Description
본 발명은 천연 세라믹이 포함된 원료를 주성분으로 하는 천연토, 고화제 및 재활용 순환골재 등의 자연 친화적이고 저비용의 요소를 사용하면서도 고강도 특성을 갖는 흙 블록을 제조하기 위한 흙 블록용 조성물에 관한 것이다.
The present invention relates to a soil block composition for producing a soil block having high strength properties while using nature-friendly and low-cost elements such as natural soil, solidifying agent, recycled aggregate and the like containing a raw material containing natural ceramics as a main component .
일반적으로 블록은 하천변이나 강변은 물론 도로변 등의 각종 경사면에 축조되어 토사가 유실되거나 붕괴 되는 것을 방지하기 위하여 설치되는 구조를 이루는 것이나, 현재 사용되고 있는 다양한 유형의 블록 류들은 그 소재의 한계로 인해 식물의 자생환경이 주어지지 않음은 물론 환경 오염의 문제점이 되고 있다.Generally, a block is constructed in various slopes such as a river side, a river side, and a roadside side to prevent the loss or the collapse of the soil, but various types of block types currently used are limited to the plants And it is a problem of environmental pollution.
즉, 종래의 다양한 유형의 블록 류들은 그 소재가 시멘트를 주재료로 사용하여 시멘트의 강한 독성이 주변환경을 오염시킬 뿐만 아니라 시멘트 성분이 수분을 포함한 흙보다 더 많은 태양열을 흡수, 저장으로 인한 열섬현상으로 시멘트를 주재료로 하는 블록 축조물의 주변온도가 상승하여 2차오염의 문제점이 되었다.In other words, the conventional various types of blocks have a problem that the strong toxicity of the cement causes the surrounding environment to be contaminated by using the cement as the main material, and the cement component absorbs more heat than the soil containing moisture, As a result, the ambient temperature of the cement-based block was increased, causing secondary contamination.
또한 시멘트를 주재료로 하는 블록들의 축조 후 축조물이 주변환경을 차단시켜 설치지역의 식생물이 생존할 수 없는 등의 생태계 환경을 악화시키는 요인이 되었다.In addition, after building blocks made of cement as a main material, it has become a factor to deteriorate the ecosystem environment such as that the food is not able to survive in the installation area by blocking the surrounding environment.
아울러 시멘트를 주재료로 하는 축조된 블록들은 폐기시 자연으로의 흡수가 불가능하여 물리적, 화학적 조작에 의하여 감량화, 무해화 등의 일련의 폐기처리 공정을 하는 과정에서 막대한 비용손실이 발생하는 문제점이 있었다.
In addition, the blocks built with cement as a main material are not absorbed into nature at the time of disposal, so that there is a problem of massive cost loss in a series of disposal processes such as weight reduction and detoxification by physical and chemical operations.
본 발명은 상기 문제점을 해소하고자 안출한 것으로서, 본 발명의 목적은 천연 세라믹이 포함된 원료를 주성분으로 하는 천연토, 고화제 및 재활용 순환골재 등의 자연 친화적이고 저비용의 요소를 사용하면서도 고강도 및 2차적인 폐기물이 발생되지 않는 흙 블록용 조성물을 제공하는데 있다.

The chemical composition is shown in the following Table 2, Lt; / RTI >
본 발명을 구성하는 무기물 고화제는 조성물을 고화시키는 고로슬래그 미분말 50 ~ 60중량%, 소석회 15 ~ 25중량%, 실리카흄 1 ~ 3중량%, 무수석고 20 ~ 30중량%로 구성되며, 천연토와 바텀애쉬를 포함한 총중량 대비 분말 형태로서 15 ~ 25중량%를 혼합하는 것이 바람직하다.The inorganic solidifying agent constituting the present invention is composed of 50 to 60 wt% of blast furnace slag to solidify the composition, 15 to 25 wt% of slaked lime, 1 to 3 wt% of silica fume and 20 to 30 wt% of anhydrous gypsum, It is preferable to mix 15 to 25% by weight in powder form with respect to the total weight including bottom ash.
또한 본 발명의 다른 실시예에서 고화제를 이루는 성분 중 실리카흄을 대체하는 요소인 플라이 애쉬(fly ash)를 사용하여, 즉 무기물 고화제를 고로슬래그 미분말 50 ~ 60중량%, 소석회15 ~ 25중량%, 플라이 애쉬(fly ash) 1~3중량%, 무수석고 20 ~ 30 중량%를 혼합하여도 본 발명의 실시가 가능하다.In another embodiment of the present invention, fly ash, which is an element replacing silica fume, is used as a component of the solidifying agent, that is, an inorganic solidifying agent is mixed with 50 to 60 wt% of blast furnace slag, 15 to 25 wt% 1 to 3% by weight of fly ash, and 20 to 30% by weight of anhydrous gypsum.
고화제는 적정 비율로 배합설계를 하게 되면 천연토와 석회,석고의 이온 응집반응 및 포졸란 반응 및 고로슬래그의 잠재수경성 반응을 통해 천연토를 소성하지 않고 소정의 강도를 확보할 수 있으며, 천연 무기질 첨가제를 첨가하게 되면 물에 의한 풀림 현상이나 표면에 뭍어나는 현상도 방지할 수 있다. The solidifying agent can ensure the predetermined strength without burning the natural soil through the ion agglomeration reaction and the pozzolanic reaction of the natural soil, the lime and the gypsum, and the latent hydraulic reaction of the blast furnace slag, Addition of additives prevents water loosening or surface sticking.
또한 위와 같이 제조된 무기물 고화제는 성분중 다량의 에트링가이트(Ettringite)가 생성되는데 이것의 화학성분은 3CaO Al2O3 3CaSO4 32H2O 이며 이 성분은 다량의 물을 결합수로서 취하여 반응을 촉진시키는 동시에 흙입자의 이동을 제어하는 역할을 하게 되어 고화를 용이하게 하는 작용을 하며 산화칼슘, 수산화칼슘에 의하여 수화물이 생성되어 흙입자의 고화를 더욱 상승시키게 되며 흙입자에 포함되어 있는 SiO2, Al2O3 등의 성분이 수산화칼슘과 수화물을 생성하여 포졸란을 활성화시켜 경화를 촉진시키게 된다.In addition, a large amount of Ettringite is produced in the inorganic solidifying agent, and the chemical component thereof is 3CaO Al 2 O 3 3CaSO 4 32H 2 O, which is obtained by taking a large amount of water as the bonding water, And also acts to control the movement of the soil particles, thereby facilitating the solidification. The hydrates are generated by calcium oxide and calcium hydroxide to further increase the solidification of the soil particles, and the SiO 2 , Al 2 O 3 And the like, generate calcium hydroxide and hydrate, thereby activating the pozzolan to promote curing.
본 발명에 사용되는 고로슬래그 미분말은 용광로에서 선철과 함께 생성되는 용융스래그를 급랭시켜 얻은 입상의 수쇄슬래그를 건조 및 분쇄하여 미분화한 것으로 잠재수경성이 있다.The blast furnace slag fine powder used in the present invention is obtained by pulverizing and crushing the granulated water-chain slag obtained by quenching the molten slag produced together with the pig iron in the furnace, and is potentially hydraulic.
고로슬래그의 반응성은 일반적으로 염기도 및 유리화율이 높을수록 크며 비중은 2.92 ~ 2.95 범위이며 분말도는 비표면적으로 4000 ~ 6000㎠/g이 적당하다.The reactivity of the blast furnace slag is generally higher as the basicity and vitrification ratio are higher, the specific gravity is in the range of 2.92 to 2.95, and the specific gravity of the blast furnace slag is 4000 to 6000 cm 2 / g.
고로슬래그 분말을 사용함에 따라 표면 활성도가 증가하며 Al2O3 의 용출속도가 빨라지게 되어 에트링가이트의 생성이 촉진되며 또한 C-S-H계 수화물의 겔화를 촉진시키는 것과 동시에 미 반응 부분을 감소시키는 효과가 있으며, 화학적 조성은 다음의 표 4와 같다.As the blast furnace slag powder is used, the surface activity is increased and the elution rate of Al 2 O 3 is accelerated, thereby promoting the production of ettringite and promoting the gelation of CSH-based hydrate and reducing the unreacted portion The chemical composition is shown in Table 4 below.
본 발명에 사용되는 소석회는 일반 시중에서 판매되는 백색 분말상태로서 CaO 함량이 70% 이상의 공업용이며, 입도는 200mesh 90%이상의 것으로, 천연토 분말을 단결화를 통해 강도를 향상시키고 잠재수경성을 촉진시키는 자극제로서 이온 응집반응 및 포졸란 반응이 충분히 수행될 수 있도록 첨가한다.The slaked lime used in the present invention has a CaO content of 70% or more for industrial use and a particle size of 200 mesh or more of 90% or more as a white powder sold in the market. As an irritant, an ion flocculation reaction and a pozzolanic reaction are added so that they can be sufficiently performed.
소석회는 고로슬래그의 수화반응에 필요한 알카리성 부여하는 자극제로서 소량첨가하여도 수분과의 접촉에서 생성되는 내부 입자 막을 빠른속도로 파괴할 수 있으므로 수화반응의 가속화에 따른 초기 압축강도는 증가되며, 화학적 조성은 다음의 표 5와 같다.The slaked lime is a stimulant for alkaline imparting necessary for the hydration reaction of the blast furnace slag, and even when added in small amounts, the internal particle film formed by contact with moisture can be destroyed at high speed, so that the initial compression strength due to the acceleration of the hydration reaction is increased, Are shown in Table 5 below.
본 발명에 사용되는 실리카흄(silica fume)은 회색의 균질한 실리케이트 물질로서 실리콘합금 제조시 2차 제품으로 발생하며, 실리카흄의 입자 크기는 45㎛이하이며, 초미분 입자에 의한 충진효과에 따른 조성물의 내구성 증대와 수화에 의한 포졸란 반응으로 강도 증진 등의 효과가 있으며, 화학적 조성은 다음의 표 6과 같다.The silica fume used in the present invention is a gray homogeneous silicate material, which is generated as a secondary product in the production of a silicon alloy. The silica fume has a particle size of 45 μm or less, The durability and the pozzolan reaction caused by hydration have the effect of improving the strength and the chemical composition is shown in Table 6 below.
본 발명에 사용되는 무수석고는 일반적으로 사용되는 있는 석고로서 슬래그와 소석회에 혼합하여 물과 반응시키게 되면 에트링가이트(3CaO, Al2O3 , 3CaSO4 , 32H2O)가 수화반응을 일으키면서 감수(減水)효과 및 미세입자의 공극충진으로 조직이 치밀화 되므로 초기강도가 증가하며 수화가 촉진된다.The anhydrous gypsum used in the present invention is a generally used gypsum. When mixed with slag and slaked lime and reacted with water, the hydration reaction of ettringite (3CaO, Al 2 O 3, 3CaSO 4, 32H 2 O) The effect is enhanced by the densification of the tissue due to the filling of the microparticles with the voids, so that the initial strength is increased and hydration is promoted.
이처럼 본 발명은 장기강도를 증진시키는 고로 슬래그와 초기강도를 증진시키는 무수석고와 소석회을 적정비율로 배합하여 구성하므로서 상당한 강도 증진의 효과가 발생하는 것이며, 화학적 조성은 다음의 표 7과 같다.As described above, the present invention has a significant improvement in strength due to the blending of blast furnace slag for improving long-term strength, anhydrous gypsum for improving initial strength, and slaked lime at a proper ratio, and the chemical composition is as shown in Table 7 below.

It has 18 to 28% by weight of KCl, 5 to 10% by weight of MgCl 2 25 to 35% by weight of NaCl, 20 to 30% by weight of CaCl 2 1 to 7% by weight of Na 2 SO 4 The inorganic additive to be produced is added to a mixture of natural soil, bottom ash and solidifying agent in an amount of 1 to 3 wt% % By weight in the liquid form.
이와 같이 본 발명은 천연토와 고로슬래그, 소석회, 실리카흄, 무수석고 및 천연 무기질 첨가제를 소정의 중량비율로 혼합하면 친화력에 의해 흙입자의 표면에 흡착해 있던 Na+,K+, Mg2 + 등이 석회의 칼슘이온(Ca2+)으로 치환되어 석회에 흙입자가 서로 접근하여 결합되는 이온 응집반응에 의해 고화가 진행된다.As described above, when Na 2 +, K +, Mg 2 +, or the like adsorbed on the surface of the soil particles due to affinity is mixed with the lime of the clay by mixing the natural soil with the blast furnace slag, the slaked lime, the silica fume, (Ca 2+ ), and solidification proceeds by the ion agglutination reaction in which the earth particles are bonded to each other by lime.

In addition, in the mixing design of Example 1, the inorganic additive was mixed by 2 wt% of the mixture weight with 30 wt% of natural soot, 50 wt% of bottom ash and 20 wt% of solidifying agent, Table 9 shows the effect of the naturally dried molded product after curing at a curing temperature of 60 ° C for 12 hours under 150㎏f / ㎠ pressure on curing time, compressive strength and water absorption according to molding pressure.
위의 (표 9)에 도시된 바와같이 천연토 30중량%, 바텀애쉬 50중량%, 고화제 20중량%로 혼합된 혼합물에 혼합물 중량의 2중량% 만큼 무기질 첨가제를 혼합한 성형품을 양생 시간대별 물성시험에는 성형압력을 150㎏f/㎠로 고정 시킨 후 압축강도 및 흡수율을 측정 하였으며, 반면에 성형 압력별 물성시험에는 양생시간을 12시간 동안 60℃로 고정시킨 후 압축강도 및 흡수율을 측정하였다.As shown in Table 9 above, a molded article obtained by mixing 2% by weight of the mixture by weight of the mixture with 30% by weight of natural soil, 50% by weight of bottom ash and 20% by weight of a solidifying agent, In the physical property test, the compression strength and the water absorption rate were measured after fixing the molding pressure at 150 kgf / ㎠, while the curing time was fixed at 60 ° C for 12 hours in the physical properties test by molding pressure, .
본 발명의 성형품을 양생 시간대별로 측정한 결과 4 ~ 8시간대가 압축강도 및 흡수율이 미흡하게 나왔으나, 12 ~ 24시간대에는 압축강도나 흡수율이 양호하게 나타 났으며, 또한 성형 압력별로 측정한 결과 50 ~ 100㎏f/㎠대가 압축강도 및 흡수율이 미흡하게 나왔으며, 150 ~ 300㎏f/㎠대에는 압축강도나 흡수율이 양호하게 나타났으나, 200㎏f/㎠ 이상 성형압을 가했을때는 오히려 상부 금형틀에 원료가 달라붙는 현상이 발생하여 150㎏f/㎠ 정도의 성형압이 적당한 것으로 판단된다.As a result of measuring the molded article according to the present invention at the curing time, the compressive strength and the water absorptivity were inadequate for 4 to 8 hours, but the compressive strength and the water absorption rate were good at 12 to 24 hours. The compressive strength and the water absorption rate were inadequate at 150kgf / cm2 to 100kgf / cm2, and the compressive strength and the water absorption rate were satisfactory at 150kgf / cm2 to 150kgf / cm2. However, It is considered that the molding pressure of about 150 kgf / ㎠ is suitable because the raw material sticks to the mold frame.
결론적으로 천연토 30중량%, 바텀애쉬 50중량%, 고화제 20중량%로 혼합된 혼합물에 혼합물 중량의 2중량% 만큼 무기질 첨가제를 혼합한 성형품의 최소 양생시간이 12시간 정도이고, 성형압력은 150㎏f/㎠ 정도로 나타났는데 이는 최적의 경제성 및 생산성이 높은 결과를 나타내었다.As a result, the minimum curing time of a molded article obtained by mixing an inorganic additive by 2 wt% of the mixture weight with a mixture of 30 wt% of natural soil, 50 wt% of bottom ash, and 20 wt% of a solidifying agent is about 12 hours, 150kgf / ㎠, which is the most economical and productive.
또한 중금속 용출시험를 한국건설생활환경시험연구원장에 의뢰하여 시행하였으며, 시험방법은 폐기물 공정시험 기준에 의해 시행 하였고, 시험결과 독성이 없는 것으로 알 수 있으며, 그 결과는 다음의 표 10과 같다.In addition, the heavy metal leaching test was commissioned to the head of the Korea Institute of Construction & Living Environment Test. The test method was carried out according to the waste process test standard, and the test results were found to be non-toxic.
