본 발명은 폐광산 광미(폐광미)를 충전재로서 활용한 폴리머 모르타르 및 콘크리트에 관한 것으로서, 보다 상세하게로는 폴리머 모르타르 및 콘크리트에 사용되는 충전재의 일부 또는 전체를 폐광미로 치환하는 구성으로 강도특성이 개선되고, 폐광미 사용에 따른 경화지연 현상을 특수 촉진제-개시제 시스템을 통해 극복하도록 하는 폐광산 광미를 충전재로 활용한 폴리머 모르타르 및 콘크리트에 관한 것이다.The present invention relates to a polymer mortar and concrete using waste mine tailings (waste tailings) as a filler, and more specifically, to improve the strength characteristics by replacing part or all of the fillers used in the polymer mortar and concrete with waste tailings. The present invention relates to a polymer mortar and concrete using waste mine tailings as a filler to overcome the curing delay caused by the use of waste tailings through a special accelerator-initiator system.
일반적으로 폴리머 모르타르 및 콘크리트 제조시 사용되는 충전재는, 수지의 증량, 성형성 개선, 내마모성 및 내열성의 향상, 수축의 저감 및 균열 방지 등 각종 성능향상을 목적으로 사용되어지는 미립자 상의 골재로서, 그 특성은 수지의 흡착량이 크지 않고, 성형물의 외관이나 제물성을 저하 시키지 않아야 하며, 비중이 크지 않고, 입자의 형상 및 크기가 적당해야 한다.Generally, fillers used in the production of polymer mortars and concrete are aggregates of fine particles used for the purpose of increasing performance of resins, improving moldability, improving wear resistance and heat resistance, reducing shrinkage, and preventing cracks. The adsorption amount of the silver resin should not be large, the appearance or product properties of the molded product should not be reduced, the specific gravity should not be large, and the shape and size of the particles should be appropriate.
그리고, 폴리머 모르타르 및 콘크리트에서 충전재로는, 탄산칼슘이 주로 사용되고, 상기 탄산칼슘은 석회석을 분쇄하여 만든 초미립 분말로서 석회석의 순도, 입자의 크기, 제조 방법에 따라 보통탄산칼슘, 중질탄산칼슘, 경질 탄산칼슘으로 구분되며, 그 중 중질 탄산칼슘이 폴리머 모르타르 및 콘크리트용 충전재로 주로 사용된다. In addition, as a filler in polymer mortar and concrete, calcium carbonate is mainly used, and the calcium carbonate is an ultrafine powder made by crushing limestone, and is usually calcium carbonate, heavy calcium carbonate, It is divided into hard calcium carbonate, of which heavy calcium carbonate is mainly used as a filler for polymer mortar and concrete.
상기와 같은 탄산칼슘은, 석회석 광산에서 채굴 및 파쇄, 분급과정을 거치기 때문에 자연환경의 훼손이나 파쇄 및 분급 과정에서의 분진발생으로 환경적인 문제점을 야기하고 있다. As described above, the calcium carbonate undergoes mining, crushing, and classification in limestone mines, causing environmental problems due to damage to the natural environment, dust generation during crushing, and classification.
또한, 석회석 광산의 한정적인 가행년수 또한 커다란 문제점으로 인식되고 있다.In addition, the limited running years of limestone mines are also recognized as a major problem.
한편, 폐광미는 광산 폐기물로써 현재 그 대부분은 매립처리되고 있으나 이 방법은 처리후 매립장 부지의 활용이 제한되며, 차단재의 수명에 따라 일정기간 후에 재처리 등 관리가 필요하다. On the other hand, waste tailings are mine wastes, most of which are currently landfilled, but this method is limited to the use of landfill sites after treatment, and needs to be managed after a certain period depending on the life of the barrier material.
특히, 중석선광 폐광미는 막대한 양이 적치되어 있으며, 적절한 활용방안이 강구되지 못하고 적치상태로 놓여 있어 사회문제화 되고 있다.In particular, the enormous amount of bitumen waste tailings has been accumulated, and the proper utilization method has not been devised and placed in a state of accumulation, which is becoming a social problem.
본 발명은 상기의 문제점을 개선하기 위한 그 목적은, 중석을 회수하고 남은 폐기물인 중석선광 폐광미를 폴리머 모르타르 및 콘크리트의 충전재로 활용하도록 하고, 폐광미와 탄산칼슘을 주재료로 하는 충전재를 제공하도록 하는 폐광산 광미를 충전재로 활용한 폴리머 모르타르 및 콘크리트를 제공하는데 있다.The object of the present invention is to improve the above problems, and to utilize the bituminous beneficiation waste tailings, which are the wastes left after recovering the bitumen, as a filler for polymer mortar and concrete, and to provide a filler mainly containing the waste tailings and calcium carbonate. To provide polymer mortar and concrete using waste mine tailings as filler.
상기 목적을 달성하기 위해, 폴리머 모르타르 및 콘크리트용 충전재 100중량%에 대하여 분말도 3,000㎠/g, 흡수지량 30㎖/g인 탄산칼슘 30 내지 50 중량%와 분말도 3,000㎠/g, 흡수지량 34㎖/g인 폐 광미 잔량으로 구성되는 폐광산 광미를 충전재로 활용한 폴리머 모르타르 및 콘크리트가 제공된다.In order to achieve the above object, 30 to 50% by weight of calcium carbonate having a powder degree of 3,000
이하, 본 발명의 조성물을 상세히 설명한다.Hereinafter, the composition of the present invention will be described in detail.
본 발명에서 사용되는 폐광미는, 중석 폐광산의 광미장에서 채취하여 선별과정을 거쳐 분말도 3,000㎠/g의 미립분을 사용하였다. The waste tailings used in the present invention were collected from the tailings tailings of the bituminous waste mines, followed by a screening process, and the fine powder having a powder degree of 3,000
잘 알려진 바와 같이 충전재는, 폴리머 모르타르 및 콘크리트 제조시 수지의 증량, 성형성 개선, 내마모성 및 내열성의 향상, 수축의 저감 및 균열 방지 등 각종 성능향상을 목적으로 사용되어지는 미립자 상의 골재로서 수지의 흡착량이 크지 않고, 성형물의 외관이나 제물성을 저하 시키지 않아야 하며, 비중이 크지 않고, 입자의 형상 및 크기가 적당해야 한다. As is well known, fillers adsorb the resin as aggregates on fine particles, which are used for the purpose of increasing the performance of polymer mortar and concrete, improving moldability, improving wear resistance and heat resistance, reducing shrinkage, and preventing cracking. The amount should not be large, the appearance or product properties of the molding should not be reduced, the specific gravity should not be large, and the shape and size of the particles should be appropriate.
통상적으로 사용되는 중질탄산칼슘은, 고경도의 결정질 석회석을 분쇄한 후 입자들을 분급하여 제조하며, CaCO3(95-98%)의 고순도 원석을 사용하여 평균입경 18㎛(1.0-60㎛)로 가공한 미세한 분말이며, 수지의 흡착량을 평가하는 지표인 흡수지량이 30정도이다. Heavy calcium carbonate is commonly used in, and prepared by grinding and then classifying the crystalline limestone of high hardness particles, with an average particle diameter 18㎛ (1.0-60㎛) by using highly pure ore of CaCO 3 (95-98%) It is a fine powder processed and the absorption index which is an index which evaluates the adsorption amount of resin is about 30.
그리고, 본 발명의 폐광미는, 선별과정을 거쳐 얻어지는 평균입경 19㎛(10-70㎛)의 미립분으로 흡수지량이 34정도로 이는 통상적인 중질탄산칼슘과 거의 유사한 수치이다. In addition, the waste tailings of the present invention is a fine particle having an average particle diameter of 19 μm (10-70 μm) obtained through the screening process, and its absorption index is about 34, which is almost similar to that of conventional heavy calcium carbonate.
그 결과는, 도면 1에 나타낸 바와 같으며, 이에따르면 흡수지량 뿐만 아니라 입자의 형상 및 비중 또한 유사한 것을 알수 있다. The results are as shown in Figure 1, whereby it can be seen that not only the absorbing amount but also the shape and specific gravity of the particles are similar.
본 발명의 폴리머 모르타르 및 콘크리트의 원료로서 사용된 결합재와 충전재의 성질은 다음과 같다.The properties of the binder and filler used as raw materials of the polymer mortar and concrete of the present invention are as follows.
표1은 본 실험에 사용된 수지의 성질을 나타낸 것이다. Table 1 shows the properties of the resin used in this experiment.
표 2는 중질 탄산칼슘과 폐광미의 화학조성이다.Table 2 shows the chemical composition of heavy calcium carbonate and waste tailings.
[실시예 1]Example 1
충전재가 중질탄산칼슘과 폐광미로 구성되며, 충전재/(결합재+충전재) 비를 30-60%로 하고, 모르타르의 경우 잔골재를, 콘크리트의 경우 잔골재와 굵은 골재를 더하여 구성될 수 있다.The filler is composed of heavy calcium carbonate and waste tailings, the filler / (binder + filler) ratio of 30-60%, the fine aggregate in the mortar, the fine aggregate and coarse aggregate in the concrete may be configured.
이와 같이 조성되는 충전재는 흡수율 1% 미만으로 건조시켜 골재와 혼합한 후, 촉진제로서 디메틸파라톨루이딘(DMT), 개시제로써 벤조일 퍼옥사이드(BPO)를 사용한 불포화 폴리에스테르 수지 결합재와 혼련하여 폴리머 모르타르 혹은 폴리머 콘크리트로 제조된다. The filler thus prepared is dried to less than 1% of water absorption, mixed with aggregate, and then kneaded with an unsaturated polyester resin binder using dimethyl paratoluidine (DMT) as an accelerator and benzoyl peroxide (BPO) as an initiator to form a polymer mortar or polymer. It is made of concrete.
표 3은 실험에 사용된 배합조건을 나타낸 것이다.Table 3 shows the mixing conditions used in the experiment.

중질탄산칼슘 및 폐광미를 충전재로 사용한 폴리머 모르타르의 사용가능시간 측정.Measurement of the usable time of polymer mortar using heavy calcium carbonate and waste tailings as filler.
사용가능시간이란 결합재에 개시제를 첨가한 직후부터 액상 수지가 경화반응을 개시하고 결합재 및 폴리에스테르 모르타르가 유동성을 상실해 사용이 불가능한 때까지의 시간을 말하며, KS F 2484(폴리에스테르 레진 콘크리트의 사용가능 시간 측정 방법)의 4.3(감촉법)에 따라 폴리에스테르 모르타르의 사용가능 시간을 측정하였다. 이때의 측정조건은 20±2℃, 60%(RH)였다. The usable time is the time from the addition of the initiator to the binder until the liquid resin starts the curing reaction and the binder and the polyester mortar lose their fluidity and cannot be used. KS F 2484 (Use of polyester resin concrete) The usable time of the polyester mortar was measured according to 4.3 (feel method) of the available time measurement method). The measurement conditions at this time were 20 +/- 2 degreeC and 60% (RH).
그 결과는 도2와 같다. The result is shown in FIG.
상기 실험예 1에서 알 수 있는 바와 같이, 폐광미 치환율이 증가함에 따라 폐광미 속에 존재하는 미량의 중금속성분에 의해 사용가능 시간은 길어지고 있으나 상기 실시예 1에서 폴리머 모르타르의 사용가능시간은 약 20∼60min 범위에 있었으며, 이는 일반적인 불포화 폴리에스테르 수지의 경화시스템인 코발트계 촉진제 및 메틸에틸 케톤퍼옥사이드를 개시제로서 사용한 경우보다 약 1.5배 빠른 경화속도로서, DMT-BPO 시스템을 이용함으로써 폐광미 중의 미량중금속에 의한 경화지연을 개선할 수 있음을 알 수 있다.As can be seen in Experimental Example 1, as the waste tailings substitution rate is increased, the usable time is increased by the trace heavy metal components present in the waste tailings, but the usable time of the polymer mortar in Example 1 is about 20 It was in the range of ˜60 min, which is about 1.5 times faster than the cobalt accelerator and methylethyl ketone peroxide, which are curing systems of general unsaturated polyester resins, as a initiator. It can be seen that the curing delay due to heavy metals can be improved.

중질탄산칼슘 및 폐광미를 충전재로 사용한 폴리머 모르타르의 휨강도 및 압축강도측정.Measurement of Flexural Strength and Compressive Strength of Polymer Mortar Using Heavy Calcium Carbonate and Waste Tailings as Fillers
충전재/(충전재+결합재) 비 30-50%로 하여 KS F 2419에 의거해서 폴리에스테르 모르타르 공시체를 40×40×160㎜의 크기로 각각 3개씩 제작한 후 20±2℃, 60%(RH)의 조건에서 7일간 양생하였다. According to KS F 2419, three polyester mortar specimens were prepared in the size of 40 × 40 × 160mm according to KS F 2419, and then each 20 ± 2 ℃ and 60% (RH). Cured for 7 days under the conditions of.
KS F 2482(폴리에스테르 레진 콘크리트의 휨강도 시험방법) 및 KS F 2483(보의 절편에 의한 폴리에스테르 레진 콘크리트의 압축강도 시험방법)에 의거하여 휨강도 및 압축강도를 측정하였으며, 그 결과를 도3 및 도4에 나타내었다. The flexural strength and the compressive strength were measured according to KS F 2482 (Testing method of bending strength of polyester resin concrete) and KS F 2483 (Testing method of compressive strength of polyester resin concrete by beam section). 4 is shown.
실험예 2의 결과를 살펴보면, 충전재/(결합재+충전재) 비가 50%에서 폐광미를 충전재로 혼입한 폴리머 모르타르의 휨강도 및 압축강도가 중질탄산칼슘을 사용한 경우보다 약 1.2배 높게 측정되었다. In the results of Experimental Example 2, the flexural strength and the compressive strength of the polymer mortar incorporating the waste tailings as a filler at 50% of the filler / (binder + filler) ratio was measured about 1.2 times higher than when using heavy calcium carbonate.
실험예 2의 결과에 나타낸 바와 같이, 충전재/(결합재+충전재)비 30-50%의 이내의 범위에서 충전재로 폐광미가 중질탄산칼슘을 대체할 수 있음을 확인하였다. As shown in the results of Experimental Example 2, it was confirmed that the waste tailings can replace the heavy calcium carbonate with the filler within the range of 30-50% filler / (binder + filler) ratio.
[실시예 2]Example 2
상기 실시예 1의 실험결과를 토대로 강도 성상이 높게 측정된 충전재/(결합재+충전재) 비 50%를 대상으로 폴리머 모르타르 및 콘크리트 제조시 일반적인 충전재로 사용되는 중질탄산칼슘(100중량%)의 30-100%를 폐광미로 치환하여 구성되며, 이외의 실험 재료 및 조건은 실시예 1과 같다. 30- of heavy calcium carbonate (100% by weight) used as a general filler in the production of polymer mortar and concrete, based on a 50% filler / (binder + filler) ratio with high strength properties based on the experimental results of Example 1 It is configured by replacing 100% with the waste tailings, and other experimental materials and conditions are the same as in Example 1.
[실험예 3]Experimental Example 3
충전재/(결합재+충전재)비 50% 폴리머 모르타르의 휨강도 및 압축강도 측정.Determination of flexural and compressive strength of 50% polymer mortar with filler / (binder + filler) ratio.
KS F 2419에 의거해서 폴리에스테르 모르타르공시체를 40×40×160㎜의 크기로 각각 3개씩 제작한 후 20±2℃, 60%(RH)의 조건에서 7일간 양생하였다. According to KS F 2419, three polyester mortar specimens were prepared, each having a size of 40 × 40 × 160 mm, and then cured under conditions of 20 ± 2 ° C. and 60% (RH) for 7 days.
KS F 2482(폴리에스테르 레진 콘크리트의 휨강도 시험방법) 및 KS F 2483(보의 절편에 의한 폴리에스테르 레진 콘크리트의 압축강도 시험방법)에 의거하여 휨강도 및 압축강도를 측정하였으며, 그 결과를 하기 도5과 도6에 나타내었다.The flexural strength and the compressive strength were measured according to KS F 2482 (Testing method of flexural strength of polyester resin concrete) and KS F 2483 (Testing method of compressive strength of polyester resin concrete by beam section). And shown in FIG.
상기 실험예3에서 알 수 있는 바와 같이 본 발명에 따른 충전재를 사용하여 폴리머 모르타르의 휨강도 및 압축강도가 폐광미 치환율이 증가함에 따라 증가하며, 충전재를 폐광미로 전량 치환했을 때의 휨강도 및 압축강도는 1-2MPa의 강도 감소가 관찰되었다. As can be seen in Experiment 3, the bending strength and the compressive strength of the polymer mortar using the filler according to the present invention increases as the waste tailings substitution rate increases, and the bending strength and the compressive strength when the filler is completely replaced by the waste tailings are A decrease in strength of 1-2 MPa was observed.
이러한 강도 감소의 이유는 충전재의 흡수지량과 입형 그리고 수지의 경화반응 지연작용의 차이에서 비롯되는 것으로 사료된다. The reason for the decrease in strength may be due to the difference between the absorbing amount of the filler, the shape of the filler, and the delaying action of the resin.
그러나, 기존의 충전재로 사용되고 있는 중질탄산칼슘의 30내지 50중량%를 분말도 3,000㎠/g-6,000㎠/g의 폐광미로 치환하여 사용함으로써 폴리머 모르타르를 제조할 경우 휨강도 및 압축강도 발현의 면에서 볼 때 보다 높은 강도를 나타냄을 확인 할 수 있었다. However, when the polymer mortar is manufactured by replacing 30 to 50% by weight of heavy calcium carbonate, which is used as a conventional filler, with waste tailings of 3,000
본 발명에 의하면 폴리머 모르타르 및 콘크리트 제조시 중질탄산칼슘의 30내지 50중량%를 폐광미로 치환하여 사용함으로써 중질탄산칼슘만을 사용한 경우보다 좀 더 높은 휨강도 및 압축강도를 나타내면서도 강도가 높고 보다 경제적이어서 제조 원가를 절감할 수 있다. According to the present invention, by using 30 to 50% by weight of heavy calcium carbonate by replacing waste tailings in the manufacture of polymer mortar and concrete, it exhibits higher flexural strength and compressive strength than that of heavy calcium carbonate alone, but is high in strength and more economical. Cost can be reduced.
또한, 중질탄산칼슘 자체를 폐광미와 같은 폐기물로 대체 사용함으로써 자원절약과 더불어 환경오염을 방지하는 등의 효과가 있다.In addition, by using heavy calcium carbonate itself as waste such as waste tailings, there is an effect such as saving resources and preventing environmental pollution.
