산업폐기물 및 토양혼합물의 경화방법Hardening method of industrial waste and soil mixture

본 발명의 근대 산업발전 과정에서 필연적으로 발생하는 산업폐기물 및 토양혼합물을 경화하는 방법에 관한 것으로 더욱 구체적으로 토양은 물론 산업폐기물로 각 공장에서 부산물로 생성되는 소석회, 폐석고, 스레이트생산 및 가공으로 발생하는 오니, 석재 가공오니, 바다 및 개천 바닥의 뻘, 산화철오니 그외 산업폐기물의 각종오니 등을 경화시켜 무공해화 하므로서 건축자재, 토목공사자재, 농로, 농수로, 방조제등으로 이용가능케하는 산업 폐기물 및 토양혼합물을 경화제에 의하여 경화하는 방법에 관한 것이다.The present invention relates to a method of curing industrial wastes and soil mixtures that are inevitably generated in the modern industrial development process. Industrial wastes and soils that can be used as building materials, civil engineering materials, farm roads, agricultural waterways, and embankments by hardening the sludge, stone processing sludge, sea and stream bottoms, iron sludge, and other industrial waste sludge. A method for curing a mixture with a curing agent.

본 발명은 근대 산업의 급진적인 발전과정에서 발생하는 산업폐기물에 의한 각종공해를 해소하고 토목공사의 매립 또는 축조자재나 건축공사에 소요되는 각종 석재의 채석등으로 야기되는 자연회손을 줄임과 동시에 각종폐기물을 경화에 의해 산업에 이용하므로서 폐기물 재활용에 목적이 있다 하겠다.The present invention solves various pollutions caused by industrial waste generated during the radical development of the modern industry, reduces natural damage caused by landfilling of civil engineering works or quarrying of various stone materials for building construction and construction work. It is intended to recycle wastes by using them in industry by curing.

종래 토양이나 산업폐기물은 경화하는 방법으로서 사용되어온 경화제로 가장 일반적인 것이 시멘트, 회등이 있고 토양경화제로서 나트륨, 칼리움, 마그네슘, 칼슘 등의 염화물이 주종을 이루고 특히 연약지반이나 불량토질에 실리카 및 알루미나계의 고화제나 소석회 등을 사용하여 경화하는 방법을 사용하여 왔으나, 이는 토양의 일부성분 경화에 국한되었다.Conventional soil or industrial waste is a hardening agent that has been used as a hardening method. The most common ones are cement and ash, and chlorides such as sodium, kalium, magnesium, and calcium are mainly used as soil hardeners. Especially, silica and alumina are used on soft ground or poor soil. It has been used to harden the system using hardeners, slaked lime, etc., but it is limited to the hardening of some components of the soil.

본 발명에 의한 경화방법은 종래 특정성분에만 국한되는 경화제 성분에서 산업폐기물 및 토양혼합물을 동시에 경화시킬 수 있는 조성물과 시멘트를 적게 사용할 수 있는 조성방법으로 그 경화방법과 조성물의 조성비는 다음과 같다The curing method according to the present invention is a composition method capable of simultaneously curing industrial wastes and soil mixtures in a curing agent component limited to a specific component and using less cement.

산업폐기물 및 토양혼합물의 경화제 조성물Hardener Composition of Industrial Waste and Soil Mixtures

상기 경화제 조성물로 산업폐기물 및 토양혼합물을 경화하는 방법은 산업폐기물 및 토양혼합물 78-90%에 시멘트 11-15%을 균일하게 배합한 다음 상기 경화제조성물 2-4%을 수용액에 첨가하여 경화하는 방법이라 할수 있다.The method of curing the industrial waste and soil mixture with the hardener composition is a method of uniformly mixing 11-15% of cement with 78-90% of industrial waste and soil mixture, and then adding 2-4% of the hardening composition to an aqueous solution to harden it. This can be called.

여기에서 토양이라 함은 산토, 해성토, 점토 등을 들 수 있으며, 산업폐기물이라 함은 프라이애쉬, 폐주물사, 각종석재가공후의 분말, 소석고, 폐석고 각종 광물의 선광후 폐기되는 슬럿지, 용광로에서 발생되는 슬래그 등을 포함하는 광범위한 산업폐기물이다.Here, the soil may be a soil, marine soil, clay, etc., industrial waste is frying ash, waste foundry sand, powder after processing various stones, gypsum, waste gypsum, slag that is disposed after beneficiation of various minerals, slag generated in the furnace It is a wide range of industrial waste, including.

이와같은 토야이나 산업폐기물을 경화시키는 경화제 조성물은 수용액 상태로 사용하는데 경화제 조성물중 탄산나트륨, 염화가리, 규산화가리(X2SiO2), 황산철(FeSO4)등은 물에 작용해되고 탄산마그네슘은 염화암모늄 존재하에서 물에 용해되며 실리카겔은 수화되면서 분산제로 작용하여 산화티탄을 수용액에 잘 분산시킨다.The curing agent composition for curing such soil or industrial waste is used in the form of an aqueous solution. Among the curing agent composition, sodium carbonate, copper chloride, copper silicate (X 2 SiO 2 ), iron sulfate (FeSO 4 ), etc. act on water and magnesium carbonate It is dissolved in water in the presence of ammonium chloride, and silica gel hydrates and acts as a dispersant to disperse titanium oxide well in aqueous solution.

상기 조성물의 각각의 기능 및 작용은 탄산나트륨이 팽윤하는 진흙의 입자를 결속시켜 응고 시키는 작용을 갖이고 있고 염화가리는 폐기물이나 흙 입자의 응결을 촉진시키며 탄산마그네슘은 염화암모늄에 용해되면서 수경성과 응고성을 갖이면서 토양 또는 산업폐기물을 경화시킨다. 또 칼리움실리케이트(K2SiO2)는 무기물질에 대하여 강력한 접착력을 가지므로서 토양이나 산업폐기물의 입자와 입자를 강력하게 접착시키며, 실리카겔은 흙과 산업폐기물에 시멘트를 첨가하여 경화시키는 과정에서 특히 뻘과 같은 불량토질을 사용할 경우 토입자 표면에는 부착수가 있으며 부착수에는 휴민산계의 부식물이 다량 용해되어 있고 이와같은 부착수가 토입자를 강력하게 애워 쌓고 있어 흙이나 산업폐기물의 입자가 직접적으로 시멘트와 경화하는 것을 방해하고 있기 때문에 실리카겔의 수화반응에 의하여 용이하게 입자가 시멘트와 경화할 수 있게 하고, 한편 수화반응을 일으키므로서 불용성 경화생성물을 생성시켜 포졸란을 일으킨다. 그밖에 유화철은 불량토양을 안정화 시키므로서 경화를 도울 수 있다.Each function and action of the composition has a function of binding and solidifying the particles of the swelling mud of sodium carbonate, and the chlorinated chloride promotes the coagulation of waste or soil particles, and the magnesium carbonate dissolves in ammonium chloride, so that the hydraulic properties and solidification To harden soil or industrial waste. In addition, kalium silicate (K 2 SiO 2 ) has strong adhesion to inorganic materials and strongly bonds particles and particles of soil or industrial waste, and silica gel is hardened by adding cement to soil and industrial waste. Particularly, in case of using bad soil such as soil, it can be adhered to the surface of earth soil, and humic acid-based corrosives are dissolved in the surface of water. Due to the hindrance to curing, the particles can be easily cured with cement by the hydration reaction of silica gel. In addition, iron emulsion can help harden by stabilizing bad soils.

결국 토양 및 산업폐기물의 경화재 조성물의 전체적인 작용은 토양 및 산업폐기물 입자들을 경화하여 고화시키는 기능과 간접적으로 경화를 촉진시키거나 보조하는 기능이 있으며 첨가되는 시멘트의 경화작용을 촉진시키는 기능도 있고 상호입자를 강력하게 접착시키는 기능도 있으며 불량토양을 안정화 시키는 기능도 있다고 볼수 있다.After all, the overall action of the hardener composition of soil and industrial waste has the function of hardening and solidifying soil and industrial waste particles, and indirectly promoting or assisting hardening, and also promoting the hardening action of the added cement. It also has a strong adhesive function and stabilizes bad soils.

그밖에 본 발명은 토양 및 산업폐기물을 경화 고화하는 목적에 국환된 것만 아니고 이를 재활용하는 차원에서 주로 벽돌, 보도블럭, 기와 농로 및 농로포장, 구조물등으로 제품화하므로 강도, 방수성, 내수성, 내후성, 내약품성 등의 이에 맞는 물성도 충분히 고려된 방법이라 하겠다.In addition, the present invention is not limited to the purpose of hardening and solidifying the soil and industrial waste, and in order to recycle it, it is mainly manufactured into bricks, sidewalk blocks, tile farms and farm road pavement, structures, etc., so that strength, water resistance, water resistance, weather resistance, chemical resistance, etc. Physical properties such as this are also considered sufficiently.

특히 산업폐기물과 흙 혼합물을 경화시키는 과정에서 흙과 산업폐기물의 배합비는 흙의 종류나 산업폐기물의 종류에 따라서 약간의 차이는 있지만 흙 30-70%, 산업폐기물 70-30%의 배합비 범위내에서 가능하고 좋기로는 1:1의 비율이 바람직하며 흙과 산업폐기물의 자연 함수비는 35% 미만이어야 하고 경화제 조성물의 수용액은 전조성물의 포화수용액 이상의 물을 사용하는 것이 작업성이 좋고, 흙과 산업폐기물의 자연함수비 35%와 합하여 전체중량비의 65%를 초과하지 않는 것이 바람직하다. 그 이유로는 수분함량이 65% 이상인 경우에는 경화 속도가 늦어지며 더욱 수분함량이 많을 경우에는 경화가 잘 일어나지 않는다.In particular, the mixing ratio of soil and industrial waste in the process of curing industrial waste and soil mixture is slightly different depending on the type of soil or industrial waste, but within the range of 30-70% soil and 70-30% industrial waste. The ratio of 1: 1 is preferably as good as possible, and the natural water content of soil and industrial waste should be less than 35%, and the aqueous solution of the curing agent composition is more workable than the saturated aqueous solution of the precursor composition. It is desirable not to exceed 65% of the total weight ratio in combination with the 35% natural function ratio of the waste. For this reason, when the moisture content is 65% or more, the curing rate is slow, and when the moisture content is more, the curing hardly occurs.

본 발명에 의한 경화제 조성물의 작용과 효과를 측정하기 위하여 아래와 같이 실시예로 나타내었다.In order to measure the action and effect of the curing agent composition according to the present invention is shown in the following examples.

(실시예1)Example 1

마사토 430kg, 슬렐트가공오니 300kg, 폐석고 130kg을 충분히 혼합한 혼합물에 시멘트 130kg을 첨가 균일하게 혼합하여 여기에 경화제 조성물 3kg을 물에 용해한 수용액을 첨가하여 충분히 교반하고 그 교반물로 벽돌을 성형하여 5일 경과 후 물성을 측정한 결과 아래와 같은 시험성적표를 얻을 수 있었다.Add 130 kg of cement to the mixture of Masato 430 kg, slatted sludge 300 kg, and 130 kg of waste gypsum, and then mix it uniformly. As a result of measuring the physical properties after one day, the following test results were obtained.
