Description
본 발명은 슬립방지용 표면 코팅된 폐유리골재를 이용한 콘크리트 및 그의 제조방법에 관한 것으로, 보다 상세하게는 경제성이 개선되는 슬립방지용 표면 코팅된 폐유리골재를 이용한 콘크리트 및 그의 제조방법에 관한 것이다.The present invention relates to concrete using waste glass aggregate coated with an anti-slip surface and a method for manufacturing the same. More specifically, it relates to concrete using waste glass aggregate with an anti-slip surface coating that improves economic efficiency and a method for manufacturing the same.
일반적으로 생활폐기물로 발생되는 폐유리의 약 50% 정도만이 재활용되고 있으며 건설용 대체재료로서의 재활용은 거의 없는 실정이다. 또한, 건설폐기물로 발생되는 폐유리는 혼합폐기물로 발생되어 분리 수거만 가능하면 재활용이 가능하지만 이의 재활용은 거의 이루어지지 못하고 있다.In general, only about 50% of waste glass generated as household waste is recycled, and recycling as an alternative material for construction is rare. In addition, waste glass generated as construction waste is generated as mixed waste and can be recycled as long as it can be collected separately, but recycling is rarely achieved.
여기서, 종래의 폐유리 재활용도는 블록원료, 그라스 대리석, 그라스타일, 유리섬유, 발포용 경량골재, 차선도색용 안료에 혼합되어 재활용되고 있으며, 선진외국의 경우에도 폐유리를 샌드블라스팅에 사용되는 실리카 대체물질, 진흙이나 타일, 콘크리트 벽돌 등의 첨가물로 이용하는 정도이나 무기재료인 시멘트 콘크리트에 사용하는 경우, 폐유리의 주성분인 반응성 실리카인 SiO2와 콘크리트중이 알카리 금속이온인 Na+, K+이 반응하여 알카리 규산염겔을 생성하고 물을 흡수하여 팽창하는 알카리 실리카 반응에 의한 균열발생으로 콘크리트를 급격히 열화시키는 문제등으로 인하여 사용이 극히 제한되고 있다. Here, the conventional waste glass is recycled by mixing it with block raw materials, grass marble, grass style, glass fiber, lightweight foam aggregate, and pigment for lane painting. Even in developed countries, waste glass is used for sandblasting. It is used as a substitute for silica and as an additive for mud, tiles, concrete bricks, etc., but when used in cement concrete, which is an inorganic material, SiO2, a reactive silica, the main component of waste glass, and Na+, K+, alkali metal ions in the concrete, react. Its use is extremely limited due to the problem of rapid deterioration of concrete due to cracks caused by the reaction of alkali silica, which produces an alkaline silicate gel and expands by absorbing water.
또한, 콘크리트 제조용 골재 부족의 해결 방안으로 폐유리를 분쇄하여 폐유리골재를 굵은골재의 대용으로 활용하였으나, 폐유리골재의 표면과 시멘트 몰탈 계면에서 슬립현상이 발생하여 콘크리트 강도발현에 문제점이 있었다. In addition, as a solution to the shortage of aggregate for concrete production, waste glass was crushed and the waste glass aggregate was used as a substitute for coarse aggregate, but there was a problem in developing concrete strength because a slip phenomenon occurred at the interface between the surface of the waste glass aggregate and the cement mortar.
즉, 폐유리골재의 매끄러운 표면으로 인해 시멘트에 혼합시 결합력이 저하됨에 따라 콘크리트의 강도가 저하되는 문제점이 있었다. In other words, due to the smooth surface of the waste glass aggregate, there was a problem that the strength of the concrete decreased as the bonding force decreased when mixed with cement.

상기의 해결 수단을 통하여, 본 발명은 다음과 같은 효과를 제공한다.Through the above solutions, the present invention provides the following effects.
첫째, 유리 재질의 분쇄폐유리 표면에 기설정된 입도 범위를 갖는 모래 미립분 코팅층이 다단 적층 형성된 폐유리골재가 포틀랜드 시멘트에 혼합시 증가된 표면 마찰에 의해 결합력이 증가되어 콘크리트의 강도가 현저히 개선될 수 있다. First, when waste glass aggregate, which is formed by layering a multi-stage coating layer of sand fine powder with a preset particle size range on the surface of crushed waste glass made of glass, is mixed with Portland cement, the bonding force increases due to increased surface friction, thereby significantly improving the strength of concrete. You can.
둘째, 열경화성수지 및 경화제가 1.5~2.5:1의 중량비 비율로 혼합된 수지가 침지된 분쇄폐유리의 표면에 건조된 모래 미립분이 1회 적층되되, 분쇄폐유리의 표면에 1차 적층된 모래 미립분에 다른 모래 미립분이 2차 적층되어 모래 미립분 코팅층이 형성되므로 시멘트의 혼합시에도 폐유리골재의 표면 마찰력이 안정적으로 유지될 수 있다. Second, dried sand fines are layered once on the surface of crushed waste glass immersed in a resin mixed with a thermosetting resin and hardener at a weight ratio of 1.5 to 2.5:1, and the sand fines are first layered on the surface of the crushed waste glass.

It includes a series of steps in which waste glass aggregate is formed (s30), and water, Portland cement, blast furnace slag, fly ash, fine aggregate, and waste glass aggregate are mixed and hardened to produce concrete (s40).
먼저, 유리 재질로 구비되는 폐유리가 기설정된 입도 범위를 갖도록 분쇄되어 분쇄폐유리(11)가 준비되고, 기설정된 입도 범위를 갖는 모래 미립분(12A)이 기설정된 건조시간동안 건조된다(s10). First, waste glass made of glass is pulverized to have a preset particle size range to prepare crushed waste glass 11, and sand fine powder 12A having a preset particle size range is dried for a preset drying time (s10) ).
여기서, 상기 분쇄폐유리(11)는 이산화규소(SiO2)를 포함하는 유리 재질로 구비되는 폐유리가 기설정된 입도 범위를 갖도록 분쇄되어 복수개 구비됨이 바람직하다. 이때, 상기 입도라 함은 상기 폐유리의 평균 지름을 의미한다. Here, the crushed waste glass 11 is preferably made of a glass material containing silicon dioxide (SiO 2 ) and is provided in plural pieces by being crushed to have a predetermined particle size range. At this time, the particle size means the average diameter of the waste glass.
또한, 상기 분쇄폐유리(11)의 입도 범위는 4.90~24.99mm로 설정될 수 있으며, 상기 모래 미립분(12A)의 입도 범위는 0.01~0.10mm로 설정됨이 바람직하다. 이에 따라, 후술되는 폐유리골재(10)의 입도 범위가 5~25mm로 설정되고, 상기 폐유리골재(10)는 10mm의 직경을 갖는 체거름망을 통과시 10~30%의 통과율을 가지며, 20mm의 직경을 갖는 체거름망을 통과시 30~70%의 통과율을 갖는 입도분포로 설정될 수 있다.In addition, the particle size range of the crushed waste glass 11 may be set to 4.90 to 24.99 mm, and the particle size range of the sand fine powder 12A is preferably set to 0.01 to 0.10 mm. Accordingly, the particle size range of the waste glass aggregate 10, which will be described later, is set to 5 to 25 mm, and the waste glass aggregate 10 has a passage rate of 10 to 30% when passing through a sieve with a diameter of 10 mm, and 20 mm When passing through a sieve with a diameter of , the particle size distribution can be set to have a passing rate of 30 to 70%.

In addition, it is preferable that the sand fine powder (12A) is prepared by drying for a preset drying time. At this time, the drying time is preferably set to 20 to 30 hours. At this time, if the drying time is set to less than 20 hours, there is a risk that the bonding force between the sand fine powder (12A) and the crushed waste glass 11 may be reduced due to moisture adsorbed on the sand fine powder (12A). On the other hand, if the drying time is set to exceed 30 hours, the time required to manufacture concrete increases, which may reduce productivity and economic efficiency. Therefore, as the drying time is set to 20 to 30 hours, the moisture adsorbed on the sand fine powder 12A is removed, thereby improving economic efficiency.

또한, 에폭시수지로서 구비된 상기 열경화성수지 및 상기 경화제가 1.5~2.5:1의 중량비 비율로 기설정된 혼합시간동안 혼합되어 상기 수지(13)가 준비되는 단계를 포함하되, 상기 혼합시간은 3~8분으로 설정됨이 바람직하다. 예컨대, 에폭시수지로서 구비된 상기 열경화성수지 및 상기 경화제가 2.0:1의 비율로 기설정된 혼합시간동안 혼합되되, 상기 혼합시간은 5분으로 설정될 수 있다. In addition, it includes the step of preparing the resin 13 by mixing the thermosetting resin provided as an epoxy resin and the curing agent at a weight ratio of 1.5 to 2.5:1 for a preset mixing time, wherein the mixing time is 3 to 8. It is desirable to set it in minutes. For example, the thermosetting resin provided as an epoxy resin and the curing agent are mixed at a ratio of 2.0:1 for a preset mixing time, and the mixing time may be set to 5 minutes.
여기서, 상기 열경화성수지 및 상기 경화제가 1.5:1 미만의 중량비 비율로 혼합되거나 2.5:1를 초과하는 중량비 비율로 혼합되는 경우 상기 열경화성수지 또는 상기 경화제 중 어느 하나의 일부가 화학반응되지 않고 잔여되어 상기 모래 미립분(12A)과 상기 분쇄폐유리(11) 간의 결합력이 저하될 우려가 있다. 따라서, 상기 열경화성수지 및 상기 경화제가 1.5~2.5:1의 중량비 비율로 혼합되어 상기 수지(13)가 준비됨에 따라 상기 모래 미립분(12A)과 상기 분쇄폐유리(11) 간의 결합력이 현저히 개선될 수 있다. Here, when the thermosetting resin and the curing agent are mixed at a weight ratio of less than 1.5:1 or mixed at a weight ratio exceeding 2.5:1, a portion of either the thermosetting resin or the curing agent remains without chemical reaction and remains. There is a risk that the bonding force between the sand fine powder 12A and the crushed waste glass 11 may decrease. Therefore, as the thermosetting resin and the curing agent are mixed at a weight ratio of 1.5 to 2.5:1 to prepare the resin 13, the bonding force between the sand fine powder 12A and the crushed waste glass 11 will be significantly improved.

This is desirable. For example, the crushed waste glass 11 is immersed in the resin 13, which is a mixture of the thermosetting resin provided as the epoxy resin and the curing agent, for a preset immersion time, and the immersion time may be set to 1 minute. .
이때, 상기 침지시간이 0.5분 미만으로 설정되는 경우 상기 분쇄폐유리(11) 표면에 상기 수지가 흡착되지 않아 상기 모래 미립분(12A)과 상기 분쇄폐유리(11) 간의 결합력이 저하될 우려가 있다. 반면에, 상기 침지시간이 2분을 초과하는 경우 상기 수지가 경화됨에 따라 상기 모래 미립분(12A)과 상기 분쇄폐유리(11) 간의 결합력이 저하될 우려가 있다. 따라서, 상기 침지시가이 0.5~2분으로 설정됨에 따라 상기 분쇄폐유리(11) 표면에 흡착된 상기 수지를 매개로 상기 모래 미립분(12A)과 상기 분쇄폐유리(11) 간의 결합력이 현저히 개선될 수 있다. At this time, if the immersion time is set to less than 0.5 minutes, the resin is not adsorbed on the surface of the crushed waste glass 11, and there is a risk that the bonding force between the sand fine powder 12A and the crushed waste glass 11 may be reduced. there is. On the other hand, if the immersion time exceeds 2 minutes, there is a risk that the bonding force between the sand fine powder 12A and the crushed waste glass 11 may decrease as the resin hardens. Therefore, as the immersion time is set to 0.5 to 2 minutes, the bonding force between the sand fine powder 12A and the crushed waste glass 11 will be significantly improved through the resin adsorbed on the surface of the crushed waste glass 11. You can.

It refers to a fine powder manufactured by pulverizing it into a fine powder.
이러한 고로슬래그는 잠재수경성을 가지고 있으며, 그 자체로 경화하는 성질은 미약하지만, 알칼리 자극으로 경화하는 특징이 있다. 또한, 고로슬래그는 포틀랜드 시멘트와 혼합할 경우 수산화칼슘이나 황산염의 작용에 의해 경화가 촉진되고 포틀랜드 시멘트만으로는 얻을 수 없는 우수한 콘크리트의 특성을 얻을 수 있다. 이때, 잠재수경성은 수산화기를 포함하는 알칼리시제가 소석회, 황산염 등의 자극을 받으면 박막이 파괴되며 이온이 용출됨에 따라 경화되는 특징을 의미한다.This blast furnace slag has latent hydraulic properties, and although its hardening property itself is weak, it has the characteristic of hardening with alkali stimulation. In addition, when blast furnace slag is mixed with Portland cement, hardening is accelerated by the action of calcium hydroxide or sulfate, and excellent concrete properties that cannot be obtained with Portland cement alone can be obtained. At this time, potential hydraulic hardening refers to the characteristic that when an alkaline reagent containing a hydroxyl group is stimulated by slaked lime, sulfate, etc., the thin film is destroyed and hardened as ions are eluted.
또한, 고로슬래그는 경화시 치밀한 조직으로 경화되어 염화물이온의 침투를 억제하며, 산화알루미늄 성분이 작용하여 염화물이온을 고정하는 프리델씨염(3CaO·Al2O3·CaCl2·10H20)를 생성한다.In addition, blast furnace slag hardens into a dense structure when hardened, suppressing the penetration of chloride ions, and contains Friedel's salt (3CaO·Al 2 O 3 ·CaCl 2 ·10H 2 0), which fixes chloride ions through the action of aluminum oxide. Create.
그리고, 상기 플라이애시는 상기 포틀랜드 시멘트에 혼합되되, 가공성이 개선되고 경화열이 완화됨과 동시에 포졸란 반응으로 장기 압축강도 및 수밀성이 향상되도록 혼합되며 이산화규소, 산화알루미늄, 및 산화철이 함유되어 구비될 수 있다. In addition, the fly ash is mixed with the Portland cement to improve processability, alleviate curing heat, and improve long-term compressive strength and watertightness through pozzolanic reaction, and may contain silicon dioxide, aluminum oxide, and iron oxide. there is.
여기서, 상기 플라이애시는 석탄의 연소시 잔류되는 불연성분으로 일반적으로 화력발전소 등에서 사용되는 석탄재로부터 추출되며, 이때 석탄재는 플라이애시(fly ash)와 바텀애시(bottom ash)로 구분된다. 상세히, 상기 플라이애시는 석탄이나 중유를 보일러 연료로 사용하는 화력발전소에서 연료의 연소과정에서 발생되는 회분을 굴뚝에서 전기 집진기로 포집한 연소재로서, 구상(球狀)인 입자 크기는 시멘트와 같은 정도이며 이산화규소 및 산화알루미늄이 주성분이고 산화철이 함유될 수 있다. 이러한 플라이애시는 상기 포틀랜드 시멘트에 혼합되어 사용하면 가공성이 개선되고 경화열이 완화됨과 더불어 포졸란 반응으로 장기적인 강도 및 수밀성이 향상되는 것으로 알려져 있다. Here, the fly ash is a non-combustible component remaining during combustion of coal and is generally extracted from coal ash used in thermal power plants, etc. At this time, coal ash is divided into fly ash and bottom ash. In detail, the fly ash is a combustion material obtained by collecting ash generated during the combustion process of fuel in a thermal power plant using coal or heavy oil as boiler fuel in the chimney using an electric precipitator. The fly ash is a spherical particle size similar to that of cement. The main ingredients are silicon dioxide and aluminum oxide, and may contain iron oxide. It is known that when such fly ash is used mixed with the Portland cement, processability is improved, curing heat is alleviated, and long-term strength and watertightness are improved through pozzolanic reaction.
여기서, 포졸란 반응은 포졸란 물질에서 용출된 이산화규소 및 산화알루미늄과 같은 가용성분이 시멘트 구성 화합물(C3S, C2S 등)에 수화시 생성된 수산화칼슘(Ca(OH)2)과 서서히 반응하여 불용성 칼슘실리케이트 수화물(C-S-H gel) 이나 칼슘알루미네이트 수화물(C-A-H gel)을 형성하여 그 조직을 더욱 치밀하게 만드는 반응을 의미한다. 그리고, 포졸란 물질은 그 자신만으로는 수경성을 갖지 않지만, 물에 용해 되어 있는 수산화칼슘과 상온에서 서서히 반응하여 물에 녹지 않는 화합물을 만들 수 있는 미분상태의 물질을 일컫는다. 이러한 포졸란 물질에는 응회암, 규조토와 같은 자연에서 얻을 수 있는 천연 포졸란과, 소성 점토, 실리카 겔, 실리카 흄, 플라이애시 등과 같이 인공적으로 만들어진 인공 포졸란이 있다. 이때, 고로슬래그의 잠재수경성과 플라이애시의 포졸란 반응은 물과 접촉하여 경화되는 공통점이 있으나, 잠재수경성은 소석회, 황산염 등의 알카리자극제와 반응하여 경화되고, 포졸란 반응은 수산화칼슘과 2차 반응하여 경화되는 차이점이 있다.Here, the pozzolanic reaction occurs when soluble components such as silicon dioxide and aluminum oxide eluted from the pozzolanic material slowly react with calcium hydroxide (Ca(OH)2) generated when hydrating cement constituent compounds (C3S, C2S, etc.) to form insoluble calcium silicate hydrate ( It refers to a reaction that makes the tissue more dense by forming C-S-H gel or calcium aluminate hydrate (C-A-H gel). In addition, pozzolanic materials do not have hydraulic properties on their own, but refer to materials in a finely divided state that can slowly react with calcium hydroxide dissolved in water at room temperature to create compounds that are insoluble in water. These pozzolanic materials include natural pozzolans that can be obtained from nature, such as tuff and diatomaceous earth, and artificial pozzolans that are made artificially, such as calcined clay, silica gel, silica fume, and fly ash. At this time, the latent hydraulic hardening of blast furnace slag and the pozzolanic reaction of fly ash have something in common: hardening by contact with water. However, the latent hydraulic hardening hardens by reacting with alkaline stimulants such as slaked lime and sulfate, and the pozzolanic reaction hardens by secondary reaction with calcium hydroxide. There is a difference.
