Description
본 발명은 고성능의 휨강도 특성을 갖는 초속경 보수성 몰탈 조성물 및 이를 이용한 시공방법에 관한 것으로서, 보다 상세하게는 레진계에 준하는 고성능의 휨강도와 몰탈의 특성에 맞는 고성능의 압축강도를 발현 할 수 있도록 하고, 속경성 및 보수성이 요구되는 시공에 적용 가능하도록 한 고성능의 휨강도 특성을 갖는 초속경 보수성 몰탈 조성물 및 이를 이용한 시공방법에 관한 것이다.
More particularly, the present invention relates to a high-speed light-hardenable mortar composition having a high-performance bending strength property and a high-performance compressive strength suitable for a high-performance bending strength similar to a resin system and mortar characteristics , A quick-setting water-repellent mortar composition having a high-performance bending strength property which is applicable to fast-setting and watertight construction, and a construction method using the same.
최근 도시화로 인해 주거, 상업, 공공시설 등이 늘어나면서 조경면적이 공개공지 등으로 전환되어 인공구조물이 증가하면서 도심의 열 축적 현상에 의한 열섬효과현상이 발생하고 있다. Recently urbanization has increased residential, commercial, and public facilities, and the landscape area has been converted to public notice, resulting in the increase of artificial structures.
이러한 현상은 습식공사의 경우 시공면 위에 저류하는 수분을 조기에 증발시켜 정상적인 수화반응에 의한 양생 및 경화과정을 방해할 수 있을 뿐만 아니라, 콘크리트의 강도에 영향을 줄 수 있기 때문에 간과해서는 안 되는 요인으로 이해하여야 한다.This phenomenon can not only prevent the curing and curing process due to normal hydration reaction by evaporating the water stored on the construction surface early in the case of wet construction but also affect the strength of the concrete, .
따라서 열용량이 적고 물을 최소한으로 사용하며, 사용된 물을 기온의 상승에 따라 증발시키지 않으면서도 정상적인 수화반응을 통해 양생 및 경화과정이 이루지고, 짧은 시간에 경화되면서도 강도가 높은 일반몰탈 및 보수용 몰탈의 개발이 요구되고 있다. Therefore, the curing and curing process is accomplished through normal hydration reaction without evaporation of the used water with evaporation of the used water with a low heat capacity and minimum use of water, and the curing in a short time, Development of mortar is required.
한편, 콘크리트나 아스팔트 등의 노면 또는 바닥 포장재에 사용하는 수지로는 에폭시계 수지, 우레탄계 수지 또는 아크릴계 수지 등이 알려져 있다. 그러나 종래 에폭시계 수지 또는 우레탄계 수지 등은 내마모성, 접착력 및 탄성이 우수하나, 콘크리트의 기공을 막아 경화되는 과정에서 발생하는 수분에 의해 박리현상이 생기는 하자가 발생하며 내화성을 기대할 수 없어 화재 발생 시 화재를 확산시킬 수 있는 문제점이 있다.On the other hand, an epoxy resin, a urethane resin, an acrylic resin, or the like is known as a resin used for a road surface or a floor covering material such as concrete or asphalt. Conventionally, epoxy resin or urethane resin is excellent in abrasion resistance, adhesive force and elasticity, but it has a defect that peeling occurs due to moisture generated in the process of curing by blocking pores of concrete, and fire resistance can not be expected. There is a problem in that it can diffuse.
또한, 건축물에는 내진기준이 적용되고 있으나, 도로 등과 같이 철근을 사용하지 않는 구조물의 경우 내진기준을 적용하기 어려운 경우 몰탈 및 콘크리트가 가지고 있는 압축강도와 휨강도의 중요성이 높아져야 할 시점이다. In addition, although the earthquake resistance standard is applied to buildings, it is a point that the importance of compressive strength and bending strength of mortar and concrete should be increased when it is difficult to apply the earthquake-resistant criteria for structures not using reinforcing bars such as roads.
이상에서 살펴본 바와 같이, 최근 들어 습식공사이면서 속경성을 갖는 고강도 몰탈로서, 콘크리트의 기공을 살리면서도 부착강도가 우수하며, 휨강도와 압축강도가 탁월하여 무근구조물에 사용할 수 있는 일반몰탈 및/또는 보수용 몰탈을 개발하는 것이 필요하다.
As mentioned above, recently, as a high-strength mortar having wet strength and quick hardness, it has excellent adhesion strength while maintaining pores of concrete, excellent bending strength and compressive strength, and can be used as general mortar and / It is necessary to develop a mortar for use.
본 발명은 상기와 같은 문제점을 해결하기 위해 창출한 것으로서, 1일 휨강도가 14N/mm2 이상이고, 압축강도가 40N/mm2 이상인 물리적 특성을 갖고, 신구의 탁월한 부착강도 및 내구성능을 향상시킬 수 있는 초속경 보수성 몰탈 조성물, 특정적으로 고성능의 초속경 보수성 몰탈 조성물 및 이를 이용한 시공방법을 제공하고자 한다.
