Base layer composition manufacturing step (S10), surface layer composition manufacturing step (S20) of mixing dolomite, cement with improved fineness, fluid for zero slump concrete, and water to prepare the surface layer composition, injecting the base layer composition into the mold and vibrating pressure to form the base layer A base layer molding step (S30) of forming a surface layer composition on top of the molded base layer composition and vibrating pressure to form a surface layer (S40), spraying mist on the molded base layer and the water permeable block of the surface layer structure. It includes a fog spraying step (S50), a curing step (S60) of curing the pervious block under conditions where humidity is provided, and a drying step (S70).
먼저, 상기 기층 조성물 제조단계(S10)는 굵은 골재, 잔골재, 석분, 분말도 향상 시멘트, 제로 슬럼프 콘크리트용 유동화제, 물을 혼합하여 기층 조성물을 제조한다. 상기 기층 조성물은 본 발명의 초고성능 투수블록의 기층을 형성하기 위한 조성물로, 상기 재료를 혼합하고 잘 섞이도록 교반하여 제조된다. First, in the base layer composition manufacturing step (S10), a base layer composition is prepared by mixing coarse aggregate, fine aggregate, stone dust, cement with improved fineness, a fluidizing agent for zero slump concrete, and water. The base layer composition is a composition for forming the base layer of the ultra-high performance water permeable block of the present invention, and is prepared by mixing the above materials and stirring to mix well.
본 발명의 일 실시예에 있어서, 상기 기층 조성물은 직경 10~13mm의 굵은 골재 22~28 중량%, 직경 6~8mm의 잔골재 46~50 중량%, 석분 7~9 중량%, 4,000~4,500cm2/g의 분말도를 가지는 분말도 향상 시멘트 12~15 중량%, 제로 슬럼프 콘크리트용 유동화제 0.01~3.0 중량%, 물 3~6 중량%로 구성되는 것이다.In one embodiment of the present invention, the base composition includes 22 to 28% by weight of coarse aggregate with a diameter of 10 to 13 mm, 46 to 50% by weight of fine aggregate with a diameter of 6 to 8 mm, 7 to 9% by weight of stone dust, and 4,000 to 4,500 cm 2 It is composed of 12 to 15% by weight of fineness-enhanced cement with a fineness of /g, 0.01 to 3.0% by weight of fluidizing agent for zero slump concrete, and 3 to 6% by weight of water.
상기 굵은 골재는 잔골재 대비 상대적으로 입도가 큰 것을 의미하며, 본 발명의 초고성능 투수블록의 주재료로 혼합되는 것일 수 있다. 구체적으로, 상기 굵은 골재의 입자의 직경이 10~13mm 범위의 것을 사용한다. 굵은 골재의 사용은 투수성과 강도를 동시에 고려해야 하는 것으로 굵은 골재의 직경이 10mm보다 작은 경우에는 목표 투수성에 도달하기 어려우며, 굵은 골재의 13mm를 초과하는 경우에는 강도저하가 현저하게 나타난다. The coarse aggregate means that the particle size is relatively large compared to the fine aggregate, and may be mixed as the main material of the ultra-high performance water permeable block of the present invention. Specifically, the coarse aggregate particles having a diameter in the range of 10 to 13 mm are used. When using coarse aggregate, both permeability and strength must be considered at the same time. If the diameter of the coarse aggregate is smaller than 10 mm, it is difficult to reach the target permeability, and if the diameter of the coarse aggregate exceeds 13 mm, the strength decreases significantly.
또한, 굵은 골재의 함량이 많아지면, 혼합되는 재료들 사이에 분리가 일어나 불균일한 기층이 형성되어 강도가 저하되고, 굵은 골재의 함량이 적어지면 상대적으로 공극률이 감소하여 투수성에 저하가 일어난다. In addition, as the content of coarse aggregate increases, separation occurs between the mixed materials, forming a non-uniform base layer, which reduces strength, and as the content of coarse aggregate decreases, the porosity relatively decreases, resulting in a decrease in water permeability.
상기 잔골재는 직경 6~8mm의 잔골재 46~50 중량%를 적용한다. 잔골재는 상대적으로 골재 입자의 직경이 작은 것으로 입자의 직경이 6~8mm의 것을 적용한다. 잔골재는 기층을 구성하는 주재료로서 잔골재의 함량이 많아지면 수분 함량이 높아져야 하고 그에 따라 혼합 재료 사이의 결합력에 영향을 줄 수 있고, 잔골재의 함량이 적으면 기층의 내구성 저하 및 혼합 재료의 분리가 일어난다. The fine aggregate is applied at 46 to 50% by weight of fine aggregate with a diameter of 6 to 8 mm. Fine aggregate is a relatively small aggregate particle, and particles with a particle diameter of 6 to 8 mm are used. Fine aggregate is the main material that makes up the base layer. As the content of fine aggregate increases, the moisture content must increase, which can affect the bonding strength between mixed materials. If the content of fine aggregate is small, the durability of the base layer decreases and separation of mixed materials occurs. .
석분은 골재 제조 공정 중에 발생되는 석분 슬러지를 분말화한 것으로 평균 입자크기가 6-10㎛이고, 밀도가 2.6g/cm3인 것을 사용한다. 석분은 전체 기층 조성물 중에서 7~9 중량%를 적용하는데 석분은 초고성능 투수블록의 휨강도를 증가시키고, 자연스런 색상을 표현하는데 유리하다. 석분의 사용량이 7중량% 미만으로 포함되는 경우에는 휨강도가 약해지는 문제점이 있고, 반면에 9 중량%를 초과하여 포함되는 경우에는 투수성이 저하하게 된다. Stone dust is powdered stone sludge generated during the aggregate manufacturing process, and has an average particle size of 6-10㎛ and a density of 2.6g/cm 3 . Stone dust is applied at 7 to 9% by weight of the total base composition, and stone dust is advantageous for increasing the bending strength of ultra-high performance permeable blocks and expressing natural colors. If the amount of stone dust used is less than 7% by weight, there is a problem that the bending strength is weakened, while if the amount of stone dust is included in excess of 9% by weight, water permeability is reduced.
본 발명에 따른 분말도 향상 시멘트를 전체 조성물 중 12~15 중량%로 포함된다. 통상적으로 일반 시멘트의 분말도는 KS기준으로 2800cm2/g 이상의 분말도를 가지며 포틀랜드 시멘트의 분말도는 3600~3800cm2/g의 수준이다. 본 발명에서는 이보다 훨씬 높은 4,000~4,500cm2/g의 분말도 향상 시멘트를 포함한다. 분말도가 낮으면 유동성이 증가하나 수화반응이 지연되고 재료 분리 및 압축강도 저하가 나타난다. 분말도 향상 시멘트는 높은 분말도만큼 시멘트의 표면적이 증가하게 되고 초기 강도 증가에 기여하게 되지만, 분말도가 4,500cm2/g를 초과하게 되면 수화열 상승으로 인하여 초고성능 투수블록의 강도 발현에 지장을 초래하게 된다.The fineness-enhancing cement according to the present invention is included in 12 to 15% by weight of the total composition. Typically, the fineness of general cement is more than 2800cm 2 /g based on KS, and the fineness of Portland cement is 3600 to 3800cm 2 /g. In the present invention, cement with improved fineness of 4,000 to 4,500 cm 2 /g is included, which is much higher than this. If the powder size is low, fluidity increases, but hydration reaction is delayed, material separation occurs, and compressive strength decreases. Cement with improved fineness increases the surface area of the cement as the fineness increases and contributes to the increase in initial strength. However, if the fineness exceeds 4,500 cm 2 /g, the heat of hydration increases, which hinders the development of the strength of ultra-high performance water permeable blocks. It causes.
본 발명에 따른 제로 슬럼프 콘크리트용 유동화제는 전제 조성물 중 0.1~3.0 중량%를 포함하게 된다. 제로 슬럼프 콘크리트용 유동화제는 혼합되는 수량의 감수 효과로 인해 초고성능 투수블록의 강도를 향상시키며, 기층 조성물의 균일한 혼합을 용이하게 하며, 투수 성능 향상에 기여한다. 제로 슬럼프 콘크리트용 유동화제는 폴리카르본산계, 멜라민계, 나프탈렌계 및 리그닌계 중에서 어느 하나 이상을 사용할 수 있다. The fluidizing agent for zero slump concrete according to the present invention contains 0.1 to 3.0% by weight of the total composition. The fluidizing agent for zero-slump concrete improves the strength of ultra-high-performance water permeable blocks due to the effect of reducing the amount of water mixed, facilitates uniform mixing of the base composition, and contributes to the improvement of water permeability performance. The fluidizing agent for zero slump concrete may be one or more of polycarboxylic acid-based, melamine-based, naphthalene-based, and lignin-based.
본 발명에 따른 물은 배합수로 작용하며 통상의 투수블록 제조시 사용하는 물을 모두 적용할 수 있다. 물은 3~6 중량%로 포함된다. 물을 3 중량% 미만으로 포함하게 되는 경우, 배합이 원활하게 이루어지 않아 투수블록의 불균일한 물성이 문제될 수 있으며 결합강도가 낮아질 수 있다. 물의 함량이 6 중량%를 초과하게 되면 상대적으로 다른 성분에 비해 물의 양이 많아지면서 물시멘트비(W/C)가 커짐에 따라 기층용 조성물의 슬럼프 값이 증가하게 되어 제조과정에서 재료의 분리가 일어날 수 있다. The water according to the present invention acts as mixing water, and all water used in the manufacture of conventional water permeable blocks can be applied. Water is included at 3 to 6% by weight. If water is included in less than 3% by weight, the mixing may not proceed smoothly, which may lead to problems with uneven physical properties of the permeable block and lower bonding strength. If the water content exceeds 6% by weight, the slump value of the base layer composition increases as the water cement ratio (W/C) increases as the amount of water increases relative to other components, which may cause separation of the material during the manufacturing process. You can.
도 1을 참조하면 표층 조성물 제조단계(S20)은 돌로마이트, 분말도 향상 시멘트, 제로 슬럼프 콘크리트용 유동화제, 물을 혼합하여 표층 조성물을 제조하는 것이다. 상기 표층 조성물은 본 발명의 초고성능 투수블록의 표층을 형성하기 위한조성물로 상기의 재료를 혼합하고 교반하여 제조되는 것이다. Referring to FIG. 1, the surface layer composition manufacturing step (S20) is to prepare a surface layer composition by mixing dolomite, fineness-enhanced cement, a fluidizing agent for zero slump concrete, and water. The surface layer composition is a composition for forming the surface layer of the ultra-high performance water permeable block of the present invention and is manufactured by mixing and stirring the above materials.
본 발명의 일 실시예에 있어서, 상기 표층 조성물은 돌로마이트 3호사 70~80 중량%, 4,000~4,500cm2/g의 분말도를 가지는 분말도 향상 시멘트 15~20 중량%, 물 3~7 중량% 및 제로슬럼프 콘크리트용 유동화제 0.01~3.0 중량%로 이루어진 것일 수 있다. In one embodiment of the present invention, the surface layer composition includes 70 to 80% by weight of Dolomite No. 3 sand, 15 to 20% by weight of fineness-enhanced cement with a fineness of 4,000 to 4,500 cm 2 /g, and 3 to 7% by weight of water. And it may consist of 0.01 to 3.0% by weight of a fluidizing agent for zero slump concrete.
상기 돌로마이트(dolomite)는 백운석이라고도 하며 화학성분은 CaMg(CO3)2이며 탄산칼슘(CaCO3)과 탄산마그네슘(MgCO3)이 1:1로 이루어진 복탄산염을 이룬다. 돌로마이트(dolomite) 3호사는 원석을 파쇄하여 입자 직경이 2.46~5.16mm 규격의 제품을 의미하며, 돌로마이트 4호사는 입자 직경이 1.3~2.46mm 크기의 것을 의미한다. 돌로마이트(dolomite)는 초고성능 투수블록의 표층을 형성하는 주성분으로 그 입자 직경이 초고성능 투수블록의 투수성 및 투수지속성이 큰 영향을 미친다. 따라서 투수성능 1등급(투수계수 1.0mm/sec 이상)을 달성하기 위해서는 돌로마이트 3호사를 표층 조성물 전체 중량에 대해서 70~80 중량% 포함해야 된다. The dolomite is also called dolomite, and its chemical composition is CaMg(CO 3 ) 2 and forms a complex carbonate composed of calcium carbonate (CaCO 3 ) and magnesium carbonate (MgCO 3 ) in a 1:1 ratio. Dolomite No. 3 refers to a product made by crushing raw stones and has a particle diameter of 2.46 to 5.16 mm, and Dolomite No. 4 refers to a product with a particle diameter of 1.3 to 2.46 mm. Dolomite is the main ingredient that forms the surface layer of ultra-high performance permeable blocks, and its particle diameter has a significant impact on the permeability and water permeability of ultra-high performance permeable blocks. Therefore, in order to achieve grade 1 water permeability (permeability coefficient of 1.0 mm/sec or more), 70 to 80% by weight of Dolomite No. 3 must be included based on the total weight of the surface layer composition.
4,000~4,500cm2/g의 분말도를 가지는 분말도 향상 시멘트를 표층 조성물 전체 중량에 대해서 15~20 중량%를 포함해야 한다. 분말도 향상 시멘트의 함량이 15 중량% 미만인 경우에는 혼합 재료 간의 결합강도가 저하되고 물시멘트비(W/C)가 커져서 진동 가압시 시멘트 페이스트가 표층으로 상승하여 막을 형성함으로써 투수성능이 저하되게 된다. 또한, 분말도 향상 시멘트의 함량이 20 중량%를 초과하게 되면 표층 내의 공극율이 낮아져서 투수계수가 저하될 수 있으며, 제조단가가 상승하게 된다. 15 to 20% by weight of powder-enhanced cement with a fineness of 4,000 to 4,500 cm 2 /g should be included based on the total weight of the surface layer composition. If the content of fineness-enhancing cement is less than 15% by weight, the bonding strength between the mixed materials decreases and the water-cement ratio (W/C) increases, so that the cement paste rises to the surface and forms a film during vibration pressure, thereby reducing water permeability. In addition, if the content of powder-enhancing cement exceeds 20% by weight, the porosity in the surface layer may decrease, which may lower the permeability coefficient and increase the manufacturing cost.
표층 조성물 전체 중량에 대해서 제로 슬럼프 콘크리트용 유동화제 0.01~3.0 중량%를 포함할 수 있다. 제로 슬럼프 콘크리트용 유동화제는 혼합되는 수량의 감수 효과로 인해 초고성능 투수 블록의 강도를 향상시키며, 표층 조성물의 균일한 혼합을 용이하게 하며, 투수 성능 향상에 기여한다.It may contain 0.01 to 3.0% by weight of a fluidizing agent for zero slump concrete based on the total weight of the surface layer composition. The fluidizing agent for zero slump concrete improves the strength of ultra-high performance permeable blocks due to the effect of reducing the amount of water mixed, facilitates uniform mixing of the surface layer composition, and contributes to the improvement of permeability performance.
표층 조성물 전체 중량에 대하여 물 3~7 중량%를 포함할 수 있다. 본 발명에 따른 물은 배합수로 작용하며 통상의 투수블록 제조시 사용하는 물을 모두 적용할 수 있다. It may contain 3 to 7% by weight of water based on the total weight of the surface layer composition. The water according to the present invention acts as mixing water, and all water used in the manufacture of conventional water permeable blocks can be applied.
본 발명의 또 다른 실시예에 따르면, 상기 표층 조성물은 돌로마이트 3호사 36~40 중량%, 돌로마이트 4호사 36~40 중량%, 4,000~4,500cm2/g의 분말도를 가지는 분말도 향상 시멘트 15~20 중량%, 물 3~5 중량% 및 제로슬럼프 콘크리트용 유동화제 0.01~3.0 중량%로 이루어질 수 있다. According to another embodiment of the present invention, the surface layer composition includes 36 to 40% by weight of Dolomite No. 3 sand, 36 to 40% by weight of Dolomite No. 4 sand, and 15 to 15% fineness-enhanced cement having a fineness of 4,000 to 4,500 cm 2 /g. It may consist of 20% by weight, 3 to 5% by weight of water, and 0.01 to 3.0% by weight of a fluidizing agent for zero slump concrete.
돌로마이트 3호사의 입자 직경 2.46~5.16mm 보다 작은 돌로마이트 4호사 입자 직경이 1.3~2.46mm의 재료를 혼합하여 사용함으로써 투수성능 2등급(투수계수 0.5mm/sec 이상 ~ 1.0mm/sec 미만)을 달성을 달성할 수 있다. 이 때 돌로마이트 3호사 사용량을 줄이고 그만큼 돌로마이트 4호사를 포함함으로서 투수성능을 용도에 맞게 제어할 수 있다.By using a mixture of materials with a particle diameter of 1.3 to 2.46 mm for Dolomite No. 4, which is smaller than the particle diameter of Dolomite No. 3, which is 2.46 to 5.16 mm, grade 2 water permeability (permeability coefficient 0.5 mm/sec or more to less than 1.0 mm/sec) was achieved. can be achieved. At this time, by reducing the amount of Dolomite No. 3 used and including Dolomite No. 4, the permeability performance can be controlled to suit the application.
도 1을 참고하면 기층성형단계(S30)은 상기 기층 조성물을 몰드에 주입하고 진동 가압하여 기층을 성형하는 단계이다. 상기 몰드(Mold)는 초고성능 투수블록을 성형하기 위한 것을 의미하는 것으로 정육면체, 직육면제, 그 외의 입체적 구조를 가진 형태도 가능하며 투수블록의 형태와 품질기준에 따라 몰드를 설계하여 사용하는 것일 수 있다. Referring to FIG. 1, the base layer forming step (S30) is a step of forming the base layer by injecting the base layer composition into a mold and applying vibration pressure. The mold is meant to form an ultra-high-performance water permeable block. It can be in the form of a cube, rectangular plane, or other three-dimensional structure. The mold can be designed and used according to the shape and quality standards of the water permeable block. there is.
상기 몰드에 기층용 조성물을 넣고 진동을 가하게 되면, 기층용 조성물이 몰드 내에서 고르게 분산되면서 일정한 두께를 갖는 기층으로 성형된다. 이 후 가압 장치를 이용하여 성형된 기층을 상부에서 가압함으로써 기층의 성형이 완성된다. When the base layer composition is placed in the mold and vibration is applied, the base layer composition is evenly dispersed within the mold and is formed into a base layer with a constant thickness. Afterwards, the forming of the base layer is completed by pressurizing the molded base layer from the top using a pressurizing device.
진동 가압은 통상의 장비를 사용하여 수행하는 것으로 진동장치는 예를 들어 서로 반대방향으로 회전하는 편심축을 가진 한쌍의 드럼의 회전에 의해서 발생하는 진동력을 이용하는 것이다. 이 때 진동장치는 35~45rpm의 속도로 회전하면서 진동을 인가하고, 진동 인가 시간은 1.2~1.5초이다. 진동 시간이 1.2초 미만인 경우에는 기층 조성물의 분산이 미흡하게 되어 물성 불균일이 발생하고 진동시간이 1.5초를 초과하게 되면 기층내 공극이 감소하게 되어 투수성이 감소하게 된다. Vibration pressurization is performed using conventional equipment, and the vibration device uses, for example, the vibration force generated by the rotation of a pair of drums with eccentric axes rotating in opposite directions. At this time, the vibration device applies vibration while rotating at a speed of 35 to 45 rpm, and the vibration application time is 1.2 to 1.5 seconds. If the vibration time is less than 1.2 seconds, the dispersion of the base layer composition becomes insufficient, resulting in non-uniform physical properties, and if the vibration time exceeds 1.5 seconds, the pores within the base layer are reduced, thereby reducing water permeability.
도 1을 참고하면 표층 성형단계(S40)은 상기 표층 조성물을 성형된 기층 상부에 고르게 투입하고 진동 가압하여 표층을 형성하는 단계이다. 몰드 내에 성형된 기층 위에 상기 표층 조성물을 넣고 진동을 가하여 기층의 상면에 표층 조성물이 분산되면서 표층을 형성하는 것일 수 있다. 이후 진동, 가압을 통해 기층의 상면에 적층된 표층을 기층과 결합하고 표층의 성형을 완성한다. Referring to Figure 1, the surface layer forming step (S40) is a step of forming a surface layer by evenly adding the surface layer composition to the upper part of the molded base layer and vibrating pressure. The surface layer composition may be placed on the base layer molded in a mold and vibrated to form a surface layer as the surface layer composition is dispersed on the upper surface of the base layer. Afterwards, the surface layer laminated on the upper surface of the base layer is combined with the base layer through vibration and pressure, and the forming of the surface layer is completed.
진동 가압은 기층의 성형에 사용한 진동 및 가압 장치를 이용하는 것이다. 이 때 진동장치는 35~45rpm의 속도로 회전하면서 진동을 인가하고, 진동 인가 시간은 1.3~1.6초 이다. 진동 인가 시간이 1.3초 미만인 경우에는 표층 조성물의 분산이 미흡하게 되어 물성 불균일이 발생하게 되고, 진동 인가시간이 1.6초를 초과하게 되면 시멘트 페이스트가 표층의 상부로 밀려 올라와 시멘트 막을 형성함으로써 투수 성능을 급격하게 저하시키는 문제가 발생하게 된다. Vibration pressurization uses the vibration and pressurization device used to form the base layer. At this time, the vibration device applies vibration while rotating at a speed of 35 to 45 rpm, and the vibration application time is 1.3 to 1.6 seconds. If the vibration application time is less than 1.3 seconds, the dispersion of the surface layer composition becomes insufficient, resulting in uneven physical properties. If the vibration application time exceeds 1.6 seconds, the cement paste is pushed up to the top of the surface layer to form a cement film, reducing water permeability. A problem of rapid deterioration occurs.
상기 표층은 정해진 표준 규격에 따른 두께를 갖도록 형성된 것을 수 있으며, 표층의 두께는 6~8mm 이내로 제작되어야 한다. The surface layer may be formed to have a thickness according to established standard specifications, and the thickness of the surface layer should be manufactured within 6 to 8 mm.
도 1을 참고하면 안개분사단계(S50)는 기층과 표층 구조의 투수블록에 미스트를 분사하는 단계이다. 통상의 미스트 발생장치에서 직경 30㎛ 내지 70㎛ 이하의 미스트를 생성시켜 기층과 표층 구조의 투수블록 상부에 3~5 초간 분사한다. 초고성능 투수블록은 표층을 형성할 때 표층 상부로 시멘트가 밀려 올라와 막을 형성함으로써 투수성능이 저하되는 것을 방지하기 위해서 표층의 물시멘트비(W/C)를 최소로 함으로써 표면의 수화반응이 충분하지 못해 표면강도가 저하하게 된다. 이에 미스트를 분사하여 표층 상부에서부터 내부로 미스트가 침투하면서 충분한 수화반응이 가능하도록 수분을 공급하여 강도를 향상시키고 투수성을 유지할 수 있는 처리 단계이다. Referring to Figure 1, the mist spraying step (S50) is a step of spraying mist on permeable blocks of the base layer and surface layer structure. A typical mist generator generates mist with a diameter of 30㎛ to 70㎛ or less and sprays it on the upper part of the water permeable block of the base layer and surface layer structure for 3 to 5 seconds. When forming the surface layer, ultra-high performance water permeable blocks minimize the water-cement ratio (W/C) of the surface layer to prevent the water permeability performance from deteriorating due to cement being pushed up to the top of the surface layer and forming a film, thereby preventing sufficient surface hydration reaction. Surface strength decreases. Accordingly, this is a treatment step in which mist is sprayed and penetrates from the top of the surface layer to the inside, supplying moisture to enable a sufficient hydration reaction, thereby improving strength and maintaining water permeability.
미스트의 크기가 직경 70㎛ 보다 크게 되면 표층의 표면 침투가 용이하지 않으며, 30㎛ 미만이면 너무 쉽게 표층 내부로 침투되어 표면 수화반응 효과가 감소하게 된다. If the size of the mist is larger than 70㎛ in diameter, it is difficult to penetrate the surface layer, and if it is less than 30㎛, it penetrates too easily into the surface layer, reducing the effect of the surface hydration reaction.
도 1을 참고하면 양생단계(S60)는 상기 기층과 표층으로 이루어진 초고성능 투수블록을 온습도를 제어하면서 양생하여 경화시켜 투수블록을 형성하는 것이다. 본 발명에 따른 양생단계는 1차 양생단계(S61)로 온도 35~38℃, 습도 80~90%의 조건에서 24시간 양생한다. 이와 같은 양생 조건에 의하여 기층과 표층의 강도 발현 속도를 향상시킬 수 있으며 양생시간을 단축할 수 있다. 38℃의 온도를 초과하는 경우 투수블록 표면입자의 수화물이 치밀해서 내부의 수화 진행이 방해되면서 최종 강도가 저하될 수 있다. Referring to Figure 1, the curing step (S60) is to cure and harden the ultra-high performance permeable block composed of the base layer and the surface layer while controlling the temperature and humidity to form a permeable block. The curing step according to the present invention is the first curing step (S61), which is cured for 24 hours at a temperature of 35 to 38 ° C and humidity of 80 to 90%. Through these curing conditions, the speed of strength development of the base and surface layers can be improved and the curing time can be shortened. If the temperature exceeds 38°C, the hydrate on the surface particles of the permeable block is dense, which may hinder the internal hydration process and reduce the final strength.
또한, 본 발명에 따른 양생단계는 2차 양생단계(S62)로 25℃ 이상의 온도에서 100℃ 증기를 이용하여 48시간 2차 양생을 수행한다. 2차 양생은 추가 수분을 공급하여 수화반응을 촉진시켜 강도 증진의 효과가 있다. In addition, the curing step according to the present invention is the secondary curing step (S62), in which secondary curing is performed for 48 hours using 100°C steam at a temperature of 25°C or higher. Secondary curing has the effect of improving strength by supplying additional moisture and promoting the hydration reaction.
최종적으로 별도의 건조시설에서 15~25℃ 온도에서 3~5일간 자연 건조를 수행하여 초고성능 투수블록의 제조가 완성된다. Finally, the production of ultra-high performance water permeable blocks is completed by natural drying for 3 to 5 days at a temperature of 15 to 25 degrees Celsius in a separate drying facility.
