종래기술Prior art
종래의 불투수성 콘크리트로 포장시의 문제점들 즉 강우시 포장체의 표면으로 물이 고이거나 흐름으로써 통행에 지장을 주거나 지하수 고갈, 폭우시 하천으로의 물의 유입으로 인한 범람 등의 문제점들을 해결하기 위하여 투수성을 지니는 콘크리트에 대한 기술이 다수 개발되어 있으며, 세립형 투수콘크리트에 대해서도 기 층에 19㎜이하 및 13~25㎜의 골재를 사용한 후 표층용으로 1~3㎜, 3~5㎜의 세립골재를 사용하는 기술 등이 개발되어 있다.Pitcher to solve the problems of pavement with conventional impermeable concrete, namely, water impingement on the surface of pavement in case of rainfall, impede passage, depletion of groundwater, flooding due to inflow of water into river during heavy rain Many technologies for concrete have been developed, and fine granular aggregates of 1 ~ 3mm and 3 ~ 5mm are used for surface layer after using aggregates of less than 19mm and 13 ~ 25mm for base permeable concrete. Techniques for using this have been developed.
그러나 상기와 같은 기존 세립형 투수콘크리트의 경우 기층용 투수콘크리트의 골재 입도가 표층용 세립골재의 입도에 비해 월등히 크기 때문에 기층용 투수콘크리트의 공극에 세립골재가 끼는 문제가 있고, 상대적으로 위로 돌출된 기층용 투수콘크리트에 세립골재가 채워지므로 세립 투수콘크리트를 정확하고 일정한 두께로 포설하고 외관을 미려하게 하는 작업을 하는데 어려움이 많았다. 또한 종래에는 세립골재의 경우 극히 작은 크기의 골재를 사용하거나 다양한 크기의 골재를 혼합하여 사용하지 않아 작은 충격에도 표층이 쉽게 파손되거나 박리 현상이 발생하여 내구성을 보장하기 어려운 문제점이 있었다. 또한 세립골재의 입자 크기를 극히 좁은 범위로 한정하는 것은 크기가 한정된 골재의 생산량이 적어 경제적인 부담도 있었다.However, in the case of the existing fine-grain permeable concrete as described above, since the aggregate particle size of the ground-permeable concrete is significantly larger than that of the surface fine-grained aggregate, the fine aggregate is trapped in the pores of the permeable concrete for the base, and protrudes relatively upward. Since fine granules are filled in the base permeable concrete, it was difficult to install the fine grain permeable concrete in a precise and constant thickness and to make the appearance beautiful. In addition, conventional fine grain aggregates do not use very small aggregates or mix aggregates of various sizes so that the surface layer is easily broken or a peeling phenomenon occurs even at a small impact, making it difficult to guarantee durability. In addition, limiting the grain size of the fine aggregates to an extremely narrow range was also an economic burden due to the small amount of aggregates with limited size.
한편 제강슬래그는 선철, 고철과 같은 제강원료를 정련하는 과정에서 전기로 또는 전로로부터 발생되는 산업폐기물로서, 이를 활용하지 않고 그대로 폐기시키는 경우 비산먼지, 침출수와 같은 환경문제가 발생하였다. 이에 이를 활용하기 위한 다양한 연구가 있어왔다. On the other hand, steel slag is an industrial waste generated from an electric furnace or converter in the process of refining steel raw materials such as pig iron and scrap metal. If it is disposed of as it is without using it, environmental problems such as scattering dust and leachate have occurred. Thus, there have been various studies to utilize this.

이하에서는 본 발명의 바람직한 실시예를 기술함으로써, 본 발명을 상세히 설명한다. Hereinafter, the present invention will be described in detail by describing preferred embodiments of the present invention.
1. 투수콘크리트 조성물1. Permeable Concrete Composition
(1)기층용 투수콘크리트 조성물(1) permeable concrete compositions for substrates
본 발명의 기층용 투수콘크리트는 1㎥당 13㎜이하의 골재를 85~100중량% 함유한 골재 1,500~1800㎏, 물 90~130㎏, 시멘트 260~370㎏, 상기 시멘트의 0.7~2.5중량%의 고성능 AE감수제로 구성된다. 이때 고성능 AE감수제는 시공되는 계절 및 용도에 따라 선택하여 사용한다. 투수콘크리트에서 감수제의 첨가는 시멘트의 경화에 필요한 수분을 감소시켜 콘크리트 구축물이 한겨울에 함수(含水)로 인해 동결 파손되는 문제를 해결하여 준다. 고성능 AE감수제를 0.7중량% 미만 사용하는 경우 감소되는 물의 양이 너무 적어 강도가 약해지는 문제가 있고, 2.5중량%를 초과하는 경우 콘크리트의 경화가 적절히 이루어지지 않는 문제가 있다.The base permeable concrete of the present invention aggregates 1,500 ~ 1800kg, water 90 ~ 130kg, cement 260 ~ 370kg, containing 85 ~ 100% by weight of aggregate less than 13mm per 1m 3, 0.7 ~ 2.5% by weight of the cement It consists of a high performance AE water reducer. At this time, the high performance AE reducing agent is used according to the season and the purpose of construction. The addition of a water reducing agent in the permeable concrete reduces the moisture required for the hardening of the cement and solves the problem of freezing and breakage of concrete structures due to moisture in the winter. When using a high-performance AE water reducing agent less than 0.7% by weight, the amount of water to be reduced is too small, there is a problem that the strength is weakened, when it exceeds 2.5% by weight there is a problem that the curing of the concrete is not properly made.
(2)세립 투수콘크리트 조성물(2) fine grain permeable concrete composition
본 발명의 세립 투수콘크리트는 1㎥당 4.75㎜체 통과율이 85%내외이고 1.2㎜ 체 통과율이 15%내외인 세립골재 1,530~2,050㎏, 물 74~120㎏, 시멘트 270~400㎏, 상기 시멘트의 0.7~2.5중량%의 고성능 AE감수제로 구성된다.The fine-grain permeable concrete of the present invention is a fine aggregate aggregate 1,530 ~ 2,050kg, water 74 ~ 120kg, cement 270 ~ 400kg, the cement of the 4.75mm sieve passage rate of about 85% and 1.2mm sieve passage rate of about 15% per m3 It is composed of 0.7 ~ 2.5% by weight of high performance AE water reducing agent.
이때, 상기 세립골재는 1개월 이상 물에 침지 또는 물을 분사하여 에이징시킨 5mm이하의 제강슬래그 골재를 전체 세립골재의 15~35중량%로 포함하는 것이 바람직하다. At this time, the fine aggregate is preferably 1 to more than 1 month immersed in water or sprayed with water, the steel slag aggregate of 5mm or less is preferably 15 to 35% by weight of the total fine aggregate.
제강슬래그는 내부에 유리산화칼슘을 함유하고 있어 물과 접촉시 화학반응을 일으켜 부피가 팽창되어 시멘트의 결합력을 붕괴시켜 균열발생의 원인이 될 수 있으므로 상기와 같이 에이징시켜 화학적으로 안정화시킨 후 사용하는 것이다. 상기와 같은 산업폐기물인 제강슬래그의 사용은 폐자원을 그대로 폐기하지 않고 활용하여 환경을 보호하게 한다. 제강슬래그는 15중량% 이상 사용하여야 제강슬래그를 재활용하고자 하는 목적에 부합하며, 35중량%를 초과하여 사용하는 경우에는 강도 저하의 우려가 있다. Since steel slag contains free calcium oxide inside, chemical reaction occurs upon contact with water, and the volume expands, which can cause the bond strength of cement to collapse, which can cause cracking. will be. The use of steel waste slag as an industrial waste as described above allows to protect the environment by utilizing the waste resources as they are. Steelmaking slag should be used more than 15% by weight to meet the purpose of recycling steelmaking slag, when using more than 35% by weight there is a fear of strength degradation.
(3)상기와 같이 기층용 투수콘크리트 조성물의 골재를 13㎜이하의 골재 85~100중량%로 구성하고, 상기 기층용 투수콘크리트의 포설 후 그 위에 사용되는 세립 투수콘크리트의 세립골재를 1㎥당 4.75㎜체 통과율이 85%내외이고 1.2㎜체 통과율이 15%내외인 세립골재로 구성함으로써, 기존에 기층용 투수콘크리트의 골재가 표층용 세립골재에 비해 상대적으로 월등히 커 기층용 콘크리트의 공극에 세립형 골재가 끼어 세립형 투수콘크리트를 정확하고 일정한 두께로 포설하는 것이 어려웠던 문제점 및 작은 충격에도 쉽게 파손되던 문제점 등을 해결하였다. 즉 기층용 골 재와 세립골재의 크기를 상기와 같이 구성하여 용이하게 표면을 평탄하게 하고, 표면강도를 강화시켰다. 또한, 본 발명은 상기와 같은 구성의 골재에서도 높은 투수성을 제공한다. (3) As described above, the aggregate of the base-permeable concrete composition is composed of aggregates of 85 to 100% by weight of 13 mm or less, and the fine-grained aggregate of fine-grain permeable concrete to be used thereon after laying the base-permeable concrete per 1 m 3. By constructing fine-grained aggregates with a 4.75mm sieve passing rate of around 85% and a 1.2mm sieve passing rate of around 15%, the aggregate of permeable concrete for basement is significantly larger than that of surface granular aggregates. It solved the problem that it was difficult to install fine-grain permeable concrete with accurate and constant thickness due to mold aggregate and easily broken even with small impact. That is, the size of the base aggregate and the fine aggregate is configured as described above to easily flatten the surface and enhance the surface strength. In addition, the present invention provides a high permeability even in the aggregate of the above configuration.
2. 투수콘크리트의 시공방법2. Construction method of permeable concrete
본 발명의 투수콘크리트의 시공은 (a)상기 기층용 투수콘크리트를 포설하는 제1공정; (b)상기 기층용 투수콘크리트의 표면이 건조되기 전에 상기 세립 투수콘크리트 조성물을 포설하는 제2공정; 및, (c)상기 포설된 세립 투수콘크리트 조성물의 상부를 로울러로 다지고 양생시키는 제3공정;으로 이루어질 수 있다.The construction of the water-permeable concrete of the present invention comprises: (a) a first step of laying the base-permeable concrete; (b) a second step of laying the fine-grain permeable concrete composition before the surface of the base-permeable concrete is dried; And, (c) a third step of compacting and curing the top of the laid fine grain-permeable concrete composition with a roller.
이때 (d)균열방지를 위한 줄눈을 위한 컷팅작업과 줄눈에 백업제를 투입한 후 폴리머를 도포하는 제4공정을 더 포함할 수 있다.At this time, (d) may further include a fourth step of applying a polymer after the cutting operation for the joint to prevent cracking and putting the backup agent in the joint.
제1공정은 상기 기층용 투수콘크리트를 포설하는 과정으로 기층용 투수콘크리트는 35~65㎜의 두께로 포설한다. 그리고, 상기 기층용 투수콘크리트의 표면이 건조되기 전에 상기의 세립 투수콘크리트를 포설하는 제2공정을 진행한다. 이때 기층용 투수콘크리트의 1차 포설 후 2시간 이내에 세립 투수콘크리트를 포설하는 것이 바람직하다. 세립 투수콘크리트의 포설은 15~35㎜의 두께로 하는 것이 바람직하다. 세립 투수콘크리트의 경우 주로 보행자 및 자전거 전용도로의 포장에 사용되는 경우가 다수로 대개 7㎝내외로 시공하는데, 상기 기층용 투수콘크리트 및 표층용 세립 투수콘크리트의 두께는 용도에 따라 변경할 수 있다. 그리고, 상기 포설된 세 립 투수콘크리트는 2.5~3.5톤의 로울러 등으로 다지고 양생하는 제3공정을 거치게 된다.The first step is to install the permeable concrete for the base, and the permeable concrete for the base is laid in a thickness of 35 to 65 mm. Then, before the surface of the base permeable concrete is dried, a second step of laying the fine grain permeable concrete is performed. At this time, it is preferable to install the fine-grain permeable concrete within 2 hours after the first installation of the permeable concrete for base layer. The fine grain permeable concrete is preferably laid in a thickness of 15 to 35 mm. In the case of fine grain permeable concrete, mainly used for paving pedestrian and bicycle roads, the construction is usually about 7 cm, and the thickness of the ground permeable concrete and surface fine grain permeable concrete may be changed depending on the use. In addition, the laid fine pitched concrete is subjected to a third process of compacting and curing with a roller of 2.5 to 3.5 tons.
제4공정은 균열방지 및 표면의 외관을 미려하게 하기 위한 공정으로 줄눈을 위한 컷팅을 행하고, 줄눈에 압축스티로폴 및 실리콘과 같은 백업제를 투입한 후 폴리머를 도포한다. 폴리머로는 에폭시, 아크릴, 우레탄 등을 사용할 수 있다. The fourth step is a process for preventing cracks and beautiful appearance of the surface, cutting for joints, applying a backing agent such as compressed styropol and silicon to the joints, and then applying a polymer. Epoxy, acryl, urethane, etc. can be used as a polymer.
