Description

화강암 석분을 이용한 모르타르용 조성물{mortar composition using granite sludge}Mortar composition using granite stone powder {mortar composition using granite sludge}

본 발명은 도로 기저층, 자전거 도로, 벽돌, 보도 블록 등의 제조나 시공에 사용되는 모르타르용 조성물에 관한 것으로, 특히 화강암 채석장이나, 화강암의 가공 현장에서 발생하는 화강암 석분 슬러지를 탈수하여 첨가제 및 시멘트와 혼합함으로써 자원을 재활용할 수 있도록 하고, 만족할만한 구조적 성능을 발휘할 수 있도록 한, 화강암 석분을 이용한 모르타르용 조성물에 관한 것이다.The present invention relates to a composition for mortar used in the manufacture or construction of road base layers, bicycle roads, bricks, sidewalk blocks, etc. It relates to a composition for mortar using granite stone powder, which enables resources to be recycled by mixing and exhibits satisfactory structural performance.

화강암은 인위적으로 가공하려고 하면 비용이 상당히 많이 소요되지만 현재 화강암 석분슬러지는 사업장에서는 부지 확보하여 매립하는 것과 특별한 용도 아니면 별도의 사용처가 없기 때문에 분진으로 생성되는 집진 부산물로 남아도는 형편이다. Artificial processing of granite is costly, but currently, granite stone powder sludge remains as a by-product of dust collection because there is no place for reclamation after securing a site at the business site, or for a special purpose or a separate use.

이 분말을 미립분이기 때문에 대기중의 공기를 오염시키거나 수중에서 분상되어 물을 오염시키기도 한다.Since this powder is a fine powder, it pollutes the air in the atmosphere or pollutes water by being powdered in water.

이러한 화강암 석분을 재활용하기 위한 기술로, "화강암 석분 슬러지를 이용한 경량 기포 콘크리트"(한국 공개특허공보 제10-2002-0019680호, 특허문헌 1)에는 석분 슬러지와 시멘트를 일정 비율로 혼합한 경량 기포 콘크리트에 관한 기술이 공개되어 있다.As a technology for recycling such granite stone powder, "light aerated concrete using granite stone powder sludge" (Korean Patent Publication No. 10-2002-0019680, Patent Document 1) has a lightweight air bubble mixed with stone powder sludge and cement at a certain ratio The technology related to concrete has been disclosed.

상기한 특허문헌 1의 경우 시멘트가 적어도 50 중량% 이상 함유되어야 충분한 강도를 갖는 것으로 보고되고 있다.In the case of Patent Document 1 described above, it is reported that cement has sufficient strength only when it contains at least 50% by weight of cement.

또다른 기술로, "석분을 포함하는 콘크리트 조성물"(한국 등록특허공보 제10-0944190호, 특허문헌 2)에는 시멘트 100 중량부에 대해 석분 10 ~40 중량부의 미량을 사용하여 28일 경과 후 대략 20 N/㎟ 이상을 나타내는 결과가 나타나 있다.As another technique, in "Concrete composition containing stone powder" (Korean Patent Publication No. 10-0944190, Patent Document 2), a trace amount of 10 to 40 parts by weight of stone powder is used with respect to 100 parts by weight of cement, and after 28 days, approximately Results showing 20 N/mm 2 or more are shown.

또다른 기술로, "폐석가루의 재활용 방법 및 콘크리트 제품"(한국 공개특허공보 제10-2003-0090295호, 특허문헌 3)에 대략 시멘트를 11 ~13 중량%를 기준으로 한 가운데 폐석가루를 15, 20 중량% 함유하도록 하고, 모래, 자갈 등을 다량 포함시켜 제조한 콘크리트 제품의 강도가 적정 수준으로 보고된 사례가 공개되어 있다.As another technology, in "Method for recycling waste rock powder and concrete products" (Korean Patent Publication No. 10-2003-0090295, Patent Document 3), about 11 to 13% by weight of cement is used, and waste stone powder is 15 , 20% by weight, and a case in which the strength of a concrete product manufactured by including a large amount of sand, gravel, etc. is reported at an appropriate level has been disclosed.

상기한 특허문헌 1 내지 3을 살펴보면, 시멘트가 과반이 넘는 양이 포함되도록 하거나, 석분 외에 다량의 모래와 자갈을 포함시켜 충분한 강도가 나오도록 한 것으로 나타났다.Looking at Patent Documents 1 to 3 above, it was found that sufficient strength was achieved by including more than half of cement or by including a large amount of sand and gravel in addition to stone powder.

이러한 점을 해결하기 위한 방안으로 60℃ 이상의 고온 조건에서 가압을 하면서 8시간 이상 유지하는 방안도 있으나, 이 경우 비경제적인 이유로 외면받고 있는 실정이다.As a way to solve this problem, there is also a way to maintain it for 8 hours or more while pressurizing at a high temperature of 60 ° C. or higher, but in this case, it is ignored for uneconomical reasons.

한편, 시멘트는 산업의 근대화 과정에서 가장 중요하고 널리 사용되어 온 건설용 구조재료로서 도로, 교량, 터널, 항만, 주택, 건물 등 각종 사회간접자본(SOC)의 건설에 있어 기본이 되는 재료이다.On the other hand, cement is the most important and widely used structural material for construction in the process of industrial modernization, and is a basic material for the construction of various social overhead capital (SOC) such as roads, bridges, tunnels, ports, houses, and buildings.

특히 20세기에 들어서 산업구조의 고도화에 따른 건설기술도 진보해왔으며, 이에 맞추어 20세기 초부터 본격적으로 생산되기 시작한 보통 포틀랜드시멘트는 그 생산량도 크게 증가하여 현재 15억 톤 정도를 생산하고 있으며, 이용기술도 획기적으로 발전하여 왔다.In particular, in the 20th century, construction technology has also advanced according to the advancement of the industrial structure, and in line with this, the production of ordinary Portland cement, which began to be produced in earnest from the beginning of the 20th century, has increased significantly and currently produces about 1.5 billion tons. Technology has also developed dramatically.

그리고 향후에도 SOC의 확충을 위해 초고층건물, 심도 지하구조물, 거대교량, 해상공항 및 수중 도시 등 건설 프로젝트가 계획되는 등 시멘트의 수요는 꾸준히 증가할 것으로 예측된다.And in the future, the demand for cement is expected to steadily increase as construction projects such as high-rise buildings, deep underground structures, giant bridges, sea airports, and underwater cities are planned for the expansion of SOC.

이와 같이 시멘트는 그 동안 SOC 건설에 중요한 역할을 해왔음에도 불구하고 최근 들어 자연 및 지구환경에 대한 부정적인 재료로 인식되는 경향이 높아지고 있다.As such, although cement has played an important role in SOC construction, it has recently been increasingly recognized as a negative material for nature and the global environment.

특히 시멘트는 석회석 등을 사용할 뿐만 아니라 소성과정, 즉 클링커 제조 시 고온(약 1,500℃)상태에서 제조됨으로써 이 과정에서 시멘트 1톤을 생산하는데 0.7~1.0톤의 이산화탄소 가스를 배출하여 전 세계 온실 가스 배출량의 7~8%를 차지할 정도로 심각한 실정이다.In particular, cement is manufactured not only using limestone, but also at a high temperature (about 1,500℃) during the firing process, that is, during clinker manufacturing. It is a serious situation that accounts for 7-8% of the total.

우리나라에서 시멘트 생산량은 연간 약 6,300만 톤으로 약 5,670만 톤의 이산화탄소를 배출하여 철강산업에 이어 두 번째로 많이 배출하고 있다.Cement production in Korea is about 63 million tons per year, which emits about 56.7 million tons of carbon dioxide, the second largest emitter after the steel industry.

한편 세계 국가들은 1992년 브라질 리오에서 지구온난화 방지를 위한 기후변화 협약이 채택된 이후 지구온난화 문제가 인류 공동과제로 인식되었고, 세계 각국은 일찍부터 이에 대응방안을 마련하였다.Meanwhile, countries around the world recognized global warming as a common task for mankind after the adoption of the Convention on Climate Change to Prevent Global Warming in Rio, Brazil in 1992, and countries around the world prepared countermeasures from an early age.

특히, 1997년 일본 쿄토에서 기후변화협약에 관한 교토의정서가 채택된 이후, 2005년 교토의정서가 발효됨에 따라 세계 38개국의 선진국은 온실가스 감축의무를 준수해야 한다.In particular, since the Kyoto Protocol on the Climate Change Convention was adopted in Kyoto, Japan in 1997, and the Kyoto Protocol took effect in 2005, 38 developed countries around the world must comply with their greenhouse gas reduction obligations.

최근 2008년 7월에는 일본 도야코에서 열린 G8 정상회담에서 각국 정상들은 2050년까지 배출가스를 현재의 50%로 감축하는 방안을 검토하고 있다.Recently, at the G8 summit held in Toyako, Japan in July 2008, heads of state are considering reducing emissions by 50% by 2050.

이에 따라 시멘트 사용량을 최소화하기 위한 기술로, "석분을 포함하는 상온 강도발현 콘크리트 조성물 제조방법"(한국 등록특허공보 제10-1137717호, 특허문헌 4)에는 시멘트를 사용하지 않고 석분, 고로슬래그, 플라이애시를 혼합하여 결합재로써 사용하는 기술이 공개되어 있다.Accordingly, as a technology for minimizing the amount of cement used, "Method for producing a concrete composition containing stone dust that develops strength at room temperature" (Korean Registered Patent Publication No. 10-1137717, Patent Document 4) does not use cement, but uses stone dust, blast furnace slag, A technique of mixing fly ash and using it as a binder has been disclosed.

상기 특허문헌4에서는 석분 외에 고로슬래그, 플라이애시가 포함되는데, 다양한 연구에서 중금속이 발생하지 않았다는 보고가 있으나, 이런 성분이 미검출되는 것이 아닌 기준치 미만에 해당한다는 것일 뿐, 안전성이 완전히 확보된 것이라 보기 어려운 실정이다.In Patent Document 4, blast furnace slag and fly ash are included in addition to stone dust, and various studies have reported that heavy metals did not occur. It is difficult to see.

이때, 상기 무기성 파우더 100 중량부 대비 40 ~ 50 중량부의 흙이 더 포함될 수 있다.In this case, 40 to 50 parts by weight of soil may be further included based on 100 parts by weight of the inorganic powder.

It consists of any one selected from a mixture, calcium chloride, and sodium chloride.

이러한 첨가제는 무기성 파우더에 포함되어 있는 성분 중 강도 발현 및 결합력 발현에 부족한 성분을 채워주는 역할을 한다.These additives serve to fill the components that are lacking in the expression of strength and expression of binding force among the components included in the inorganic powder.

보다 구체적으로, 상기한 성분에서 황산염은 작업성을 용이하게 해주고, 강도를 높여주는 역할을 하게 된다.More specifically, in the above components, sulfate plays a role of facilitating workability and increasing strength.

즉, 상기한 첨가제의 성분에 따라 시멘트 사용량이 적음에도 불구하고 우수한 압축 강도를 가지며, 작업성이 양호하고, 상온에서 빠르게 양생이 끝날 수 있게 해주게 된다.That is, depending on the components of the above additives, despite the small amount of cement used, it has excellent compressive strength, good workability, and enables rapid curing at room temperature.

본 발명에서 무기성 파우더는 시멘트의 역할을 대채해주는 결합재의 역할과, 모래의 역할을 대채헤주는 골재의 역할을 모두 수행해주게 된다.In the present invention, the inorganic powder serves both as a binder that replaces the role of cement and as an aggregate that replaces the role of sand.

<첨가제의 제조><Manufacture of additives>

먼저, 표 1과 같은 조성으로 원료를 혼합하여 실시예와 비교예의 첨가제를 제조하였다.First, additives of Examples and Comparative Examples were prepared by mixing raw materials in the composition shown in Table 1.

<무기성 파우더의 제조><Manufacture of inorganic powder>

전북의 모 화강암 채석장에서 화강암 석분 슬러지를 공급받은 후, 이를 탈수기에 투입하여 탈수 처리하여 실시예 2의 무기성 파우더를 제조하였다.After receiving granite stone powder sludge from a granite quarry in Jeonbuk, it was put into a dehydrator and dehydrated to prepare inorganic powder of Example 2.

도 1은 제조한 무기성 파우더의 샘플 사진이다.1 is a photograph of a sample of the inorganic powder prepared.

준비된 무기성 파우더의 입자 구성을 실험장비(마이크로트랙 블루웨이브 입도분석기)로 분석한 결과 도 2에 도시된 바와 같이 전체적으로 0.5 ~ 500㎛의 입자 크기를 가지며, 입자 평균 크기는 30 ~ 32㎛인 것으로 나타났다.As a result of analyzing the particle composition of the prepared inorganic powder with experimental equipment (Microtrack Blue Wave particle size analyzer), as shown in FIG. appear.

뿐만 아니라, 작은 크기의 입자도 분포하기 때문에 일부 입자는 결합재의 역할도 할 수 있을 것으로 판단되었다.In addition, since small-sized particles are also distributed, it was determined that some of the particles could also serve as a binder.

한편, 준비된 무기성 파운더에 대해 한국 화학연구원에 성분 분석(EDX 분석 실험)을 의뢰하여 도 6에 나타내었다.On the other hand, component analysis (EDX analysis experiment) was requested to the Korea Research Institute of Chemical Technology for the prepared inorganic founder, and is shown in FIG. 6.

그런 다음 원통형 거푸집에 모르타르를 주입하고 양생시켜 원통형 시편(지름 30mm, 높이 60mm)을 제조하였다.Then, mortar was injected into the cylindrical mold and cured to prepare a cylindrical specimen (diameter 30 mm, height 60 mm).

양생 조건은 상온의 음지에서 2일간 1차 양생한 후, 탈형한 후 상온에서 7일간 2차 양생을 실시하였다.As for the curing conditions, the primary curing was performed in the shade at room temperature for 2 days, and then the secondary curing was performed at room temperature for 7 days after demolding.

제조된 시편은 28일 경과 후 압축강도를 측정하여 측정 결과를 아래 표 3에 나타내었다.The prepared specimens were measured for compressive strength after 28 days, and the measurement results are shown in Table 3 below.

상기 표 3을 보면 알 수 있듯이 실시예의 제품들이 비교예에 비해 압축강도가 우수한 것을 알 수 있다.As can be seen from Table 3, it can be seen that the products of Examples are superior in compressive strength to those of Comparative Examples.

특히, 비교예 7의 경우 무기성 파우더의 함량 대비 결합재(시멘트)의 함량이 상대적으로 적어 상온에서 양생시 조직이 치밀해지지 못하는 현상이 발생하는 것을 알 수 있다.In particular, in the case of Comparative Example 7, it can be seen that the content of the binder (cement) compared to the content of the inorganic powder is relatively low, so that the structure does not become dense during curing at room temperature.

<시편의 제조 및 압축 강도 측정 2 ><Manufacture of specimen and measurement of compressive strength 2>

비교예 1 내지 6의 첨가제 0.3g과, 실시예 2의 무기성 파우더 100g, 시멘트 20g을 배합하여 모르타르용 조성물을 제조하고, 여기에 물을 첨가한 후 교반하여 모르타르를 제조하였다.A mortar composition was prepared by mixing 0.3 g of the additives of Comparative Examples 1 to 6, 100 g of the inorganic powder of Example 2, and 20 g of cement, and water was added thereto and then stirred to prepare a mortar.

그런 다음 원통형 거푸집에 모르타르를 주입하고 양생시켜 비교예 8 내지 13의 원통형 시편(지름 30mm, 높이 60mm)을 제조하였다.Then, mortar was injected into the cylindrical mold and cured to prepare cylindrical specimens (diameter 30 mm, height 60 mm) of Comparative Examples 8 to 13.

시편은 상온에서 건조하여 28일 경과 후 압축강도를 측정하여 측정 결과를 실시예 3과 비교하여 아래 아래 표 4에 나타내었다.The specimen was dried at room temperature and after 28 days, the compressive strength was measured, and the measurement results were compared with Example 3 and are shown in Table 4 below.

상기 표 4를 보면 알 수 있듯이 첨가제의 조성이 실시예 3과 달리 이루어진 비교예 8 내지 13의 시편은 압축강도가 비교예 7과 비교하여 별달리 큰 개선이 이루어지지 못한 것으로 나타났다.As can be seen from Table 4, the compressive strength of the specimens of Comparative Examples 8 to 13, in which the composition of the additive was different from that of Example 3, was not significantly improved compared to that of Comparative Example 7.

이상의 결과를 보면 첨가제의 사용 여부, 첨가제의 조성 여부에 따라 본 발명과 달리 이루어진 비교예들의 경우 충분히 만족스러운 압축 강도를 갖지 못한 반면, 첨가제가 특별히 조성된 실시예의 경우 상온에서의 양생에도 불구하고 충분히 만족스러운 압축강도를 갖게 된 것을 알 수 있었다.Looking at the above results, the comparative examples made differently from the present invention depending on whether additives were used or not and whether or not the composition of additives did not have sufficiently satisfactory compressive strength, whereas in the case of examples in which additives were specially formulated, despite curing at room temperature, sufficient It was found to have a satisfactory compressive strength.

특히, 같은 실시예 중에서도 실시예 3과 실시예 4를 비교할 경우 무기성 파우더 100 중량부를 기준으로 시멘트가 대략 20 중량부 사용된 경우의 압축강도가 10 중량부 사용된 경우의 압축강도보다 훨씬 높게 나타났다.In particular, when comparing Example 3 and Example 4 among the same Examples, the compressive strength when approximately 20 parts by weight of cement was used based on 100 parts by weight of inorganic powder was much higher than the compressive strength when 10 parts by weight was used. .

본 발명에 따른 화강암 석분을 이용한 모르타르용 조성물은 전술한 도로 기저층, 자전거 도로, 벽돌, 보도 블록 외에도 표 6에 따른 강도 기준을 만족하는 다양한 토목 및 건축 용도로 활용될 수 있다 할 것이다.The composition for mortar using granite stone powder according to the present invention can be used for various civil engineering and construction purposes satisfying the strength criteria according to Table 6 in addition to the above-described road base layer, bicycle road, brick, and sidewalk block.
