Description
본 발명은 세라믹고화혼화제 및 부직포를 이용한 방수공법에 관한 것으로 더욱 구체적으로는 침투용세라믹고화혼화제(#4000)를 물로 수화시킨 침투용세라믹고화혼화액을 콘크리트 구조체에 1단계로 하도(프라이마코팅)한 다음 그 위에 토목섬유사로된 부직포를 깔고 다시 그 위에 상기 침투용세라믹고화혼화액을 도포한 후, 코팅하여 로울러로 다짐으로써 부직포 내로 충분히 침투시킨 다음, 부직포고화층 위에 도포용세라믹고화혼화액 또는 몰탈을 타설 용도별로 5∼15mm 두께로 도포하여 정형 고화시키는 세라믹고화혼화제 및 부직포를 이용한 방수공법에 관한 것이다.The present invention relates to a waterproofing method using a ceramic solidified admixture and a nonwoven fabric. More specifically, the ceramic ceramic mixed admixture (# 4000), which has been hydrated with water, is applied to a concrete structure in one step (prima coating). Then, lay a nonwoven fabric made of geosynthetic yarn on it, and apply the ceramic solidification admixture on it again, and then penetrate into the nonwoven by coating and compacting with a roller, and then apply the ceramic solidification admixture on the nonwoven fabric solidification layer. Or it relates to a waterproofing method using a ceramic solidifying admixture and a non-woven fabric by applying mortar to a thickness of 5 to 15mm by pouring.
현재 국내에서 건축물의 옥상이나 지하외벽, 지하주차장, 상부슬라브방수와 지하철, 지하차도, 각종 구조물의 공동구조물에 적용되는 방수방법은 크게 아스팔트방수(열공법), 시트방수, 우레탄도막방수, 침투성도포방수, 벤토나이트방수, 고무화수지 아스팔트이중방수 등으로 구분된다.Currently, the waterproofing methods applied to rooftops, underground exterior walls, underground parking lots, upper slab waterproofing, and joint structures of subways, underground roads, and various structures in Korea are mainly waterproofing asphalt (heating method), sheet waterproofing, waterproofing urethane coating, and permeable coating. It is divided into waterproof, bentonite waterproof and rubberized resin asphalt double waterproof.
이상의 방수공법의 하자발생요인 80∼90%가 들뜸현상, 연결접합불량, 방수층의 박리현상 등이다. 이러한 하자발생요인을 가지는 기존의 방수공법에 사용되는 재료를 살펴보면, 일정한 자구방수기능으로 하는 무기계방수재료와, 유기접착방수제를 응용한 방수재료와, 고무시트, 아스팔트, 벤토나이트 등에 수지계 화합물을 수용성 상태에서 혼합 접목시킨 방수재료 등이 있다. 그러나 상기 재료는 방수층과 콘크리트 구조체간의 다른 물성으로 인하여 콘크리트 구조체와 방수고화층이 지속적으로 굳어지면서 각각 다른 물성간의 결합력으로 인하여 접착된 부분이 탈리되어, 들뜸현상이 발생된다. 이러한 들뜸현상으로 인하여 방수처리 후 2~3년만 경과하여도 방수층에 누수가 발생되어 수밀성을 확보할 수 없다는 문제점이 있었다.The above 80 ~ 90% of the defects of the waterproofing method are the phenomenon of lifting, poor connection and peeling of the waterproof layer. Looking at the materials used in the existing waterproofing method having such a defect generation factor, the inorganic waterproofing material having a certain self-waterproof function, the waterproofing material applied with the organic adhesive waterproofing agent, and the resin-based compound in the rubber sheet, asphalt, bentonite, etc. Mixed materials and waterproof materials. However, the material is continuously stiffened due to the different physical properties between the waterproof layer and the concrete structure, and the bonded portions are detached due to the bonding force between the different physical properties, causing the phenomenon of lifting. Due to this lifting phenomenon, even after two or three years after the waterproofing treatment, there was a problem in that water leakage occurred in the waterproofing layer to ensure watertightness.
달리 표현하면 기존 시멘트계방수재료, 무기계침투성방수재료, 수지계방수재료 및 중합계 접착방수재료 등은 기존 방수구조체인 콘크리트 구조체와 상이한 분자구조에 따른 상이한 전하성질로 인하여 접착 자체의 분자응집력을 완벽하게 기대할 수 없는 바, 이로 인하여 방수 구조체와 방수층 간에 들뜸, 탈리현상이 발생되는 문제점이 있었다.In other words, existing cement-based waterproofing materials, inorganic impermeable waterproofing materials, resin-based waterproofing materials, and polymeric adhesive waterproofing materials are expected to fully expect the molecular cohesion of the adhesive itself due to the different charge properties according to the molecular structure different from the existing waterproof structures. Due to this, there was a problem that the lifting, detachment phenomenon occurs between the waterproof structure and the waterproof layer.
본 발명은 상기와 같은 종래 방수기술방법의 문제점을 해결하기 위하여, 무기계 고화재료의 개념과 무기계, 수지접착제료를 공중합물로 극성을 개량한 개념으로서, 두개성질의 재료가 하나의 성질로 고화접착되는 세라믹혼화제를 토목섬유인 부직포를 거푸집으로 하여 방수 구조체에 고착접합, 코팅시킨 후, 그 위에 몰타르를 이용하여 마감하는 세라믹고화혼화제 및 부직포를 이용한 방수공법을 제공함에 있다.또한, 본 발명은 강알카리성분에 의한 부직포의 열화현상을 방지하고 부직포에 쉽게 침투될 수 있도록 하기 위해, 저알카리성분으로서 물에 의해 수화된 세라믹고화혼화액을 사용함으로써 연속접합 시공성이 우수하고 복잡한 구조체에서도 용이하게 작업성을 확보할 수 있는 세라믹고화혼화제 및 부직포를 이용한 방수공법을 제공함에도 목적이 있다.The present invention, in order to solve the problems of the conventional waterproofing method as described above, the concept of the inorganic solidification material and the concept of improving the polarity of the inorganic and resin adhesives as a copolymer, the two materials of the material solidified adhesiveness with one property The present invention provides a waterproofing method using a ceramic solidifying admixture and a nonwoven fabric, which are bonded to and coated on a waterproof structure using a nonwoven fabric made of geotextile as a formwork, and then finished using mortar thereon. In order to prevent deterioration of the nonwoven fabric by alkali components and to easily penetrate into the nonwoven fabric, it is excellent in continuous bonding construction by using a ceramic solidified liquid hydrated by water as a low alkali component and easily workable even in a complicated structure. In addition to providing a waterproofing method using a ceramic solidified admixture and a nonwoven fabric that can ensure Never.

여기에서 평면으로 몰탈층을 시공하는 경우는 함수율이 높은 범위로 채택하고 경사면에서는 몰탈의 흘러내림을 방지하기 위하여 낮은 함수율을 채택한다.이상과 같은 본 방법에 의한 부직포고화방수층과 부직포고화몰탈방수층의 물성을 알아보기 위하여 실시예로 나타내었다.실시예(1)① 침투용세라믹고화혼화제(#4000)를 수화시킨 침투용세라믹고화혼화액으로 하도층을 1mm두께가 되게 하도하고, 그 위에 3mm의 부직포를 첨착시킨 후, 다시 침투용세라믹고화혼화액을 3mm두께로 충분히 침투시킨 다음, 다시 그 위에 도포용세라믹고화혼화액으로 3mm두께가 되도록 형성하여 약 8mm두께의 부직포고화방수층(A)을 얻었다.② 실시예(1)의 ①에서와 같이 침투용세라믹고화혼화액으로 하도 및 부직포(3mm)에 침투공정까지는 동일하게 처리하고 그 위에 10mm두께가 되도록 몰탈(중량비로 세라믹고화혼화제(#4200) 30중량부와 세사 또는 충진제 70중량부, 함수율 30wt%)로 방수마감층을 형성 전체 두께 약 15mm의 부직포고화몰탈방수층(A')을 얻었다.③ 침투용세라믹고화혼화액으로 하도층을 1mm두께로 하도하고, 그 위에 5mm두께의 부직포를 첨착시킨 다음, 상기 세라믹고화혼화액(#4000)으로 4mm두께로 충분히 침투시킨 다음, 그 위에 도포용세라믹고화혼화액으로 3mm두께로 방수마감층을 형성시키므로써 전체 두께 약 9mm의 부직포고화방수층(B)을 얻었다.이때 3mm두께 방수마감층에는 도포용세라믹고화혼화제(#4200) 50중량비에 세사 30중량비에 충진제 20중량비로 하여 그 혼합비로 하였다.④ 실시예(1)의 ③에서와 같이 침투용세라믹고화혼화액의 부직포 침투공정 후 부직포고화층 위에 10mm두께가 되도록 몰탈(중량비로 도포용세라믹고화혼화제(#4200) 30중량부와 모래 50중량부 및 충진제 20중량부, 함수율 30wt/%)로 방수마감층을 형성시키므로 전체 두께 약 16mm의 부직포고화몰탈방수층(B')을 얻었다.상기 실시예(1)에서 시공한 방법으로 얻어진 방수층의 물성을 알아보면 표4와 같다.표4) 부직포고화방수증 및 부직포고화몰탈방수층 물성 비교표 In this case, when the mortar layer is planarly applied, the moisture content is selected in a high range, and on the inclined surface, a low moisture content is adopted in order to prevent the mortar from flowing down. In order to find out the physical properties, it is shown as an Example. Example (1) ① The infiltration ceramic solidification admixture (# 4000) was hydrated to make the undercoat layer 1 mm thick. After impregnating the nonwoven fabric, the penetrating ceramic solidified solution was sufficiently penetrated to a thickness of 3 mm, and again formed thereon to be 3 mm thick with the ceramic ceramic mixed solution for coating to obtain a nonwoven fabric waterproofing layer (A) having a thickness of about 8 mm. ② In the same manner as in ① of Example (1), the same process is applied to the bottom coating and the nonwoven fabric (3mm) until the penetration process is performed. A water-resistant finish layer was formed of 30 parts by weight of a mortar (# 4200), 70 parts by weight of fine yarn or filler, and 30 wt% of water content) to obtain a nonwoven fabric mortar waterproofing layer (A ') having a total thickness of about 15 mm. The undercoating layer is 1mm thick with a ceramic solidification mixture for penetration, and a nonwoven fabric having a thickness of 5mm is deposited thereon, and the ceramic solidification mixture (# 4000) is sufficiently infiltrated with 4mm thickness, and then the ceramic for application is applied thereon. By forming a waterproofing finish layer with a thickness of 3mm with a solidified admixture, a nonwoven fabric waterproofing waterproofing layer (B) having a total thickness of about 9mm was obtained. The mixing ratio was set to 20 weight ratio of the filler. ④ Mortar (coating ratio by weight ratio) was made to have a thickness of 10mm on the nonwoven fabric solidification layer after the nonwoven fabric infiltration process of the ceramic solidification mixture for infiltration as in ③ of Example (1). 30 parts by weight of mixed admixture (# 4200), 50 parts by weight of sand, 20 parts by weight of filler, and 30 wt /% water content were formed to form a waterproofing finish layer, thereby obtaining a nonwoven fabric-dehydrated mortar dewatering layer (B ') having a total thickness of about 16 mm. The properties of the waterproof layer obtained by the method constructed in Example (1) are shown in Table 4.

본 발명에 의한 방수공법은 알루미나광물, 석회석 및 석고를 소성하여 소성반응으로 얻어진 알루미나생석회 및 석고의 착염으로 구성된 크링커를 미세분말화하여 이에 물을 첨가하는 경우 수경화 반응에 의하여 1∼10㎛ 침상결정인 에트린자이트(Ettringite)가 생성된다. 특히 석고의 첨가는 수화반응촉진으로 다량의 간극수를 소비하여 응결시간이 단축되고 수화반응이 촉진되는 바, 이로 인하여 더 많은 에트린자이트가 생성되어 방수성이 뛰어난 경화체를 형성할 수 있는 효과가 있다.The waterproofing method according to the present invention finely powders a clinker composed of alumina lime and a complex salt of gypsum obtained by calcining alumina mineral, limestone and gypsum and adds water to it to produce a needle bed of 1 to 10 μm by hydrocuring reaction. The crystal, Ettringite, is produced. In particular, the addition of gypsum consumes a large amount of pore water to promote the hydration reaction, which shortens the condensation time and promotes the hydration reaction. As a result, more ethrinite is produced, thereby forming a hardened body having excellent water resistance. .
또한, 본 발명에 의한 방수공법은 크링커(3CaO·3Al2O3·CaSO4)에 함유된 칼륨성분은 표1 및 표2에 나타나 있는 것처럼 불안전한 알카리인 K2O로 존재하는 것이 아니고 수용성황산염으로 중성염인 2CaSO4·K2SO4로 존재하여 고알카리(PH12∼13)에서 저알칼리화(PH10)시킨 혼화제인 바, 부직포의 강알카리에 의한 열화로부터 보호될 수 있도록 하므로써 높은 강도가 유지될 수 있는 효과도 있다.In addition, in the waterproofing method according to the present invention, the potassium component contained in the clinker (3CaO · 3Al 2 O 3 · CaSO 4 ) is not present as K 2 O, which is an unstable alkali, as shown in Tables 1 and 2, and is a water-soluble sulfate. It is a mixture of high alkali (PH12 ~ 13) and low alkali (PH10), which is present as a neutral salt, 2CaSO 4 · K 2 SO 4 , so that high strength can be maintained by protecting it from deterioration due to strong alkali of nonwoven fabric. There is also an effect.
그밖에도, 본 발명에 의한 방수공법은 크링커(3CaO·3Al2O3·CaSO4)를 주성분으로 하는 도포용세라믹고화혼화제(#4200)가 물외의 개량량과 첨가제에 혼합되어 우수한 접착성, 수밀성, 내약품성 및 고강도의 물성을 가지는 혼화제를 얻을 수 있는 바, 내구성이 뛰어난 방수층을 시공할 수 있는 효과도 있다.In addition, in the waterproofing method according to the present invention, a ceramic ceramic admixture (# 4200) having a clinker (3CaO · 3Al 2 O 3 · CaSO 4 ) as a main component is mixed with an improvement amount and additives other than water to provide excellent adhesion and water tightness. In addition, since a admixture having chemical resistance and high strength physical properties can be obtained, there is also an effect that a waterproof layer having excellent durability can be constructed.
