건축물은 소음이 적고, 단열이 잘 되며 및 진동에 강해야 한다. 그러나 종래의 건축물의 경우 이러한 모든 조건을 고루 갖춘 경우를 찾기가 쉽지 않다.Buildings should have low noise, good insulation and strong vibration. However, in the case of conventional buildings, it is not easy to find cases where all these conditions are uniform.
한편, 특수한 사용목적이나 환경에 맞도록 여러 가지 특수 콘크리트가 개발되었으나, 이와 같이 여러 가지 조건을 고루 갖도록 하는 것은 쉽지 않다.On the other hand, various special concrete have been developed to meet the specific use purpose and environment, but it is not easy to have various conditions like this.

한편, 국민 생활수준의 급속한 향상과 경제성장으로 인하여 우리나라의 폐기물의 배출은 증가하고 있으며, 근래에 들어 폐기물의 효과적인 처리방법으로 재활 용과 소각에 대한 관심이 높아지고 있으나 아직은 거의 대부분을 매립에 의존하고 있는 실정이다. 특히, 폐주물사는 산업폐기물 분류상 유해폐기물로 분류되어 위생매립 등의 처리를 하여야 하고, 최근의 매립처분비용의 상승과 매립지의 부족 등으로 주물업자에게는 생산원가의 상승요인으로 작용하고 있다. 또 국가환경적인 차원에서는 매립장의 부족문제와 더불어 유용자원의 폐기라는 측면이 있다.On the other hand, due to the rapid improvement of people's standard of living and economic growth, the emission of waste in Korea has been increasing. In recent years, interest in rehabilitation and incineration has been increasing as an effective treatment method of wastes. However, It is true. Especially, the waste ash is classified as hazardous waste in the classification of industrial waste, and sanitary landfill should be treated. In addition, recent increase in landfill disposal cost and shortage of landfill have caused increase in production cost. At the national environmental level, there is a problem of landfill shortage and disposal of useful resources.
더욱이, 폐주물사는 콘크리트용 모래와 거의 같은 특성이 있기 때문에 콘크리트용 재료로서 다양하게 재활용될 수 있다는 특징이 있다.Furthermore, since the waste sand is almost the same as concrete sand, it can be recycled in various ways as a concrete material.
또한, 자동차의 증가에 따라 폐타이어가 증가하여 새로운 환경문제로 대두하고 있는바, 이러한 폐타이어를 환경친화적으로 재활용할 필요성이 대두하고 있다.In addition, as the number of automobiles increases, the number of waste tires increases, which is emerging as a new environmental problem. Therefore, it is necessary to recycle such waste tire environmentally.

슬래그 시멘트는 포틀랜드 시멘트의 반제품인 클링커와 고로 슬래그 및 석고를 각각 또는 조합하여 분쇄하고 일정한 비율로 혼합한 것으로, 일반 포틀랜드 시멘트에 비하여, 장기강도가 높고, 수화열이 낮으며, 화학적 저항성, 내해수성, 내열성, 방수성, 및 안정도가 우수하다는 특징이 있다. 따라서, 본 발명에서는 일반 포틀랜드 시멘트보다는 크랙이 적은 슬래그 시멘트를 사용하는 것이 바람직하다.Slag cement is obtained by crushing clinker, blast furnace slag and gypsum, which are semi-finished products of Portland cement, and mixing them at a certain ratio. It has higher long-term strength and low hydration heat than common portland cement and has chemical resistance, Heat resistance, water resistance, and stability. Therefore, in the present invention, it is preferable to use slag cement having less crack than ordinary Portland cement.
질석(蛭石, Vermiculite)은 단사정계에 속하는 광물로 회백색 또는 갈색이며, 광택이 나고 화학성분은 (Mg, Fe, Al)3(Al,Si)4O10(OH)2·4H2O로 알루미늄·마그 네슘·철의 수산화규산염으로 된 점토광물이며, 굳기 1~2, 비중 2.76인 광물이다. 질석은 저밀도의 다공질(多孔質)이며, 흡수능력이 좋아서 내열재료 및 방음재료로 널리 이용되고 있다. 또한, 소성한 것은 가볍고 내화성이 있으며 흡음(吸音), 단열용 충전재나 시멘트 모르타르의 골재 등으로 사용되기도 한다.Vermiculite is a monoclinic minerals that are grayish white or brownish in color and have a lustrous and chemical composition of (Mg, Fe, Al) 3 (Al, Si) 4 O 10 (OH) 2 .4H 2 O It is a clay mineral composed of aluminum, magnesium, iron hydroxide silicate, hardness 1 ~ 2, specific gravity 2.76. The vermiculite is a porous material having a low density and is widely used as a heat resistant material and a soundproof material because of its excellent absorption ability. Also, the sintered material is lightweight, refractory, and used as a sound absorbing material, a filler for heat insulation, aggregates of cement mortar, and the like.
본 발명은 이러한 질석의 물리, 화학적 성질에 착안하여 개발한 것이다. 즉, 시멘트의 밀도는 약 2300 ㎏/㎤인데 비하여, 질석은 64~160 ㎏/㎤으로 가볍고 공극이 많으며, 내화 및 단열 효과가 우수하다는 점에서 질석을 사용하고, 질석의 공극은 탄성이 있는 폐타이어 분말로 채움으로써 단열효과 및 충격흡수율을 최대화한 것이다.The present invention was developed in consideration of the physical and chemical properties of such vermiculite. That is, the density of cement is about 2300 ㎏ / ㎤, the vermiculite is 64 ~ 160 ㎏ / ㎤, the vermiculite is used in that it is light and has many pores, The tire is filled with powder to maximize the insulation effect and shock absorbing rate.
타이어 분말은 고무의 탄성, 단열성, 절연성, 차음성 등의 성질이 있으며, 진동 및 충격흡수 능력이 뛰어나다. 또한, 폐타이어 분말은 질석의 공극을 채워 단열효과, 소음차단 및 내진성을 극대화하며, 약 200메쉬 이상의 분말을 사용하는 것이 바람직하다. 즉, 본 발명은 버려지고 있는 폐타이어를 자원으로 재생하여 환경오염을 막고, 질석과 함께 혼합되어 단열, 방음, 소음진동을 차단시켜 주는 기능을 한다.The tire powder has properties such as rubber elasticity, heat insulation, insulation, car audio, etc., and is excellent in vibration and shock absorbing ability. In addition, the waste tire powder is filled with the vermiculite pores to maximize the adiabatic effect, noise isolation and vibration resistance, and it is preferable to use a powder of about 200 mesh or more. That is, the present invention regenerates abandoned waste tires as resources to prevent environmental pollution, and mixes with vermiculite to block heat insulation, soundproofing, and noise vibration.
황토 분말은 온도 및 습도 조절효과와, 항균 및 탈취효과가 있으며, 인체에 유용한 효과가 있다고 알려져 있는 원적외선 방출량이 많다는 특징이 있다. 또한, 황토는 다량의 탄산칼슘(CaCO3)을 함유한 황토의 주성분은 실리카 알루미나, 철분, 마그네슘 등으로 구성되며, 또한, 표면이 넓은 벌집 구조로 수많은 공간이 복층구 조로 되어 있어 이 구멍으로 원적외선이 저장 발산하여 황토의 효소 성분에는 카탈라제, 디페놀 옥시다아제, 시카리제, 프로테아제의 4가지 효소가 함유되어 독소제거, 분해력 비료요소, 정화 역할을 하는 황토는 물과 반응하게 되면 각 입자 간의 응집현상으로 약 6%의 체적 감소현상이 일어나며 이것이 균열의 주된 원인이다.The loess powder has temperature and humidity control effect, antibacterial and deodorizing effect, and has a characteristic that there is a lot of far-infrared ray emission which is known to have a useful effect on human body. In addition, yellow loess is composed mainly of silica alumina, iron powder, magnesium and the like, and the main component of the yellow loam containing a large amount of calcium carbonate (CaCO 3 ) is a honeycomb structure having a large surface, As a result of this divergence, the enzymes of the loess are composed of four enzymes such as catalase, diphenol oxidase, sicarase and protease. Sooty loess, which acts as toxin removal, decomposition fertilizer factor and purification, A volume reduction of about 6% occurs, which is a major cause of cracking.
이와 같은 황토에 무수석고를 첨가하면 수화반응을 일으키면서 체적이 팽창되며 이 양자 간의 수축, 팽창작용으로 균열을 억제한다.When anhydrous gypsum is added to such loess, the volume is expanded while causing hydration reaction, and cracks are suppressed by the contraction and expansion action between the two.
무수석고는 시멘트 중의 알루미네이트상과 반응하여 에트링가이트 생성 과정에서 수경성 광물인 칼슘실리게이트상 수화를 촉진하여 수화량 증가하고 화학적 결합수 증대시켜 시멘트 페이스트 중의 공극이 감소하여 고강도 콘크리트 얻을 수 있다. 즉, 무수석고는 슬래그 시멘트와 융합하기 좋도록 CaO, Al2O3의 비율을 3:1로 맞추기 위해 사용된다. 또한, 석고는 시멘트의 응결과 경화시간을 조절하기 위하여 첨가되며, 시멘트 안정성을 좋게 하며 초기강도를 강하게 한다. 그러나 석고를 필요 이상으로 첨가하면 응결시간이 너무 늦어지거나 강도에 좋지 않은 영향을 미치므로 적당양을 사용해야 한다.The anhydrite gypsum reacts with the aluminate phase in the cement to accelerate the hydration of the calcium silicate hydrate, which is a hydraulic mineral, during the process of ettringite formation, thereby increasing the amount of hydration and increasing the number of chemical bonds, thereby reducing the voids in the cement paste and obtaining high strength concrete. That is, anhydrous gypsum is used to adjust the ratio of CaO and Al 2 O 3 to 3: 1 so as to be compatible with slag cement. In addition, gypsum is added to control the setting and curing time of the cement, which improves the cement stability and strengthens the initial strength. However, adding gypsum more than necessary will cause too slow a coagulation time or adversely affect strength, so use appropriate amount of gypsum.
한편, 섬유강화제는 콘크리트의 피로저항성 증대, 휨강도 증대, 전단력, 유연성, 충격저항, 파괴저항의 증가시키는 등 콘크리트의 물리적 성질을 향상시키고, 특히 섬유강화제의 첨가로 균열을 방지하고 강도를 증대시키며 충격저항성을 증대시키는 기능을 한다. 또한, 섬유강화제를 첨가함에 따라 와이어 메쉬 설치 작업이 필요없이 경제성, 시공성, 및 안전성이 확보되고 음극 이온화 차단으로 구조재의 부식을 방지시키는 효과가 있다.On the other hand, the fiber reinforcing agent improves the physical properties of concrete such as increase of fatigue resistance of concrete, increase of flexural strength, shear force, flexibility, impact resistance and fracture resistance. Especially, addition of fiber reinforcing agent prevents cracking, It functions to increase resistance. Further, by adding the fiber reinforcing agent, the wire mesh installation work is not required, and economical efficiency, workability, and safety are ensured and corrosion of the structural material is prevented by blocking the cathode ionization.
상술한 바와 같이, 본 발명은 슬래그 시멘트와, 질석과, 황토분말과, 타이어분말을 혼합하고, 무수석고 및 섬유강화제를 첨가하여, 슬래그 시멘트의 황산염의 화학작용, 내해수성 및 강도증가, 수화열이 작은 장점과, 질석의 단열효과와, 타이어 분말의 탄성 및 충격흡수력과, 황토의 해독력, 습도/온도 조절력 및 열효율성 등의 장점과, 섬유강화제의 특징인 강도 증대 등의 물리적 특징을 향상시키도록 하여, 단열, 방음 및 내진성능을 동시에 향상시킨 것이다. As described above, the present invention relates to a slag cement composition comprising slag cement, vermiculite, loess powder, and tire powder mixed with anhydrous gypsum and fiber reinforcing agent to improve the chemical action of the sulfate of the slag cement, To improve the physical properties such as strength and strength enhancement characteristic of the fiber reinforcing agent as well as advantages such as a small strength, a thermal insulation effect of vermiculite, elasticity and impact absorption power of tire powder, detoxification power of loess, humidity / Thereby improving the heat insulation, soundproofing and seismic performance at the same time.
즉, 본 발명은 슬래그 시멘트에 질석, 황토분말 및 폐타이어 분말을 혼합하고 무수석고, 섬유강화제 및 분말상의 유동화제를 첨가한 가미한 혼합물, 이 혼합물과 동량의 규사 또는 폐주물사를 배합하여 이루어지는 제품으로서, 단열, 방음 및 내진성을 향상시킴과 동시에 콘크리트 타설시의 공정을 단순화하여 인력을 최소화하고 빠른 공정으로 제조할 수 있도록 한 것이다.That is, the present invention relates to a product obtained by mixing vermiculite, loess powder and waste tire powder with slag cement, adding a mixture of anhydrous gypsum, a fiber reinforcing agent and a powdery fluidizing agent, and an equal amount of silica sand or waste rubber, Insulation, soundproofing and vibration proofing, and simplifies the process of concrete pouring, thereby minimizing the manpower and making it possible to manufacture the pouring material by a quick process.
폐주물사는 주물 공장에서 발생하는 폐기물로서 콘크리트용 규사 또는 모래와 거의 같은 특성을 나타내기 때문에 본 발명에서는 폐기물의 자원화로 친환경적 제품을 만들기 위하여 폐주물사를 활용하는 것이 바람직하다.Since the waste foundry is a waste generated in a foundry and exhibits almost the same characteristics as sand or sand for concrete, it is preferable to use a waste stock in order to make an environmentally friendly product by recycling the waste in the present invention.
