본 발명은 본 발명은 타설된 콘크리트(C)의 표면층과 양생필름(10) 사이에 생성된 물막이 양생필름(10)에 의해 장기간 보전되므로 콘크리트(C)의 내,외층에서 균일한 양생이 이루어져 표면층에 수축건조에 의한 균열이 발생하는 것을 방지할 수 있으며, 또한, 콘크리트(C)에 의한 각종 구조물을 견실하게 시공할 수 있는 등의 효과가 있다.According to the present invention, since the water film generated between the surface layer of the poured concrete (C) and the curing film 10 is preserved for a long time by the curing film 10, the surface layer is uniformly cured in the inner and outer layers of the concrete (C). It is possible to prevent the occurrence of cracks caused by shrinkage drying, and also to stably construct various structures made of concrete (C).
Description
본 발명은 콘크리트의 양생공법 및 양생필름에 관한 것으로서, 좀더 상세히는 타설된 콘크리트의 초기 건조시에 발생될 수 있는 균열을 예방하면서 콘크리트의 내외층에서 균일한 양생이 이루질 수 있도록 한 콘크리트의 양생공법과 그와 같은 양생공법을 구현하기 위한 양생필름에 관한 것이다.The present invention relates to a curing method and a curing film of concrete, more specifically curing the concrete to achieve uniform curing in the inner and outer layers of concrete while preventing cracks that may occur during the initial drying of the poured concrete It relates to a curing film and a curing film for implementing such a curing method.
콘크리트의 양생에 있어서 균열(표면 균열)을 일으키는 가장 큰 원인중의 하나가 건조수축에 의한 균열인데, 위와 같은 건조수축은 타설된 콘크리트의 양생과정에서 외부와 접하는 표면에 대한 건조가 먼저 이루어져 수축작용을 일으키고 내부는 수분을 함유하고 있는 상태를 유지하기 때문에 수분을 함유하고 있는 내부층이 표면의 수축작용을 구속하게 됨으로써 타설된 콘크리트의 표면에 인장력이 발생함에 기인한다.One of the biggest causes of cracking (surface cracking) in the curing of concrete is cracking caused by dry shrinkage. The above dry shrinkage is performed by drying the surface that is in contact with the outside during curing of the cast concrete. The inner layer retains moisture, and the inner layer containing moisture constrains the contraction of the surface, thereby causing tensile forces on the surface of the poured concrete.
즉, 내외층의 불균형 양생에 의해 콘크리트의 표면에 발생한 인장응력이 콘크리트의 인장강도를 초과하게 되면 타설된 콘크리트의 표면에 건조수축이 발생하게 되는 것이다.That is, when the tensile stress generated on the surface of the concrete by the imbalance curing of the inner and outer layers exceeds the tensile strength of the concrete, dry shrinkage occurs on the surface of the poured concrete.
상기한 건조수축을 방지하기 위해서는 타설된 콘크리트의 양생시에 표면층에 항상 적당량의 물기(물막)를 유지시켜 콘크리트의 내외층에서 균일한 양생이 이루어지도록 해야 하는데, 콘크리트의 표면층에 공급된 물기는 햇빛에 의해 쉽게 증발되어 버리기 때문에 짧은 간격으로 대량의 물을 공급해주어야 한다는 번거로움이 따를 수밖에 없다.In order to prevent the above-mentioned drying shrinkage, it is necessary to maintain an appropriate amount of water (water film) on the surface layer at all times during curing of the poured concrete so that uniform curing can be achieved in the inner and outer layers of the concrete. Because it is easily evaporated by, it is inevitable to supply a large amount of water at short intervals.
실질적으로 일반의 공사현장에서는 콘크리트의 양생시에 타설된 콘크리트의 초기 건조가 있은 후에 콘크리트위에 부직포를 덮은 다음 부직포상에 물을 뿌려주며 양생을 진행하는 습윤양생을 주로 이용하고 있으나, 위와 같은 습윤양생은 콘크리트의 초기 건조가 있은 후에 이루어지는 것이기 때문에 타설된 콘크리트의 초기 건조과정에서 발생되는 초기 균열을 방지할 수 없었을 뿐만 아니라 부직포상에 공급된 물이 쉽게 증발되어 습윤양생의 효과를 기대하기 어려웠으며, 또한, 부직포는 그 부피가 크고 무겁기 때문에 사용 및 운반이 불편하다는 등의 문제점이 지적되고 있다.그리고, 타설된 콘크리트가 굳기 전에 표면에 피막재를 살포하거나 비닐을 덮어씌우는 봉합양생이 있는데, 위 봉합양생은 콘크리트가 함유하고 있는 자체의 수분증발을 억제시킬 수 있도록 한 것으로서 이또한 외부로부터의 수분의 공급이 없기 때문에 콘크리트의 초기 건조과정에서 발생되는 균열을 방지하기가 어려웠을 뿐만 아니라 콘크리트의 초기 건조가 있은 후에 습윤양생을 위해서는 비닐을 제거하는 번거로움이 따르게 된다.In practice, general construction sites mainly use wet curing, which covers the non-woven fabric on concrete and sprinkles water on the non-woven fabric after the initial drying of the concrete poured during the curing of concrete. Since this is done after the initial drying of the concrete, it was not possible to prevent the initial crack occurring during the initial drying process of the poured concrete, and it was difficult to expect the effect of wet curing because the water supplied to the nonwoven fabric was easily evaporated. In addition, problems such as the nonwoven fabric is bulky and heavy, which makes it difficult to use and transport, and there is a suture cure that spreads the coating material or covers the vinyl before the cast concrete hardens. Curing suppresses the evaporation of moisture in concrete In addition, since there is no supply of water from the outside, it is difficult to prevent cracks generated during the initial drying process of concrete, and it is troublesome to remove vinyl for wet curing after the initial drying of concrete. This will follow.
상기와 같은 각각의 사유로 인해 콘크리트의 양생공정(습윤양생, 봉합양생)에는 양생에 필요한 적당량의 물을 공급하기 위해서 방대한 살수장비와 인력이 투입될 수밖에 없었으며, 위와 같은 요인은 시공비용의 상승을 주도하는 주요인의 하나로 지적되고 있다.위와 같은 양생의 절차(물막의 생성)를 무시한 상태로 공사를 진행할 경우 콘크리트의 강도저하 및 균열발생에 의한 부실공사로 이어져 자칫 대형사고가 유발될 수 있다는 중차대한 문제점이 발생하게 된다.Due to each of the above reasons, in the curing process of the concrete (wet curing, suture curing) was forced to supply a large amount of watering equipment and manpower in order to supply the appropriate amount of water required for curing, such as the increase in construction cost It is pointed out as one of the main factors leading to the construction.If the construction process is ignored while the curing procedure (creation of water film) is neglected, it can lead to poor construction due to the decrease in strength of the concrete and the occurrence of cracks. Problems will arise.
본 발명은 전술한 바와 같은 종래 콘크리트 양생공정에서 발생되었던 제반 문제점을 일소하기 창출된 것으로서, 모세관 및 표면장력의 원리를 이용하여 물기의 공급은 원활히 이루어지면서 공급된 물기에 의해 생성된 물막의 증발이 억제되도록 함으로써 타설된 콘크리트의 표면에 장시간 동안 보전되는 물막을 생성시켜 콘크리트의 내외층에서 균일한 양생이 이루어지도록 함에 기술적 과제의 주안점을 두고 완성한 콘크리트의 양생공법과 그 공법을 구현하기 위한 양생필름을 제공한다.The present invention was created to eliminate all the problems caused in the conventional concrete curing process as described above, by using the principle of capillary and surface tension, the supply of water is made smoothly while the evaporation of the water film generated by the supplied water is The cured film and the cured film for realizing the construction method of concrete completed with the focus of the technical problem to create a water film that is preserved for a long time on the surface of the poured concrete by making it suppressed to achieve uniform curing in the inner and outer layers of the concrete. to provide.

본 발명은 타설된 콘크리트(C)의 표면에 얇은 합성수지 등으로 제작되는 양생필름(10)을 부착시켜 콘크리트(C)와 양생필름(10) 사이에 1~3mm의 중공영역(S)이 형성되도록 하는 단계와, 양생필름(10)에 "-"형으로 절개되는 다수개의 유입구(20)를 형성하는 단계와, 상기 부착된 양생필름(10)상에 물을 살수하는 단계를 포함한다.The present invention is attached to the curing film 10 made of a thin synthetic resin, etc. on the surface of the poured concrete (C) to form a hollow area (S) of 1 ~ 3mm between the concrete (C) and the curing film (10) And forming a plurality of inlets 20 which are cut in the curing film 10 in a "-" shape, and spraying water on the attached curing film 10.
상기 과정에 있어서 양생필름(10)에 형성되는 유입구(20)는 그 길이(L1)가 20mm를 초과하지 않도록 하고 유입구(20)의 폭은 폭(L2)이 0.2mm를 넘지 않도록 하며, 각각의 유입구(10)의 형성간격(L)은 50mm를 초과하지 않도록 함이 바람직하다.In the inlet 20 formed in the curing film 10 in the above process so that the length (L1) does not exceed 20mm and the width of the inlet 20 so that the width (L2) does not exceed 0.2mm, each Forming interval (L) of the inlet 10 is preferably not to exceed 50mm.
본 발명은 양생필름(10)상으로 공급된 물(W)이 양생필름(10)에 형성된 유입구(20)를 통해 양생필름(10)과 콘크리트(C) 사이에 형성된 중공영역(S)으로 유입되고 유입된 물기가 양생필름(10)과 콘크리트(C)사이에 물막을 생성하게 되는 것인데, 유입된 물기가 유입구(20)를 통해 유입되는 것은 모세관 현상에 기인하며 유입된 물기에 의한 물막의 형성은 유입된 물기의 표면장력에 기인한다.즉, 모세관의 원리에 의해 미세한 폭을 갖는 유입구(20)를 통해 양생필름(10)과 콘크리트(C) 사이의 중공영역(S)으로 유입된 물기는 양생필름(10)과 콘크리트(C) 사이에서 표면장력을 발생시키게 되고, 위 표면장력에 의해 양생필름(10)의 유입구(20) 주변에 잔재하는 물기가 흡수되여 중공영역(S) 내에 물막이 형성되는 것이다.In the present invention, the water (W) supplied onto the curing film 10 is introduced into the hollow region S formed between the curing film 10 and the concrete C through the inlet 20 formed in the curing film 10. And water is introduced into the water film between the curing film 10 and the concrete (C). The inflow of water through the inlet 20 is caused by a capillary phenomenon. Is due to the surface tension of the introduced water. That is, the water introduced into the hollow region S between the curing film 10 and the concrete C through the inlet 20 having a fine width by the principle of capillary The surface tension is generated between the curing film 10 and the concrete C, and water remaining in the periphery of the inlet 20 of the curing film 10 is absorbed by the surface tension to form a water film in the hollow region S. Will be.
한편, 본 발명에 있어서 양생필름(10)의 이면에 수분에 대한 함습율이 우수한 직물(40)을 부착한 상태에서 양생필름(10)을 콘크리트(C)에 부착할 수 있는데, 이와 같은 경우에는 양생필름(10)을 벽체 등과 같이 수직으로 타설된 콘크리트(C)에 부착하여 수분을 공급하게 되면 공급된 구분이 유입구(20)를 통해 유입되어 직물(40)에 함습되므로 벽체를 따라 바닥면으로 흘러내리지 않게 된다.On the other hand, in the present invention, the curing film 10 can be attached to the concrete (C) in a state in which the fabric 40 excellent in moisture content against the moisture on the back surface of the curing film 10 is attached, When the curing film 10 is attached to vertically cast concrete (C) such as a wall to supply moisture, the supplied separator is introduced through the inlet 20 to be moistened in the fabric 40, and thus the floor surface is along the wall. It will not flow down.
양생필름(10)과 콘크리트(C)에 형성된 중공영역(S)내로 유입된 물기는 표면장력이 발생하여 양생필름(10)을 당기는 형태로 물막을 생성하게 되며 위 생성된 물막은 양생필름(10)에 의해 증발이 억제되는데, 중공영역(S)내에 생성된 물막의유지는 8시간 이상동안 이루어졌으며 하절기에 이루어진 자체적인 시험결과는 하기의 도표와 같이 나타났다.The water flowing into the hollow area S formed in the curing film 10 and the concrete C generates surface tension to generate a water film in the form of pulling the curing film 10, and the water film generated above is the curing film 10. Evaporation is suppressed, and the water film generated in the hollow area S was maintained for more than 8 hours, and its own test results in the summer are shown in the chart below.
도 2에 본 발명에서 제시하는 양생필름(10)이 도시되는데, 양생필름(10) 얇은 합성수지로 제작되는 비닐(vinyl) 등과 같은 형태를 이루며 양생필름(10)의 표면에는 그 형성간격(L)이 50mm를 초과하지 않는 다수개 유입구(20)를 형성한다.The curing film 10 shown in the present invention is shown in FIG. 2, wherein the curing film 10 forms a shape such as vinyl, which is made of a thin synthetic resin, and has a forming gap L on the surface of the curing film 10. A plurality of inlets 20 are formed that do not exceed 50 mm.
상기 유입구(20)는 그 길이(L1)가 20mm를 넘지 않고 폭(L2)이 0.2mm를 넘지 않는 "-"형 절개홈의 형태를 이루도록 함이 바람직한데, 그 이유는 유입구(20)의 길이(L1)와 폭(L2)을 지나치게 크게 형성할 경우에는 외부 영향(바람 등)으로 유입구(20)가 쉽게 벌려지게 되어 양생필름(10)내로 유입되는 물기가 쉽게 증발될 우려가 있기 때문이다.The inlet 20 is preferably such that the length (L1) does not exceed 20mm and the width (L2) to form the shape of the "-" incision groove does not exceed 0.2mm, because the length of the inlet 20 If the L1 and the width L2 are too large, the inlet opening 20 is easily opened due to external influences (wind, etc.), and the water flowing into the curing film 10 may be easily evaporated.
상기 양생필름(10)의 저면에는 양면테이프 등과 같은 수개의 부착수단(30)을 장착하여 부착수단(30)을 이용하여 양생필름(10)을 콘크리트(C)의 표면에 부착시킬 수 있도록 한다.(도 3 참조.)The bottom surface of the curing film 10 is equipped with several attachment means 30 such as a double-sided tape to attach the curing film 10 to the surface of the concrete (C) by using the attachment means (30). (See Figure 3.)
한편, 본 발명에서는 양생필름(10)을 부착시키기 위한 부착수단(30)으로 양면테이프 등과 같은 접착수단을 이용하는 구성에 대해 설시하고 있으나, 상기 부착수단(30)은 양생필름(10)을 콘크리트(C)에 부착시켜 줄 수 있는 여타의 다른 구성으로 치환될 수 있다. 즉, 부착수단(30)은 단지 양생필름(10)을 콘크리트(C)에 부착시켜 주기 위한 수단에 지나지 않는 것이어서 부착수단(30)을 치환하는 행위가 본 발명이 향유하고자 하는 기술적 사상에 별반의 영향을 끼칠 수는 없다 할 것이다.On the other hand, the present invention has been described for the configuration using an adhesive means such as double-sided tape as the attachment means 30 for attaching the curing film 10, the attachment means 30 is the curing film 10 to concrete ( It may be substituted with other configuration that can be attached to C). That is, the attachment means 30 is only a means for attaching the curing film 10 to the concrete (C), so that the act of replacing the attachment means 30 is contrary to the technical idea that the present invention intends to enjoy. It will not affect.
이상의 구성을 갖는 양생필름(10)은 그 이면에 부착된 부착수단(30)을 보호하고 있는 보호지(31)를 떼어낸 상태에서 타설된 콘크리트(C)의 표면에 부착하여 사용하는 것인데, 콘크리트(C)의 표면에 덮여진 양생필름(10)위에 물(W)을 뿌려 주면 공급된 물(W)이 모세관 현상에 의해 양생필름(10)에 형성된 유입구(20)를 통해 양생필름(10)과 콘크리트(C) 사이의 중공영역(S)으로 유입된다.Curing film 10 having the above configuration is used to attach to the surface of the cast concrete (C) in the state of removing the protective paper 31 protecting the attachment means (30) attached to the back surface, the concrete ( C) If water (W) is sprayed on the cured film 10 covered on the surface of the supplied water (W) through the inlet 20 formed in the cured film 10 by the capillary phenomenon and the curing film 10 and It is introduced into the hollow region S between the concrete (C).
상기 유입된 물에는 표면장력이 발생하여 양생필름(10)의 유입구(20) 주변에 잔재하는 물을 흡수하게 되고 흡수된 물은 콘크리트(C)의 표면층과 양생필름(10) 사이의 중공영역(S)에서 1~3mm 두께의 물막을 생성시키게 되는데, 양생필름(10)의 유입구(20)는 그 폭(L2)이 매우 미세하므로 모세관 원리에 의해 외부의 물기가 쉽게 유입되는 것이며 콘크리트(C)의 표면층과 양생필름(10) 사이에 생성된 물막은 대부분의 영역을 밀폐하고 있는 양생필름(10)에 의해 그 증발이 억제되므로 중공영역(S)내로 유입된 물기가 장기간 동안 보전되는 것이다.Surface tension is generated in the introduced water to absorb the residual water around the inlet 20 of the curing film 10, and the absorbed water is a hollow region between the surface layer of the concrete C and the curing film 10. S) to produce a water film of 1 ~ 3mm thickness, the inlet 20 of the curing film 10 is because the width (L2) is very fine, the external water is easily introduced by the capillary principle and concrete (C) The water film generated between the surface layer of the cured film 10 and the evaporation is suppressed by the cured film 10 that seals most of the region is to maintain the water flowing into the hollow area (S) for a long time.
도 4에 본 발명에서 제시하는 양생필름(10)의 다른 실시예를 도시한 단면도가 도시되는데, 도시된 바와 같이 상기 양생필름(10)의 이면에 직물(40)을 부착하고, 상기 부착된 직물(40)의 이면에 부착수단(30)을 부착한다.4 is a cross-sectional view showing another embodiment of the curing film 10 presented in the present invention, and attaches the fabric 40 to the back surface of the curing film 10 as shown, and the attached fabric Attaching means 30 is attached to the back of the 40.
도 5에 본 발명에서 제시하는 양생필름(10)의 또다른 실시예를 도시한 단면도가 도시되는데, 도시된 바와 같이 양생필름(10)의 표면에 직물(40)을 부착하고, 상기 양생필름(10)의 이면에 또 다른 직물(40)을 부착한 다음 양생필름(10)의 이면에 부착된 직물(40)에 부착수단(30)을 부착한다.5 is a cross-sectional view showing another embodiment of the curing film 10 presented in the present invention, as shown in the fabric 40 attached to the surface of the curing film 10, the curing film ( Attach another fabric 40 to the back side of 10) and then attach the attachment means 30 to the fabric 40 attached to the back side of the curing film 10.
양생필름(10)에 직물(40)을 부가하여 부착시킬 경우 벽체 등과 같이 수직으로 타설되는 콘크리트(C)에 부착하여 사용할 수 있는데, 양생필름(10)의 표면에 뿌려진 물이 유입구(20)를 통해 유입된 다음 양생필름(10)과 콘크리트(C) 사이의 중공영역(S)에 위치하게 되는 직물(40)에 함습되어 밑으로 흘러내리지 않게 되며 직물(40)에 함습된 수분은 콘크리트(C)의 표면에 물막을 생성시켜준 것과 같은 효과를 발생시켜 주는 것이다.한편, 본 발명에서는 양생필름(10)의 표면에 형성되는 유입구(20)가 "-"형 절개홈의 형태를 이루도록 하였는데, 위와 같은 유입구(20)의 실시는 일예에 국한되는 것이고 본 발명이 향유하는 기술적 사상에 의해서는 유입구(20)를 원형의 통공 형태로 형성할 수 있음은 물론이다.위와 같이 양생필름(10)의 표면에 절개홈을 대체하는 통공 형태로 유입구(20)를 형성할 경우 형성되는 유입구(20)의 직경은 1mm이상 3mm이하가 되도록 하여야 하고 유입구(20)의 형성간격은 20mm이내가 되도록 하는 조건을 충족하여야 한다.상기와 같이 유입구(20)의 형성조건을 충족시켜야 이유는 유입구(20)의 직경이 1mm이하가 되면 양생필름(10)내로 물이 잘 유입되지 않게 되고 유입구(20)의 직경이 3mm이상이 될 경우 유입된 물의 증발이 쉽게 일어나기 때문이며, 또한, 유입구(20)의 형성간격이 지나치게 넓을 경우 양생필름(10)과 콘크리트의 표면 사이로 유입된 물이 양생되는 콘크리트의 표면 전체에 고르게 퍼지기까지 소요되는 시간이 다소 지연되어 작업성이 떨지지게 되고 유입구(20)의 형성간격이 너무 좁은 경우에는 유입된 물에 대한 증발억제의 효과가 떨어지기 때문이다.When the fabric 40 is attached to the curing film 10, the fabric 40 may be attached to the concrete C, which is placed vertically, such as a wall. The water sprayed on the surface of the curing film 10 may be used to attach the inlet 20. Moisture is impregnated in the fabric 40 to be placed in the hollow area (S) between the curing film 10 and the concrete (C) is not flowed down to flow through the water and the moisture is impregnated in the fabric (40) In the present invention, the inlet 20 formed on the surface of the curing film 10 to form a "-" type incision groove, The implementation of the inlet 20 as described above is limited to one example, and according to the technical spirit of the present invention, the inlet 20 may be formed in a circular through shape. In the form of a hole to replace the incision in the surface When the inlet 20 is formed, the diameter of the inlet 20 formed should be 1 mm or more and 3 mm or less, and the formation interval of the inlet 20 should satisfy the condition of 20 mm or less. When the diameter of the inlet 20 is less than 1mm, water does not flow well into the curing film 10. When the diameter of the inlet 20 becomes 3mm or more, the evaporation of the inflowed water This is because it easily occurs, and if the formation interval of the inlet 20 is too wide, the time required for evenly spreading the entire surface of the cured concrete with the water introduced between the curing film 10 and the surface of the concrete is slightly delayed. This is because the fall off and the formation interval of the inlet 20 is too narrow because the effect of the evaporation suppression on the introduced water is reduced.
본 발명은 양생필름(10) 상에 뿌려진 물이 미세한 폭을 갖는 유입구(20)를 통해 양생필름(10)과 콘크리트(C) 사이에 형성되는 중공영역(S)으로 유입되도록 한 것인데, 유입구(20)의 폭이 미세하므로 모세관 현상에 의해 물기의 유입은 쉽게 이루어지게 되며, 유입된 물기가 갖는 표면장력으로 인해 양생필름(10)의 유입구(20) 주변에 잔재하는 물기가 점차적으로 흡수되어 양생필름(10)과 콘크리트(C) 사이의 중공영역(S)에 물막이 생성되고, 위와 같이 생성된 물막은 대부분의 영역을 밀폐시키고 있는 양생필름(10)에 의해 그 증발이 억제되므로 양생필름(10) 상에 물을 한번만 공급해주어도 콘크리트(C)의 표면에 상당시간 동안 물막이 형성되어 타설된 콘크리트(C)에 대해서는 수조 양생의 효과가 발생하는 것이다.According to the present invention, the water sprayed on the curing film 10 is introduced into the hollow region S formed between the curing film 10 and the concrete C through an inlet 20 having a fine width. 20) the width of the microscopically facilitates the inflow of water by the capillary phenomenon, due to the surface tension of the water flows in the water remaining around the inlet 20 of the curing film 10 is gradually absorbed by curing A water film is generated in the hollow region S between the film 10 and the concrete C, and the water film generated as described above is cured by evaporation by the curing film 10 which seals most of the region. Even if the water is supplied only once, water film is formed on the surface of the concrete (C) for a considerable time, and the effect of curing the tank is generated for the poured concrete (C).
본 발명은 콘크리트의 타설 직후에 콘크리트의 표면에 덮어 씌운 상태에서 살수를 하며 양생공정을 진행시킬 수 있도록 한 것으로서 타설된 콘크리트(C)의 초기 건조시에도 물을 살수할 수 있어 초기 건조시에 발생할 수 있는 초기 균열을 미연에 방지할 수 있을 뿐만 아니라 콘크리트의 타설 직후에 설치한 양생필름(10)을 공정이 완료될 때가지 사용(파손을 배제할 경우)할 수 있으므로 상당한 경제적인 잇점을 득할 수 있다.The present invention is to allow water to be sprinkled in the state of covering the surface of the concrete immediately after the concrete is poured, so that water can be sprinkled even during the initial drying of the poured concrete (C). Not only can early cracks be prevented in advance, but the cured film 10 installed immediately after the concrete can be used until the process is completed (when the damage is excluded), thereby obtaining significant economic advantages. have.
본 발명은 타설된 콘크리트(C)의 표면층에 생성된 물막을 장기간 동안 보전시켜 콘크리트(C)의 내,외층에서 균일한 양생이 이루어지며 표면층의 수축건조에 의한 균열을 방지할 수 있는 것이다.The present invention is to maintain the water film generated in the surface layer of the cast concrete (C) for a long time to achieve uniform curing in the inner and outer layers of the concrete (C) and to prevent cracking by shrinkage drying of the surface layer.
본 발명은 콘크리트(C)의 표면층과 양생필름(10) 사이에 생성된 물막이 8시간 이상 보전되기 때문에 물의 낭비를 방지할 수 있음은 물론 살수에 따른 인력 및 장비의 소모를 최소화 할 수 있어 공사비용을 현격하게 절감시킬 수 있는 등 그 기대되는 효과가 실로 다대한 매우 유익한 발명인 것이다.The present invention can prevent the waste of water because the water film generated between the surface layer and the curing film 10 of the concrete (C) for more than 8 hours, as well as to minimize the consumption of manpower and equipment due to watering construction cost It is possible to significantly reduce the expected effect is indeed a very beneficial invention.
