In order to solve the technical problems as described above, the super hard bore 1 type repair material according to the present invention is usually 20 to 35% by weight of Portland cement, 3 to 7% by weight of fastener, ethylene vinyl acetate (EVA) or vinyl acetate / vinyl acetate It consists of 2 to 3% by weight of re-emulsified powder resin for at least one cement selected from tate (Va / VeoVa), and 60 to 70% by weight of silica sand.
또한 상기 급결제는 칼슘알루미네이트 시멘트(CAC)21~35중량%와, 칼슘설퍼알루미네이트(CSA)21~25중량%, 탄산리튬(Li2CO3)8~10중량%, 생석회(CaO)3~6중량%, 무수석고(CaSO4)20~25중량%, 수산화알루미늄(Al2(OH)3)8~13중량%로 이루어진 무기염계와 시멘트 광물계 파우더인 것이 바람직하다. In addition, the fastener 21 to 35% by weight of calcium aluminate cement (CAC), 21 to 25% by weight of calcium sulfur aluminate (CSA), 8 to 10% by weight of lithium carbonate (Li 2 CO 3 ), quicklime (CaO) 3-6% by weight of anhydrous gypsum (CaSO 4) 20 ~ 25% by weight, preferably aluminum hydroxide (Al 2 (OH) 3) 8 to the inorganic salt-based and cement mineral powder consisting of 13% by weight.

또한 상기 보통포틀랜드시멘트와 급결제를 합한 혼합물의 100중량부에 대하여, 각각 나프탈렌계 분말 유동화제 1~5중량부, 지연제 0.1~1.0중량부가 더 혼입 되는 것이 더욱 바람직하다. Further, it is more preferable that 1 to 5 parts by weight of naphthalene-based powder fluidizing agent and 0.1 to 1.0 parts by weight of retardant are added to 100 parts by weight of the mixture of the ordinary portland cement and the fastener.
이하, 본 발명의 구성 및 작용을 구체적으로 설명한다. Hereinafter, the configuration and operation of the present invention will be described in detail.
상기 급결제는 칼슘알루미네이트 시멘트(CAC)21~35중량%와, 칼슘설퍼알루미네이트(CSA)21~25중량%, 탄산리튬(Li2CO3)8~10중량%, 생석회(CaO)3~6중량%, 무수석고(CaSO4)20~25중량%, 수산화알루미늄(Al2(OH)3)8~13중량%로 이루어진 무기염계와 시멘트 광물계 파우더인데, 여기서 칼슘알루미네이트 시멘트(CAC)와 팽창성 칼슘설퍼알루미네이트(CSA)는 특수 클링커를 분쇄하여 제조한 특수 시멘트로 기본적인 특성은 기존 콘크리트에 사용되는 보통 포틀랜드 시멘트와 유사하며 응결 및 경화를 촉진시킨다. The fastener 21 to 35% by weight of calcium aluminate cement (CAC), 21 to 25% by weight of calcium sulfur aluminate (CSA), 8 to 10% by weight of lithium carbonate (Li 2 CO 3 ), quicklime (CaO) 3 Inorganic salt and cement mineral powder consisting of ~ 6% by weight, 20-25% by weight of anhydrous gypsum (CaSO 4 ), aluminum hydroxide (Al 2 (OH) 3 ) 8-13% by weight, where calcium aluminate cement (CAC) And Expandable Calcium Sulfur Aluminate (CSA) is a special cement made by grinding a special clinker. Its basic properties are similar to those of ordinary Portland cement used in existing concrete and promote condensation and hardening.
상기 탄산리튬(Li2CO3)은 CaO-Al2O3계 소성물과 CaO-Al2O3-CaSO4계 소성물의 급결성을 보완적 역할을 하지만, 그 혼합량은 CaO-Al2O3계 소성물과 CaO-Al2O3-CaSO4계 소성물 100 중량물에 대해 10~40 중량부가 바람직하며, 만일 10 중량부 미만일 경우는 Al2O3 ion의 용출의 증진이 충분히 나오지 않고, 충분한 급결성을 나타내지 않을 수 있으므로 유의해야 하며, 또 이것이 40 중량부를 넘으면 장기강도 및 내구성이 저하되는 경우가 발생할 수 있다. 더불어 생석회(CaO)는 에트링가이트의 생성량 및 생성 속도를 제어하는 중요한 역할을 하며, 그 혼합비율은 CaO-Al2O3계 소성물과 CaO-Al2O3-CaSO4계 소성물 100 중량부에 대해 5~40 중량부가 바람직하며, 만일 이것이 40 중량부를 초과하면 강도발현성이 저하되는 원인이 되며 5 중량부 미만에서는 충분한 급결성이 나타나지 않는다. The lithium carbonate (Li 2 CO 3 ) complements the quickness of CaO-Al 2 O 3 -based calcined product and CaO-Al 2 O 3 -CaSO 4 -based calcined product, but the mixed amount is CaO-Al 2 O 3 based fired product with CaO-Al 2 O 3 -CaSO 4 based plastic 10 to 40 for the heavy water 100 parts by weight preferred, and if 10 parts by weight is less than the increase of the Al 2 O 3 ion elution does not come out well, sufficient Care should be taken because it may not show quickness, and if it exceeds 40 parts by weight, long-term strength and durability may be degraded. In addition, quicklime (CaO) plays an important role in controlling the production rate and the rate of formation of ettringite, and the mixing ratio is 100 wt% of CaO-Al 2 O 3 -based calcined material and CaO-Al 2 O 3 -CaSO 4 -based fired material. 5 to 40 parts by weight per part is preferred, and if this exceeds 40 parts by weight, the strength developability is lowered, and less than 5 parts by weight does not show sufficient fastness.
또한 탄산리튬, 무수석고, 수산화알루미늄은 시멘트 페이스트, 모르타르, 콘크리트의 응결, 경화를 현저하게 촉진시켜 높은 강도 및 장기 강도 발현을 유도하기 위한 요소이다. In addition, lithium carbonate, anhydrous gypsum and aluminum hydroxide are elements for inducing high strength and long-term strength by remarkably promoting the condensation and curing of cement paste, mortar, and concrete.
이와 같이 급결제를 무기염계와 시멘트 광물계 파우더로 구성하는 것은, 상호 보완적으로서 무기염계의 경우는 비교적 경제적이고 첨가량이 적으며 시멘트 광물계의 경우는 급결력을 강화시키고, 반발을 감소시켜 용수부(勇水部)에서도 사용가능한 장점이 있기 때문이다. In this way, the composition of the inorganic filler and the cement mineral powder is complementary. In the case of the inorganic salt, the amount of the additive is relatively economical and the amount of addition is small. This is because there is an advantage that can be used in water.
또한 상기 급결제는 시멘트의 응결시간을 현저히 단축시킴으로써 분사 공사 등에 사용할 수 있어 1재형의 프리믹스형으로 제조할 경우 공기를 단축시킬 뿐만 아니라 굴삭면이나 노출면 등에 건식 배합된 콘크리트 재료와 물을 압축공기로 뿜어 붙이는 숏크리트와 같은 순간적인 응결과 경화가 요구되는 경우에 리바운드량을 감소시키고 초기강도 발현 측면에서도 효과적이다 할 수 있다. 특히 본 발명은 보통 포틀랜드시멘트의 주성분과 유사한 무기질 시멘트 광물계이므로 방식성 및 내약품성, 접착성 및 시공 후 내후성이 뛰어나다. In addition, the quickener can be used for spraying work by significantly shortening the cement setting time, so that when the production of a pre-mixed material of one type, not only shortens the air, but also dry-mixed concrete material and water, such as excavated or exposed surfaces, and compressed air If instantaneous condensation and hardening, such as shotcrete, are required, hardening can be reduced and effective in terms of initial strength development. In particular, the present invention is an inorganic cement mineral system similar to the main components of the portland cement, so the corrosion resistance and chemical resistance, adhesion and weatherability after construction is excellent.
상기 시멘트 혼화용 재유화형 분말수지는 에틸렌 초산 비닐(EVA) 또는 초산비닐/비닐바사테이트(Va/VeoVa) 중 선택된 어느 하나 이상으로 구성되는데, 겉보기 비중은 475±g/l, 입도는 max,2%>400㎛이고, 물에 재분산 시 0.3~9㎛의 입도분포를 나타낸다.The cement re-emulsifying powder resin is composed of any one or more selected from ethylene vinyl acetate (EVA) or vinyl acetate / vinyl acetate (Va / VeoVa), the apparent specific gravity is 475 ± g / l, the particle size is max, 2 %> 400㎛, and redispersion in water shows particle size distribution of 0.3 ~ 9㎛.
위와 같이 구성된 급결제와 보통포틀랜드시멘트의 치환에 의하여 결합재가 완성된다. 또한 상기 재유화형 분말수지 및 다량의 규사로 이루어지며, 이에 부가적으로 소량의 소포제 및 분말 유동화제, 지연제(주석산)가 더 혼입되어 이루어진다. 상기 소포제는 재유화형 분말수지 혼입시 생성되는 연행공기를 제어하는 요소이다. The binder is completed by the substitution of the above-mentioned fastener and the ordinary portland cement. In addition, the re-emulsified powder resin and a large amount of silica sand, in addition to the small amount of the antifoaming agent, powder fluidizing agent, retardant (tin acid) is further mixed. The antifoaming agent is an element for controlling entrained air generated when incorporating a reemulsified powder resin.
또한 유동화제는 나프탈렌계 분말 유동화제를 사용하는데, 이는 감수제 역할과 작업성을 향상시켜 시멘트 모르타르의 강도 증진 역할을 담당한다. In addition, the fluidizing agent uses a naphthalene-based powder fluidizing agent, which serves to enhance the strength of the cement mortar by improving the role and workability of the water reducing agent.
상기 규사는 골재이고, 상기 보통포틀랜드시멘트는 급결제와 치환하여 사용하는 결합재로서 재유화형 분말수지의 증량재 역할 및 골재인 상기 규사들 사이의 공극을 메우고 결합시킴으로써 보수재료의 강도증진 효과를 갖는다. 특히 상기 보통포틀랜드시멘트의 급결제와의 치환량이 전체 조성물의 10중량% 초과일 경우, 강도증진 효과 및 응결시간의 단축효과가 더 이상 증대하지 않으며, 3중량% 미만일 경우, 응결시간의 단축효과를 기대할 수 없다.The silica sand is an aggregate, and the ordinary portland cement serves as an extender of a reemulsifying powder resin as a binder to be used in place of a fastener and fills and bonds the voids between the silica sands to increase the strength of the repairing material. In particular, when the substitution amount of the ordinary Portland cement with the fastener is more than 10% by weight of the total composition, the strength-improving effect and the shortening effect of the setting time does not increase any more.

본 발명에 따르면, 재유화형 분말수지를 이용하기 때문에 초속경 보수재료가 1재형(材形)으로 구성되어 프리믹스(premix)포장이 가능하기 때문에, 기존의 현장에서 배합하여 사용하는 폴리머 디스퍼젼과 시멘트계 필러로 구성된 2재형 보수재료와는 달리 환경부하저감, 품질관리능력 및 시공성능을 향상시킬 수 있으며, 내구성이 증진된다. According to the present invention, since the re-emulsified powder resin is used, the superfast repair material is composed of one type, and premix packaging is possible, so that the polymer dispersion and cement system used in the existing field can be mixed. Unlike two-type repair materials composed of fillers, it can reduce environmental load, improve quality control and construction performance, and improve durability.
특히, 초속경성, 저온경화성, 내약품성, 접착성 및 내후성이 뛰어난 효과가 있다. In particular, there is an effect excellent in ultra-fast curing, low temperature curing, chemical resistance, adhesiveness and weather resistance.
