본 발명은 저회와 유황폴리머를 함유한 경량 콘크리트 패널 및 그 제조방법법에 관한 것으로, 더욱 상세하게는 플라이애쉬를 포함하지 않고 저회만을 이용하는 저회와 유황폴리머를 함유한 경량 콘크리트 패널 및 그 제조방법에 관한 것이다.The present invention relates to a lightweight concrete panel containing bottom ash and sulfur polymer and a manufacturing method thereof, and more particularly, to a lightweight concrete panel containing bottom ash and sulfur polymer using only bottom ash without containing fly ash and a manufacturing method thereof. it's about

일반적으로 건축물의 외벽재는 콘크리트를 사용하였다. 하지만 콘크리트의 경우 중량이고, 양생을 하기 위한 기간이 소요되며 인장 및 휨 강도가 취약한 단점이 있다.In general, concrete is used as the exterior wall material of buildings. However, in the case of concrete, there are disadvantages in that it is heavy, requires a period for curing, and has weak tensile and bending strength.

이러한 단점을 극복하기 위하여 외벽을 시공하는 방법이 모듈러 방식으로 전환되고 있다. 현재 모듈러 방식으로 사용되는 외벽은 샌드위치 패널이 주로 사용되고 있다.In order to overcome these disadvantages, the method of constructing the outer wall is being converted to a modular method. Sandwich panels are mainly used for exterior walls that are currently used in a modular manner.

하지만 샌드위치패널은 공기가 단축되고 내외부를 마감할 필요가 없는 장점이 있지만 얇은 강판으로 구성되어 강도가 약하고 내부의 충전제로 인하여 화재의 발생시 유독가스가 발생함에 따라 인명피해를 일으키는 문제점이 있다.However, the sandwich panel has the advantage of shortening the air and not needing to finish the inside and outside, but has a problem of causing human damage as toxic gas is generated in the event of a fire due to the weak strength due to the thin steel plate.

이러한 샌드위치패널과 콘크리트의 단점을 극복하기 위하여 경량 콘크리트 패널이 개발되었다.In order to overcome the disadvantages of these sandwich panels and concrete, lightweight concrete panels have been developed.

경량 콘크리트 패널의 일예가 국내특허공개2006-0086005호(이하, '선행기술문헌 1'이라 함)에 개시되어 있다.An example of a lightweight concrete panel is disclosed in Korean Patent Publication No. 2006-0086005 (hereinafter referred to as 'Prior Art Document 1').

도 1은 선행기술문헌 1에 개시된 종래의 경량 콘크리트 패널의 단면상태도이다.1 is a cross-sectional state diagram of a conventional lightweight concrete panel disclosed in Prior Art Document 1.

선행기술문헌 1에 개시된 종래의 경량 콘크리트 패널은 혼합물(21)로 형성이루어지고, 내부에 휨 강성을 보강하도록 길이방향으로 중간에 와이어 메쉬 철망(22)이 배치되고, 서로 끼우기 용이하도록 일측에는 외측방향으로 도출형성된 끼움돌기(23)가 타측에는 내측방향으로 요입된 끼움홈(24)이 형성된다. 상기 경량 콘크리트 패널의 혼합물(21)은 체적비 5-7%의 5mm 이하인 저회, 체적비 8-11%의 시멘트, 체적비 2-4%인 플라이애쉬 체적비 11-17%인 물, 체적비 65-72%인 EPS 입자로 혼합된다.The conventional lightweight concrete panel disclosed in Prior Art Document 1 is formed of a mixture 21, and a wire mesh wire mesh 22 is disposed in the middle in the longitudinal direction to reinforce the bending stiffness inside, and the outer side on one side to facilitate insertion into each other The fitting protrusion 23 formed in the direction is formed with a fitting groove 24 concave inward on the other side. The mixture 21 of the lightweight concrete panel is bottom ash having a volume ratio of 5-7% of 5 mm or less, cement having a volume ratio of 8-11%, fly ash having a volume ratio of 2-4%, water having a volume ratio of 11-17%, and volume ratio of 65-72% mixed with EPS particles.

하지만 경량 콘크리트에 플라이 애쉬를 이용함에 따라 일반 콘크리트에 비해 응결시간이 늦어지므로 콘크리트가 사용되는 구조물의 종류와 물-시멘트비 등에 따라 거푸집 제거시간을 조절하거나 경화촉진제 등을 함께 사용해야 한다.However, as fly ash is used for lightweight concrete, setting time is delayed compared to general concrete, so it is necessary to adjust the formwork removal time or use a hardening accelerator according to the type of structure in which concrete is used and the water-cement ratio.

또한 플라이 애쉬는 그 자체의 수경성이 거의 없으나 공기중의 수분과 반응하여 응집되어 가압상태에서 고결되는 현상이 있어 취급이 곤란하며 이를 막기 위해서는 공기의 습도를 낮추든지 플라이 애쉬를 미리 물과 혼합하여 슬러리 상태로 대량 저장하고 교반하면서 계량하는 등 별도의 조치가 필요하다.In addition, fly ash itself has almost no hydraulic properties, but it reacts with moisture in the air to coagulate and solidifies under pressure, making it difficult to handle. Separate measures are required, such as mass storage and weighing while stirring.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 플라이애쉬를 포함하지 않고 저회만을 이용하는 저회와 유황폴리머를 함유한 경량 콘크리트 패널 및 그 제조방법을 제공하는 데 목적이 있다.Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a lightweight concrete panel containing bottom ash and sulfur polymer using only bottom ash without containing fly ash and a manufacturing method thereof.

여기서 상기 유동화제는 폴리카본계인 것이 바람직하다.Here, the glidant is preferably a polycarbon type.

본 발명에 따른 저회와 유황폴리머를 함유한 경량 콘크리트 패널 및 그 제조방법은 단위체적인 1m3 기준 상기 유황폴리머를 포함하는 시멘트가 330 내지 450 kg을 포함함에 따라 균열발생을 최소화하고 적정강도를 유지할 수 있다.The lightweight concrete panel containing bottom ash and sulfur polymer and its manufacturing method according to the present invention can minimize cracking and maintain appropriate strength as the cement containing the sulfur polymer contains 330 to 450 kg per unit volume of 1 m 3 . there is.

또한 본 발명에 따른 저회와 유황폴리머를 함유한 경량 콘크리트 패널 및 그 제조방법은 잔골재비가 0.4 내지 1.2 이므로 단위중량당 강도를 향상시킬 수 있다.In addition, since the lightweight concrete panel containing bottom ash and sulfur polymer and its manufacturing method according to the present invention have a fine aggregate ratio of 0.4 to 1.2, strength per unit weight can be improved.

아울러 본 발명에 따른 저회와 유황폴리머를 함유한 경량 콘크리트 패널 및 그 제조방법은 배합수비는 30 중량% 내지 50 중량%이므로 강도를 강도를 떨어뜨리지 않으면서 작업성도 동시에 향상된다.In addition, since the lightweight concrete panel containing bottom ash and sulfur polymer and its manufacturing method according to the present invention have a mixing ratio of 30% to 50% by weight, workability is simultaneously improved without reducing strength.

또한 본 발명에 따른 저회와 유황폴리머를 함유한 경량 콘크리트 패널 및 그 제조방법은 유황폴리머의 비율이 10 중량% 내지 30 중량% 이므로 중량의 증가에 따른 경도의 저하를 최소화 할 수 있다In addition, in the lightweight concrete panel containing bottom ash and sulfur polymer and its manufacturing method according to the present invention, the ratio of sulfur polymer is 10% to 30% by weight, so the decrease in hardness due to the increase in weight can be minimized.

도 1은 선행기술문헌 1에 개시된 종래의 경량 콘크리트 패널의 단면상태도이다.
도 2는 본 발명에 따른 저회와 유황폴리머를 함유한 경량 콘크리트 패널의 제조방법을 나타내는 플로우챠트이다.
1 is a cross-sectional state diagram of a conventional lightweight concrete panel disclosed in Prior Art Document 1.
Figure 2 is a flow chart showing a method of manufacturing a lightweight concrete panel containing bottom ash and sulfur polymer according to the present invention.

이하, 본 발명에 따른 저회와 유황폴리머를 함유한 경량 콘크리트 패널 및 그 제조방법을 첨부도면을 참조하여 설명하면 다음과 같다.Hereinafter, a lightweight concrete panel containing bottom ash and sulfur polymer and a manufacturing method thereof according to the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 저회와 유황폴리머를 함유한 경량 콘크리트 패널의 제조방법을 나타내는 플로우챠트이다.Figure 2 is a flow chart showing a method of manufacturing a lightweight concrete panel containing bottom ash and sulfur polymer according to the present invention.

본 발명의 일실시예에 따른 저회와 유황폴리머를 함유한 경량 콘크리트 패널은 유황폴리머를 포함하는 시멘트와 저회가 혼합된 혼합물로 이루어진다.A lightweight concrete panel containing bottom ash and sulfur polymer according to an embodiment of the present invention is made of a mixture of cement and bottom ash containing sulfur polymer.

상기 시멘트는 유황폴리머를 포함한 시멘트로서 콘크리트 단위중량인 1 m3 에 330 kg 내지 450 kg이 포함되는 것이 바람직하다.The cement is a cement containing a sulfur polymer, and it is preferable that 330 kg to 450 kg is included in 1 m 3 of concrete unit weight.

여기서 유황풀리머는 정유부산물로서 콘크리트의 경화과정에서 폴리머 반응이 진행되며 조기에 고강도를 나타내어 부재 단면을 작게할 수 있어 경량화가 가능한 재료이다. 아울러 콘크리트 내부에서 콘크리트의 미세공극을 충진하여 콘크리트의 잔골제를 결합시켜주는 본딩제 기능을 함에 따라 내구성이 우수하고 미장 마감재로서도 사용이 가능하다.Here, sulfur polymer is a by-product of oil refining, and a polymer reaction proceeds during the hardening process of concrete. In addition, it has excellent durability and can be used as a plastering finishing material as it functions as a bonding agent that binds the fine aggregate of concrete by filling the microvoids of concrete inside the concrete.

상기 시멘트는 곤크리트 단위중량인 1 m3 에 330 kg 미만일 경우 강도가 저하되고 450 kg을 초과할 경우 건조수축 및 소성수추 균열이 발생함에 따라 곤크리트 단위중량인 1 m3 에 330 kg 내지 450 kg을 포함하는 것이 바람직하다.When the cement is less than 330 kg per 1 m 3 , which is the unit weight of goncrete, the strength is lowered, and when it exceeds 450 kg, drying shrinkage and cracks occur, so that 330 kg to 450 kg per 1 m 3 , which is 1 m 3 , unit weight of goncrete It is preferable to include

상기 시멘트에 포함되는 유황풀리머는 유황폴리머를 포함한 시멘트 중량의 10% 미만일 경우 강도가 저하되고 30%를 초과할 경우는 경량화의 의미가 없어지므로 유황풀리머는 유황폴리머를 포함한 중량의 10% 내지 30% 인것이 바람직하다.When the weight of the sulfur polymer included in the cement is less than 10% of the weight of the cement including the sulfur polymer, the strength is lowered, and when it exceeds 30%, the meaning of weight reduction is lost. It is desirable that

또한 본 발명에 따른 경량 콘크리트는 잔골재로 저회를 사용한다.In addition, the lightweight concrete according to the present invention uses bottom ash as a fine aggregate.

상기 저회(Bottom Ash)는 화력발전소에서 발생되는 산업부산물로 바다에 매립되어 바다물에 용출되므로 환경파괴의 원인이 되고 있다.The bottom ash is an industrial by-product generated from thermal power plants and is buried in the sea and eluted into sea water, causing environmental destruction.

따라서 본 발명에 따른 경량 콘크리는 산업부산물로 발생되는 저회를 잔골재로 사용한다. 여기서 저회를 잔골재로 사용할 경우 다공성으로 인해 경량화가 가능하며 특히 EPS 볼을 추가하므로 더욱 경량화가 가능하다.Therefore, the lightweight concrete according to the present invention uses bottom ash generated as an industrial by-product as fine aggregate. Here, when bottom ash is used as fine aggregate, it is possible to reduce weight due to its porosity, and in particular, it is possible to reduce weight further by adding EPS balls.

본 발명에 따른 경량 콘크리트의 잔골재비(저회/시멘트)는 0.4 미만일 경우 경량성 구현이 미미하고 1.2를 초과할 경우 강도의 저하되므로 잔골재비는 0.4 내지 1.2 인 것이 바람직하다.If the fine aggregate ratio (bottom ash/cement) of the lightweight concrete according to the present invention is less than 0.4, the implementation of lightness is insignificant, and if it exceeds 1.2, the strength is reduced. Therefore, the fine aggregate ratio is preferably 0.4 to 1.2.

또한 본 발명에 따른 배합수비(물/시멘트)는 콘크리트를 타설하고 성형하기 위하여 30% 미만일 경우 작업성이 불량하며 50%를 초과할 경우 강도저하가 일어나므로 배합수비는 30% 내지 50%인 것이 바람직하다.In addition, the mixing ratio (water/cement) according to the present invention is poor in workability when it is less than 30% for pouring and molding concrete, and strength decreases when it exceeds 50%, so the mixing ratio is 30% to 50%. desirable.

본 발명의 일실시예에 따른 저회와 유황폴리머를 함유한 경량 콘크리트 패널의 제조방법을 설명하면 다음과 같다.A method for manufacturing a lightweight concrete panel containing bottom ash and a sulfur polymer according to an embodiment of the present invention will be described as follows.

도 2에 도시된 바와 같이 시멘트와 유황폴리머를 혼합용기에 투입하는 시멘트 투입단계(S100), 상기 혼합용기에 물을 투입한 후 교반하는 물 혼합단계(S120), 상기 혼합용기에 유동화제를 투입한 후 교반하는 유동화제 혼합단계(130), 상기 혼합용기에 저회를 투입한 후 교반하는 저회 혼합단계(S140), 상기 혼합용기에 EPS 볼을 혼합한 후 교반하는 EPS 볼 혼합단계(S150) 및 상기 혼합용기의 혼합물을 형틀에 부어 경량 콘크리트 패널을 성형하는 패널 성형단계(S160)을 포함한다. As shown in FIG. 2, a cement input step (S100) of introducing cement and sulfur polymer into a mixing container, a water mixing step (S120) of adding water to the mixing container and stirring (S120), and adding a fluidizing agent to the mixing container. After stirring, a glidant mixing step (130), a bottom ash mixing step (S140) in which bottom ash is added to the mixing container and then stirred, an EPS ball mixing step (S150) in which EPS balls are mixed in the mixing container and then stirred, and and a panel molding step (S160) of molding a lightweight concrete panel by pouring the mixture from the mixing vessel into a mold.

상기 시멘트 투입단계(S100)는 시멘트와 유황폴리머를 혼합용기에 투입하는 단계로서 시멘트와 유황폴리머는 유황폴리머를 포함한 시멘트 중량의 10% 내지 30%이다. 여기서 미리 혼합한 후 혼합용기에 투입할 수 있고 순차적으로 유황폴리머와 시멘트를 투입할 수 있다. 여기서 상기 혼합용기는 투입물을 혼합할 수 있도록 회전이 가능하거나 교반기에 의해서 교반이 가능하도록 구비되어야 한다.The cement input step (S100) is a step of putting cement and sulfur polymer into a mixing container, and the cement and sulfur polymer are 10% to 30% of the cement weight including the sulfur polymer. Here, after mixing in advance, it can be put into a mixing container, and sulfur polymer and cement can be added sequentially. Here, the mixing container should be provided so as to be able to rotate or be stirred by a stirrer so as to mix the inputs.

상기 물 혼합단계(S120)는 혼합용기에 물을 투입한 후 교반하는 단계로서 혼합분체 중량의 30 내지 40%를 투입하여 교반한다. 여기서 투입 후 교반시간은 통상 30초가 20 rpm으로 혼합용기과 회전하지만 필요에 따라 회전속도및 시간을 조절할 수 있음은 물론이다.The water mixing step (S120) is a step of stirring after adding water to the mixing container, and 30 to 40% of the weight of the mixed powder is added and stirred. Here, the stirring time after addition is usually 30 seconds and the mixing container rotates at 20 rpm, but the rotation speed and time can be adjusted as needed, of course.

상기 유동화제 혼합단계(130)는 혼합용기에 유동화제를 투입한 후 교반하는 단계로서 유동화제는 폴리카본계를 사용하는 것이 바람직하다. 상기 유동화제로 사용되는 폴리카본계의 유동화제는 시간에 따른 유동성의 저하가 훨씬 적기 때문에 현장에서의 작업 지연에 따른 유동성 저하를 방지할 수 있는 장점이 있다. 상기 유동화제는 유황폴리머를 포함한 시멘트 중량의 1% 내지 2% 를 혼합용기에 투입한 후 통상 30초간 20 rpm으로 혼합용기를 회전시키지만 필요에 따라 회전속도및 시간을 조절할 수 있음은 물론이다.The fluidizing agent mixing step 130 is a step of stirring after adding a fluidizing agent to a mixing container, and it is preferable to use a polycarbon-based fluidizing agent. The polycarbon-based glidant used as the glidant has the advantage of being able to prevent deterioration in fluidity due to delay in work in the field because the decrease in fluidity over time is much less. After adding 1% to 2% of the weight of the cement containing the sulfur polymer into the mixing container, the fluidizing agent is usually rotated at 20 rpm for 30 seconds, but the rotation speed and time can be adjusted as needed.

상기 저회 혼합단계(S140)는 혼합용기에 저회를 투입한 후 교반하는 단계로서 저회를 혼합용기에 투입한 후 1분간 40 rpm으로 혼합용기를 회전하면서 교반한다. 상기 혼합용기가 통상 1분간 40 rpm으로 회전하지만 필요에 따라 회전속도및 시간을 조절할 수 있음은 물론이다. 여기서 저회는 혼합용기의 벽면에 부착될 수 있으므로 혼합용기를 정지시킨 상태에서 스크레이퍼를 통해 혼합용기의 내벽을 긁어서 혼합물이 혼합용기의 하부로 떨어지도록 할 수 있음은 물론이다.The bottom ash mixing step (S140) is a step of stirring after putting the bottom ash into the mixing container. After putting the bottom ash into the mixing container, the mixing container is stirred while rotating at 40 rpm for 1 minute. Although the mixing container is usually rotated at 40 rpm for 1 minute, it is of course possible to adjust the rotation speed and time as needed. Here, since the bottom ash may adhere to the wall surface of the mixing vessel, it is of course possible to scrape the inner wall of the mixing vessel through a scraper in a state in which the mixing vessel is stopped so that the mixture falls to the lower portion of the mixing vessel.

상기 EPS 볼 혼합단계(S150)는 혼합용기에 EPS 볼을 혼합한 후 교반하는 단계로서 EPS 볼을 투입한 후 회전용기를 1분간 40rpm으로 회전시켜 EPS 볼이 혼합물의 내부에 균일하게 분산될 수 있도록 한다. The EPS ball mixing step (S150) is a step of mixing the EPS balls in a mixing container and then stirring them. After putting the EPS balls, the rotating container is rotated at 40 rpm for 1 minute so that the EPS balls can be uniformly dispersed inside the mixture. do.

상기 패널 성형단계(S160)상기 혼합용기의 혼합물을 형틀에 부어 경량 콘크리트 패널을 성형하는 단계이다. 여기서 상기 EPS 볼은 혼합용기가 회전하지 않으면 비중이 현저히 작기 때문에 상부로 부상함에 따라 혼합용기의 회전을 멈춤과 동시에 형틀에 부어 경량 콘크리트 패널을 성형해야 한다. 여기서 형틀에 부어진 혼합물은 양생을 통해 응고가 된 후 형틀에서 제거한다. 여기서 상기 형틀에 부어진 콘크리트 혼합물의 양생기간을 줄이기 위하여 온도를 높이거나 기류를 일으키는 다양한 방법을 사용할 수 있음은 물론이다.The panel molding step (S160) is a step of molding a lightweight concrete panel by pouring the mixture from the mixing container into a mold. Here, since the EPS ball has a significantly low specific gravity if the mixing container does not rotate, as it rises to the top, the rotation of the mixing container must be stopped and poured into the mold to form a lightweight concrete panel. Here, the mixture poured into the mold is removed from the mold after being solidified through curing. Here, of course, various methods of increasing the temperature or generating air flow can be used to reduce the curing period of the concrete mixture poured into the mold.

본 발명에서 혼합용기를 회전하여 콘크리트 혼합물을 혼합하거나, 교반기를 이용하여 혼합물을 교반하는 것은 필요에 따라 선택적을 사용할 수 있음은 물론이다.Of course, in the present invention, mixing the concrete mixture by rotating the mixing vessel or stirring the mixture using an agitator can be selectively used as needed.
