친환경 고무아스팔트와 이지시트를 이용한 복합방수공법{Complex waterproofing method using environment-friendly rubberized asphalt and easy-sheet}Complex waterproofing method using environment-friendly rubberized asphalt and easy-sheet}
본 발명은 친환경 고무아스팔트와 이지시트를 이용한 복합방수공법에 관한 것으로, 특히, 방수 시공면에 시공되는 방수층이 현장에서 한 장의 시트로 조성될 수 있게 하여 시트방수공법에서 발생하는 접합부의 터짐, 누수 등의 문제점이 원천적으로 차단되게 함과 동시에 도막방수공법에서 방수층의 균일한 두께 형성이 어렵다는 단점을 해소하여 누구나 시공을 하여도 시공이 간편하게 이루어질 수 있게 하고, 시공 후 방수층이 경화되지 않은 상태에서도 작업자가 방수층 위에서 후속 공정을 실시될 수 있도록 하여 방수층도 보호하면서 시공기간도 단축시킬 수 있게 하는 친환경 고무아스팔트와 이지시트를 이용한 복합방수공법에 관한 것이다.The present invention relates to a composite waterproofing method using an eco-friendly rubber asphalt and easy sheet. In particular, a waterproof layer applied on the waterproofing surface can be formed into a single sheet at the site, so that the joints generated by the sheet waterproofing method are bursting and leaking. It prevents problems such as fundamentally, and at the same time eliminates the disadvantage that it is difficult to form a uniform thickness of the waterproof layer in the coating waterproofing method, so that the construction can be easily performed by anyone, and even if the waterproof layer is not cured after construction, the worker It relates to a composite waterproofing method using eco-friendly rubber asphalt and easy sheet, which allows the subsequent process to be carried out on the waterproof layer to protect the waterproof layer and shorten the construction period.
콘크리트 구조물에는 정적, 동적 하중에 의한 휨 모멘트나 진동이 발생하여 균열이 일어나며 중성화 및 노화에 의한 박리가 발생한다.In concrete structures, bending moments or vibrations occur due to static and dynamic loads, causing cracks, and delamination due to neutralization and aging.
또한, 빗물 등은 콘크리트 표면에 틈이나 균열을 발생시킴과 동시에, 그 틈새로 침투하여 철근을 부식시켜 콘크리트의 균열을 촉진하며 콘크리트에 생긴 균열은 건축 토목 구조물의 수명을 단축시키는 원인이 된다.In addition, rainwater or the like creates cracks or cracks on the concrete surface, and at the same time penetrates into the cracks and corrodes reinforcing bars to promote cracks in concrete, and cracks in concrete shorten the life of civil engineering structures.
현재 국내 대표적인 방수공법은 시공방식에 따라 시트방수공법, 도막방수공법, 시트와 도막을 병합한 복합방수공법이 있다.Currently, representative waterproofing methods in Korea include the sheet waterproofing method, the coated film waterproofing method, and the composite waterproofing method in which the sheet and the coating film are combined according to the construction method.
도막방수공법의 경우 액상을 여러 번 도포한 후 경화시켜 방수층 형성하는 공법으로, 시공성은 매우 좋으나 일정한 두께의 방수층을 형성하지 못하며 도막 두께가 얇은 부위에서는 콘크리트의 균열에 의한 파단 현상이 빈번하게 발생하며, 콘크리트 모체에서 발생되는 수증기 압력에 의한 부풀음(도 1), 꽈리(도 2), 기포 등의 현상이 자주 발생하여 미세한 누수의 원인이 되며, 중심기재로는 보강재(유리섬유, 부직포) 등을 사용하나 보강재까지 흡수력의 문제, 접합성의 불일치, 치수안정성의 문제로 인한 시공상의 어려움이 있다. In the case of the coating waterproofing method, it is a method of forming a waterproof layer by applying a liquid several times and then curing. The workability is very good, but a waterproof layer of a certain thickness cannot be formed, and fractures due to cracks of concrete frequently occur in areas with a thin coating layer. , Puffiness (Fig. 1), swelling (Fig. 2), bubbles, etc. due to the steam pressure generated from the concrete matrix often occur, causing microscopic leakage, and reinforcing materials (glass fiber, non-woven fabric) as the central base material Even though it is used, there are difficulties in construction due to the problem of absorption power, inconsistency in bonding, and dimensional stability.
시트방수공법은 합성고무나 합성수지 또는 개량아스팔트를 주원료로 만든 방수시트를 콘크리트에 부착하여 방수층을 형성하는 공법으로, 기 제작된 방수시트를 토오치(Torch)등의 열융착이나 접착제를 이용하여 콘크리트 바탕면에 방수시트를 부착하여 시공하는 방수공법으로 제품이 규격화되어 있어 일정한 두께로 방수층을 형성할 수 있으므로 균일한 품질관리를 얻을 수 있으며, 내수성, 내약품성, 균열저항성이 우수하며 시공이 간단하다는 장점이 있다.The sheet waterproofing method is a method of forming a waterproof layer by attaching a waterproof sheet made of synthetic rubber, synthetic resin or modified asphalt as the main raw material to concrete to form a waterproof layer, and the previously manufactured waterproof sheet is applied to concrete using heat fusion such as Torch or an adhesive. It is a waterproofing method in which a waterproof sheet is attached to the base surface, and the product is standardized and a waterproof layer can be formed with a certain thickness, so uniform quality control can be obtained, and it is excellent in water resistance, chemical resistance, crack resistance, and construction is simple. There is an advantage.
그러나, 방수시트를 시공할 때는 시트 접합부(이음부)를 열융착 방식으로 접착시키는데, 방수시트에 토오치를 사용하여 접착시켜 시공하기 때문에 시트에 열이 과도하게 전달되었을 때에는 시트 표면이 손상되거나 변형되고, 또한 미열이 가해진 부분은 용융되지 않은 상태로 미접착 부분이 생기게 되어 접착력이 약화되게 되므로, 결국에는 들뜸 및 박리 등의 하자가 발생하여 누수가 발생되는 문제점이 있으며, 또한, 아스팔트만으로 구성된 방수시트는 혹한기에 시공하는 동안 또는 시공후에 시트의 유연성이 떨어져 부러지거나, 갈라지는 현상이 발생하며, 하절기 시에는 시트에 함침된 방수제가 녹아내려 방수효과가 감소되어 방수층의 파단으로 이어진다.However, when installing the waterproof sheet, the sheet joints (joints) are bonded in a heat-sealing method.Because the waterproof sheet is bonded with a torch, the surface of the sheet is damaged or deformed when excessive heat is transmitted to the sheet. In addition, since the part to which the slight heat was applied is not melted and the adhesive strength is weakened, there is a problem in that water leakage occurs due to defects such as lifting and peeling in the end. During or after construction during or after construction in cold weather, the sheet is broken or cracked, and in summer, the waterproofing agent impregnated in the sheet melts, reducing the waterproofing effect, leading to breakage of the waterproofing layer.
또한, 복합방수공법의 경우 시트와 도막을 2중으로 처리하여 안정성을 확보하는 장점을 지니고 있으나 재료비, 시공비가 매우 높으며 시공성이 복잡하여 숙련공이 많이 필요하고 시트층과 도막층의 접합 불일치로 박리, 조인트 연결부가 파단되는 경우가 빈번하게 발생하여 새로운 공법을 갈망하고 있다.In addition, in the case of the composite waterproofing method, it has the advantage of securing stability by treating the sheet and the coating film in duplicate, but the material cost and construction cost are very high, and the workability is complicated, so many skilled workers are required. The connection part is broken frequently, and a new construction method is desired.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 도막방수공법에 시트방수공법이 접목될 수 있게 하되, 시공 시 1회의 도포만으로 도막방수재가 경화되는 짧은 시간에 두께가 형성되도록 하기 위하여 방수층이 형성되지 않은 편직물인 이지시트가 시공면에 포설된 후 이 이지시트에 도포된 도막방수재가 편직물인 이지시트에 함침되면서 이지시트에 의해 소망하는 도막의 두께가 형성되도록 하여 이음매나 접합부가 없이 방수층이 형성될 수 있게 하고, 특히, 접합부 없이 형성된 방수층이 완전히 경화되지 않은 상태에서도 후속으로 공정을 실시하는 과정에서 작업자 등에 의하여 방수층이 훼손되거나 파손되는 것을 방지하여 안정된 방수층 형성이 유도되게 하고 작업시간 및 시공기간을 단축시킬 수 있게 하는 이지시트 및 친환경 고무아스팔트와 이지시트를 이용한 복합방수공법을 제공하는 데 그 목적이 있다.The present invention has been conceived to solve the above problems, and allows the sheet waterproofing method to be combined with the coating waterproofing method, but in order to form a thickness in a short time when the coating waterproofing material is cured with only one application during construction, a waterproofing layer is provided. After the unformed Knitted Easy Sheet is laid on the construction surface, the coating waterproofing material applied to this Easy Sheet is impregnated into the Knitted Easy Sheet so that the desired thickness of the coating is formed by the Easy Sheet, so that the waterproof layer is formed without any joints or joints. In particular, even when the waterproof layer formed without the joint is not completely cured, the waterproof layer is prevented from being damaged or damaged by workers during the subsequent process, so that the formation of a stable waterproof layer is induced, and the working time and construction Its purpose is to provide an easy sheet that can shorten the period and a composite waterproofing method using eco-friendly rubber asphalt and easy sheet.

The thickness (2.1mm ~ 3mm) has the advantage that it can be formed through the mixing ratio of the hardener and the liquid asphalt waterproofing material, and by installing an easy sheet over the entire construction surface and applying the waterproofing material, a waterproof layer without joints can be formed. Through this advantage, it has the effect of solving problems such as peeling and detachment of the joints and joints that occur after waterproof construction due to poor work of joints and joints as in the prior art.
그리고, 종래 도막방수공법에서 도막방수층 형성 후 자외선에 노출된 상태로 도막층이 경화되면서 발생하는 기포나 꽈리 및 방수막이 터지는 현상은 통기성이 뛰어난 이지시트에 의하여 기포발생의 우려를 해결하여 안정적인 도막층의 형성을 유도할 수 있으며, 특히, 시공 현장에서 한 장의 방수시트로 방수층을 형성한 것과 같은 효과를 얻을 수 있게 됨으로써, 종래 일정한 두께의 방수층 형성, 이음매 발생 및 파단, 방수층의 파단, 기포, 꽈리 등 우려되는 모든 문제점을 동시에 해결할 수 있게 되어 향후의 하자발생이 최소화되어 건물수명의 연장에 의한 제반적인 비용의 절감효과를 얻도록 하는 효과를 가진다.In addition, in the conventional coating waterproofing method, the phenomenon of bubbles or cracks and the bursting of the waterproofing film that occurs when the coating layer is cured in a state exposed to ultraviolet rays after the formation of the coating waterproofing layer is solved by the concern of bubble generation by the excellent ventilation easy sheet. The formation of a waterproof layer can be induced, and in particular, by obtaining the same effect as that of forming a waterproof layer with a single waterproof sheet at the construction site, the conventional waterproof layer of a certain thickness is formed, seams are generated and broken, the break of the waterproof layer, air bubbles, and tears. It is possible to solve all the problems of concern at the same time, minimizing the occurrence of defects in the future, and thus has the effect of reducing overall cost by extending the life of the building.
또한, 상기 이지시트에 함침됨으로써, 형성된 방수층이 완전경화되지 않은 상태에서 상기 방수층의 상부에 합성고무계 보호재를 도포하여 신속하게 경화시킴으로써, 방수층이 보호되도록 하여 작업자가 그 상부를 보행하면서 후속으로 진행될 공정을 실시한다 하더라도 방수층이 보호될 수 있게 되어 작업시간 및 시공기간을 단축할 수 있는 효과를 가진다.In addition, by being impregnated in the easy sheet, a synthetic rubber-based protective material is applied on the upper part of the waterproof layer and rapidly cured while the formed waterproof layer is not completely cured, so that the waterproof layer is protected and the worker walks over the upper part of the process to be followed. Even if it is carried out, the waterproof layer can be protected, so that the working time and construction period can be shortened.

본 발명 친환경 고무아스팔트와 이지시트를 이용한 복합방수공법에서 중요한 구성요소인 이지시트의 구성을 살펴보면 다음과 같다.Looking at the configuration of the easy sheet, which is an important component in the composite waterproofing method using the eco-friendly rubber asphalt and the easy sheet of the present invention.
본 발명의 이지시트는 폴리에틸렌(Polyethylene, PE)으로 이루어진 원사를 편직하여 이루어진 편직물로서, 편직이 완료됨과 동시에 180 ~ 220℃로 열처리 가공하여 폴리에틸렌(Polyethylene, PE)으로 이루어진 원사가 편직되면서 원사의 재질적 특성에 의하여 복원되려하는 복원력이 제거되게 하여 이지시트가 편평한 상태를 유지하게 하며, 편직된 상기 이지시트는 1㎡당 150 ~ 180g의 중량이 되도록 편직하는 것이 바람직하다.The easy sheet of the present invention is a knitted fabric made by knitting a yarn made of polyethylene (PE), and when the knitting is completed, the material of the yarn is knitted by heat treatment at 180 to 220°C and the yarn made of polyethylene (PE) is knitted. It is preferable that the easy sheet maintains a flat state by removing the restoring force to be restored by the appropriate characteristics, and the knitted easy sheet is preferably knitted to have a weight of 150 to 180 g per 1 ㎡.
한편, 본 발명에 따른 친환경 고무아스팔트와 이지시트를 이용한 복합방수공법은 방수시공을 하고자 하는 바탕면(100)의 이물질을 제거하고 세척하는 바탕면(100) 정리단계를 실시하고, 상기 바탕면(100) 정리단계에 의해 정리된 콘크리트 바탕면(100)에는 합성고무계 프라이머를 도포하여 프라이머층(102)을 형성하는 프라이머 도포단계를 실시한다.On the other hand, the composite waterproofing method using an eco-friendly rubber asphalt and easy sheet according to the present invention performs a step of arranging the base surface 100 to remove and clean foreign substances on the base surface 100 to be waterproofed, and the base surface ( 100) A primer application step of forming a primer layer 102 by applying a synthetic rubber-based primer to the concrete base surface 100 arranged by the arrangement step is performed.
그리고, 상기 프라이머 도포단계가 실시된 후, 상기한 이지시트를 바탕면(100)에 포설하는 이지시트 포설단계를 실시하는 바, 이때, 상기 이지시트를 포설하는 방법은 길이방향을 따라 하나의 이지시트만이 포설되게 한 후, 후술하게 될 방수재 도포단계에 의하여 도막방수재를 포설된 이지시트에 도포할 수도 있으며, 상기 이지시트를 길이방향을 따라 연장되도록 포설한 후, 측면 방향으로는 또 다른 이지시트를 연접하여 포설하되, 서로 오버랩(overlap)되도록 포설한 후, 후술하게 될 방수재 도포단계에 의하여 도막방수재를 포설된 이지시트 전체에 도포할 수도 있는 것으로, 상기한 이지시트 포설단계는 작업조건에 따라 선택적으로 채택할 수 있는 것이므로 본 발명은 여기에 한정되지 않고 다양하게 채택변경할 수 있다.And, after the primer application step is performed, the easy sheet laying step of installing the easy sheet on the base surface 100 is carried out. In this case, the method of laying the easy sheet is one easy sheet along the length direction. After allowing only the sheet to be laid, the coating waterproofing material may be applied to the laid easy sheet by a waterproofing material application step to be described later. After the easy sheet is laid to extend along the length direction, another easy It is possible to install the sheets by connecting them, but after laying them so that they overlap each other, the coating waterproofing material may be applied to the entire laid easy sheet by a waterproofing material application step to be described later. Therefore, the present invention is not limited thereto and can be variously adopted and changed.
상기한 바와 같이 이지시트 포설단계에 의하여 이지시트가 바탕면(100)에 포설되면, 상기 바탕면(100)에 포설된 이지시트에 액상의 아스팔트계 방수재와 경화제가 15 ~ 19kg : 100 ~ 200cc로 혼합된 도막방수재를 도포하여 이지시트에 도막방수재가 함침되게 하는 방수재 도포단계를 실시한다.As described above, when the easy sheet is installed on the base surface 100 by the easy sheet installation step, the liquid asphalt-based waterproofing material and the hardener are 15 ~ 19kg: 100 ~ 200cc in the easy sheet installed on the base surface 100. A waterproofing material application step is performed in which the mixed waterproofing material is applied and the waterproofing material is impregnated with the easy sheet.
여기서, 상기 아스팔트계 방수재는 1,000cps 이상의 점도와 600% 이상의 신장율을 가지며, 고형분이 80% 이상인 고무아스팔트인 것이 바람직하다.Here, the asphalt-based waterproofing material has a viscosity of 1,000 cps or more and an elongation of 600% or more, and is preferably a rubber asphalt having a solid content of 80% or more.
즉, 상기 이지시트는 도막방수재가 함침된 후 두께가 용이하게 형성되도록 하기 위하여 편직되면서 형성된 연결용 루프와 연결고리가 일정한 두께를 형성하면서 그 사이에 빈 공간이 형성되도록 한 것으로서, 아스팔트계 방수재의 점도가 1,000cps 이하일 경우 흐름성이 높아지므로, 이지시트에 함침된 도막방수재가 이지시트에 함침되는 함침률은 증가하지만, 상대적으로 고형분이 80% 이하로 조성되므로, 경화과정에서 수축하는 현상이 크게 발생하며, 이때, 이지시트에 함침된 도막방수재가 어느 한 방향으로 편중되게 수축될 경우 균일하게 두께가 형성되지 못할 수도 있으며, 특히, 계절, 기후, 작업환경에 따라 경화과정에서 수축되는 수축률이 크게 달라지게 되어 작업이 불편하게 이루어질 수 있는 단점이 발생하게 된다.That is, the easy sheet is made to form an empty space between the connecting loop and the connecting ring formed while being knitted to form a thickness easily after the coating waterproofing material is impregnated. If the viscosity is less than 1,000 cps, the flowability increases, so the impregnation rate at which the coating waterproofing material impregnated in the easy sheet is impregnated into the easy sheet increases, but since the solid content is relatively composed of 80% or less, shrinkage during the curing process is greatly increased. At this time, if the coating waterproofing material impregnated in the easy sheet shrinks unevenly in one direction, the thickness may not be uniformly formed. In particular, the shrinkage rate that shrinks during the curing process is large depending on the season, climate, and work environment. As it becomes different, there is a disadvantage that the work may be uncomfortable.
따라서, 본 발명에서는 이지시트에 함침되는 도막방수재가 본 발명의 이지시트에 적합한 흐름성을 갖게 함과 동시에 이에 따라, 예측 가능한 수축률을 갖게 함으로써, 두께 형성이 용이하게 이루어지게 하면서 수축에 의한 두께의 편차가 배제되도록 아스팔트계 방수재의 점도가 1,000cps 이상으로 유지되게 하는 것이 바람직하다.Therefore, in the present invention, the coating waterproofing material impregnated in the easy sheet has a flowability suitable for the easy sheet of the present invention, and thus, has a predictable shrinkage rate, thereby facilitating the formation of the thickness and reducing the thickness due to shrinkage. It is desirable to maintain the viscosity of the asphalt waterproofing material at 1,000 cps or more so that deviations are excluded.
다시 말하면, 상기 아스팔트계 방수재인 고무아스팔트는 상기한 바와 같이 1,000cps 이상의 점도와 600% 이상의 신장율을 가지며, 고형분이 80% 이상이며, 이지시트에 함침되는 도막방수재는 상기한 아스팔트계 방수재와 경화제를 15 ~ 19kg : 100 ~ 200cc로 혼합하여 경화속도와 점도 및 흐름성이 작업에 적합하게 됨으로써, 두께 형성이 용이하게 이루어지게 하면서 수축에 의한 두께의 편차가 배제될 수 있게 되는 것이다.In other words, the asphalt-based waterproofing rubber asphalt has a viscosity of 1,000 cps or more and an elongation of 600% or more, as described above, and has a solid content of 80% or more, and the coating waterproofing material impregnated in the easy sheet contains the above asphalt-based waterproofing material and the hardener. 15 ~ 19kg: Mixing at 100 ~ 200cc makes the curing speed, viscosity, and flow properties suitable for work, so that thickness formation is facilitated and variations in thickness due to shrinkage can be excluded.

It blocks and plays a role of making the structure of the composition dense, and a surfactant, etc. can be used, and a silicone antifoaming agent that is chemically safe and has excellent effects can be used.
즉, 상기 소포제는 조성물 제조시 발생하는 기포를 제거하기 위한 첨가제로서 0.3 ~ 1 중량% 범위에서 사용하는 것이 바람직하다. 0.3 중량% 미만으로 사용하는 경우 기포제거가 어려워 조성물의 물성이 저하되며 1 중량%를 초과하여 사용할 경우 기포 제거 효과는 증대하지만 표면에 슬립성 부여로 상, 하부 조성물과의 접착성능이 저하된다.That is, the antifoaming agent is preferably used in the range of 0.3 to 1% by weight as an additive for removing air bubbles generated during the preparation of the composition. When used in an amount of less than 0.3% by weight, it is difficult to remove bubbles and the physical properties of the composition are deteriorated, and when used in excess of 1% by weight, the bubble removal effect increases, but the adhesion performance with the upper and lower compositions decreases due to the provision of slip properties on the surface.

상기 비반응성 희석제는 주제 전체 중량 100 중량%에 대하여 5 ~ 10 중량%를 함유되는 것이 바람직한데, 5 중량% 미만이면 점도 조절 및 부착성 향상의 효과가 거의 없으며, 10 중량%를 초과하면 경화가 지연되고 표면의 경도가 저하되는 단점이 있다.It is preferable that the non-reactive diluent contains 5 to 10% by weight with respect to 100% by weight of the total weight of the main material. If it is less than 5% by weight, there is little effect of controlling viscosity and improving adhesion, and if it exceeds 10% by weight, curing is performed. There is a disadvantage that it is delayed and the hardness of the surface decreases.
상기한 주제 조성물 중 탄산칼슘, 마그네슘 실리케이트, 실리카는 체질안료로서, 보호층(106)내의 기공을 충전시키고 경도, 도막 형성 등의 보완 및 광택을 조절하는 역할을 하며, 이들 중에서 선택된 하나 이상을 사용하여 양호한 도막 외관을 얻을 수 있음은 물론이고, 방청성을 향상시키고, 작업성 및 도막 형성의 효과를 높일 수는 것으로, 주제 전체 100 중량%를 기준으로 5 ~ 20 중량%를 첨가하며, 5 중량% 미만 첨가 시 적절한 색상 및 기계적 물성 보완의 효과를 나타낼 수 없고, 20 중량% 초과 첨가 시 효과상 증가가 없고 비경제적이며 일부 침전이 발생할 우려가 있다. Calcium carbonate, magnesium silicate, and silica among the above-described main compositions are extender pigments, filling the pores in the protective layer 106, supplementing hardness, film formation, etc., and adjusting gloss, and at least one selected from them is used. Thus, not only can a good coating film appearance be obtained, but also rust prevention properties can be improved, workability and the effect of coating film formation can be improved.5 to 20% by weight is added based on 100% by weight of the total body, and 5% by weight If it is added less than, the effect of supplementing the color and mechanical properties cannot be exhibited, and if it is added more than 20% by weight, there is no increase in effect, uneconomical, and there is a concern that some precipitation may occur.
한편, 합성고무계 보호재 중 경화제는 후술하게 될 모르타르와의 혼합 후 시공 시 합성고무계 보호재의 경화시간에 따라 혼합하여 사용된다.On the other hand, among the synthetic rubber-based protective materials, the curing agent is mixed and used according to the curing time of the synthetic rubber-based protective material during construction after mixing with a mortar to be described later.
그리고, 상기한 모르타르는 포틀랜드 시멘트 20 ~ 40 중량%, 블레인 분말도가 5,000~8,000㎠/g인 초미립 비정질 칼슘설포알루미네이트 10 ~ 20 중량%, 무수석고 5 ~ 10 중량%, 규사 30 ~ 60 중량%, 촉진제 0.1 ~ 2 중량%, 이산화티탄 0.1 ~ 2 중량%, 수축저감제인 에틸렌글리콜 0.1 ~ 2 중량%로 조성된다.In addition, the above-described mortar is Portland cement 20 to 40% by weight, ultrafine amorphous calcium sulfoaluminate 10 to 20% by weight with a blast powder of 5,000 to 8,000㎠/g, anhydrous gypsum 5 to 10% by weight, silica sand 30 to 60 It is composed of 0.1 to 2% by weight of accelerator, 0.1 to 2% by weight of titanium dioxide, and 0.1 to 2% by weight of ethylene glycol as a shrinkage reducing agent.
상기 모르타르 조성물 중 포틀랜드 시멘트는 KS에 규정된 것을 사용하는 것이 바람직하며, 일반 시중에 유통되는 시멘트를 사용할 수도 있다. 상기 포틀랜드 시멘트는 모르타르 조성물 전체 100 중량%를 기준으로 20 ∼ 40 중량%를 함유되는 것이 바람직하다.Among the mortar compositions, Portland cement is preferably used as specified in KS, and cement distributed in the general market may be used. It is preferable that the Portland cement contains 20 to 40% by weight based on 100% by weight of the total mortar composition.
상기 모르타르 조성물 중 비정질 칼슘설포알루미네이트는 무기질계 초속경 재료로서 물과 접촉할 때 순식간에 물과 반응하여 에트린가이트(Ettringite) 수화물을 생성함으로써, 시멘트와 혼합할 때 수일 혹은 수 십일에 얻어지는 일반 포틀랜드 시멘트의 압축강도를 수 시간 내에 얻을 수 있게 하며, 블레인 분말도가 5,000~8,000㎠/g인 초미립 비정질로서 모르타르 전체 100 중량%를 기준으로 10 ∼ 20 중량%를 함유되는 것이 바람직하다. 상기 칼슘설포알루미네이트의 함량이 10 중량% 미만이면 충분한 초기 강도 발현을 기대하기 어려우며, 20 중량%를 초과하면 강도발현은 우수하나, 작업성 및 경제성이 저하될 수 있다.In the mortar composition, amorphous calcium sulfoaluminate is an inorganic ultra-fast hard material, and when it comes into contact with water, it reacts with water in an instant to produce ethringite hydrate, which is obtained in several days or tens of days when mixed with cement. It is possible to obtain the compressive strength of Portland cement within a few hours, and it is preferable to contain 10 to 20% by weight based on 100% by weight of the total mortar as an ultrafine amorphous material having a blast powder of 5,000 to 8,000 cm2/g. If the content of the calcium sulfoaluminate is less than 10% by weight, it is difficult to expect sufficient initial strength expression, and if it exceeds 20% by weight, the strength is excellent, but workability and economy may be deteriorated.
상기 모르타르 조성물 중 무수석고는 초기강도 발현을 위하여 사용되는 것으로서, 무수석고의 함량이 증가하면 빠른 경화특성을 나타낸다. 상기 무수석고는 모르타르 조성물 100 중량%를 기준으로 5 ∼ 10 중량% 함유되는 것이 바람직하다. 상기 무수석고의 함량이 5 중량% 미만이면 초기강도 발현 효과가 미약할 수 있고, 10 중량%를 초과하면 작업성 및 내수성이 저하될 수 있다.In the mortar composition, anhydrite is used to express initial strength, and when the content of anhydrite is increased, it exhibits rapid hardening properties. It is preferable that the anhydrite is contained in an amount of 5 to 10% by weight based on 100% by weight of the mortar composition. If the content of the anhydrite is less than 5% by weight, the initial strength expression effect may be weak, and if it exceeds 10% by weight, workability and water resistance may be deteriorated.
상기 모르타르 조성물 중 규사는 강도 발현을 위해 사용되며, 서로 입자크기가 다른 규사를 첨가하여 공극률을 낮출 뿐만 아니라, 아크릴 수지와 EVA 수지와 혼합된 혼합규사를 사용하여 콘크리트의 압축강도를 증가시키고 방수 성능도 증대시키는 것이 바람직하다.In the mortar composition, silica sand is used to develop strength, and silica sand having different particle sizes is added to lower the porosity, and mixed silica sand mixed with acrylic resin and EVA resin is used to increase the compressive strength of concrete and waterproof performance. It is desirable to increase the degree.
단일 입자 사용보다 혼합 규사 사용시 공극률 적어 온도에 의한 열팽창, 수축현상이 현저히 줄어 크랙 발생이 줄어들며, 혼합규사 첨가로 피착면과의 접촉면적이 넓어져 부착 강도가 향상되고, 공극률을 현저히 줄여 수분(물) 이나 기타 화학적 침투성 등 저항성이 우수해 철근의 부식방지, 콘크리트 산화을 방지하여 콘크리트의 내구성이 향상된다. When mixed silica sand is used, the porosity is less when using mixed silica, so thermal expansion and shrinkage due to temperature are significantly reduced to reduce the occurrence of cracks.The addition of the mixed silica sand increases the adhesion strength by increasing the contact area with the adherend surface, and significantly reduces the porosity to reduce moisture (water ) Or other chemical permeability, etc., to prevent corrosion of reinforcing bars and to prevent concrete oxidation, thereby improving the durability of concrete.
상기 규사는 모르타르 조성물 전체 중량을 기준으로 30 중량% 이하 첨가 시 압축강도가 저하되고, 응결속도 빨라져 시공이 불편하며, 가격이 상승하고, 60 중량% 이상 첨가 시 연성저하로 작은 진동에도 깨지기 쉽고, 접착력 저하로 부착력이 현저 떨어진다. When the silica sand is added at 30% by weight or less based on the total weight of the mortar composition, the compressive strength is lowered, the condensation rate is accelerated, making construction inconvenient, and the price increases, and when added at least 60% by weight, it is easy to break even with small vibrations, The adhesion is significantly lower due to the decrease in adhesion.
상기 모르타르 조성물 중 촉진제는 건설현장에서 공기단축을 위한 기술경쟁력 확보방안으로 제시되며, 구조체 공사 및 마감공사 등에서 다양한 방안을 적용하여 공기 단축을 도모하기 위해 사용된다.In the mortar composition, the accelerator is suggested as a method of securing technical competitiveness for shortening the construction site, and is used to reduce the construction period by applying various measures in structure construction and finishing work.
상기 촉진제는 수용성 유기염인 Calcium fomate(Cf), Sodium acetate(Sa), Triethanolamine(TEA) 중 선택하여 많이 사용되며, 수용성 무기염이 유기염에 비해 상대적으로 경화촉진 효과가 우수하였으며, 사용량이 적은 범위 내에서는 수용성 무기염에 의한 C3S의 수화 반응 촉진 효과가 발현에 효과적이며, 모르타르 조성물 전체 100 중량%를 기준으로 0.1 ~ 2 중량%를 첨가하는 것이 바람직하다.The accelerator is widely used by selecting from water-soluble organic salts such as Calcium fomate (Cf), Sodium acetate (Sa), and Triethanolamine (TEA), and the water-soluble inorganic salt has a relatively superior curing accelerating effect compared to the organic salt, and the amount used is small Within the range, the effect of promoting the hydration reaction of C 3 S by the water-soluble inorganic salt is effective for expression, and it is preferable to add 0.1 to 2% by weight based on the total 100% by weight of the mortar composition.
상기 모르타르 조성물 중 이산화티탄은 무기계이고 비전도성인 금속 산화물로서 조성물간에 결합력을 강화시킨다. 또한 보호층(106)이 얇게 도포되더라도 보호층(106)의 기계적 성질을 향상시켜 보호층(106)의 내구성을 증대시키며, 모르타르 조성물 전체 100 중량%를 기준으로 0.1 중량% 미만 첨가 시 부착력이 저하되어 보호층(106)이 탈락되며 내구성이 저하되고, 함량이 2 중량% 초과인 경우에는 논-슬립(Non-slip)효과를 갖지 못하여 보호층(106)의 부착성이 저하되며 다른 물질의 함량을 감소시켜 가교밀도 등의 물성저하를 가져올 수 있다.Titanium dioxide in the mortar composition is an inorganic and non-conductive metal oxide that strengthens the bonding force between the compositions. In addition, even if the protective layer 106 is applied thinly, the mechanical properties of the protective layer 106 are improved to increase the durability of the protective layer 106, and adhesion is lowered when less than 0.1% by weight is added based on the total 100% by weight of the mortar composition. As a result, the protective layer 106 is removed and durability is reduced, and if the content is more than 2% by weight, the adhesion of the protective layer 106 is lowered and the content of other materials does not have a non-slip effect. It may reduce physical properties such as crosslinking density by reducing
