Description

산업 폐기물을 이용한 건설자재와 그 제조방법{Construction Materials using industrial waste and the manufacturing method}Construction materials using industrial waste and its manufacturing method

본 발명은 산업 폐기물을 이용한 건설자재와 그 제조방법에 관한 것으로, 더욱 상세하게는 산업 폐기물인 PE, PP, PYC 농업비닐, RPF & RDF(폐기물 플라스틱 고형원료) 등을 1차 파쇄하여 녹인 후 하수 슬러지, 폐석회, 모래, 석분으로 이루어진 군 중에서 선택된 1종 이상과 산화철, 황토로 이루어진 군 중에서 선택된 1종 이상을 혼합하여 압출 또는 금형 프레스에 압축하여 경계석, 보강토, 잔디블록, 호안블록, 인도블록, 맨홀 등으로 사용하는 산업 폐기물을 이용한 건설자재와 그 제조방법에 관한 것이다.
The present invention relates to construction materials using industrial wastes and a method for manufacturing the same, and more specifically, waste, PE, PP, PYC agricultural vinyl, RPF & RDF (waste plastic solid raw materials), and the like after primary crushing and melting. Combining at least one selected from the group consisting of sludge, waste lime, sand, and lime powder with at least one selected from the group consisting of iron oxide and loess, and compressing it in an extrusion or mold press to produce boundary stones, reinforcement soils, grass blocks, shore blocks, and sidewalk blocks. The present invention relates to a construction material using industrial waste used as a manhole, and a manufacturing method thereof.

일반적으로 도로용 경계석이나 보강토, 잔디블록, 호안블록, 인도블록, 맨홀 등의 건설자재는 시멘트와 모래, 자갈 그리로 물을 일정비율로 적절하게 혼합한 다음, 혼합물을 거푸집에 부어 성형한 후 건조하고, 건조된 성형품을 탈형하여 양생하는 과정을 거쳐 제조된 시멘트 콘크리트 재질을 사용하여 왔다.In general, construction materials such as road boundary stone, reinforcement soil, grass block, coastal block, sidewalk block, manhole, etc. are mixed with cement, sand, gravel, and water at a certain ratio, and then the mixture is poured into formwork and dried. In addition, a cement concrete material manufactured by demolding and curing the dried molded product has been used.

그러나 시멘트 콘크리트 재질은 수분흡수율이 매우 높기 때문에 수분의 흡수 및 증발과정이 반복적으로 일어나 노화현상을 촉진시키며, 그에 따라 강도가 저하되어 약간의 충격에도 쉽게 파손되거나 균열이 발생하는 단점을 가지고 있다.However, the cement concrete material has a very high water absorption rate, so that the absorption and evaporation process of water repeatedly occurs, thereby promoting aging, and thus, the strength is lowered, so that it is easily broken or cracked even with slight impact.

이러한 단점으로 인하여 교체가 빈번하게 이루어지고 있으며, 그 결과 보행자나 교체 작업이 이루어지는 주변을 이용하는 사람들에게 많은 피해를 주고 있는 실정에 있다.
Due to these shortcomings, replacements are frequently made, and as a result, there are many situations in which pedestrians or people using the surroundings are replaced.

한편, PE, PP, PYC 농업비닐 등과 같은 합성수지 제품의 사용이 증가함에 따라서 버려지는 폐기물의 처리가 점점 더 중요한 문제로 부각되어 있다, 이에 따라 다양한 방식으로 폐기물을 재활용하는 방안이 제시되고 있는데, 현실적으로 폐기물의 회수 및 분류, 세척 등, 전처리에 소요되는 비용이 상당하기 때문에, 매우 많은 양의 폐기물이 제대로 활용되지 못하고 버려지고 있다. 따라서 보다 간한 전처리 공정을 통해 폐기물을 재활용하여 사용할 수 있는 현실적 방안이 요구되고 있는 실정이다.
On the other hand, as the use of synthetic resin products such as PE, PP, PYC agricultural vinyl, etc. increases, disposal of discarded waste is becoming more and more important problem. Therefore, there are various ways to recycle waste. Since the cost of pretreatment such as recovery, sorting and washing of waste is considerable, very large amounts of waste are not properly utilized and discarded. Therefore, there is a need for a realistic way to recycle waste through a simpler pretreatment process.

일반적으로 RPF(refuse plastic fuel)와 RDF(refuse derived fuel)는 폐기물에서 얻어지는 연료라는 뜻으로 폐기물에 함유된 수분과 금속류, 유리 등의 불연성분을 건조, 파쇄, 선별 등의 공정을 통하여 제거하고 가연성 분말을 가공하여 만든 고체연료이다.In general, RPF (refuse plastic fuel) and RDF (refuse derived fuel) are fuels obtained from waste, and the non-combustible components such as moisture, metals, and glass contained in the waste are removed through drying, crushing, screening, and flammability. Solid fuel made by processing powder.

이러한 폐기물 플라스틱 고형원료인 RPF & RDF는 주로 소각시설에서 소각에 의한 발전, 열을 이용하여 에너지 효율을 이용하는 기술로 사용되고 있으나, 소각이 아닌 다른 목적으로 재활용하는 경우는 극히 드물어 자원의 활용성이 낮은 결점이 있었다.
RPF & RDF, which is a solid material for waste plastics, is mainly used in incineration facilities as a technology that utilizes energy generation and heat by incineration, but is rarely recycled for purposes other than incineration. There was a flaw.
