Description
본 발명은 콘크리트 슬러지의 가공방법에 관한 것으로, 더욱 상세하게는 산업현장에서 폐기되어 수질이나 토양을 오염시키는 콘크리트 슬러지를 재활용이 가능하도록 가공처리함으로써, 환경의 오염을 방지하고 콘크리트 폐기물을 자원화할 수 있는 콘크리트 슬러지의 가공방법에 관한 것이다.The present invention relates to a method for processing concrete sludge, and more particularly, by processing the concrete sludge that can be disposed of in an industrial site to contaminate water quality or soil to be recycled, thereby preventing environmental pollution and recycling concrete waste. The present invention relates to a method of processing concrete sludge.
콘크리트 슬러지는 레미콘 공장이나 흄관 공장 등, 콘크리트 2차 제품을 생산하거나 콘크리트를 사용하여 구조물 등을 제조하는 업체에서 폐기물로서 발생되는 처리 곤란한 물질이다. 왜냐하면, 콘크리트 슬러지는 일반적으로 pH가 11이상이 되며, 일반 시멘트와 혼합하여도 그 강도가 매우 낮을 뿐만 아니라 성형성도 없어서 사용하기에 곤란하기 때문이다. 그러므로, 슬러지가 생산되는 업체에서는 슬러지의 처리를 위하여 막대한 비용을 들여서 매립하거나 산업 폐기물로 처리하고 있다. 따라서, 슬러지 처리에 있어서 경제적으로 큰 어려움을 겪고 있으며, 최근에는 환경 보호를 위한 법적인 제한으로 인하여 그 처리에 있어서 어려움이 가중되고 있다.Concrete sludge is a material that is difficult to process as waste in companies that produce secondary concrete products, such as ready-mix concrete plants or fume pipe plants, or manufacture structures using concrete. This is because concrete sludge generally has a pH of 11 or more, and even when mixed with general cement, its strength is very low and it is difficult to use because it is not formable. Therefore, companies that produce sludge have a huge cost for disposal of the sludge, which is landfilled or disposed of as industrial waste. Therefore, there is a great economic difficulty in the sludge treatment, and in recent years, due to legal restrictions for environmental protection, the difficulty in the treatment is increased.
국내의 많은 연구 기관에서는 콘크리트 슬러지의 처리방법을 다각도로 연구하고 있으나, 현실적으로 적용하기 어려운 방법만이 제시되어 왔다. 또한, 해외의 선진국에서도 일부학자들이 콘크리트 슬러지의 재활용 방법에 대하여 많은 시간과 정렬을 바치고 있으나, 해외에서 수행되는 연구는 국책 과제로 수행되고 연구 결과가 해당국의 산업 기밀로 보호되고 있으므로, 그 결과의 국내 활용은 불가능한 실정이다.Many research institutes in Korea are studying the treatment method of concrete sludge from various angles, but only methods that are difficult to apply in reality have been proposed. In addition, even in advanced countries, some scholars devote a lot of time and alignment to the recycling method of concrete sludge, but the research conducted abroad is carried out as a national project and the results of the research are protected by the industrial secrets of the country. Domestic use is not possible.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은, 산업 현장에서 쏟아져 나오는 콘크리트 슬러지를 재활용이 가능하도록 가공처리함으로써, 높은 pH를 갖는 콘크리트 슬러지를 매립할 때 발생하는 지하수의 오염 및 토양의 오염을 미연에 방지할 수 있고, 콘크리트 폐기물의 자원화를 가능하게 하는 콘크리트 슬러지의 가공방법을 제공하려는 것이다.The present invention has been made to solve the conventional problems as described above, the object of the present invention, by processing the concrete sludge pouring from the industrial site to be recycled, it occurs when the concrete sludge having a high pH landfill To prevent the contamination of groundwater and soil pollution in advance, and to provide a concrete sludge processing method that enables the recycling of concrete waste.

이상에서 언급한 바와 같이, 본 발명에서는, 국내 콘크리트 산업 현장에서 쏟아져 나오는 콘크리트 슬러지를 재활용이 가능하도록 가공처리함으로써, 지하수의 수질 환경 뿐만 아니라, 토양의 오염을 방지할수 있게한다.As mentioned above, in the present invention, by processing the concrete sludge pouring from the domestic concrete industrial site to be recycled, it is possible to prevent contamination of the soil as well as the water quality environment of groundwater.
이하, 본 발명의 바람직한 실시 예에 따른 콘크리트 슬러지의 가공방법을 보다 상세하게 설명한다.Hereinafter, a method of processing concrete sludge according to a preferred embodiment of the present invention will be described in more detail.
일반적으로, 콘크리트 슬러지는 발생 당시에 많은 양의 물을 함유하며, 발생된 슬러지는 물과 함께 집수조에 집수되어 침전과정을 거친다. 침전된 슬러지는 페로다 등의 장비를 이용하여 대형 운송장치에 실려서 일반 쓰레기로 매립되거나 산업 폐기물로 처리된다.In general, concrete sludge contains a large amount of water at the time of occurrence, and the sludge generated is collected in a sump together with water and subjected to precipitation. Precipitated sludge is loaded into large-scale transportation equipment using equipment such as ferodas and landfilled as general waste or industrial waste.
이때, 침전 과정에서 침전의 속도와 용액의 중화를 위하여 황산을 사용하는 경우도 있다. 황산을 첨가하면 용액의 액성은 중성화된다. 따라서, 얻어진 폐슬러지 침전물의 액성은 중성이거나 강한 알칼리성이며, 다양한 입도의 분말 형태 슬러지를 물에 반죽시켜 놓은 상태로 얻어진다.In this case, sulfuric acid may be used for the rate of precipitation and neutralization of the solution during the precipitation process. The addition of sulfuric acid neutralizes the liquidity of the solution. Therefore, the liquidity of the waste sludge obtained is neutral or strong alkaline, and is obtained in a state in which powdered sludge of various particle sizes is kneaded in water.
본 발명은 이를 건조시켜서 사용하는 것으로, 먼저 이들 반죽상태 물질을 원심분리기 또는 건조로를 이용하여 완전히 건조시킨다. 건조된 슬러지는 덩어리 형태를 유지하지만 강도는 매우 낮다. 건조된 슬러지는 분쇄기를 이용하여 곱게 분쇄한다. 슬러지를 분쇄하는 동안에 폴리비닐아세테이트(에틸렌 비닐 아세테이트)와 같은 콘크리트 접착제, 종이 펄프나 볏짚을 잘게 분쇄시킨 혼화재료, 또는 폴리에틸렌이나 폴리스티렌과 같은 고분자를 혼합하여 높은 압력에서 성형한다. 압축 성형 강도가 클수록 고강도의 제품을 얻을 수 있고 성형성도 우수하다.The present invention is to use it by drying, first, these dough-like material is completely dried using a centrifuge or drying furnace. Dried sludge retains lump form but has a very low strength. The dried sludge is finely ground using a grinder. During sludge milling, a concrete adhesive such as polyvinylacetate (ethylene vinyl acetate), a blend of finely pulverized paper pulp or rice straw, or a polymer such as polyethylene or polystyrene is mixed and molded at high pressure. The greater the compression molding strength, the higher strength the product can be obtained and the better the moldability.
이때, 종이 펄프나 볏짚과 같은 다공성 물질을 혼합하여 압축 성형하면, 단열성이 크고 압축강도 뿐만아니라 인장 강도가 우수한 제품을 얻을 수 있다. 또한, 슬러지와 함께 폴리에틸렌이나 폴리스티렌과 같은 고분자를 혼합하여 압축 성형하면, 물에 강한 물질이 얻어진다. 이와는 달리, 순수한 슬러지만을 이용하여 압축 성형하면, 열전도성이 우수한 제품이 얻어진다. 그러므로, 용도에 따라서 이들 제품을 다양하게 성형하여 사용할 수 있다.In this case, when a compression molded by mixing a porous material such as paper pulp or rice straw, it is possible to obtain a product having excellent thermal insulation properties and excellent tensile strength as well as tensile strength. In addition, by mixing a sludge with a polymer such as polyethylene or polystyrene and compression molding, a substance resistant to water is obtained. On the other hand, by compression molding using only pure sludge, a product having excellent thermal conductivity is obtained. Therefore, these products can be molded and used in various ways depending on the application.
이렇게 성형되어 얻어진 제품을 건조시키면 건축용 자재로 사용할 수 있다.When the product obtained by molding is dried, it can be used as a building material.
이상에서 얻어진 제품의 표면에 혐수성 물질 등을 분무하거나 표면 처리함으로써, 건축물의 외장재로도 사용이 가능하다.By spraying or surface-treating a hydrophobic substance etc. on the surface of the product obtained above, it can be used also as a exterior material of a building.
이상에서 살펴본 바와 같이 본 발명에 따라서 처리된 제품은 화기에 강한 콘크리트 슬러지를 활용하여 성형하므로, 내화성이 대단히 우수하다.As described above, the product treated according to the present invention is molded using a strong concrete sludge for fire, so it is very excellent in fire resistance.
하기에서는 본 발명에서 사용되는 콘크리트 슬러지의 압축 성형 방법을 간략하게 설명한다.The following briefly describes the compression molding method of concrete sludge used in the present invention.
먼저, 콘크리트 슬러지를 만들고자하는 형태의 거푸집(몰드)을 만들어 여기에 전술한 바와 같은 슬러지와 다른 혼화재료를 잘 혼합하여 채우고, 약 100 ∼ 1,000kg/cm2의 높은 압력으로 1∼10분 정도 가압함으로써 거푸집내에 압력이 골고루 전달될 수 있게 한다. 필요에 따라서 고급 제품을 만들기 위하여 여기서 성형된 제품을 유압 압축기를 이용하여 기름과 같은 유체내에서 재성형하는 경우도 있다.First, form the mold (mold) to form the concrete sludge, and then mix and fill the sludge and other miscible materials as described above, and pressurized for about 1 to 10 minutes at a high pressure of about 100 ~ 1,000kg / cm 2 This allows pressure to be evenly distributed within the formwork. If necessary, the molded product may be remolded in a fluid such as oil using a hydraulic compressor to make a high quality product.
압축성형시 콘크리트 접착제로 사용되는 폴리비닐아세테이트(EVA류)와 같은 물질은 슬러지 질량의 약 0.1∼20% 범위를 사용하는 것이 바람직하며, 종이 펄프나 볏짚과 같은 물질은 슬러지 질량에 어떤 비율로도 혼합이 가능하다. 이와같은 물질의 혼합비율은 성형되어 얻어지는 제품의 용도에 따라 변화될 수 있으며, 압축성형 강도 등이 정하여진다. 또한, 혼합되는 혼화재료의 입도 등도 용도에 따라 결정될 수 있다. 일반적으로, 압축 성형성은 혼화재료의 입도가 작을수록 좋으며, 섬유가 가늘면서 길고 질길수록 성형된 제품의 인장 강도가 크게 얻어진다.Materials such as polyvinylacetate (EVA), which are used as concrete adhesives for compression molding, should be used in the range of about 0.1 to 20% of the mass of sludge. Mixing is possible. The mixing ratio of such materials may vary depending on the use of the product obtained by molding, and the compression molding strength is determined. In addition, the particle size and the like of the mixed materials to be mixed may be determined according to the use. In general, the compression moldability is better the smaller the particle size of the mixed material, the longer the fibers are thin and long, the greater the tensile strength of the molded product.
한편, 압축 성형되어 얻어진 제품은 표면이 높은 압력으로 성형되었으나, 건조된 상태에서 표면의 분말이 일부 묻어나올 수 있다. 따라서, 제품의 상품성을 증진시키고 취급이 편리하도록 표면을 처리하는 방법이 강구되어야한다.On the other hand, the product obtained by compression molding is molded at a high pressure, the surface of the powder may be partially buried in the dried state. Therefore, a method of treating the surface should be devised to enhance the commerciality of the product and to facilitate handling.
예를 들면, 고온에서 열처리함으로써 고체화학 반응을 통하여 처리할 수 있다. 이때, 로내의 처리 온도는 1,000℃∼1,200℃ 범위이며, 1,000℃부근의 저온 영역에서는 장시간의 열처리 시간이 요구된다. 1,200℃ 부근의 고온 영역에서는 비교적 짧은 시간동안에 표면 처리가 가능하고, 시간이나 온도 구배에 따라서 제품의 내부까지 열처리 조절이 가능하다.For example, it can be processed through a solid chemical reaction by heat treatment at a high temperature. At this time, the treatment temperature in the furnace is in the range of 1,000 ° C to 1,200 ° C, and a long heat treatment time is required in the low temperature region near 1,000 ° C. In the high temperature region around 1,200 ℃, surface treatment can be done for a relatively short time, and heat treatment can be controlled to the inside of the product according to time or temperature gradient.
이와는 달리, 표면에 혐수성 제품의 물질을 분무, 건조하거나 방수제 등을 분무, 건조시켜서 물과의 접촉시 직접적으로 물이 침투되지 않도록 처리하는 것도 가능하다. 또다른 방법으로는, 거푸집 내면에 접착제 또는 혐수성의 제품을 성형 압축전에 처리하여 성형 압축과 동시에 표면 처리가 이루어지도록 하는 것이다.Alternatively, it is also possible to spray or dry the material of the hydrophobic product on the surface, or to spray and dry the water repellent, etc., so that the water does not directly penetrate when contacted with water. Alternatively, an adhesive or hydrophobic product is treated on the form inner surface prior to molding compression so that surface treatment is performed simultaneously with molding compression.
이상과 같은 방법으로 압축 성형된 제품을 표면 처리하면, 건축 외장재로도 사용이 가능하다.If the product is compression-molded in the above manner, it can be used as a building exterior material.
실시 예Example
건조된 콘크리트 슬러지 500g을 분쇄하면서 폴리비닐아세테이트(에틸렌 비닐 아세테이트 공중합체) 25g을 첨가하여 슬러지와 골고루 혼합한다. 혼합된 시료 중 일부(150g)를 분취하여 실온에서 직경 70mm의 원형 몰드로 5분간 600kg/cm2의 압력으로 가압 성형하며, 이중의 일부(150g)를 종이 펄프 30g과 혼합하여 앞에서와 같이 성형하며, 또한 일부(150g)를 볏짚 30g과 혼합하여 성형한다. 이상에서 성형된 제품을 건조로를 이용하여 80℃에서 3시간 건조시킨다. 여기까지의 과정을 거쳐서 만든 제품이 표면 처리를 하지 않은 제품이며, 건축 자재나 단열재, 또는 열 전도체 등으로 사용이 가능하다.500 g of dried concrete sludge is pulverized, and 25 g of polyvinylacetate (ethylene vinyl acetate copolymer) is added and mixed with the sludge evenly. A portion of the mixed sample (150 g) was aliquoted and press-molded at a pressure of 600 kg / cm 2 for 5 minutes in a circular mold having a diameter of 70 mm at room temperature. A portion of the mixture (150 g) was mixed with 30 g of paper pulp and formed as described above. In addition, a part (150g) is mixed with 30g of rice straw and molded. The molded product is dried at 80 ° C. for 3 hours using a drying furnace. Products made through the process up to this point are products without surface treatment, and can be used as building materials, insulation materials, or thermal conductors.
여기서, 폴리비닐 아세테이트 (에틸렌 비닐 아세테이트 공중합체)를 과량(5 0∼100g)첨가하면 외장재로서도 대단히 양호하게 사용될 수 있다. 표면에서 분말이묻어나는 제품을 방수액으로 표면 처리한 후 다시 건조하였고, 또한 혐수성 페인트 (락카, 니스 등)로 표면 처리하여 건축물의 외장재를 만들었다. 또한, 초기에 혼화재료가 첨가되지 않은 제품을 1,100℃의 온도에서 2시간 열처리하여 단단한 벽돌을 만들었다.Here, when an excess (50 to 100 g) of polyvinyl acetate (ethylene vinyl acetate copolymer) is added, it can be used very well as a packaging material. The product, which had powder on the surface, was surface-treated with a waterproofing solution and dried again, and the surface of the building was made by surface-treating with a hydrophobic paint (lacka, varnish, etc.). In addition, initially, the product without the admixture was heat-treated for 2 hours at a temperature of 1,100 ℃ to make a solid brick.
이상에서 언급한 바와 같이, 본 발명에 따르면, 국내 콘크리트 산업 현장에서 쏟아져 나오는 콘크리트 슬러지를 재활용이 가능하도록 가공함으로써, 지하수의 수질 환경을 보호할 수 있을 뿐만 아니라, 토양의 오염을 방지할 수 있게된다. 또한, 콘크리트 폐기물을 양호한 방법으로 관리 및 처분할 수 있게 함으로써, 콘크리트 폐기물의 음성적인 폐기를 방지하는 효과를 얻을 수 있고, 환경 처리비용을 절감시킬 수 있다. 게다가, 본 발명에 따른 콘크리트 슬러지 처리 방법을 다른 폐기물 처리에 까지 확장시킬 수 있고, 본 발명에 의해서 제조된 제품은 내화성이 우수하므로 건축용 자재로 활용할 수 있다.As mentioned above, according to the present invention, by processing the concrete sludge pouring from the domestic concrete industry to be recycled, not only can protect the water quality environment of the groundwater, it is also possible to prevent soil contamination. . In addition, by enabling the concrete waste to be managed and disposed in a good manner, it is possible to obtain the effect of preventing the negative waste of the concrete waste, and to reduce the environmental treatment cost. In addition, the concrete sludge treatment method according to the present invention can be extended to other waste treatment, and the product produced by the present invention can be utilized as a building material because of excellent fire resistance.
