Description

본 발명은 시멘트를 사용하지 않는 친환경 투수콘크리트 기술로 고로슬래그와 알칼리자극제(NaOH, Ca(OH)2, KOH 등)를 혼합하여 AAS(Alkali Activation Slag) 반응을 유도함으로써 친환경적인 비소성시멘트 기술을 진행하며, 우수 등의 정화성능을 향상시키고자 흡착성능이 우수한 일라이트와 기능성 혼화재(Anatase형 TiO2, 합성 Zeolite 등)를 포함하여 타설함으로써 도시 사막화 및 우수 정화가 가능한 비차도용 투수콘크리트 기술 분야에 속한다.
The present invention relates to an eco-friendly waterproof concrete technique that does not use cement, and it is possible to mix the blast furnace slag with an alkali stimulant (NaOH, Ca (OH) 2, KOH, And it is in the field of non-permeable waterproofing concrete technology that can be deserted and cleaned up in the city by installing ilwite with excellent adsorption performance and improving the purification performance of storm water, including functional admixture (Anatase type TiO2, synthetic zeolite, etc.) .

온실가스 감축은 국제적인 감축 목표에 대한 합의점을 새롭게 도출하고, 각 국가는 국가적인 차원에서 배출저감 의무를 이행할 것으로 전망되는데, 이러한 환경의 문제가 발생되는 분야를 크게 산업, 교통 및 건설로 분류할 때, 이 중에서도 건설분야는 전체 산업 분야 CO2 배출량의 약 38%를 차지하는 것으로 알려져 있는 만큼 지구환경과 인간의 건강복지에 미치는 영향과 파급효과가 큰 분야라고 할 수 있다. 현재 과학기술의 발달과 경제성장은 건축재료의 분야에도 신재료의 개발 및 성능향상을 요구하고 있다. Greenhouse gas reductions are expected to bring new consensus on international reduction targets, and each country will be expected to fulfill its emission reduction obligations at the national level. The areas where such environmental problems arise are largely classified as industrial, transportation and construction The construction sector is known to occupy about 38% of the total industrial CO2 emissions. Therefore, it can be said that the impact on the global environment and human health and welfare is significant. At present, the development of science and technology and the economic growth require the development of new materials and the improvement of performance in the field of building materials.

WTO와 국내 건설시장의 개방에 따른 건축재료의 원가절감과 품질향상에 대한 요구도 가중되고 있는 실정이다. 그 해결책으로 대두되는 기술이 바로 비소성시멘트 기술이며, 여기서 비소성 시멘트란 클링커 무함유 비소성 시멘트(Non-Sintered Cement, 이하 NSC)를 지칭하는 것으로 크게 점토질 광물과 알칼리의 반응을 이용한 지오폴리머(Geo-polymer) 분야와 잠재수경성 물질인 고로슬래그 미분말(Granulated Blast Furnace Slag, 이하 GBFS)을 알칼리로 자극하여 수경성 경화체를 제조하는 알칼리 활성화 슬래그(Alkali Activated Slag, 이하 AAS) 분야로 구분된다. 그동안 시멘트의 원료 및 콘크리트 혼화재료로 일부 사용되었던 고로슬래그는 제철과정 중 산출되는 부산물로써 생산과정 중 클링커의 소성과정이 필요없기 때문에 환경문제의 부담을 줄일 수 있을 뿐만 아니라 원가절감 측면에 있어서도 기존의 포틀랜드 시멘트와 비교하였을 때 훨씬 더 유리하다고 할 수 있다.The demand for cost reduction and quality improvement of building materials due to opening of WTO and domestic construction market is also increasing. The non-sintered cement refers to non-sintered cement (NSC) which is mainly composed of clay minerals and alkali. (AAS), which produces hydraulically cured products by stimulating with alkali the granulated blast furnace slag (GBFS), which is a latent hydraulic material, and an alkaline activated slag (AAS). Blast furnace slag, which has been used as raw material and concrete admixture for cement in the past, is a by-product produced during the steel making process and it does not require burning process of clinker during production process. Therefore, it can reduce the burden of environmental problems, It is much more advantageous when compared to Portland cement.

고로슬래그는 물과 접촉하면 입자 표면에 불투성 산성피막으로 인해 경화가 이루어지지 않는다. 이때 반응을 유도하기 위해 강알칼리에 의한 자극제의 역할이 필요하다. 한편 기존의 비소성 시멘트 기술은 대부분 고가의 고미분말 혼화재를 사용하며, 고가의 알칼리 자극제를 대량 사용함에 따라 경제성이 부족하며, 고로슬래그 미분말을 사용할 경우 잠재수경성 특성에 의해 초기 강도 확보가 힘들다는 문제점이 있다.          When blast furnace slag is in contact with water, it hardens due to the opacifying acid film on the particle surface. At this time, the role of stimulant by strong alkali is needed to induce the reaction. On the other hand, most of the conventional non-sintered cement technology uses high-priced fine powder admixture and it is not economical due to use of expensive alkali stimulant in large quantity. When using blast furnace slag fine powder, it is difficult to secure initial strength by potential hydraulic characteristics .

관련특허문헌 공개번호 10-2012-0078273(출원일: 2010년 12월 31일)을 참조하면, 고로슬래그에 나노기술을 도입하여 나노슬래그와 알칼리 자극제를 사용하여 비소성 시멘트 모르타르를 제조함으로써 소성 시멘트 모르타르에 비하여 이산화탄소의 배출량을 감소시키는 것과 함께 비소성 시멘트 모르타르를 제조하기 위하여 사용되는 알칼리 자극제의 함량을 감소시킬 수 있고 이러한 알칼리 자극제의 사용함량의 감소로 인하여 제조원가를 절감시킬 수 있고, 환경적으로도 유용한 비소성 시멘트 모르타르를 제공할 수 있다고 제시되어 있다.
Referring to the related patent publication No. 10-2012-0078273 (filed on December 31, 2010), nano-technology is introduced into blast furnace slag to produce non-fired cement mortar using nano slag and alkali stimulant, The amount of the alkali stimulant used for producing the non-fired cement mortar can be reduced, and the production cost can be reduced due to the reduction of the use amount of the alkali stimulant. In addition, It has been suggested that useful non-fired cement mortar can be provided.

그러나 우수 정화성능을 개선하기 위한 물질의 포함이 결여되어 있는데 착안하여 본 발명에서는 일라이트와 기능성 혼화재를 함께 타설함으로써 흡착성능이 탁월한 비소성 투수콘크리트를 제시하고자 한다.However, since the inclusion of a material for improving the excellent purification performance is lacking, the present invention proposes a non-calcined permeable concrete excellent in the adsorption performance by placing the ilite and the functional admixture together.

도 1은 일라이트의 구조 형상을 도식화 한 것이다.Fig. 1 schematically illustrates the structure of a light.

상기 목적을 달성하기 위하여, 본 발명은 고로슬래그 20~30%, 물 10~15% , 알칼리자극제 2~5%, 굵은골재 40~60%, 일라이트 3~5%, 제올라이트 1~2%, 이산화티탄 1~3%을 포함한다. 위의 재료 중 굵은골재는 먼저 타설하여 다짐을 진행하고 나머지 재료는 교반하여 부어넣기 함으로써 공극률을 유지하는 것이 바람직하다.
In order to achieve the above object, the present invention provides a method for producing a steel slag comprising 20 to 30% of blast furnace slag, 10 to 15% of water, 2 to 5% of alkali irritant, 40 to 60% of coarse aggregate, 3-5% of ailite, And 1 to 3% of titanium dioxide. It is preferable that the coarse aggregate among the above materials is poured first and then the compaction is proceeded, and the remaining material is stirred and poured to maintain the porosity.

또한 골재는 20mm이하의 골재로 보행에 무리가 없도록 충분히 사전 다짐하는 것이 바람직하며, 고로슬래그와 알칼리자극제 및 일라이트를 포함한 기능성혼화재 조성물은 한곳에 타설 후 펴 바르는 것 보다는 분산하여 타설하는 것이 바람직하다.
Also, it is preferable that the aggregate is preliminarily compacted so that there is no problem in walking with aggregates of 20 mm or less, and it is preferable that the functional admixture composition including blast furnace slag, alkali stimulant and ilite is dispersed and laid rather than spreading it in one place.

일라이트은 이질 퇴적암, 열서변질대 및 중성-산성암의 풍화물에서 매우 흔한 2차 광물이며 K+가 풍부한 환경에서 잘 형성되는데, 장석이나 운모류로부터 쉽게 형성되기도며 열수용액으로부터 직접 침전되기도 한다. 일라이트은 셰일이나 사암에서 카올리나이트, 일라이트-스멕타이트 혼합층 상광물과 더불어 가장 풍부한 점토 광물이다.        Illight is a very common secondary minerals in heterogeneous sedimentary rocks, open-ended alterations and neutral-acidic rocks and is well formed in K + -rich environments, which can be easily formed from feldspar or mica and precipitated directly from the thermal aqueous solution. Illyite is the most abundant clay minerals in shale and sandstone, along with kaolinite and ilite-smectite mixed-bed minerals.

특히 일라이트은 저온환경에서 스멕타이트로부터 흔히 형성되기 때문에 일라이트 질 점토는 스멕타이트 층과 일라이트 층이 c축 방향을 따라서 규칙적으로 혼합된 복잡한 구조를 보이기도 한다. 이 경우 일라이트-스멕타이트의 혼합층상광물, 또는 혼합층상구조라고 부른다. 일반적인 퇴적환경에서는 속성작용이 진행됨에 따라 점토광물은 스멕타이트로부터 시작하여 I/S혼합층상광물을 거쳐, 최종적으로는 일라이트으로 전이한다. 이같은 전이는 K+의 공급과 반응온도와 밀접한 관련성을 가진다. 특히 I/S혼합층상광물의 특성은 스멕타이트와 더불어 일라이트과 밀접히 관련되기 때문에 점토광물 중에서 아마도 일라이트만큼 오랜 기간동안 주목과 놈쟁의 대상이 되어온 광물도 드물다.        Especially, Illight is frequently formed from smectite in low temperature environment. Therefore, Illite clay has a complicated structure in which Smectite layer and Illite layer are regularly mixed along c axis direction. In this case, it is called a mixed layered mineral of ilite-smectite, or a mixed layered structure. In the general sedimentation environment, clay minerals start from smectite, I / S mixed layer minerals, and ultimately migrate to ilite as property proceeds. This transition is closely related to the K + supply and reaction temperature. In particular, the characteristics of I / S mixed bedded minerals are closely related to ilite along with smectite, so rarely among the clay minerals, which have been subjected to asymmetric attention for a long time as illite.

특히 일라이트의 결정도는 속성작용 단계를 해석함에 있어서 매우 중요한 근거로 이용되고 있다. 또한 이를 이용하여 온도를 추정하기도 한다. 특히 지표 및 저온환경에서 형성되는 점토광물은 온도가 높아질수록 보다 안정한 형태로 전이 하면서, 결정의 성장이 일어난다.        Especially, the crystallinity of Illight is used as a very important basis in interpreting the property action phase. It is also possible to estimate the temperature by using it. Particularly, the clay minerals formed at the surface of the earth and the low temperature environment transition to a more stable form as the temperature increases, and the crystal growth occurs.

일라이트을 비롯한 대부분의 점토 광물은 저온 환경에서 준안정적인 광물상으로 존재하기 때문에 열역학적 정보가 매우 제한되어 있으며, 화학조성 또한 치환관계가 복잡하고 다양하여 여러 종류의 고용체로 구성된다. 그러나 반대로 이러한 점을 잘 이해하면 점토광물의 물리 화학적인 특성을 유추할 수가 있으며, 지질학적 환경해석이나 산업 응용 분야에도 그 활용도가 높다.          Since most clay minerals including ilite exist as quasi-stable minerals in a low temperature environment, thermodynamic information is very limited, and the chemical composition is also complicated and varied in substitution relation and composed of various kinds of solid solutions. On the other hand, understanding this point can infer the physico-chemical characteristics of clay minerals, and is also applicable to geological environmental analysis and industrial applications.

일라이트의 결정도는 다양하며, 입자의 물리적 상태도 일정하지 않아 물리화학적인 특징을 일률적으로 적용하든지 규정하기에는 많은 무리가 따른다. 그 때문에 제대로 정립된 일라이트의 물리 화학적 변수를 문헌에서 찾기란 어려우며, 시험자마다 각 상황에 따라 직접 물성치를 측정하는 것이 바람직하다.
The crystallinity of ilite is variable, and the physical state of particles is not constant. Therefore, it is difficult to specify uniformly the physicochemical characteristics. For this reason, it is difficult to find the physicochemical parameters of the well-established Ilwright in the literature, and it is desirable to directly measure the physical properties according to each situation.
