한편, 화력발전소에서 바텀애쉬와 플라이애쉬가 2:8의 비율로 발생되어지고 있는데, 플라이애쉬는 다른 공정을 거쳐서 정제된 균일한 품질의 제품이 생산되어지고 있으나, 바텀애쉬의 경우 어떠한 품질기준없이 회처리장에 매립되어지고 있는 실정이다. 이러한 바텀애쉬(bottom ash)는 미분탄 연소보일러의 저부에 낙하한 용융상태의 회(灰)들이 급냉, 고형화되어 암괴형태로 존재하는 것을 분쇄기를 사용하여 25mm이하의 입도로 분쇄시킨 것으로서, 총 석탄회 발생량의 10∼15% 정도가 발생한다. 이들 대부분은 1∼10mm 정도의 입경범위를 갖고 있으며, 건조밀도는 약 590 중량부정도이다. 전술한 바와 같이, 현재 대부분이 회처리장에 매립하고 있어 큰 규모의 회처리장을 필요로 하고 있으며 이는 막대한 건설비와 환경적으로 좋지 않은 영향을 미치고 있어 바텀애쉬의 대체처리방법이 요구되고 있는 실정이다.On the other hand, bottom ash and fly ash are generated in a ratio of 2: 8 in thermal power plants. Fly ash is produced with uniform quality of refined products through other processes, but bottom ash is without any quality standard. It is being buried in the ash processing plant. The bottom ash is a pulverized crushed ash that has fallen to the bottom of the pulverized coal combustion boiler and is crushed to a particle size of 25 mm or less using a crusher. About 10 to 15% of the time. Most of them have a particle size range of about 1 to 10 mm, and the dry density is about 590 parts by weight. As described above, most of them are buried in the ash processing plant, which requires a large amount of ash processing plant, which has an enormous construction cost and environmentally adverse effects, and thus requires an alternative treatment method of bottom ash.

따라서, 본 발명의 목적은 플라이애쉬 뿐만 아니라, 회처리장에 매립되는데 그치고 있는 바텀애쉬 등의 환경폐기물을 모래 등과 함께 사용하여, 종래의 입상토 충전재를 대신하여 비구조부재에 사용함으로써 화력발전소의 회처리장 규모와 발전소의 가동 수명을 연장할 수 있고, 타설 및 해체가 용이하고 우수한 시공성을 갖는 바텀애쉬를 함유하는 고유동성 충전 조성물을 제공하고, 또한 이의 제조방법을 제공하는데 있다.Accordingly, an object of the present invention is to use not only fly ash, but also environmental waste, such as bottom ash, which is being buried in an ash processing plant, with sand or the like, and used for non-structural members in place of conventional granular fillers. It is to provide a high fluidity filling composition containing a bottom ash that can extend the processing plant size and the operating life of the power plant, easy to place and dismantle, and has excellent workability, and also to provide a method for producing the same.

Show the slump flow value.

이하, 본 발명을 좀 더 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail.

전술한 바와 같이, 본 발명에서는 포틀랜트 시멘트를 주 성분으로 하여 환경폐기물인 플라이애쉬(fly ash)와 바텀애쉬(bottom ash)를 사용할 수 있다.As described above, in the present invention, fly ash and bottom ash, which are environmental wastes, may be used based on portland cement.

포틀랜트 시멘트는 통상적으로 무기물 형태의 충전재와 함께 사용되는 무기 시멘트로서, 모르타르, 콘크리트의 제조시에 사용하는 것으로 잘 알려져 있다.Portland cement is an inorganic cement commonly used with fillers in the form of minerals and is well known for use in the manufacture of mortars and concrete.

또한, 상기 플라이애쉬라 함은, 분탕을 보일러에서 연소할 때 나오는 폐가스 중 극히 미세한 입자를 일컬으며, 60% 정도의 실리카 SiO2를 함유하고 있고 시멘트와 결합하여 경화하는 성질이 있다. 또한, 다른 재료와 혼합할 경우에 유동성을 개선시키고, 시멘트 조성물을 도로에서와 같이 염을 포함하는 환경에서 사용할 때 유용한 첨가제로서 사용되어 오고 있다.In addition, the fly ash, which refers to the extremely fine particles of the waste gas when burning the boiling water in the boiler, contains about 60% of silica SiO 2 and has the property of curing in combination with cement. In addition, it has been used as an additive which improves fluidity when mixed with other materials and is useful when the cement composition is used in a salt-containing environment such as on a road.

전술한 바와 같이, 본 발명에 사용되어지는 바텀애쉬(bottom ash)는 미분탄 연소보일러의 저부에 낙하한 용융상태의 회(灰)들이 급냉, 고형화되어 암괴형태로 존재하는 것을 분쇄기를 사용하여 25mm이하의 입도로 분쇄시킨 것으로서, 총 석탄회 발생량의 10∼15% 정도가 발생한다. 대부분 1∼10mm 정도의 입경범위를 갖고 있으며, 건조밀도는 약 590중량부 정도이다. 이러한 바텀애쉬는 품질이 규격화되어있지 않지만 화학적 성분을 분석하면 플라이애쉬가 가지고 있는 성분보다 좋은 자경성을 나타낸다. 대부분의 성분들에서 플라이애쉬의 규격에 만족하지만 강열감량은 규정된 값보다 크게 나타난다. 강열감량은 공기와 흡착하여 강도를 저하시키는 작용을 하지만, 본 발명에 따른 혼합물의 적용은 저강도로 제어되기 때문에 강도저하를 문제시 할 필요가 없다. 또한 바텀애쉬를 사용하여 목표로 하는 강도를 발현하기 위한 단위시멘트량을 감소시킬수 있으며 폐자원을 활용하여 환경적으로 이롭고 잔골재인 모래를 대체하여 사용함에 따라 경제적으로 이롭다.As described above, the bottom ash used in the present invention is that the ash in the molten state dropped to the bottom of the pulverized coal combustion boiler is quenched and solidified and is present in the form of a rock, which is 25 mm or less using a grinder. It is ground to a particle size of about 10 to 15% of the total coal ash generated. Most have a particle size range of about 1 to 10 mm, and a dry density is about 590 parts by weight. Although these bottom ashes are not standardized in quality, their chemical composition is better than that of fly ash. Although most of the components meet the fly ash specification, the ignition loss is greater than the specified value. The loss on ignition acts to lower the strength by adsorbing with air, but the application of the mixture according to the present invention is controlled at low intensity so that there is no need to worry about the decrease in strength. In addition, it is possible to reduce the amount of unit cement to express the target strength by using the bottom ash, and it is economically beneficial by replacing sand, which is environmentally beneficial and fine aggregate, by utilizing waste resources.

본 발명에 있어서, 포틀랜드 시멘트의 사용량은 30∼120중량부, 플라이애쉬는 210∼280중량부, 바텀애쉬는 70∼280중량부, 모래 600∼1300중량부, 물 320∼460중량부로 사용하는데, 상기 성분들을 동시에 혼합하여 사용하거나, 또는 물을 제외한 다른 성분들을 혼합하여 건식 혼합법으로 배합하여 포장한 후 타설시에 물과 혼합하여 사용할 수도 있고, 또한 포틀랜드 시멘트, 플라이애쉬 및 바텀애쉬만을 건식으로 혼합하였다가 타설시에 물과 모래를 함께 혼합하여 사용하는 것도 가능하다.In the present invention, the amount of Portland cement used is 30 to 120 parts by weight, fly ash is 210 to 280 parts by weight, bottom ash is 70 to 280 parts by weight, sand 600 to 1300 parts by weight, water 320 to 460 parts by weight, The above components may be mixed at the same time, or other components except water may be mixed and packaged by dry mixing, and then mixed with water at the time of pouring. Also, only Portland cement, fly ash and bottom ash may be dried. It is also possible to mix and use water and sand together when pouring.

상기 포틀랜드 시멘트에 따라 강도를 변하는데, 포틀랜드 시멘트의 사용량이 30중량부 미만이면 초기 응결시간이 많이 소요되고 강도가 저하되고, 120중량부를 초과하면 굴착하기가 어렵게 된다. 따라서, 시멘트양은 적용분야의 굴착성에 따라 배합양을 조절하게 되며, 30∼120중량부가 바람직하다.The strength is changed according to the portland cement, if the amount of the portland cement is less than 30 parts by weight, the initial setting time takes a lot, the strength is lowered, if it exceeds 120 parts by weight it is difficult to excavate. Therefore, the amount of cement is to adjust the compounding amount according to the excavability of the application, 30 to 120 parts by weight is preferred.

또한 플라이애쉬의 사용량은 210∼280중량부가 바람직한데, 210중량부 미만이면 유동성이 감소하게 되고, 280중량부를 초과하면 경제성이 떨어지게 된다. 상기 플라이애쉬의 총양에 25∼100%의 비율로 바텀애쉬가 첨가되는 것이 바람직한데, 본 발명에 있어서는 70∼280중량부가 바람직하다. 이로서, 본 발명에 있어서 바텀애쉬는 시멘트와 플라이애쉬 같은 결합재로서의 역할과충진재로서의 잔골재의 역할도 겸하게 된다.In addition, the use amount of fly ash is preferably 210 to 280 parts by weight, but less than 210 parts by weight, the fluidity is reduced, and if it exceeds 280 parts by weight, the economy is inferior. Bottom ash is preferably added at a ratio of 25 to 100% to the total amount of the fly ash, but 70 to 280 parts by weight is preferable in the present invention. Thus, in the present invention, the bottom ash also serves as a binding material such as cement and fly ash, and also serves as a fine aggregate as a filler.

함께 사용하는 모래는 600∼1300중량부의 범위로 사용하는 것이 바람직하지만, 통상적으로 바텀애쉬의 양에 따라 그 양이 증가할수록 모래의 양을 감소시킨다.The sand used together is preferably used in the range of 600 to 1300 parts by weight, but in general, the amount of sand decreases as the amount thereof increases with the amount of bottom ash.

이러한 방법으로 혼합된 상기 바텀애쉬를 함유하는 충전 조성물는 28일 압축강도가 3∼83kgf/cm2이고, 슬럼프 플로우값이 20cm이상을 나타냄으로써, 타설 및 해체가 용이하게 되고, 따라서 다짐작업이 어려운 지역이나 시공이 어려운 지역에 채움재로서 사용될 수 있다. 또한, 강도는 포틀랜드 시멘트의 비율에 따라 조절될 수 있다.The filling composition containing the bottom ash mixed in this way has a compressive strength of 3 to 83 kgf / cm 2 for 28 days and a slump flow value of 20 cm or more, thereby making it easy to place and dismantle, thus making it difficult to compact. However, it can be used as a filling material in areas where construction is difficult. In addition, the strength can be adjusted according to the proportion of Portland cement.

또한, 본 발명에 따른 바텀애쉬를 함유하는 고유동성 충전 조성물은 굴착가능성에 따라 다음과 같이 나누어서 적용할 수 있다. 손도구를 이용하여 굴착할 수 있는 강도 7kgf/cm2이하, 및 기계를 이용하여 굴착할 수 있는 강도 7∼21kgf/cm2, 굴착하기 위해서는 전력장비가 필요하거나 굴착하지 못하는 강도 21kgf/cm2이상으로 나누어서 고려될 수 있다. 그러나, 주로 사용분야는 약 10∼15kgf/cm2정도의 강도를 요구하는 비구조부재에 효과적으로 사용될 수 있다. 예로서, 파이프의 하부충전, 옹벽의 배면충전, 지하실 및 지하탱크의 충전, 도로하부의 충전, 폐하수구의 충전 등에 사용되어질 수 있다. 또한, 슬럼프 플로우가 크기 때문에 셀프 레벨링(self leveling) 성질이 나타나 어떠한 공극이라도 잘 메꿔줄 수 있다.In addition, the high fluid filling composition containing the bottom ash according to the present invention can be divided and applied as follows according to the excavation potential. Strength that can be excavated using hand tools 7kgf / cm 2 or less, and a strength that can be excavated using machines 7~21kgf / cm 2, in order to digging or excavating is not necessary power equipment strength 21kgf / cm 2 or more Can be considered by dividing. However, the main field of use can be effectively used for non-structural members requiring strength of about 10 to 15 kgf / cm 2 . For example, it can be used for the bottom filling of pipes, the back filling of retaining walls, the filling of basements and underground tanks, the filling of the lower part of the road, the filling of the sewers, and the like. In addition, because of the large slump flow, self-leveling properties can be provided to fill any gaps well.

즉, 본 발명의 조성물은 유동성이 커서 지하공동부의 충전작업과 작업자의 접근이 어려운 장소의 충전 등에 이롭게 사용되어질 수 있다. 다짐작업이 필요없기 때문에 상수도 및 하수도의 관 매설시 다짐기계가 필요없고 작업자의 수도 줄일수 있다. 또한, 본 발명에 따른 충전 조성물은 바텀애쉬에 의해 색이 검은색을 나타내게 된다. 이러한 색은 이후 재굴착하였을 때 기존의 흙과의 차이에 의해서 용이하게 분리할 수도 있다.That is, the composition of the present invention can be advantageously used for filling the underground cavity and filling of places difficult for workers to access the fluidity. Since no compaction work is needed, compaction machines are not needed when laying water and sewer pipes, and the number of workers can be reduced. In addition, the filling composition according to the present invention is black by the bottom ash. These colors can be easily separated by the difference with the existing soil when reexcavated later.

본 발명에 있어서, 슬럼프 플로우는 7.62×15.24cm의 실린더 콘을 이용하여 측정하였고, 5×5×5cm의 공시체를 사용하여 28일 이후의 압축강도를 측정하였다.In the present invention, the slump flow was measured using a cylinder cone of 7.62 × 15.24 cm, and the compressive strength after 28 days was measured using a specimen of 5 × 5 × 5 cm.

하기 실시예를 통해 좀 더 구체적으로 본 발명을 살펴보지만, 이에 본 발명의 범주가 한정되는 것은 아니다.Looking at the present invention in more detail through the following examples, but the scope of the present invention is not limited thereto.
