Description
본 발명은 폭열 저항성을 향상시킨 하이브리드 복합섬유를 포함하는 철골 모듈러 커넥터용 초고성능 섬유보강 시멘트계 복합재료 조성물 및 이를 이용한 시공방법에 관한 것으로서, 보다 상세하게는 건축물, 특정적으로 철골 모듈러 건축물에 적용할 경우 고강도이면서도 폭열 저항성을 향상시키고, 표면성능 및/또는 작업성이 좋은 철골 모듈러 커넥터용 초고성능 섬유보강 시멘트계 복합재료 조성물 및 이를 이용한 시공방법에 관한 것이다.The present invention relates to an ultra-high-performance fiber-reinforced cement-based composite material composition for steel modular connectors containing hybrid composite fibers with improved thermal resistance and a construction method using the same. More specifically, it relates to buildings, and specifically to steel modular buildings. The present invention relates to an ultra-high-performance fiber-reinforced cement-based composite material composition for a steel modular connector that has high strength yet improves resistance to detonation, has good surface performance and/or workability, and a construction method using the same.
건축재료는 기본적으로 시공이 편리하고 제작 및 시공에 있어 큰 비용을 들이지 않을 것을 요구할 뿐 아니라, 건축물에서 사용될 부분에 따라 각기 다른 성능이 요구되는데, 지붕재 및 외벽재, 방수층을 보호하는 보호판의 경우 시공의 편의를 위해 얇으면서도 향상된 구조성능, 내충격성 및 방수성을 지니며, 부착이 용이한 건축재료가 요구되고 있다.Building materials are not only required to be convenient for construction and not cost a lot of money in manufacturing and construction, but also require different performance depending on the part to be used in the building. In the case of roofing materials, exterior wall materials, and protective plates that protect the waterproof layer, the construction cost is very high. For convenience, building materials that are thin yet have improved structural performance, impact resistance and waterproofing, and are easy to attach are required.
또한, 철골 커넥터는 통상 철강 등으로 제조하여 용접 방식에 의해 접합하여 사용하고 있으나, 열에 의해 변형이 생기고 작업성이 떨어지는 문제점이 있다.In addition, steel connectors are usually manufactured from steel and used by joining them by welding, but there is a problem in that they are deformed by heat and workability is poor.
일반적으로 모르타르, 콘크리트 및 숏크리트와 같은 시멘트재(이하 "콘크리트" 라고 약칭한다)에 발생하는 초기 미세균열은 구조성능에 큰 영향을 미치지 않지만, 투수성을 증가시켜 이의 내구성능을 저하시키며, 내구 성능저하는 구조물의 파괴를 촉진시키는 원인이 된다. 따라서 콘크리트는 균열 발생이 억제되어야 적절한 내구 성능을 확보한다.In general, initial microcracks that occur in cement materials such as mortar, concrete, and shotcrete (hereinafter abbreviated as "concrete") do not have a significant effect on structural performance, but increase permeability and reduce durability performance. Deterioration causes accelerated destruction of structures. Therefore, in concrete, crack occurrence must be suppressed to ensure appropriate durability.
이러한, 성능 확보를 위해 보강 섬유들이 첨가된 콘크리트가 개발되고 있다. 콘크리트를 비롯한 시멘트 복합체에 단섬유를 보강재로 사용하는 목적은 건조수축으로 인한 균열을 제어하기 위한 것뿐만이 아니라 시멘트 복합체의 단점인 낮은 인장강도, 휨강도 등을 개선하여 취성적인 파괴를 억제함에 있다.To ensure such performance, concrete with reinforcing fibers added is being developed. The purpose of using short fibers as a reinforcing material in cement composites, including concrete, is not only to control cracks due to drying shrinkage, but also to suppress brittle fracture by improving the low tensile strength and bending strength, which are shortcomings of cement composites.
일반적으로 시멘트계 복합재료는 휨강도 및 인장강도가 작아 균열이 발생하기 쉽고, 압축강도가 높을수록 취성적으로 파괴되는 특성이 있다.In general, cement-based composite materials have low bending and tensile strengths, so they are prone to cracking, and the higher their compressive strength, the more brittle they are.
이에, 이를 극복하기 위하여 초고성능 섬유보강 시멘트계 복합재료(Ultra High Performance Fiber-Reinforced Cementitious Composites; UHPC)가 사용되고 있는바, 이는 시멘트, 실리카퓸, 충전재, 골재, 고성능 감수제 및 강섬유 등을 사용하여 100 내지 200MPa 수준의 압축강도, 30 내지 60MPa 수준의 휨강도 및 10 내지 20MPa 수준의 인장강도를 갖으며 취성적으로 파괴되지 않고 높은 인성을 갖는다.Therefore, in order to overcome this, ultra-high performance fiber-reinforced cementitious composites (UHPC) are being used, which use cement, silica fume, fillers, aggregates, high-performance water reducing agents, and steel fibers, and It has a compressive strength of 200 MPa, a bending strength of 30 to 60 MPa, and a tensile strength of 10 to 20 MPa, and is not brittle and has high toughness.
이러한 초고성능 섬유보강 시멘트계 복합재료는 일반적인 시멘트계 복합재료와 비교하여 상당히 높은 역학적 성능을 갖는 것을 특징으로 하지만, 대체로 약 20℃ 정도의 상온에서 1 내지 3일 동안 습윤양생을 실시한 다음, 60 내지 120℃ 정도의 고온에서 증기양생을 실시하여야 하는 복잡한 양생과정을 필요로 하는 문제점이 있다.These ultra-high-performance fiber-reinforced cement-based composite materials are characterized by significantly higher mechanical performance compared to general cement-based composite materials, but are generally wet cured for 1 to 3 days at room temperature of about 20 ℃ and then cured at 60 to 120 ℃. There is a problem that requires a complex curing process that requires steam curing at a relatively high temperature.

[실 험][Experiment]
실시예에 따라 제조된 조성물을 물과 혼합하여 콘크리트를 제조한 후 기계적 물성, 예를 들면 폭열 저항성, 압축강도, 휨강도 등을 측정하였다.The composition prepared according to the example was mixed with water to prepare concrete, and then the mechanical properties, such as bursting resistance, compressive strength, and bending strength, were measured.
여기서, 상기 폭열 저항성은 제조된 콘크리트를 1,080℃의 온도에서 3시간 동안 내화시험하여 육안관찰하였으며, 시험방법은 KS F 2257-1(2019년 준용)를 사용하였다.Here, the thermal resistance was visually observed by subjecting the manufactured concrete to a fire resistance test at a temperature of 1,080°C for 3 hours, and KS F 2257-1 (applied in 2019) was used as the test method.
그 결과를 표 1 및 도 1로 나타냈다.The results are shown in Table 1 and Figure 1.
표 1에 나타난 바와 같이, 실시예들에 따라 제조된 철골 모듈러 커넥터용 초고성능 섬유보강 시멘트계 복합재료 조성물은 폭열 저항성이 좋고 압축강도 및 휨강도가 초고성능 섬유보강 시멘트계 복합재가 요구하는 물성을 충분히 만족하는 것으로 나타났다.이상에서 설명한 바와 같이, 본 발명이 속하는 기술 분야의 당업자는 본 발명이 그 기술적 사상이나 필수적 특징을 변경하지 않고서 다른 구체적인 형태로 실시될 수 있다는 것을 이해할 수 있을 것이다. 그러므로 이상에서 기술한 실시예는 모두 예시적인 것이며 한정적인 것이 아닌 것으로서 이해해야만 한다. 본 발명의 범위는 상기 상세한 설명보다는 후술하는 특허청구범위의 의미 및 범위 그리고 그 등가개념으로부터 도출되는 모두 변경 또는 변형된 형태가 본 발명의 범위에 포함되는 것으로 해석되어야 한다.As shown in Table 1, the ultra-high-performance fiber-reinforced cement-based composite material composition for steel modular connectors manufactured according to the examples has good burst resistance and the compressive strength and flexural strength sufficiently satisfy the physical properties required by the ultra-high-performance fiber-reinforced cement-based composite. As described above, a person skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. Therefore, all embodiments described above should be understood as illustrative and not restrictive. The scope of the present invention should be construed as including all changes or modified forms derived from the meaning and scope of the claims described below and their equivalent concepts rather than the detailed description above.
