More specifically, it is manufactured in the form of dry mortar, so that waterproofing work is possible by just mixing water, which not only facilitates workability, but also has excellent adhesion strength and compressive strength. It is excellent, so there is no need to perform additional protective mortar work on the surface of the waterproofing layer. It absorbs weight impact well, reduces noise between floors, prevents cracks, improves self-leveling properties, reduces construction labor costs, and has excellent elasticity. It relates to a powder-type elastic coated waterproofing composition containing regenerated fibers that provides a waterproof layer that exhibits excellent durability against vibration or external shock.
일반적으로 액체형 시멘트 방수재는 물이 90 내지 92 중량%, 지방산나트륨 성분이 8 내지 10 중량%가 혼합된 형태의 방수재로 형체형 시멘트 방수재의 제조는 1종 보통 시멘트 2 중량%, 모래 0 내지 0.5 중량% 및 물 2 내지 4 중량%를 혼합하여 이루어지며, 제조된 방수 시멘트 페이스트를 구조물의 표면에 4mm 이상의 두께로 바름작업을 시행한다.In general, liquid cement waterproofing material is a mixture of 90 to 92% by weight of water and 8 to 10% by weight of sodium fatty acid. The production of liquid cement waterproofing material is usually 2% by weight of cement and 0 to 0.5% by weight of sand. % and 2 to 4% by weight of water, and the prepared waterproof cement paste is applied to the surface of the structure to a thickness of 4 mm or more.
또한, 액체형 시멘트 방수재의 방수보호몰탈의 제조는 액체형의 방수재 1 중량%에 대해 1종 시멘트 2 중량%, 모래 4 내지 6 중량%, 물 2 내지 4 중량%를 혼합하여 이루어지며, 구조물의 표면에 4mm 이상의 두께로 바름작업을 시행한다.In addition, the production of waterproof protective mortar for liquid cement waterproofing is done by mixing 2% by weight of type 1 cement, 4 to 6% by weight of sand, and 2 to 4% by weight of water with respect to 1% by weight of liquid waterproofing material, and applied to the surface of the structure. Apply with a thickness of 4mm or more.
액체형 시멘트 방수재의 시공순서는 구조물의 바닥의 경우에는 1층(바탕면 정리 및 물청소), 2층(방수 시멘트 페이스트 1차), 3층(방수액 침투), 4층(방수 시멘트 페이스트 2차) 및 5층(방수 보호몰탈)의 순서로 진행되며, 구조물의 벽체 및 천장용 시공 순서는 1층(바탕면 정리 및 물청소), 2층(바탕접착제 도포), 3층(방수 시멘트 페이스트), 4층(방수 보호몰탈)의 순서로 진행된다. The construction order of liquid cement waterproofing material is as follows: 1st floor (base preparation and water cleaning), 2nd layer (1st waterproofing cement paste), 3rd layer (penetration of waterproofing liquid), 4th floor (2nd waterproofing cement paste) in the case of the floor of the structure. It is carried out in the order of the 5th floor (waterproofing protection mortar), and the construction order for the walls and ceiling of the structure is 1st floor (base preparation and water cleaning), 2nd floor (application of base adhesive), 3rd floor (waterproofing cement paste), It is carried out in the order of the 4th layer (waterproof protection mortar).
이와 같이 액체형 시멘트 방수재의 시공 방법은 방수 시멘트 페이스트를 바르고 양생되는 시간을 기다렸다가 방수 시멘트 페이스트를 바르거나 방수 보호몰탈을 바르는 방법으로 방수작업이 진행되어야 하기 때문에, 공정이 번거롭고 이로 인한 인건비의 상승이 문제점으로 지적되고 있다.In this way, the construction method of liquid cement waterproofing material requires waterproofing work to be carried out by applying waterproof cement paste, waiting for the curing time, and then applying waterproof cement paste or waterproof protective mortar, so the process is cumbersome and the resulting increase in labor costs is a problem. It is pointed out that
또한, 현장에서 액체형 방수재에 시멘트와 모래 그리고 물을 넣고 방수 시멘트 페이스트 및 방수 보호몰탈을 제조해야 되므로, 현장에서 정확한 배합비에 맞춰 배합을 진행하기고 어렵고, 배합된 방수 시멘트 페이스트 및 방수 보호몰탈이 배합비에 맞게 배합되었는지를 확인이 어렵기 때문에 균일한 품질과 성능의 방수공사가 이루어지지 않는 문제점이 있었다.In addition, since cement, sand and water must be added to the liquid waterproofing material to produce waterproof cement paste and waterproof protective mortar on site, it is difficult to mix the mixture according to the exact mixing ratio on site, and the mixed waterproof cement paste and waterproof protective mortar must be mixed at the mixing ratio. There was a problem in that waterproofing work of uniform quality and performance was not carried out because it was difficult to check whether the mixture was properly mixed.
또한, 액체형 방수재는 물을 기반으로 제조하는 방수재로서, 겨울철에 유통 및 보관 중에 액체형 방수재가 동결되면 방수성능이 급격하게 저하되므로, 동결된 액체형 방수재는 폐기처분해야 하는 문제점이 있었다.In addition, the liquid waterproofing material is a waterproofing material manufactured based on water. If the liquid waterproofing material freezes during distribution and storage in winter, the waterproofing performance deteriorates rapidly, so there is a problem in that the frozen liquid waterproofing material must be disposed of.

It is a water-curing inorganic adhesive and is the most commonly used material in the production of concrete or mortar, and is inexpensive and easy to purchase. It has the advantage of being easy to use, so it is preferable to use one type of ordinary Portland cement, and it is more preferable to use one with a fineness of 3,200 cm 2 /g.
상기 레미탈(Remitar)은 80 내지 120 중량부가 함유되며, 초속경 시멘트 100 중량부에 건조모래 80 내지 230 중량부를 혼합하여 이루어지는데, 본 발명에 따른 분말형 탄성 도포방수재에 조기강도 발현 효과를 부여할 뿐만 아니라, 부착 강도, 모재와의 친화성, 동결융해 저항성 및 내화학적 안정성이 향상된 방수층이 제공될 수 있도록 하는 역할을 한다.The Remitar contains 80 to 120 parts by weight and is made by mixing 80 to 230 parts by weight of dry sand with 100 parts by weight of ultra-fast hardening cement, which gives an early strength development effect to the powdered elastic coating waterproofing material according to the present invention. In addition, it serves to provide a waterproof layer with improved adhesion strength, affinity with the base material, freeze-thaw resistance, and chemical stability.
이때, 상기 초속경 시멘트는 레미탈에 사용될 수 있는 성분이면 특별히 한정되지 않고 어떠한 것이든 사용가능하나, 규산삼석회, 규산이석회, 알루민산삼석회, 철(鐵)화합물 및, 석고를 비롯하여, 초속경 특성을 부여하는 무수석고 100 중량부에 알루미나 또는 칼슘설포알루미네이트를 100 내지 200 중량부 혼합하여 이루어지는 것을 사용하는 것이 바람직하다.At this time, the rapid hardening cement is not particularly limited as long as it is a component that can be used in Remital, and any material can be used, including trilime silicate, dicalcium silicate, tricalcium aluminate, iron compounds, and gypsum, It is preferable to use a product made by mixing 100 to 200 parts by weight of alumina or calcium sulfoaluminate with 100 parts by weight of anhydrous gypsum, which provides rapid hardening properties.
상기 초속경 시멘트는 수화 반응에 의해 다량의 에트린자이트(ettringite) 광물을 생성하는데, 에트린자이트는 침상결정체로서 부피가 상당히 크기 때문에 수화 초기에 약간의 팽창성을 나타내며, 이로 인해 일반 포틀랜드 시멘트에서의 문제점인 침하현상이나 건조 수축이 거의 없는 우수한 특성을 나타낼 뿐만 아니라, 2 내지 3 시간의 단기간에 실용강도를 발현하도록 하며, 격렬한 반응으로 인해 수화열이 많이 발생하고, 단열상태의 콘크리트에서는 내부 온도가 50℃ 이상으로 상승하기도 하여, 저온에서도 자체 발열에 의해 반응을 촉진시키고, 정상적인 반응이 진행되도록 하는 효과를 나타낸다.The rapid hardening cement produces a large amount of ettringite mineral through a hydration reaction. Ettringite is a needle-shaped crystal and has a fairly large volume, so it exhibits a slight expansion at the beginning of hydration, which causes it to be different from general Portland cement. Not only does it exhibit excellent properties with almost no sinking or drying shrinkage, which are problems of It may rise above 50℃, which has the effect of promoting the reaction through self-heating even at low temperatures and allowing normal reactions to proceed.

It fills the voids between the ordinary Portland cement particles, thereby improving water tightness and improving adhesion and compressive strength. , it is preferable to use one with a fineness of 6500 to 7000 cm 2 /g and an average particle size of 3 to 5 ㎛.
상기 마이크로 시멘트의 함량이 8 중량부 미만이면 상기 포틀랜드 시멘트 입자사이의 공극이 발생되어 수밀성이 저하되고, 부착강도와 압축강도가 저하되며, 상기 마이크로 시멘트의 함량이 12 중량부를 초과하게 되면 경제성이 저하된다.If the content of the micro cement is less than 8 parts by weight, voids are generated between the Portland cement particles, which reduces watertightness and reduces adhesion strength and compressive strength. If the content of the micro cement exceeds 12 parts by weight, economic feasibility decreases. do.
상기 재생섬유는 0.8 내지 1.2 중량부가 함유되며, 길이가 3 내지 8 밀리미터를 나타내는데, 폐기처분되어 환경의 오염을 야기할 수 있는 합성섬유의 폐기물을 재생한 재생섬유를 사용하여 친환경적인 효과를 나타내면서도 양생된 방수층에 탄성을 부여하고, 외부의 충격이나 진동으로 인해 방수층이 구조물로부터 탈락하거나 방수층에 균열이 발생하는 것을 방지하여 방수층의 내구성을 향상시키는 역할을 한다.The recycled fiber contains 0.8 to 1.2 parts by weight and has a length of 3 to 8 millimeters. It is eco-friendly by using recycled fiber obtained from synthetic fiber waste that can be disposed of and cause environmental pollution. It provides elasticity to the cured waterproofing layer and improves the durability of the waterproofing layer by preventing the waterproofing layer from falling off the structure or cracking due to external shock or vibration.

상기 습식방수제제조단계(S105)를 통해 제조된 습식방수제를 구조물의 바닥에 도포하는 두께가 12 밀리미터 미만이면 방수층의 방수성능이 저하되며, 습식방수제를 구조물의 바닥에 도포하는 두께가 18 밀리미터를 초과하게 되면 방수층의 방수효과는 크게 향상되지 않으면서 경제성이 저하된다.If the thickness of the wet waterproofing agent produced through the wet waterproofing agent manufacturing step (S105) is applied to the bottom of the structure is less than 12 millimeters, the waterproofing performance of the waterproof layer deteriorates, and the thickness of the wet waterproofing agent applied to the bottom of the structure exceeds 18 millimeters. If this is done, the waterproofing effect of the waterproofing layer will not be significantly improved and economic efficiency will decrease.
또한, 상기 습식방수제제조단계(S105)를 통해 제조된 습식방수제를 구조물 벽면에 도포하는 두께가 6 밀리미터 미만이면 방수층의 방수효과가 미미하며, 습식방수제를 구조물의 벽면에 도포하는 두께가 10 밀리미터를 초과하게 되면 양생전에 흘러내림 현상으로 인해 균일한 두께의 방수층을 형성할 수 없게 된다.In addition, if the thickness of the wet waterproofing agent manufactured through the wet waterproofing agent manufacturing step (S105) is applied to the wall of the structure is less than 6 millimeters, the waterproofing effect of the waterproof layer is minimal, and the thickness of the wet waterproofing agent applied to the wall of the structure is 10 millimeters. If it exceeds it, it will not be possible to form a waterproof layer of uniform thickness due to the phenomenon of flowing down before curing.
상기 양생단계(S107)는 상기 방수제도포단계(S105)를 통해 구조물의 표면에 도포된 방수제를 양생하는 단계로, 상기 양생단계(S107)의 조건은 특별히 한정되지 않고, 상기 방수제도포단계를 통해 구조물의 표면에 도포된 방수제를 상온에서 양생시켜 방수층을 형성하는 과정으로 이루어진다.The curing step (S107) is a step of curing the waterproofing agent applied to the surface of the structure through the waterproofing agent application step (S105). The conditions of the curing step (S107) are not particularly limited, and the structure is cured through the waterproofing agent application step (S105). It consists of curing the waterproofing agent applied to the surface at room temperature to form a waterproofing layer.
