Description

콘크리트 긴급보수제 및 그 제조방법{The compositoin of for concrete sealer}Concrete emergency repair agent and its manufacturing method {The compositoin of concrete sealer}

본 발명은 콘크리트 포장도로의 파손을 급하게 보수하며 , 콘크리트 구조물 측구, 방음벽, 벽체 및 표면 강도 저하부의 강도증진을 목적으로 개발된 것으로서, 침투성강화, 증진을 위하여 침투 및 미세균열부의 부착 및 방수층까지 형성 할 수 있는 조성물로서, 콘크리트의 표면강도를 증대시키고 마모를 감소시킬 수 있는 콘크리트 긴급보수제 및 그 제조방법에 관한 것이다.The present invention has been developed for the purpose of rapidly repairing the breakage of concrete pavement, and to increase the strength of concrete structure side openings, soundproof walls, walls and surface strength lowering parts, and to form penetration and microcracking parts as well as waterproof layers to enhance and enhance permeability. As a possible composition, the present invention relates to a concrete emergency repair agent and a method of manufacturing the same that can increase the surface strength of concrete and reduce wear.

시멘트 콘크리트도로의 패인부분, 각종공사후 복구 및 부수 등의 방법에 대해서는 복구범위와 파손의 크기, 상태를 고려해서 기존의 도로상태대로 원상복구를 해야 한다.In the case of the concave part of cement concrete road, recovery and crushing after various works, the original road condition should be restored in consideration of the recovery range, size and condition of damage.

여기서 도로포장부의 구조는 밑으로부터 상부로 준비하면 토사 및 흙의 다짐층인 노상 및 노반층, 차단층 및 동상방지층, 보조기층 및 기층, 중간층과 표층등으로 분리 구성되어 있다. Here, the road pavement structure is composed of a roadbed and subgrade layer, a barrier layer and an in-phase prevention layer, an auxiliary base layer and a base layer, an intermediate layer, and a surface layer, which are prepared from the bottom to the top.

그 시공방법도 그 층별로 달리하고 있으며, 일반적으로 중간층 및 표층등이 가열혼합가열포설 아스팔트혼합물(이하 고온아스콘)과 도로포장용 시멘트 콘크리트등의 소재를 사용해서 포장체를 이루고 있다.The construction method is also different for each floor. In general, the intermediate layer and the surface layer are made of pavement using materials such as hot mixed heating asphalt mixture (hereinafter referred to as hot asphalt) and cement for road paving.

일반적으로 콘크리트도로 긴급보수제는 콘크리트의 파손을 방지하는 것을 목적으로 사용한다. 그리고 재료에 따라서 표면에 막을 형성하여 이러한 작용을 증진시키기도 한다. 이러한 보호 및 방수작용과 더불어 보수조성물이 강성을 확보하는 급속한 경화특성을 갖게 되는 경우 표면을 강화하는 작용을 하기도 한다. In general, the emergency repair agent for concrete roads is used to prevent the breakage of concrete. And depending on the material, this may be enhanced by forming a film on the surface. In addition to such protection and waterproofing action, the repair composition also acts to strengthen the surface when it has a rapid curing property to secure rigidity.

일반적으로 시멘트 콘크리트 포장도로, 콘크리트 구조물 측구, 방음벽, 벽체의 표면의 결함을 제거하는 긴급 보수 방법으로 결함부위를 제거하거나, 별도의 덧씌우기 층의 형성을 통해 결함부위가 직접적인 차량하중을 받지 않도록 하는 방법, 그리고 결함부위의 파손 진전을 억제하는 방법이 있을 수 있다.In general, it is an emergency repair method that removes defects on the surface of cement concrete pavement, concrete structures, soundproof walls, and walls, or removes defects or forms a separate overlay layer so that the defects do not receive direct vehicle load. There may be a method, and a method of suppressing the progress of breakage of the defective part.

이러한 긴급 보수 공법 중에 결함부위의 파손 진전을 억제하는 방법은 상대적으로 파손의 정도가 작은 경우에 유용하게 적용될 수 있는 경제적인 방법으로 판단된다. In this emergency repair method, the method of suppressing the progress of the breakage of the defective part is considered an economical method that can be usefully applied when the degree of damage is relatively small.

즉 표면에 나타난 파손이나 결함을 인정하나, 이러한 파손에 추가적인 진전이 없으면 포장면을 주행하는 차량의 주행성에 대한 영향이 작다는 판단에 적용하는 공법이라고 할 수 있다.That is, it recognizes the damage or defect that appeared on the surface, but if there is no further progress on such damage, it can be said to be a method applied to the determination that the influence on the runability of the vehicle traveling on the pavement surface is small.

그러나 종래의 콘크리트 긴급 보수제는 경화시간이 장기화되고, 시공후 화물차 등의 대량 통행과, 장기간 사용시, 재파손되는 경향이 있어, 이러한 문제점을 해결하기 위하여 많은 연구가 있어 왔다.However, the conventional concrete emergency repair agent has a long time to harden, tends to re-break when a long-term use, such as a large amount of traffic, such as a truck after construction, has been a lot of research to solve this problem.

상기와 같은 목적을 달성하기 위한 본 발명은 알루미나시멘트, 탄산나트륨, 명반석, 감수제, 규산계화합물, 포트랜드시멘트, 규사 및 폴리비닐알콜로 조성된 콘크리트 긴급 보수제 및 그 제조방법에 관한 것이다.The present invention for achieving the above object relates to a concrete emergency repair agent composed of alumina cement, sodium carbonate, alum, water reducing agent, silicic acid-based compound, portland cement, silica sand and polyvinyl alcohol, and a method of manufacturing the same.

본 발명의 포트랜드시멘트나 알루미나시멘트는 무기접착제로 사용되며 알루미나시멘트는 팽창제 보조역할을 하며, 경제적이거나, 시멘트 특성상 포트랜트시멘트는 24중량%, 알루미나시멘트는 25중량%가 적당하다.Portland cement or alumina cement of the present invention is used as an inorganic adhesive and the alumina cement serves as a swelling agent, economical, 24% by weight of the cement cement, 25% by weight of the alumina cement is suitable.

본 발명의 규사는 경화제 역할을 하도록 하며 36.9중량% 가 넘으면 너무 경화되고, 36.9중량% 미만이면 너무 연화되어 36.9중량%가 적당하다.The silica sand of the present invention serves as a curing agent and is too hard to be more than 36.9% by weight, too soft to be less than 36.9% by weight, so 36.9% by weight is appropriate.

본 발명의 규산계 화합물은 소듐실리케이트, 포타슘실리케이트,리듐실리케이 트,칼슘실리케이트에서 선택된 어느 하나의 화합물을 사용하며, 콘크리트 도로의 균열 및 파손된 곳에 깊게 침투하도록 사용하였고, 너무 많으면 규산계화합물의 특성이 강하고 비경제적이며, 너무 적으면 성능이 저하되어 5중량%가 바람직하다.    The silicic acid compound of the present invention is any one selected from sodium silicate, potassium silicate, lithium silicate, calcium silicate, and used to penetrate deeply into cracks and breaks of concrete roads. The property is strong and uneconomical, and if too small, the performance is degraded and 5% by weight is preferable.

본 발명의 명반석은 백반석이라고 하며, 육방결정계 광물로, 조각모양, 흙모양으로 백색, 투명에서 반투명 화산암에 화산성 가스의 황이 작용하거나 지하수속에 들어 있는 황산이 알루미나질 암석에 작용하여 생기며, 화학조성은 KAl3(OH)6(SO4)2 으로 팽창제 역할을 하며, Alumite of the present invention is called alumite, and it is a hexagonal mineral, which is formed by white sulfur, volcanic gas, sulfuric acid, or sulfuric acid in groundwater acting on alumina rock. The composition is KAl 3 (OH) 6 (SO 4 ) 2 It acts as a swelling agent,

총량 대비 4중량%가 넘으면 방수기능이 저하되고, 4중량%보다 적으면 증발속도와 용해도가 부족하여 시공시 문제점이 발생하고,If more than 4% by weight of the total amount of water-resistant function is lowered, if less than 4% by weight evaporation rate and solubility is insufficient, the construction problem occurs,

본 발명의 감수제로서는 나프탈렌술폰산 단독화합물을 포름알데히드에 의하여 축합한 축합물(일본특허공개소61-83659호)이나 술폰화한 멜라민의 포름알데히드 축합물 또는 리그닌술폰산 나트륨염에서 선택된 어느 하나의 화합물이 사용되고 사용량은 2중량%가 넘으면, 너무 묽어지고 2중량%가 적어지면 감수제 기능이 떨어지므로 2중량%가 바람직하다.As the water reducing agent of the present invention, any compound selected from a condensate obtained by condensation of a naphthalenesulfonic acid homogeneous compound with formaldehyde (formerly Japanese Patent Application Laid-Open No. 61-83659), or a formaldehyde condensate of sulfonated melamine or sodium lignin sulfonic acid salt If the amount used is more than 2% by weight, too thin and 2% by weight is reduced, so that the water content of the reducing agent is deteriorated, so 2% by weight is preferable.

본 발명에서 사용되는 탄산나트륨은 무수물은 백색 분말의 흡습성이 강하며, 3중량% 가 넘으면 비경제적이며, 3중량% 이하이면 탄산나트륨의 특성이 저하되므로 3중량%가 적당하다.Sodium carbonate used in the present invention, the anhydride is strong hygroscopicity of the white powder, more than 3% by weight is uneconomical, if less than 3% by weight of sodium carbonate deteriorates 3% by weight is suitable.

본 발명의 폴리비닐알콜은 방수제가 시공하는 과정에서 시공체의 표면에 부착이 잘되도록 도와주며, 낮은 온도에서 증발하여 습기를 유인 제거하고, 알콕시실란의 화학반응을 촉진시키는 역할을 하며, 비극성인 탄화수소성분으로만 구성된 용제를 부분극성화 시킴으로서, 별도의 첨가제 없이 정전기 발생을 억제하기 위하여 사용되는 것이다.The polyvinyl alcohol of the present invention helps to adhere well to the surface of the construction during the construction of the waterproofing agent, evaporates at a low temperature to attract moisture, promotes the chemical reaction of the alkoxysilane, non-polar By polarizing a solvent composed only of hydrocarbon components, it is used to suppress the generation of static electricity without any additives.

본 발명의 구성성분의 총량대비 폴리비닐알콜 사용량은 0.1중량%보다 많을 경우에는 시공체의 표면에 너무 잘 부착되는 반면, 방수층이 묽어지는 반면 증발로 인한 습기제거 효과는 크고,When the amount of polyvinyl alcohol to the total amount of the constituents of the present invention is more than 0.1% by weight, it adheres well to the surface of the construction body, whereas the waterproofing layer is diluted, while the moisture removal effect due to evaporation is large,

상기 보다 적게 사용하면, 시공체의 표면에 잘부착되지 않는 반면 방수층이 진해지는 반면 증발로 인한 습기제거 효과가 적기 때문에, 바람직한 사용량은 구성성분의 총량대비 0.1중량%를 사용하는 것이다.When the less is used, the preferred amount is 0.1% by weight relative to the total amount of the constituents because it is less adhered to the surface of the construction while the waterproofing layer is thicker and the moisture removal effect due to evaporation is less.
