본 발명은 방수성이 뛰어난 콘크리트용 방수제의 제조방법에 관한 것으로, 특히 본 발명은 천연 제올라이트(Zeolite)를 함유하는 시멘트 혼합재료를 온풍기로 건조시키면서 분쇄기(Pot Mill)에 의해 충분히 혼합 분쇄시켜서 된 방수성이 우수한 콘크리트용 방수제의 제조방법에 관한 것이다.The present invention relates to a method for producing a waterproof waterproofing agent for concrete having excellent waterproofing, and in particular, the present invention relates to a waterproofing property obtained by sufficiently mixing and pulverizing a cement mixed material containing natural zeolite by a pot mill while drying with a hot air heater. It relates to a method for producing an excellent waterproofing agent for concrete.
콘크리트는 원래 불투수성이지만, 때때로 약간의 투수가 문제가 되거나, 균열로 인하여 누수되는 경우가 발생하게 된다. 뿐만 아니라, 콘크리트 블럭과 같은 구조물은 투수되기 쉬우므로 불투수성으로 바꿀 필요가 있다. 이때 콘크리트에 방수성을 부여하거나 균열 및 누수를 방지할 목적으로 방수제를 사용한다, 방수제는 무기질계 또는 유기질계등 그 종류가 다양하지만, 화학적 조성에 의하여 분류하면 염화칼슘계, 규산소다계, 지방산계, 파라핀계, 고분자 에멀젼계, 감수제등으로 구분할 수 있고, 그 중 대표적인 것은 파라핀계 및 폴리머인 수성디스퍼션 규산질의 미분말을 들 수 있다, 전자는 세멘트에 물을 흡수시키거나 건조시켜 콘크리트 속에서 굳어 발수층과 불투수층을 만들고, 후자는 소위 포졸란 반응 즉 콘크리트 속의 수용성 수산화칼슘과 규산 및 물이 반응하여 불용성 규산 칼슘수화물을 만들어 조직을 치밀하게 하기 때문이다.Concrete is originally impermeable, but sometimes a small amount of permeability becomes a problem or leaks due to cracking. In addition, structures such as concrete blocks are likely to be permeable and need to be changed to impermeable. At this time, waterproofing agent is used for the purpose of imparting waterproofing property to concrete or preventing cracks and leaks. The waterproofing agent has various kinds such as inorganic type or organic type, but if classified according to chemical composition, it is based on calcium chloride type, sodium silicate type, fatty acid type, Paraffin-based, high-molecular emulsion-based, water-reducing agent and the like can be divided into a typical one of the paraffin-based and the polymer is an aqueous dispersion siliceous fine powder, the former absorbs water in the cement or dried to solidify in concrete water repellent This is because the latter forms an impermeable layer, and the latter is a so-called pozzolanic reaction, in which water-soluble calcium hydroxide in the concrete reacts with silicic acid and water to form insoluble calcium silicate hydrate, which makes the structure dense.
그러나, 이들중 강알카리성은 시멘트에 급결성을 부여하지만 동시에 시멘트의 강도를 저하시켜 그 수명을 반감케 하는 원인이 되며, 계면활성제와 같이 친수성이 있을 경우, 시멘트 입자간의 결속력을 저해하는 결과가 되어 구축물의 수명을 단축시키는 단점이 있다.However, among these, strong alkalinity imparts fastness to cement but at the same time causes the strength of the cement to decrease by half, and when hydrophilic such as a surfactant is used, the cohesion between cement particles is inhibited. There is a disadvantage of shortening the life of the construct.
본 발명은 이러한 문제점을 해결하기 위하여, 천연 포졸란의 일종인 제올라이트(Zeolite, 拂石)를 함유케하여 제올라이트의 화학적 특성인 수분흡수성, 흡착성, 이온 교환성과 물리적 특성인 다공성 결정구조에 의한 강도증진 및 수밀성 향상등의 상승작용을 이용하여 우수한 방수성과 작업성 및 가공성이 우수한 콘크리트용 방수제를 제조하는데 그 목적이 있다.In order to solve this problem, the present invention contains a zeolite (Zeolite), a kind of natural pozzolanic, to enhance the strength by porous crystal structure of water absorption, adsorption, ion exchangeability and physical properties of the zeolite The purpose is to produce a waterproofing agent for concrete having excellent waterproofness, workability and workability by using synergy such as watertightness improvement.
지금까지 실리카와 알루미나가 결합된 결정성구조를 갖는 천연 포졸란(Pozzolana)의 일종인 제올라이트를 가지고 콘크리트용 방수제를 제조한 예는 없다.Until now, there is no example of manufacturing a waterproofing agent for concrete with zeolite, which is a kind of natural Pozzolana having a crystalline structure in which silica and alumina are combined.
본 발명 방수제에 사용하는 제올라이트(zeolite)는 제1도에 나타난바와 같은 X선 회절무늬(pattern)와 제2도에서와 같은 적외선 스펙트럼을 갖고 있으며 이를 분석하여 보면, 클리노프틸로라이트(clinoptilolite)를 주성분으로 하고 모데나이트(mordenite), 몬트모릴로나이트(montmorillonite)와 석영이 각각 소량씩 함유되어 있다(표 1 참조).The zeolite used in the waterproofing agent of the present invention has an X-ray diffraction pattern (pattern) as shown in FIG. 1 and an infrared spectrum as shown in FIG. 2, and when analyzed therein, clinoptilolite The main ingredient is mordenite, montmorillonite and quartz in small amounts (see Table 1).
본 발명에 사용하는 천연 제올라이트(zeolite)의 화학성분을 분석한 결과는 다음과 같다.The results of analyzing the chemical composition of the natural zeolite (zeolite) used in the present invention are as follows.
클리노프틸로라이트의 결정구조는 단사정계(monoclinic)이고, 단위세포의 화학식은 Na6[(AlO2)6(SiO2)30]·24H2O로 표시되고, 공도의 크기는 3-5Å이며, 특히 CO2, O2, 및 H2O등을 쉽게 흡착할 수 있고, 공기중 70℃까지는 열적으로 매우 안정하다.The crystal structure of clinoptilolite is monoclinic, and the chemical formula of the unit cell is represented by Na6 [(AlO2 )6 (SiO2 )30 ] · 24H2 O, with a pore size of 3-5 kV. In particular, CO2 , O2 , H2 O and the like can be easily adsorbed, and are very thermally stable up to 70 ° C. in air.
한편, 모데나이트는 결정구조가 정방정계(orthorhombic)이고, 단위세포의 화학식은 Na8.7[(AlO2)8.7(SiO2)39.3]·24H2O이며, 공도의 크기는 약 6.2Å정도이다.On the other hand, mordenite has an orthorhombic crystal structure, the chemical formula of the unit cell is Na8.7 [(AlO2 )8.7 (SiO2 )39.3 ] · 24H2 O, and the pore size is about 6.2 kPa.
본 발명에 사용하는 나트륨염은 물에 잘 녹으며 낮은 어느점을 가지고 있기때문에 겨울공사에서도 잘 얼지 않게 된다. 또한 콘크리트의 요구 특성에 따라 나트륨염의 사용량은 각각 다르지만 보통 30%용액이 사용된다. 소량 사용할 때 이들만의 존재는 정상적인 감수효과를 나타내고, 다량 사용할 때는 지연 감수효과를 나타난다. 소량을 염화칼슘(CaCl2)과 혼합하면 거의 색이 없고 침전이 없는 용액으로 급결 감수한다.Sodium salt used in the present invention is well soluble in water and because it has a low point does not freeze well in winter construction. In addition, although the amount of sodium salt used varies depending on the required characteristics of concrete, a 30% solution is usually used. The presence of only them when used in a small amount shows a normal susceptibility effect, and delayed susceptibility effect in a large amount. When a small amount is mixed with calcium chloride (CaCl2 ), the solution is quenched with a solution that has almost no color and no precipitate.
