 더 포함한다. 상기 탄산나트륨은 수화반응을 촉진시켜 조기강도를 증진시키고, 시멘트 수화작용이 진행되면서 생성되는 시멘트 수화물과 재수화반응을 하면서 탄산염(Calcite)을 형성함으로써, 균열발생을 방지하고 장기 강도를 증진시킨다. 상기 탄산나트륨은 0.1 중량부 미만으로 첨가될 경우, 강도증진효과를 기대하기 어려우며, 1중량부를 초과하여 첨가될 경우, 과도한 탄산염(Calcite) 생성으로 인하여 오히려 독립기포가 파괴되는 현상이 발생된다.Further, the present invention further comprises 0.1 to 1 part by weight of sodium carbonate (Na2CO3). The sodium carbonate enhances the early strength by promoting the hydration reaction and forms the carbonate (Calcite) while reacting with the cement hydrate generated as the hydration of the cement progresses, thereby improving cracking and enhancing the long-term strength. When sodium carbonate is added in an amount of less than 0.1 part by weight, it is difficult to expect the effect of improving the strength. When more than 1 part by weight of sodium carbonate is added in the sodium carbonate, the formation of excessive calcium carbonate results in the breakage of the closed cell.
