이와 같은 탄성 투수콘크리트를 적용하는 경우에는 투수콘크리트에 탄력성이 부여되어 휨인성과 동결융해작용에 대한 내구성이 증대되고, 독립공극이 감소되고 연속공극이 증가됨에 따라 투수성과 압축강도가 현저하게 향상되는 한편, 산업폐기물을 재활용할 수 있음에 따라 환경오염을 줄일 수 있고 생산비용을 절감시킬 수 있게 된다.In the case of applying such elastic permeable concrete, elasticity is imparted to the permeable concrete to increase the flexural toughness and durability against freezing and thawing, and the permeability and the compressive strength are remarkably improved as the independent voids are reduced and the continuous pores are increased. On the other hand, the industrial waste can be recycled to reduce environmental pollution and to reduce production costs.
Description
본 발명은 탄성을 갖는 투수콘크리트와 그 제조방법 및 그 시공방법에 관한 것으로, 특히 자전거도로, 보도 및 광장 등 하중을 크게 받지 않는 경도로(輕道路)등에 사용되는 포장체의 재료로서 투수성과 탄력성을 갖고 동시에 고인성 및 내구성을 발휘하는 탄성투수콘크리트 및 그 제조방법에 관한 것이다.The present invention relates to an elastic permeable concrete, a method for manufacturing the same and a method for constructing the same. Particularly, the water permeability and elasticity of a pavement body used in a roadway such as a bicycle road, a sidewalk, a square, and the like, which are not subjected to a large load. It relates to an elastic permeable concrete having a high toughness and durability at the same time and a manufacturing method thereof.
또한, 본 발명은 이와 같이 제조된 탄성투수콘크리트를 시공하는 방법에 관한 것이다.In addition, the present invention relates to a method for constructing the elastic permeable concrete prepared as described above.
일반적으로 투수성을 갖는 포장체로는 크게 투수콘크리트와 투수아스콘이 있으나 이들은 많은 문제점을 가지고 있다.In general, the permeability of the package is largely pitched concrete and pitched ascon, but these have a number of problems.
종래 일반적인 투수성 콘크리트포장체는 제1도에 도시된 바와 같이, 콘크리트의 혼합시에 잔골재를 사용하지 않고 굵은 골재(10)와 시멘트(20)만을 사용하여 단순히 콘크리트 내부에 공극(30)을 형성시키므로써 투수성을 갖도록 한 구조로 이루어진다.Conventional water-permeable concrete pavement, as shown in FIG. 1, by using only the
그러나, 이와 같은 종래의 투수성 콘크리트에서는 잔골재를 사용하지 않고 굵은 골재만을 사용하므로써 불필요한 독립된 공극이 많이 형성되기 때문에 압축강도를 충분히 발휘하지 못하게 되며, 또한 휨인성이 작아 휨강도가 저하되는 문제점이 있고, 온도응력과 건조수축에 따른 균열발생을 억제할 수 없기 때문에 콘크리트 포장체에 균열이 쉽게 발생된다는 문제가 있다.However, in such a conventional permeable concrete, by using only coarse aggregates without using fine aggregates, since many unnecessary independent voids are formed, the compressive strength is not sufficiently exhibited, and also the flexural toughness is reduced, and thus the flexural strength is deteriorated. There is a problem that cracks are easily generated in the concrete pavement because it is not possible to suppress cracking caused by temperature stress and drying shrinkage.
또한, 종래의 투수성 콘크리트는 물과의 접촉이 빈번하게 이루어지는 경우에 콘크리트 내부로 깊숙히 침투된 수분이 배수되지 못하고 독립된 공극내에 잔류되는데, 이와 같은 상태에서 외기의 온도가 저하되는 경우에는 동결융해작용에 의하여 내구성이 크게 떨어진다는 문제가 있다.In addition, the water-permeable concrete in the prior art when the water is frequently contacted with water, the water deeply penetrated into the concrete is not drained and remains in the independent pores, in this case freezing and thawing action when the temperature of the outside air is lowered There is a problem that the durability is greatly reduced.
또한, 이와 같은 종래의 투수성 콘크리트에서는 콘크리트속의 굵은골재(10) 상호간의 결합이 단순히 시멘트(20) 접착에만 의존하기 때문에 생산단가가 비싸고 역학적 특성이 좋지 못하며 내구성이 현저히 저하된다는 문제점이 있으며, 비탄성이므로 보도나 광장 등에 포장되는 경우에 사용시 통행인의 보행감이 딱딱할 뿐만 아니라 자전거의 통행에 있어서도 사용성이 좋지 못하였다.In addition, in such a conventional permeable concrete, the
한편, 종래 투수성 포장체의 다른 예인 투수아스콘은 내구성이 극히 불량하고, 고온에 약하기 때문에 이물질이 유입되는 경우, 또는 여름철과 같이 노면의 온도가 상승되는 경우에 아스팔트의 유동성이 증가되면서 투수공이 메워짐에 따라 시공 후 일정 기간이 경과되면 그 투수성이 현저히 저하된다는 문제점이 있다.On the other hand, the pitcher ascon, another example of a conventional permeable package is extremely poor in durability and weak to high temperatures, so that when the foreign matter flows in, or when the road surface temperature increases, such as summer, the permeability is filled According to the load there is a problem that the water permeability is significantly reduced after a certain period of time after construction.
본 발명은 이와 같은 종래의 투수성 포장체가 갖는 문제점을 해결하기 위한 것으로, 그 목적은 탄력성을 가지게 하여 휨인성과 동결융해작용에 대한 내구성을 증대시킬 수 있도록 하고, 독립공극을 줄이고 연속공극을 증가시켜 투수성과 압축강도를 향상시킬 수 있도록 하는 한편, 산업폐기물의 재활용을 통하여 환경오염을 줄일 수 있도록 하고, 생산비용을 절감시킬 수 있도록 한 새로운 형태의 탄성 투수콘크리트를 제공하는 것이다.The present invention is to solve the problems of such a conventional water-permeable package, the object is to have a resilience to increase the durability of bending toughness and freeze-thawing action, reduce the independent voids and increase the continuous voids In order to improve permeability and compressive strength, it is to provide a new type of elastic permeable concrete that can reduce environmental pollution and reduce production cost through recycling industrial wastes.
본 발명의 다른 목적은 새로운 방식의 탄성 투수콘크리트의 제조방법을 제공하는 것이다.Another object of the present invention is to provide a method for producing elastic water-permeable concrete of a new method.
본 발명의 또 다른 목적은 상기와 같이 제조된 본 발명의 탄성 투수콘크리트를 시공하는 방법을 제공하는 것이다.Still another object of the present invention is to provide a method for constructing the elastic permeable concrete of the present invention prepared as described above.

이하, 첨부된 도면에 의하여 본 발명을 보다 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
제2도는 본 발명에 따른 탄성 투수콘크리트의 부분 확대 단면도이다.2 is a partially enlarged cross-sectional view of the elastic permeable concrete according to the present invention.

본 발명에 의한 실시예를 설명하면 다음과 같다.An embodiment according to the present invention will be described below.
[실시예]EXAMPLE
본 발명에 따른 탄성 투수콘크리트의 역학적인 성질을 알아보기 위하여 실시예에서는 표 2와 같이 크기가 5.0∼8.0mm인 단입도 골재를 사용하고, 폐타이어섬유 또는 폐고무섬유의 혼입량을 각각 시멘트중량의 0%, 5%, 10%, 15% 및 20%로 하고 시멘트량을 350kg/m3으로 하여 콘크리트를 배합을 한 다음, 각종 시험용 공시체를 제작하여 본 발명에 따른 탄성 투수콘크리트의 각종 물성을 측정하였다.In order to examine the mechanical properties of the elastic permeable concrete according to the present invention in the embodiment using a single particle size aggregate of 5.0 to 8.0mm in size, as shown in Table 2, the amount of waste tire fibers or waste rubber fibers, respectively, 0%, 5%, 10%, 15% and 20% and cement content of 350kg / m 3 to mix the concrete, and then to prepare a variety of test specimens to measure the various physical properties of the elastic permeable concrete according to the present invention It was.
이와 같은 실시예에서 콘크리트의 배합에 사용한 시멘트는 비중이 3.12인 보통 포틀랜드시멘트이며, 골재는 치수가 5.0~8.0mm의 단입도 골재로서 비중이 2.64인 부순돌을 사용하였다.In this embodiment, the cement used for the mixing of the concrete is ordinary portland cement having a specific gravity of 3.12, and the aggregate used a crushed stone having a specific gravity of 2.64 as a single grain aggregate having a dimension of 5.0 to 8.0 mm.
또한, 폐타이어섬유 또는 폐고무섬유는 평균지름이 0.8mm, 길이가 2mm정도의 것을 사용하였으며, 고성능 유동화제로는 나프탈렌 술폰산 포르말린 고축합물을 주성분으로 하고, 상온에서 비중이 1,2±0.01, pH 9±1인 코리아마스터빌더즈(주)의 상품인 『Rheobuild 716』을 사용하였다.In addition, waste tire fibers or waste rubber fibers were used with an average diameter of 0.8 mm and a length of about 2 mm. The high performance fluidizing agent mainly contains naphthalene sulfonic acid formalin high-condensate, and the specific gravity is 1,2 ± 0.01 at room temperature. 『Rheobuild 716』, a product of Korea Master Builders Co., Ltd. having a pH of 9 ± 1 was used.
본 실시예에서는 상기의 조건을 갖는 각 성분들을 상기한 본 발명의 제조순서에 따라 배합하여 탄성 투수콘크리트를 제조한 다음, 그 물성에 대하여 검증을 실시하고 그 결과를 다음의 표 3에 나타내었다.In this embodiment, each component having the above conditions was blended according to the manufacturing procedure of the present invention to prepare an elastic water-permeable concrete, and then the physical properties thereof were verified and the results are shown in Table 3 below.
표 3의 투수콘크리트의 물성실험 결과를 검토해 보면, 배합에 따라 공극율이 15∼18%정도로 섬유의 혼입에 거의 상관이 없으나, 콘크리트의 투수성에 관계되는 연속공극율은 섬유의 혼입량이 증가할수록 크게 나타남을 알 수 있으며 콘크리트의 투수계수도 같은 경향을 나타내고 있다.Examining the results of the physical properties of the permeable concrete in Table 3, the porosity was about 15 to 18% depending on the blending, and it was almost irrelevant to the mixing of fibers. However, the continuous porosity related to the permeability of concrete increased as the amount of fiber was increased. The permeability coefficient of concrete shows the same trend.
따라서, 투수콘크리트속에 폐타이어섬유 또는 폐고무섬유가 고루 분포되어 시멘트풀과의 접착성이 향상되므로 연속공극율이 증가되는 것을 알 수 있다.Accordingly, it can be seen that the waste tire fibers or the waste rubber fibers are evenly distributed in the permeable concrete, thereby increasing the adhesiveness with the cement paste, thereby increasing the continuous porosity.
한편, 본 발명에 따른 탄성 투수콘크리트의 산용액에 대한 저항성과 동결융해에 대한 저항을 측정하고, 그 결과를 다음의 표 4에 나타내었다.On the other hand, the resistance to acid solution and resistance to freezing and thawing of the elastic permeable concrete according to the present invention was measured, and the results are shown in Table 4 below.
상기의 산용액에 대한 저항성을 알아보기 위하여 5% H2SO4용액에 압축강도용 공시체를 28일동안 침지시킨 후, 침지전 압축강도에 대한 침지후 압축강도의 비를 측정하였다In order to examine the resistance to the acid solution, the specimen for compressive strength was immersed in 5% H 2 SO 4 solution for 28 days, and then the ratio of the compressive strength to the compressive strength after immersion was measured.
한편, 상기의 동결융해에 대한 저항성을 알아보기 위해서는 압축강도용 탄성투수콘크리트시험체를 동결융해 시험장치 속에서 300싸이클 동안 촉진 동결융해를 실시한 다음, 동결융해실시전 압축강도에 대한 동결융해시험 실시후의 압축강도비를 측정하였다.On the other hand, in order to determine the resistance to the freeze-thawing, accelerated freeze-thawing for 300 cycles in a freeze-thawing test device for compressive strength elastic permeability concrete test, and then after freeze-thaw test on the compressive strength before freeze-thawing Compressive strength ratio was measured.
상기 표 4에서 괄호안의 수치는 시험후 압축강도에 대한 시험전 압축강도의 비를 나타내는 것이다.In Table 4, the values in parentheses indicate the ratio of the compressive strength before the test to the compressive strength after the test.
상기 표 4에서 알 수 있는 바와 같이, 본 발명에 따른 탄성 투수성 콘크리트의 압축강도는 섬유의 혼입율이 증가할수록 감소되었으나, 휨강도는 상대적으로 크게 나타남을 알 수 있다.As can be seen in Table 4, the compressive strength of the elastic permeable concrete according to the present invention was reduced with increasing the fiber mixing rate, it can be seen that the flexural strength is relatively large.
이와 같은 결과는 탄성 투수콘크리트가 포장체의 재료로 사용되는 경우에 포장체의 설계에 사용되는 휨강도 증가를 목적으로 콘크리트를 제조하는 것이 바람직하다는 것을 나타낸다.These results indicate that when elastic permeable concrete is used as the material of the package, it is desirable to manufacture concrete for the purpose of increasing the bending strength used in the design of the package.
또한, 본 발명의 탄성 투수콘크리트의 탄성계수는 섬유의 혼입율이 클수록 작게 나타나고 있는 바, 이것은 탄성 투수콘크리트 포장체의 탄성계수를 작게 하여 사람의 통행이나 자전거 등 경차의 통행에 있어서 포장체의 충격흡수능력이 향상된다는 것을 의미한다.In addition, the elastic modulus of the elastic water-permeable concrete of the present invention appears to be smaller as the fiber content ratio is larger, which is to reduce the elastic modulus of the elastic water-permeable concrete package, so that the shock absorption of the package in the passage of people or light vehicles such as bicycles It means that the ability is improved.
한편, 표 4의 내구성 실험결과에서도 알 수 있듯이 폐타이어섬유 또는 폐고무섬유의 혼입에 따라 산용액에 대한 저항성이 섬유의 혼입율이 증가할수록 우수하며, 탄성 투수콘크리트의 탄력성의 확보로 인하여 동결융해 저항성도 좋게 나타남을 알 수 있다.On the other hand, as can be seen from the durability test results of Table 4, the resistance to acid solution according to the mixing of waste tire fibers or waste rubber fibers is excellent as the fiber mixing rate increases, freeze-thawing resistance due to the elasticity of the elastic permeable concrete You can also see that it appears good.
즉, 폐타이어섬유 또는 폐고무섬유를 혼입하지 않은 보통의 투수콘크리트(배합1)의 동결융해에 대한 상대압축강도비가 36%인데 반해 상기의 폐타이어섬유 또는 폐고무섬유를 20% 혼입한 본 발명의 탄성 투수콘크리트(배합5)의 상대압축강도비는 86%로 약 2.4배 정도로 우수한 저항성이 있음을 알 수 있다.That is, the relative compressive strength ratio to freeze-thawing of ordinary permeable concrete (compound 1) that does not incorporate waste tire fibers or waste rubber fibers is 36%, whereas the above-mentioned waste tire fibers or waste rubber fibers are mixed with 20% The relative compressive strength ratio of the elastic permeable concrete (compound 5) is 86%, it can be seen that the excellent resistance of about 2.4 times.
이와 같은 본 발명에 따른 탄성투수콘크리트를 보도, 자전거도로 및 광장과 같은 경도로 등의 포장체로 사용하는 경우에, 이미 공지된 투수콘크리트의 장점인 투수기능이 확보되기 때문에 포장된 노면으로부터 노반으로 배수가 이루어지져 지하생태계를 보호할 수 있고, 우천시 자동차의 주행에 따라 발생되는 분무현상과 노면에서의 수막현상을 방지할 수 있을 뿐만아니라 도시의 지하수고갈 현상을 방지할 수 있다.When the elastic water-permeable concrete according to the present invention is used as a pavement such as a roadway, a bicycle road, and a square, such as a roadway, the water permeability from the paved road surface is drained from the paved road because the water permeation function is secured. It is possible to protect the underground ecosystem, and to prevent the spray phenomenon and water film phenomenon on the road surface in the rainy weather as well as to prevent the groundwater depletion of the city.
또한, 본 발명에 따른 탄성 투수콘크리트를 적용하는 경우에는 투수콘크리트내부에 폐타이어섬유 및 폐고무섬유가 혼입됨에 따라 탄력성이 향상되고, 단입도 쇄석골재만이 사용됨에 따라 독립공극은 감소되는 반면 연속공극은 증가되어 투수성이 향상되는 한편, 온도응력과 건조수축이 억제된다는 효과가 있으며, 포장체가 가져야 할 휨인성과 동결융해작용에 대한 내구성이 증대되므로 수명이 연장되고 사용성이 현저하게 향상된다는 장점이 있다.In addition, in the case of applying the elastic permeable concrete according to the present invention, the elasticity is improved as the waste tire fibers and the waste rubber fibers are mixed in the permeable concrete, and as the single-grained crushed aggregate is used, independent voids are reduced while being continuous. The voids are increased to improve permeability, while suppressing temperature stress and drying shrinkage, and increasing durability and flexural toughness that the package must have, thereby prolonging service life and significantly improving usability. There is this.
또한, 본 발명의 탄성 투수콘크리트를 적용하는 경우에는 독립공극의 감소에 따라 휨강도가 크게 증진되고, 압축강도 또한 종래의 투수콘크리트 보다 우수하며, 포장된 표면이 매끄럽게 된다는 효과가 있다.In addition, in the case of applying the elastic permeable concrete of the present invention, the bending strength is greatly increased according to the reduction of the independent voids, and the compressive strength is also superior to that of the conventional permeable concrete, and the packaged surface is smoothed.
