본 발명은 산업폐기물인 플라이애쉬(Fly ash), 바텀애쉬(Bottom ash), 고로슬래그, 폐유리 가공분말, 폐제지 슬러지를 포함하는 콘크리트 혼화재 조성물, 상기 콘크리트 혼화재 조성물을 골재, 시멘트 및 물과 혼합하여 이루어지는 콘크리트 조성물 및 이로부터 제조된 콘크리트 구조물에 관한 것이다.The present invention is an industrial waste fly ash (Fly ash), bottom ash (Bottom ash), blast furnace slag, waste glass processing powder, concrete admixture composition including waste paper sludge, mixing the admixture with aggregate, cement and water It relates to a concrete composition and concrete structures produced therefrom.
바닷물의 생태계를 활성화시키기 위한 어초나 해안의 호안블럭 등은 대부분 대규모 공사이므로 사용되는 양이 매우 방대하다. 따라서 어초나 해안의 호안블럭을 설치하는 많은 양의 콘크리트가 요구된다. 종래에는 콘크리트의 구성성분으로 천연골재가 많이 사용되어 왔으므로, 이에 사용되는 천연골재도 상당 양이 필요하다. 그러나 최근, 하천 및 해양의 유지관리 및 보호 측면에서 골재 채취가 제한됨으로써 양질의 천연골재를 구하기가 점차 어려워져서 이에 대한 대체제의 개발이 요구되고 있다.Most of the reefs and coastal coastal blocks to revitalize the ecosystem of seawater are used extensively. Therefore, a large amount of concrete is required to install coastal or coastal coastal blocks. Conventionally, natural aggregates have been used as a component of concrete, so the natural aggregates used in this are also required. Recently, however, the collection of aggregates is limited in terms of maintenance and protection of rivers and oceans, and it is increasingly difficult to obtain high-quality natural aggregates, and development of alternatives is required.
해안의 어초나 호안블럭으로 사용되기 위해서는 콘크리트 제품의 강도가 210kgf/㎠이상, 비중이 2.5 이상이어야 한다. 일반 콘크리트를 사용할 경우 시멘트의 양을 규격대로 사용하면 상기와 같은 조건은 대체로 충족되지만, 호안블럭 등의 콘크리트 구조물은 대규모 공사여서 제조원가가 높아지게 되므로 원가절감이 절실하다. 따라서 보다 경제적으로 제품을 제조하기 위해서는 제품의 성능과 조건이 허락하는 한 최대한 원가가 낮은 폐기물 원료를 많이 사용하는 것이 유리하다.In order to be used as coastal reefs or shore banks, concrete products must have a strength of at least 210kgf / ㎠ and a specific gravity of at least 2.5. In the case of using general concrete, if the amount of cement is used as the standard, the above conditions are generally satisfied. However, the cost reduction is urgent because concrete structures such as rafting blocks are large-scale construction, which increases the manufacturing cost. Therefore, in order to manufacture the product more economically, it is advantageous to use as many raw materials as possible with the lowest cost as long as the performance and conditions of the product allow.
일반적으로 석탄화력 발전소에서 발생되는 부산물로서 석탄회는 연소로 내에서 석탄의 유기성 가연 성분이 연소된 후에 남는 잔류 광물질로 연소로의 하부로 배출되는 바텀애쉬와 연소 가스와 함께 상부로 배출되는 플라이애쉬로 구분된다. 이들 석탄회는 연소 설비 내에서 포집되는 위치가 다르기 때문에 소결 상태, 밀도, 입자의 크기 등 물성이 다르게 나타나게 된다.As a by-product of coal-fired power plants, coal ash is a residual ash that remains after the combustion of organic combustible components of coal in the furnace. It is a fly ash discharged to the upper side with bottom ash and combustion gas discharged to the bottom of the furnace. Are distinguished. Since these coal ashes are collected at different positions in the combustion plant, physical properties such as sintered state, density, and particle size are different.
플라이애쉬(Fly ash)는 연소과정에서 생성된 석탄회 중에서 미세한 크기의 입자로 연소 가스와 함께 연소로를 통과하여 배출되며, 총 석탄회 발생량의 75~90%를 차지하므로 일반적으로 석탄회라하면 이 플라이애쉬를 지칭한다. 플라이애쉬는 발전설비의 향상에 따라 균일한 품질의 제품이 생산되고 있으며, 그 재활용율이 점차 증가하여, 콘크리트 혼화재와 시멘트 원료로 활용되고 있다.Fly ash is a fine-sized particle of coal ash produced during the combustion process and is discharged through the combustion furnace along with the combustion gas.In general, fly ash is referred to as coal ash because it takes 75 to 90% of the total coal ash generated. Refers to. As a result of the improvement of power generation facilities, fly ash is produced with uniform quality products, and its recycling rate is gradually increasing, and is used as a concrete admixture and cement raw material.
한편, 바텀애쉬(Bottom ash)란 미분탄 연소 보일러의 저부에 낙하한 용융상태의 회들이 연소로 내에서 급냉, 고형화되어 암괴 형태로 존재하는 것을 분쇄기를 사용하여 25mm 이하의 입도로 분쇄시킨 것으로서, 총 석탄회의 10~15%정도가 발생한다. 일반적으로 분쇄기에 의해 파쇄된 바텀애쉬는 1~10mm 정도의 입경 범위를 갖고 있으며, 건조 밀도는 약 5 내지 90 중량부 정도이다. 클린커애쉬(clinker ash) 또는 배드애쉬(bad ash)라고도 하며, 현재 대부분이 회처리장에 매립되고 있어 큰 규모의 회처리장을 필요로 하고 있으며, 이는 막대한 건설비와 환경적으로 악영향을 미치고 있어 바텀애쉬의 대체처리방법이 요구되고 있는 실정이다.On the other hand, the bottom ash is a pulverized ash that is quenched and solidified in the combustion furnace, which has fallen to the bottom of the pulverized coal combustion boiler, is crushed to a particle size of 25 mm or less using a grinder. 10 to 15% of coal ash is produced. In general, the bottom ash crushed by the crusher has a particle size range of about 1 ~ 10mm, the dry density is about 5 to 90 parts by weight. Also known as clinker ash or bad ash, most of them are now buried in the ash processing plant, which requires a large amount of ash processing plant, which has a huge construction cost and environmentally negative effect on bottom ash. There is a demand for an alternative treatment method.
근래들어 바텀애쉬와 플라이애쉬를 사용하여 콘크리트 구조물을 제조하는 여러 가지 방법이 제시되고 있는데, 예를 들면 아래와 같다.Recently, various methods for manufacturing concrete structures using bottom ash and fly ash have been proposed. For example,
특허등록 제429669호는 폐기물인 5mm이하의 바텀애쉬를 모래의 대체재로서 사용하되, 물, 시멘트, 모래, 자갈, 감수제, 배합수 등으로 배합하여 된 콘크리트 조성물에서 모래 단위량의 5-40% 첨가하는 것을 특징으로 하는 콘크리트 조성물을 개시하고 있다. 그러나 상기 특허의 경우에는 폐기물인 바텀애쉬만을 대체제로서 사용함으로써 사용되는 폐기물의 양이 적어 비경제적일 뿐만 아니라, 석탄회 등을 함께 사용할 경우 얻을 수 있는 장기강도와 내투수성 등의 장점을 활용할 수 없는 문제점이 있다.Patent No. 429669 uses 5mm or less of bottom ash as a substitute for sand, but adds 5-40% of the unit weight of sand in the concrete composition by mixing it with water, cement, sand, gravel, water reducing agent, and mixing water. Disclosed is a concrete composition characterized in that. However, in the case of the patent, by using only the bottom ash, which is a waste, as a substitute, the amount of waste used is not economical, and the advantages such as long-term strength and water permeability obtained by using coal ash together cannot be utilized. There is a problem.
특허등록 제447739호는 폐기물인 바텀애쉬를 콘크리트 조성물로 사용하되, 시멘트 15-30중량%, 입경 5-20mm의 바텀애쉬 15-45중량%, 입경 5mm이하의 바텀애쉬 20-35% 및 석분 10-20중량%로 이루어진 콘크리트 조성물을 개시하고 있다. 또한 여기에 5-15중량%의 레드머드를 부가적으로 첨가하여 사용할 수 있다고 개시되어 있다. 즉 조골재와 세골재의 대체재로서 바텀애쉬를 사용하여 호안블럭으로 요구되는 조건이 충족될 수 있음을 개시하고 있다. 그러나 석탄회나 고로슬래그와 같은 자체수경성을 가지는 재활용 물질을 함께 사용하지 않음으로서 상대적인 시멘트의 사용량이 증가하여 경제성이 떨어지는 문제점이 있다.Patent registration No. 447739 uses waste bottom ash as concrete composition, but cement 15-30% by weight, bottom ash 15-45% by weight 5-20mm, bottom ash 20-35% and 5 mm Disclosed is a concrete composition consisting of -20% by weight. It is also disclosed that 5-15% by weight of red mud can be additionally added thereto. That is, using the bottom ash as a substitute for coarse aggregate and fine aggregate, it is disclosed that the conditions required for the relief block can be satisfied. However, there is a problem in that the economic efficiency is lowered because the use of relative cement is increased by not using recyclable materials having self-hydration such as coal ash or blast furnace slag.
특허출원공개 제2003-64572호는 폐기물인 바텀애쉬를 사용하는 콘크리트 조성물에 관한 것으로써, 시멘트 15-30중량%, 2.5mm 이하의 바텀애쉬 잔골재 20-40%, 25mm 이하의 자연산 굵은 골재 30-50중량%로 이루어진 콘크리트 조성물을 개시하고 있다. 또한 시멘트 15-30중량%, 모래 20-40중량%, 자갈의 대체재로서 입경 25mm이하의 바텀애쉬 굵은 골재 30-50중량%로 이루어진 콘크리트 조성물도 개시되어 있 다. 게다가 시멘트 17-28중량%, 모래의 대체재로서 입경이 2.5mm이하인 바텀애쉬 잔골재 20-35중량%, 자갈의 대체재로서 입경이 25mm이하인 바텀애쉬 굵은 골재 30-45중량% 및 석분 5-10중량%로 이루어진 콘크리트 조성물도 개시되어 있다.Patent Application Publication No. 2003-64572 relates to a concrete composition using a bottom ash as a waste, 15-30% by weight of cement, 20-40% of bottom ash fine aggregate of 2.5mm or less, coarse aggregate of less than 25mm Disclosed is a concrete composition consisting of 50% by weight. Also disclosed is a concrete composition composed of 15-30% by weight of cement, 20-40% by weight of sand, 30-50% by weight of bottom ash coarse aggregate of 25 mm or less as a substitute for gravel. In addition, 17-28% by weight of cement, 20-35% by weight of bottom ash fine aggregate having a particle size of 2.5mm or less as a substitute for sand, 30-45% by weight of thick bottom ash aggregate having a particle size of 25mm or less as a substitute for gravel, and 5-10% by weight of stone powder Also disclosed is a concrete composition.
그러나 상기와 같이 모래의 대체재로서 입경 2.5mm이하의 바텀애쉬 잔골재를, 자갈의 대체재로서 입경 25mm이하의 바텀애쉬 굵은 골재를, 또는 모래와 자갈의 대체재로서 석분과 함께 특정 입경의 바텀애쉬를 사용하는 경우, 바텀애쉬 만이 골재대용으로 과다하게 사용되어 제품의 강도저하 또는 내투수성 등의 문제가 나타날 수 있고, 재활용 물질을 어느 한도 이상 첨가할 수 없게 되어 역시 경제성이 떨어지는 문제점이있다. However, as described above, a bottom ash fine aggregate having a particle size of 2.5 mm or less as a substitute for sand, a thick ash aggregate having a particle size of 25 mm or less as a substitute for gravel, or a bottom ash having a specific particle size together with stone powder as a substitute for sand and gravel is used. In this case, only the bottom ash is excessively used as a substitute for aggregates, which may cause problems such as reduced strength or water permeability of the product, and there is also a problem in that it is impossible to add more recycled materials to the limit, thereby lowering economic efficiency.
특허출원공개 제2002-55481호에는 포틀랜드 시멘트 30-120중량부, 플라이애쉬 210-280중량부, 바텀애쉬 70-280중량부, 모래 600-1300중량부 및 물 320-460중량부를 혼합하여 이루어지며, 3-83kgf/㎤의 28일 압축강도 및 20㎝ 이상의 슬럼프 플로우 값을 나타내는 것을 특징으로 하는 바텀애쉬를 함유하는 고유동성 충전 조성물이 개시되어 있다.

그러나 이러한 조성물로 된 콘크리트 구조물은 압축강도가 3-83kgf/㎤로서 호안블럭 등으로 사용되기 위한 콘크리트 구조물로서의 충분한 압축강도를 갖지 않게 되어 제품의 용도가 매우 제한되는 문제점이 있다.However, the concrete structure made of such a composition has a problem that the use of the product is very limited because the compressive strength does not have sufficient compressive strength as a concrete structure for use as a relief block as 3-83 kgf / cm 3.
본 발명은 상기와 같은 문제점을 해결하기 위해 이루어진 것으로서, 일반 콘크리트 조성물에 사용되는 골재 및 시멘트를 대체하여 사용될 수 있는 생산원가가 저렴한 폐기물을 이용한 콘크리트 혼화재 조성물을 제공하는 것이다.The present invention has been made to solve the above problems, it is to provide a concrete admixture composition using the waste of low production cost that can be used to replace the aggregate and cement used in the general concrete composition.

이하, 본 발명에 대하여 보다 구체적으로 기술한다.Hereinafter, the present invention will be described in more detail.
콘크리트 구조물은 굵은 골재 1000중량부, 잔골재 700중량부, 시멘트 300중 량부, 물 200중량부로 구성되는 것이 일반적이다. 해안의 어초나 호안블럭 또는 해안용 블럭으로 사용되는 콘크리트 구조물은 콘크리트 제품의 강도가 210kgf/㎠ 이상, 비중이 2.5 이상이어야 한다.Concrete structures are generally composed of 1000 parts by weight of coarse aggregate, 700 parts by weight of fine aggregate, 300 parts by weight of cement, and 200 parts by weight of water. Concrete structures used for coastal reefs, shore blocks or coastal blocks should have a strength of at least 210kgf / ㎠ and a specific gravity of at least 2.5.
본 발명의 콘크리트 혼화재 조성물은 플라이애쉬, 고로슬래그, 바텀애쉬 및 폐유리 가공분말을 포함하며, 이에 추가로 폐제지 슬러지를 포함할 수 있다.The concrete admixture composition of the present invention includes fly ash, blast furnace slag, bottom ash and waste glass processing powder, and may further include waste paper sludge.
본 발명에서 사용되는 플라이애쉬(fly ash)는 매우 미세한 분말로서 자체 수경성을 가지는 것으로서, 시멘트의 대체재로 사용할 수 있는 물질이며, 콘크리트의 치밀성을 증가시켜 해수로부터 제품의 부식에 대한 내구성을 증가시켜 주는 역할을 한다. 플라이애쉬는 시멘트의 대체재로 10~90중량부를 사용하는 것이 좋으며, 보다 바람직하게는 30-70중량부를 사용할 수 있다. 이 범위 내에서 첨가된 플라이애쉬는 제품의 장기 강도와 치밀성을 증대시켜 해수로부터의 부식에 대한 내구성을 증대시켜준다. 그러나 10중량부 이하로 플라이애쉬를 사용하면 경제성이 떨어지며, 100중량부 이상으로 너무 과다하게 사용하는 경우 충분한 강도 발현시간이 지나치게 지연된다.Fly ash (fly ash) used in the present invention is a very fine powder and has its own hydraulic properties, which can be used as a substitute for cement, and increases the compactness of concrete to increase the durability against corrosion of products from seawater. Play a role. The fly ash is preferably used 10 to 90 parts by weight as a substitute for cement, more preferably 30 to 70 parts by weight. Fly ash added within this range increases the long-term strength and compactness of the product, increasing its durability against corrosion from seawater. However, when the fly ash is used at 10 parts by weight or less, the economical efficiency is reduced, and when excessively used at 100 parts by weight or more, sufficient strength expression time is excessively delayed.
상기 고로 슬래그의 경우는 보온재, 방음재로 사용되는 슬래그울, 특수비료, 고로시멘트, 고로 벽돌의 원료로 광범위하게 사용되는 것으로서, 해수 등에 대한 내식성을 증가시키는 물성을 갖지는 않지만, 자체 수경성을 갖고 비중도 커서 시멘 트 대체재로서 일반적으로 많이 사용되고 있는 물질이다. 시멘트 대체재로 고로슬래그는 10~150중량부, 보다 바람직하게는 50-100중량부를 사용하는 것이 좋다. 이 범위 내에서 고로슬래그를 시멘트 대체재로 사용하는 경우에는 제품의 강도도 충분히 발현되어 요구되는 콘크리트 강도를 충족시킬 수 있으며, 가격이 시멘트보다 저렴하므로 경제적인 잇점이 있다. 그러나 너무 과다하게 사용할 경우에는 제품에 크랙이 심하게 생기는 등의 문제가 발생되어 바람직하지 않다.The blast furnace slag is widely used as a raw material of the insulation material, slag wool used as sound insulation, special fertilizer, blast furnace cement, blast furnace brick, it does not have physical properties to increase the corrosion resistance to seawater, but has its own hydraulic properties and specific gravity It is also a commonly used material as a cement cement substitute. As a cement substitute, blast furnace slag may be used in an amount of 10 to 150 parts by weight, more preferably 50 to 100 parts by weight. In the case of using the blast furnace slag as a cement substitute within this range, the strength of the product is also sufficiently expressed to meet the required concrete strength, and the price is cheaper than cement, so there is an economic advantage. However, if excessively used, problems such as severe cracking of the product occur, which is not preferable.
상기 바텀애쉬(bottom ash)는 자체 수경성은 없으나, 매우 고온에서 형성된 다공질의 유리질 물질로서 그 자체가 해수 등에 의한 부식에 대한 내구성을 가지고 있어 이를 혼합하여 사용할 경우 해수에 대한 내식성을 증대시킨다. 또한 바텀애쉬는 그 조직이 다공성으로서 투수성이 양호하고, 약간의 포졸란 특성도 가지고 있어 장기강도 발현을 나타내는 특성을 갖는다. 또한, 식물의 성장에 필수적인 흡수성이 양호하고, 상기한 바와 같이 다공성 구조로 되어 있으므로 식물의 뿌리내림이 용이한 특성을 갖는 등, 대형 녹화용 호안블럭이 요구하는 여러 가지 조건을 충족시킬 수 있는 장점을 가지고 있다.The bottom ash has no hydraulic property of its own, but is a porous glass material formed at a very high temperature, and thus has resistance to corrosion by seawater, thereby increasing corrosion resistance to seawater when used in a mixture thereof. In addition, the bottom ash has a characteristic that the tissue is porous, has good water permeability, and has a slight pozzolanic property and thus shows long-term strength expression. In addition, the water absorption essential for plant growth is good, and the porous structure as described above has the advantage that can easily meet the various conditions required by large-sized green revetment block, such as easy to take root of the plant characteristics Have
표 1은 본 발명에서 사용된 산업폐기물인 바텀애쉬의 구성성분을 분석하여 나타낸 것이다.Table 1 shows the analysis of the components of the bottom ash which is an industrial waste used in the present invention.
바텀애쉬는 굵은 골재의 대체재로 사용할 수 있는 물질이다. 5-20mm 입경의 바텀애쉬를 굵은 골재 대체재로 100~500중량부, 보다 바람직하게는 200-400중량부를 사용할 수 있다. 이러한 범위 내에서 바텀애쉬를 사용하면 해수에 대한 내산성을 증가시킬 수 있다. 이는 바텀애쉬가 매우 고온에서 형성된 다공질의 유리질 물질이기 때문이다. 그러나 바텀애쉬의 양을 너무 과다하게 혼합하면 바텀애쉬에 함유되어 있는 약 10~20%의 미연탄소분이 물을 흡수하게 되어 시멘트에 대한 물 소요량이 증가하게 되며, 결과적으로 제품의 강도가 저하되어 콘크리트로서 요구되는 강도를 충족시킬 수 없게 된다.Bottom ash is a material that can be used as a substitute for coarse aggregate. 100 to 500 parts by weight, and more preferably 200 to 400 parts by weight, may be used as a substitute for coarse aggregate with a bottom ash having a particle diameter of 5-20 mm. Using bottom ash within these ranges can increase acid resistance to seawater. This is because bottom ash is a porous glassy material formed at very high temperatures. However, if the amount of bottom ash is mixed too much, about 10-20% of unburned carbon content in the bottom ash absorbs water, which increases the water requirement for cement. As a result, the required strength cannot be met.
또한, 상기 폐유리 가공분말은 브라운관과 같은 유리제품을 기계적으로 가공할 때 발생되는 산업폐기물로서 잔골재의 대체재로 사용될 수 있다. 잔골재 대체재로 사용하는 경우, 폐유리 가공분말은 100~700중량부의 범위 내에서 사용할 수 있다. 상기 폐유리 가공분말은 매우 미세한 분말로서 비교적 큰 비중을 가지고 있고, 모래와 유사한 규소성분으로 이루어져 있으므로, 시멘트와 혼합될 경우 칼슘, 알루미늄 성분 등과 반응이 진행되어 시멘트와 결합할 수 있으며, 그 자체가 미세 충진제로서의 역할도 수행하여 제품의 치밀도와 비중을 높이는 역할을 하게 된다. 따라서 상기 범위 내에서 폐유리 가공분말을 사용하는 것이 바람직하다.In addition, the waste glass processing powder may be used as a substitute for fine aggregates as industrial waste generated when mechanically processing glass products such as CRT. When used as a substitute for fine aggregates, waste glass processed powder can be used within the range of 100 to 700 parts by weight. The waste glass processing powder is a very fine powder and has a relatively large specific gravity, and is composed of a silicon component similar to sand, and when mixed with cement, the waste glass processed powder may react with calcium, aluminum, and the like to bind to cement. It also serves as a fine filler to increase the density and specific gravity of the product. Therefore, it is preferable to use waste glass processing powder within the above range.
그러나 지나치게 사용할 경우, 유리에 첨가되어 있는 불순물 등의 효과에 의해 에트린자이트의 형성을 방해하여 강도를 저하시키므로 바람직하지 않으며, 100중량부 미만으로 사용할 경우에는 미세충전제로서 폐유리 가공분말의 사용에 의해 얻어지는 물리적 및 경제적 효과가 미미하여 바람직하지 않다. 보다 바람직하게는 200-600중량부의 범위 내에서 사용할 수 있다.However, when excessively used, it is not preferable because it inhibits the formation of ethrinite by effects such as impurities added to the glass and lowers the strength. When using less than 100 parts by weight, use of waste glass processed powder as a fine filler The physical and economic effects obtained by the insignificant effect are negligible. More preferably, it can be used within the range of 200-600 parts by weight.
상기 폐제지 슬러지는 일부가 바닷물 속에서 미생물에게 영양분을 공급해주는 역할을 하는 것으로서 충진물질로 사용되며, 전체 제품의 10~400중량부를 첨가할 수 있다. 상기와 같은 범위에서 폐기물인 폐제지 슬러지를 사용하면 제품의 강도를 증가시킬 수 있으며, 원가 절감의 효과를 얻을 수 있지만, 과다하게 사용할 경우 제품의 비중이 낮아질 수 있다. The waste paper sludge is used as a filler as part of the nutrient supply to microorganisms in sea water, and may be added 10 to 400 parts by weight of the whole product. The use of waste paper sludge as waste in the above range can increase the strength of the product, and can reduce the cost, but if used excessively, the specific gravity of the product can be lowered.
본 발명의 콘크리트 조성물은 상기 콘크리트 혼화재 조성물을 굵은 골재, 잔골재, 시멘트 및 물을 혼합하여 이루어진다.Concrete composition of the present invention is made by mixing the concrete admixture composition coarse aggregate, fine aggregate, cement and water.
보다 구체적으로는, 상기 콘크리트 조성물은 굵은 골재 600~1000중량부, 잔골재 100~600중량부, 시멘트 100~300중량부, 물 100-200중량부 및 상기 콘크리트 혼화재 조성물 100~1000중량부를 포함하며, 상기 조성물을 혼합하여 콘크리트 구조물을 제조할 수 있다. 상기 제조된 콘크리트 구조물은 어초나 호안블럭, 용승로 블럭, 또는 해안용 구조물일 수 있으며, 특히 바텀애쉬가 식물 성장에 필요한 흡수성이 양호하고, 다공성 구조로 되어 식물의 뿌리내림이 용이하므로 대형 녹화용 호안블럭에 적합하게 사용될 수 있다.More specifically, the concrete composition includes 600 to 1000 parts by weight of coarse aggregate, 100 to 600 parts by weight of fine aggregate, 100 to 300 parts by weight of cement, 100 to 200 parts by weight of water and 100 to 1000 parts by weight of the concrete admixture composition, The composition may be mixed to prepare a concrete structure. The manufactured concrete structure may be a reef or a raft block, a waterway block, or a coastal structure, in particular, the bottom ash has good absorbency necessary for plant growth, and has a porous structure to facilitate rooting of the plant, thus allowing for large greening. It can be used suitably for a lake block.
이하, 본 발명을 실시예를 들어 상세하게 설명하나, 이로써 본 발명을 한정하는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to Examples, but the present invention is not limited thereto.
실시예 1Example 1
플라이애쉬 70중량부, 고로슬래그 90중량부, 바텀애쉬(평균입도 10mm) 300중량부 및 폐유리분말(평균입도 1mm이하) 400중량부를 혼합하여 콘크리트 혼화재 조성물을 제조하였다.A concrete admixture composition was prepared by mixing 70 parts by weight of fly ash, 90 parts by weight of blast furnace slag, 300 parts by weight of bottom ash (average particle size of 10 mm) and 400 parts by weight of waste glass powder (average particle size of 1 mm or less).
실시예 2Example 2
상기 실시예 1에 폐제지슬러지 300중량부를 추가로 혼합하여 콘크리트 혼화재 조성물을 제조하였다.Further mixing 300 parts by weight of the waste paper sludge in Example 1 to prepare a concrete admixture composition.
실시예 3 및 4Examples 3 and 4
굵은 골재 700중량부, 시멘트 100중량부, 잔골재 300중량부, 상기 실시예 1 및 2에서 제조된 혼화재 조성물 300중량부, 및 물 200중량부를 혼합하여 직경 10cm, 높이 20cm의 원통형 콘크리트 공시체를 제작하였다. 이러한 콘크리트 시편에 대한 재령에 따른 압축강도를 조사하여 그 결과를 도 1 및 도 2에 나타내었다.700 parts by weight of coarse aggregate, 100 parts by weight of cement, 300 parts by weight of fine aggregate, 300 parts by weight of the admixture composition prepared in Examples 1 and 2, and 200 parts by weight of water were mixed to prepare a cylindrical concrete specimen having a diameter of 10 cm and a height of 20 cm. . The compressive strength according to the age of the concrete specimens were investigated and the results are shown in FIGS. 1 and 2.
조사결과 실시예 3은 7일만에 240kgf/㎠의 강도를 나타내었고, 28일 후에는 320kgf/㎠까지 강도가 상승하여 콘크리트 구조물로서 충분한 강도를 가짐을 확인하였고, 또한, 비중은 2.76을 나타내어 용도에 충분한 값을 갖는 것으로 나타났다. 실시예 4의 경우는 7일만의 압축강도가 220kgf/㎠ , 28일 강도가 300kgf/㎠ 을 나타났으며, 비중은 폐제지 슬러지의 사용으로 약간 감소하였으나, 2.58로서 사용하기에 충분한 값을 가짐을 확인하였다.As a result, Example 3 showed the strength of 240kgf / cm2 in 7 days, and after 28 days, the strength was increased to 320kgf / cm2, and it was confirmed that it had sufficient strength as a concrete structure, and the specific gravity was 2.76. It was shown to have a sufficient value. In the case of Example 4, the compressive strength after 7 days was 220kgf / ㎠, the 28-day strength was 300kgf / ㎠, and the specific gravity was slightly decreased by the use of waste paper sludge, but it was sufficient to be used as 2.58. Confirmed.
동일한 공시체를 대상으로 US Bureau of Reclamation Test Method 4908B에 따라 황산염 저항성을 시험하여 일반 콘크리트와의 비교 결과를 도 2에 나타내었다. 도 2에 따르면 황산염 저항성이 일반 콘크리트에 비해 더 높은 것을 알 수 있다. 일반 콘크리트는 침지 200일에서 0.040%로 나타났지만, 본 발명에 따른 산업폐기물을 혼합한 콘크리트는 0.022%정도로 상대적으로 낮게 나타났다.Sulfate resistance was tested in accordance with US Bureau of Reclamation Test Method 4908B for the same specimen, and the results of comparison with general concrete are shown in FIG. 2. According to Figure 2 it can be seen that the sulfate resistance is higher than the general concrete. General concrete was found to be 0.040% in 200 days of immersion, but the concrete mixed with industrial waste according to the present invention was relatively low, about 0.022%.
이와 같은 시험 결과로부터 본 발명에 의한 혼화제 조성물을 사용함으로써 호안블럭, 용승로블럭이나 해안 구조물과 같은 콘크리트 구조물로서 필요한 충분한 강도와 비중을 가지며, 내식성도 보다 강화됨을 알 수 있다.From these test results, it can be seen that the use of the admixture composition according to the present invention has sufficient strength and specific gravity necessary as concrete structures such as a lake block, a water pass block, or a coastal structure, and also improves corrosion resistance.
상술한 바와 같이 산업폐기물인 바텀애쉬, 플라이애쉬, 고로슬래그, 폐유리 가공분말 및 폐제지 슬러지를 콘크리트 혼화용 조성물로 사용함으로써, 콘크리트 구조물로서 요구되는 강도와 비중을 갖고, 바닷물에 의해 부식되는 것을 완화시켜주는 역할을 하여 내구성이 우수하며, 황산염에 대한 저항성이 일반 콘크리트 구조물보다 우수한 콘크리트 구조물을 얻을 수 있게 된다.As described above, by using industrial ash bottom ash, fly ash, blast furnace slag, waste glass processing powder and waste paper sludge as the composition for concrete admixture, it has the strength and specific gravity required as concrete structure, and it is corroded by sea water. It has a role of mitigating and excellent in durability, and it is possible to obtain a concrete structure having better resistance to sulfate than a general concrete structure.
또한, 본 발명에 따른 산업 폐기물을 이용한 콘크리트 혼화재 조성물을 일반 콘크리트 조성물과 혼합하여 콘크리트 구조물을 제조함으로써, 원가절감 효과를 얻게 되고 천연 골재의 채취 곤란을 극복할 수 있음은 물론, 폐기 매립처리되고 있는 폐기물을 건설 자원으로 활용함으로써 환경보존에도 기여하게 되는 효과가 얻어진다.In addition, by mixing the concrete admixture composition using the industrial wastes according to the present invention with a general concrete composition to produce a concrete structure, it is possible to obtain a cost-saving effect and overcome the difficulty of collecting natural aggregate, as well as being disposed of landfill The use of waste as a construction resource has the effect of contributing to environmental conservation.
나아가 바텀애쉬의 흡수성과 다공성으로 인해 식물의 뿌리 내림이 용이하여 식물성장을 가능하게 하여 해양의 환경 보호에도 기여하는 효과도 얻을 수 있다.Furthermore, due to the absorption and porosity of the bottom ash, it is easy to take root of the plant, thereby enabling plant growth and contributing to the environmental protection of the ocean.
