2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
테라조는 오랜 시간 바닥의 마감에 이용되어 왔다. 그 견고성과 아름다움 그리고 관리의 편리성 등으로 인해 상업용이나 대규모 인원이 출입하는 건물에는 거의 표준으로 시공되어 왔다고 해도 과언이 아니다. 이런 테라조는 다른 건축자재와 마찬가지로 그 기술이 지속적으로 발달해 자재의 개선도 뚜렷이 변화하여 왔고, 원료의 배합 방법이나 시공 방법에 있어서도 매우 광범위하게 발달하여 왔으며, 아름다움과 용도의 충족을 동시에 만족시킬 만큼 기술이 발달한 오늘날, 그 사용 범위 또한 대단히 확대되고 있다. 그러나 테라죠는 제조 특성 및 용도에 의해 대부분이 고분자 수지를 주재료로 하여 제조되어 왔으며, 일부 시멘트 재료를 사용하기도 한다. 최근 건축물의 소방, 피난 구조법이 개정되면서 건축물에서는 내화, 난연 특성을 강조하게 되었으며 이를 법으로 강력하게 규제하고 있다. 이러한 건축물의 관련 법규의 개정에 따라, 열에 약한 고분자 수지는 사용이 불가능할 것으로 예측되고 있으며, 따라서 고분자 수지를 주재료로 한 수지계 테라죠는 사용이 불가할 것이다. 따라서 시멘트 계 테라죠의 사용이 더욱 활발해 질 것이다. 그러나 시멘트계 테라죠는 시멘트 재료의 수화 특성상 두께 25 밀리미터 이하로는 제조하기가 불가능하거나 유압식 프레스법에 의한 제조로 인하여 시설비의 막대한 투자로 인하여가격이 급격히 상숭할 것이다. 본 발명은 이러한 시멘트계 테라죠의 제조에 대한 문제점을 해결하기 위해, 고강도, 고유동성의 특징을 갖는 그라우트재를 한층 더 발전 시켜 수축에 의한 균열이 발생하지 않는 박막형 시멘트 테라죠의 제조에 관한 것이다.Terrazzo has been used for floor finishing for a long time. Because of its robustness, beauty, and ease of management, it is no exaggeration to say that it has been almost standardly installed in commercial and large-scale buildings. Like other building materials, these terrazzos have continuously developed their technology, and the improvement of materials has been clearly changed. The terrazzo has also been developed extensively in the method of mixing raw materials and construction, and satisfying both beauty and use at the same time. Today, as technology advances, the scope of its use is also greatly expanded. However, Terrajo has been manufactured mainly from polymer resins, and some cement materials, depending on the manufacturing characteristics and uses. With the recent revision of the Fire and Evacuation Rescue Act on buildings, the building has emphasized fire and flame retardant characteristics and is strongly regulated by the law. According to the revision of relevant building regulations, it is predicted that thermally weak polymer resins cannot be used, and therefore, resin-based terrazzos based on polymer resins cannot be used. Therefore, the use of cement-based terrazzo will be more active. However, cement-based terrazzo will not be able to be manufactured under the thickness of 25 millimeters due to the hydration characteristics of cement materials, or the price will rise rapidly due to the huge investment of facility cost due to the manufacturing by the hydraulic press method. The present invention relates to the production of a thin-film cement terrazzo, in order to solve the problem of the production of cement-based terrazzo, to further develop a grout material having high strength and high flowability characteristics, so that no cracking due to shrinkage occurs.

Description
본 발명은 고강도 시멘트 그라우트재를 사용하여 내마모성, 고강도, 수축에 의한 균열 발생이 없는 슬립 캐스팅(slip casting)형 또는 유압 프레스 형 시멘트 테라죠의 제조에 관한 것이다. 테라조는 오랜 시간 바닥의 마감에 이용되어 왔다. 그 견고성과 아름다움 그리고 관리의 편리성 등으로 인해 상업용이나 대규모 인원이 출입하는 건물에는 거의 표준으로 시공되어 왔다고 해도 과언이 아니다. 이런 테라조는 다른 건축자재와 마찬가지로 그 기술이 발달해 왔으며 자재의 개선도 뚜렷이 변화하여 왔으며, 원료의 배합 방법이나 시공 방법에 있어서도 매우 광범위하게 발달하여 왔으며 아름다움과 용도의 충족을 동시에 만족시킬 만큼 기술이 발달한 오늘날, 그 사용의 범위 또한 대단히 확대되고 있다. 일반적으로 테라죠는 다음과 같이 구분되어 사용해 왔다.The present invention relates to the production of slip casting type or hydraulic press type cement terrazzo using high strength cement grout material, which is free of abrasion resistance, high strength, and shrinkage due to shrinkage. Terrazzo has been used for floor finishing for a long time. Because of its robustness, beauty, and ease of management, it is no exaggeration to say that it has been almost standardly installed in commercial and large-scale buildings. Like other building materials, these terrazzos have developed their technology, and the improvement of materials has also been clearly changed. The terrazzo has also been developed extensively in the method of mixing raw materials and construction, and the technology is sufficient to satisfy both beauty and use. In today's development, the scope of its use is also greatly expanded. In general, Terrajo has been divided into the following:
1. 일반적인 얇은 테라조 : 가장 오랜 시간동안 가장 광범위하게 사용된 방법으로 옥시클로라이드 조성의 테라조.1. General thin terrazzo: Terrazzo with oxychloride composition in the most widely used method for the longest time.
2. 일체식 테라조(모노리틱 테라조) : 경화되지 않은 콘크리트 바닥 위에15.6 밀리미터 정도의 두께로 테라조를 조성하는 방법.2. Integral terrazzo (monolitic terrazzo): A method of forming terrazzo with a thickness of about 15.6 millimeters on an uncured concrete floor.
3. 일체식과는 달리 완전히 경화된 콘크리트 면 위에 15.6 밀리미터 정도 두께의 얇은 테라조를 조성하면서 콘크리트 면과의 접착을 완벽하게 하기 위해 화학적 접착제(Chemical Adhesive)를 사용하는 방법으로 거의 일체식과 비슷하다.3. Unlike the one-piece, it is almost similar to the one-piece method by using a chemical adhesive to form a thin terrazzo about 15.6 millimeters thick on the fully hardened concrete surface and perfect adhesion to the concrete surface.
4. 경화된 콘크리트 면 위에 화학적 접착제 대신에 높은 인장성과 유연성을 부여하기 위해 에멀젼을 사용하는 방법.4. A method of using emulsions to give high tensile and flexibility in place of chemical adhesives on hardened concrete surfaces.
5. 경화된 콘크리트 면 위에 구체로서 합성레진이나 폴리머를 사용하는 방법으로 일반적인 테라조와는 전혀 다른 성질의 테라조.5. The terrazzo, which is completely different from the terrazzo, using synthetic resin or polymer as a sphere on the hardened concrete surface.
상기의 테라죠 방법 중에서 현재는 주로 성형품으로 사용되고 있으며, 대부분의 박막형(20 밀리미터 이하) 테라죠는 고분자 수지를 사용하고 있다. 그러나 건축물의 소방 피난법의 개정 및 화재시의 유독 개스의 분출을 방지하기 위하여 최근에는 무기질의 내화, 난연재료로 구성된 테라죠가 요구되고 있다. 이러한 시대적인 요청에 의하여 무기질인 시멘트 테라죠가 사용되고 있으나, 시멘트의 특성 상 박막형 테라죠의 제조는 요원하기만 하다. 시멘트는 일반적으로 물에 의해 경화하나 경화 시 잉여의 물의 건조에 의한 수축으로 균열이 발생한다. 이때 발생되는 균열은 미장 마감재로서의 테라죠에 치명적인 결함이 된다. 이러한 건조수축에 의한 균열을 방지하기 위하여 유압에 의한 프레스법이 도입되기도 하나 역시 제조시의 파손율로 인하여 박막형 테라죠로는 사용하지 못하고 27밀리미터 이상의 후막형 테라죠로 일부 사용되고 있다. 대한민국 공개특허 특 1998-0009698에서는 고분자 수지를 사용하지는 않으나 배합된 재료를 사용하고자 하는 장소에 타설 후 습식 연마를 하는 것에 대한 내용으로 이미 사용자들이 환경오염 등의 이유로 사용하지 않는 시공현장에서의 습식 연마를 택하고 있는 문제점이 있으며, 대한민국 공개특허 특1997-0015514 역시 시멘트 중에서 백시멘트를 사용하나, 역시 사용 현장에서 습식 연마를 택하고 있다. 이러한 인조석 현장 물갈기(일명 도끼다시)는 건설 현장의 환경 오염 등의 이유로 수년전부터 사용하지 않는 재료 및 시공법으로 규정되어 있다.Among the terazzo methods, the terazzo is currently mainly used as a molded product, and most of the thin-film type (less than 20 millimeters) terazzo use polymer resin. However, in order to prevent the revision of the firefighting evacuation law of buildings and the emission of toxic gases during a fire, terrazzo, which is composed of mineral fire and flame retardant materials, has recently been required. At this time, the inorganic cement terrazzo is used, but the production of thin film terrazzo is difficult for the characteristics of cement. Cement is generally hardened by water, but when hardened, cracking occurs due to shrinkage caused by drying of excess water. The crack generated at this time is a fatal defect in the terrazzo as a plaster finish. In order to prevent such cracks caused by dry shrinkage, a hydraulic press method is introduced, but due to the breakage rate during manufacturing, it is not used as a thin film terrazzo but is used as a thick film terrazzo of 27 mm or more. Korean Patent Laid-Open Publication No. 1998-0009698 does not use a polymer resin, but wet polishing after placing it in a place where a compounded material is to be used. There is a problem in that it is selected, Republic of Korea Patent Publication No. 1997-0015514 also uses a back cement in the cement, but also to use wet polishing at the site of use. This artificial stone site change (aka axdashi) is prescribed by materials and construction methods that have not been used for several years because of environmental pollution on construction sites.
따라서, 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 주재료로 일반 포트란드 시멘트, 물 시멘트 비를 줄이기 위한 고유동성 재료의 사용 및 수축 균열을 방지하기 위한 시멘트 팽창재의 사용 등으로 구성된 조성물과 공지의 종속을 혼합하고 유압 성형법 및 슬립 캐스팅 방법에 의하여 성형하고, 양생한 후, 습식 연마를 통하여 내마모성, 고강도, 무균열 및 고 광택성을 발휘하는 박막형 시멘트 테라죠의 제조에 관한 것이다.Accordingly, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to prevent the use of high fluidity materials and shrinkage cracks for reducing the general cement cement, water cement ratio as the main material A thin-film cement terrazzo that mixes a composition consisting of the use of a cement expander with a known subordinate, and is molded by a hydraulic molding method and a slip casting method, cured, and then subjected to wet polishing to exhibit wear resistance, high strength, no cracking, and high gloss. It is about the manufacture of jaws.

After curing in air for about 2 to 3 days, the mold is demolded in a container and wet-polished with a polishing machine to polish the surface.
실시예 2Example 2
실시예 2에서는 1000kg의 배합량을 배합한다고 할 때, 시멘트 450kg과, 나프탈렌-설포네이트계 고유동화제 12 kg, 고강도성을 발휘하기 위한 실리카 흄 60 kg, 그리고 시멘트 팽창재 70kg, 백운석계 종속 408kg과 물의 량 130 kg을 고르게 혼합한 후 용기에 넣어 진동기로 고르게 다짐을 한다. 다짐이 완료 된 것을 대기 중에서 유압 프레스로 성형한 후, 충분히 양생시킨다. 공기 중에서 약 2일 내지 3일 양생한 후 용기에서 탈형하여, 연마기로 습식 연마하여 표면에 광택을 낸다.In Example 2, when a compounding amount of 1000 kg is blended, 450 kg of cement, 12 kg of naphthalene-sulfonate-based high softening agent, 60 kg of silica fume for high strength, 70 kg of cement expander, 408 kg of dolomite-based submerged water, Mix 130 kg evenly and put into container to compact evenly with vibrator. After the compaction is completed, it is molded in a hydraulic press in the air and sufficiently cured. After curing in air for about 2 to 3 days, the mold is demolded in a container and wet-polished with a polishing machine to polish the surface.
상기와 같은 본 발명의 테라죠의 효과를 검증하기 위하여 각 실시예 별로 시험을 수행하였다. 여기서, 실시 예 별로 제조한 시편의 크기는 400×400×18 (단위: 밀리미터)로 하였으며, 시험방법은 KS F 4739-1999로 하였다. 표1에 시험결과를 나타내었다.In order to verify the effect of the terrazzo of the present invention as described above, tests were performed for each example. Herein, the size of the specimens prepared for each example was 400 × 400 × 18 (unit: millimeter), and the test method was KS F 4739-1999. Table 1 shows the test results.
본 발명의 시멘트 테라죠는 일반 수지계 테라죠 및 후막형 시멘트 테라죠의 물리적 성질과 비교하여 전혀 차이가 없는 것을 알 수 있다. 일반 시멘트 계 테라죠의 경우 시멘트의 건조수축에 의해 표면 균열, 뒤틀림, 변형이 발생하기 때문에 20밀리미터 이하의 박막형 테라죠는 제조할 수 없으나, 본 발명의 시멘트 테라죠는 건조수축에 의한 물의 량을 줄이고, 수축에 의한 균열을 방지하고, 고강도성을 발현함으로서 일반 시멘트계 테라죠와는 달리 20밀리미터 두께의 성형품에서도 건조수축에 의한 균열 및 뒤틀림이나 변형이 전혀 없다.The cement terrazzo of the present invention can be seen that there is no difference at all compared to the physical properties of the general resin-based terrazzo and thick-film cement terrazzo. In the case of general cement terrazzo, the surface crack, distortion, and deformation are caused by dry shrinkage of cement. Therefore, the thin film terrazzo of 20 mm or less cannot be manufactured. However, cement terrazzo of the present invention reduces the amount of water by dry shrinkage. By reducing, preventing cracks due to shrinkage, and expressing high strength, there is no crack, distortion or deformation due to dry shrinkage even in a 20 mm thick molded article unlike general cement terrazzo.
