Description

친환경 단면보수용 모르타르 조성물 및 이를 이용한 단면보수공법{Eco-friendly Mortar Composition for Repair Section and Repairing Methods of Repair Section Using Thereof}Eco-friendly Mortar Composition for Repair Section and Repairing Methods of Repair Section Using Thereof

본 발명은 친환경 단면보수용 모르타르 조성물 및 이를 이용한 단면보수공법에 관한 것으로서, 보다 상세하게는 건축물의 보수, 보강, 절개면, 사면정리, 교량, 도로개량, 터널, 댐 등 각종 토목 건축공사를 포함하는 모든 건축공사에서 적용 가능한 친환경 단면보수용 모르타르 조성물 및 이를 이용한 단면보수공법에 관한 것이다.The present invention relates to an eco-friendly cross-section repair mortar composition and a cross-section repair method using the same, and more particularly, it includes various civil construction works such as repair, reinforcement, cut surface, slope preparation, bridges, road improvement, tunnels, dams, etc. It relates to an eco-friendly sectional repair mortar composition applicable to all construction projects and to a sectional repair method using the same.

일반적으로 교량의 바닥판, 도로의 노면 및 건물의 외벽과 같이 부식이나 침식이 많이 일어나는 부위를 보수 및/또는 보강하기 위한 보수공사에는 조강 포틀랜드 시멘트가 사용되고 있다.In general, crude steel Portland cement is used for repair work for repairing and/or reinforcing areas where corrosion or erosion occurs a lot, such as a bridge deck, a road surface, and an exterior wall of a building.

조강 포틀랜드 시멘트는 일반 시멘트에 비하여 시공성이 우수한 장점이 있으나, 투수성이 높아 염화물이나 수분의 침투가 발생하여 콘크리트가 부식되는 문제가 있다.Crude Portland cement has the advantage of superior workability compared to general cement, but has a problem of corrosion of concrete due to infiltration of chloride or moisture due to its high water permeability.

특히, 조강 포틀랜드 시멘트는 그 특성상 콘크리트가 경화되는 양생시간이 오래 소요되기 때문에 작업의 특성상 짧은 시간 내에 마무리하여야 하는 긴급 보수공사에 사용하기 곤란한 점이 있다.In particular, it is difficult to use crude steel Portland cement for emergency repair work that needs to be completed within a short time due to the nature of the concrete, which takes a long time to harden.

최근 긴급 보수공사에 사용되는 조강 포틀랜드 시멘트의 단점을 보완하기 위해 콘크리트에 폴리머 에멀젼을 첨가한 폴리머 시멘트 콘크리트의 사용이 점차 증가하고 있다.Recently, the use of polymer cement concrete with a polymer emulsion added to concrete is gradually increasing in order to compensate for the shortcomings of crude steel portland cement used in emergency repair work.

그러나 기존 폴리머 시멘트 콘크리트는 고가의 폴리머 디스퍼젼을 사용함으로써 공사비의 상승 원인을 제공한다.However, the existing polymer cement concrete uses expensive polymer dispersion, which increases the construction cost.

또한, 초속경 폴리머 시멘트 콘크리트는 그 재료 자체의 특성으로 인해 초기 수분 증발이 신속이 진행되어 초기 플라스틱 균열이 발생할 가능성이 있고, 건조 수축 및 수화열이 높아 균열발생이 용이하다.In addition, super-velocity polymer cement concrete has a possibility of early plastic cracking due to rapid initial moisture evaporation due to the characteristics of the material itself, and cracking is easy due to high drying shrinkage and heat of hydration.

이러한 문제점을 극복하기 위하여, 대한민국특허 제10-1512962호에는 시멘트 100중량부를 기준으로, 시멘트 결합재 7 내지 25중량부; 잔골재 35 내지 1,000중량부; 굵은골재 25 내지 1,000중량부; 감수제 0.05 내지 3중량부; 애쉬 10 내지 30중량부; 칼슘설포알루미네이트 3 내지 15중량부; 메틸메타아크릴레이트 3 내지 15중량부; 고기능 파우더 5 내지 10중량부; 보습제 5 내지 15중량부; 보습보조제 1 내지 5중량부; 광물 5 내지 10중량부; 실리카퓸 3 내지 8중량부; 및 슬래그 5 내지 20중량부를 포함하는 모르타르 조성물이 개시되어 있다.In order to overcome this problem, Korean Patent No. 10-1512962 discloses, based on 100 parts by weight of cement, 7 to 25 parts by weight of a cement binder; 35 to 1,000 parts by weight of fine aggregate; 25 to 1,000 parts by weight of coarse aggregate; 0.05 to 3 parts by weight of a water reducing agent; Ash 10 to 30 parts by weight; 3 to 15 parts by weight of calcium sulfoaluminate; 3 to 15 parts by weight of methyl methacrylate; 5 to 10 parts by weight of high-performance powder; 5 to 15 parts by weight of a moisturizer; 1 to 5 parts by weight of a moisturizing aid; 5 to 10 parts by weight of minerals; 3 to 8 parts by weight of silica fume; and 5 to 20 parts by weight of slag is disclosed.

또한, 신속한 경화를 위해 급결제를 사용하여 콘크리트를 경화시키는 방법을 사용할 수 있다.In addition, for rapid hardening, a method of hardening concrete using a quick-setting agent may be used.

한편, 현재 국내에서 일반적으로 사용되는 급결제로는 소듐실리케이트 및/또는 포타슘실리케이트를 주성분으로 하는 무기염계 급결제가 있고, 하소한 명반석으로 수산화칼슘과 반응하여 칼슘알루미네이트 수화물, 에트링가이트 등을 생성시켜 시멘트를 급결시키는 급경성 광물을 포함하는 급결제가 있으며, 칼슘알루미네이트 및/또는 칼슘설포알루미네이트계를 포함하는 시멘트계 급결제가 있다.On the other hand, as a quick-setting agent generally used in Korea, there is an inorganic salt-based quick-setting agent containing sodium silicate and/or potassium silicate as a main component, and it reacts with calcium hydroxide with calcined alum to produce calcium aluminate hydrate, ettringite, etc. There is a quick-setting admixture containing a sharp-hardening mineral for rapid setting of cement, and there is a cement-based quick-setting admixture containing calcium aluminate and/or calcium sulfoaluminate.

여기서, 상기 시멘트계 급결제는 전술한 무기염계 및 급경성 광물을 포함하는 급결제 보다 장기 강도가 우수하다. Here, the cement-based quick-setting admixture has superior long-term strength than the quick-setting admixture comprising the above-mentioned inorganic salt-based and acute hard mineral.

하지만, 상기 시멘트계 급결제는 알칼리성을 띄므로 이를 다량 사용하면 폐쇄공간 등의 특정장소에서 작업하기 곤란하고, 주변토양을 오염시킬 가능성이 있다.However, since the cement-based quick-setting admixture is alkaline, it is difficult to work in a specific place such as a closed space when a large amount is used, and there is a possibility of contaminating the surrounding soil.

본 발명은 상기와 같은 문제점을 해결하기 위해 창출한 것으로서, 작업환경을 개선하고, 환경오염을 감소시키면서도 종래 시멘트 조성물과 대등하거나 그 이상의 강도를 갖는 단면보수용 모르타르 조성물 및 이를 이용한 단면보수공법을 제공하고자 한다.The present invention was created to solve the above problems, and provides a mortar composition for cross-section repair and a cross-section repair method using the same, which improves the working environment and reduces environmental pollution while having a strength equal to or higher than that of a conventional cement composition want to

본 발명에 따른 칼슘설포알루미네이트(Calcium Sulfo Aluminate)는 수축보상, 고강도, 예를 들면 높은 압축강도와 휨강도 및 속경성 등을 부여하기 위한 것으로서, 이러한 목적을 갖는 칼슘설포알루미네이트라면 어떠한 것을 사용하여도 무방하며, 그 사용량은 시멘트 100중량부 기준으로 5 내지 30중량부인 것을 추천한다.Calcium sulfoaluminate according to the present invention is intended to provide shrinkage compensation, high strength, for example, high compressive strength, flexural strength, and rapid hardening, and any calcium sulfoaluminate for this purpose can be used. It is also recommended that the amount used is 5 to 30 parts by weight based on 100 parts by weight of cement.

여기서, 상기 칼슘설포알루미네이트의 사용량이 5중량부 미만이면 경화속도가 감소하고 30중량부 이상인 경우 체적이 팽창되는 문제점이 발생할 수 있다.Here, when the amount of the calcium sulfoaluminate used is less than 5 parts by weight, the curing rate is reduced, and when it is 30 parts by weight or more, a problem of volume expansion may occur.

한편, 상기 칼슘설포알루미네이트는 물과 접촉할 경우 순식간에 반응하여 에트린가이트(Ettringite) 수화물을 생성함으로써, 모르타르 조성물의 압축강도를 수분 내지 수 시간 안에 얻을 수 있도록 한다.On the other hand, the calcium sulfoaluminate reacts instantaneously when in contact with water to generate Ettringite hydrate, so that the compressive strength of the mortar composition can be obtained within minutes to hours.

Production is low and the intended purpose cannot be achieved.
