Abstract

PURPOSE: Provided is a manufacturing method of amorphous alloy fiber-reinforced concrete which has low manufacturing cost, heat resistance and chemical stability by adding amorphous alloy fibers, being instead of carbon fibers, in mixing concrete. CONSTITUTION: The amorphous alloy fiber reinforced concrete is manufactured by adding 0.5-2%(based on the total volume) amorphous alloy fibers whose surfaces are corroded, being 30-60mm and 0.1mm in length and thickness, respectively, in mixing concrete, followed by pouring the mixture into a form and vibrational compacting and curing. The resultant concrete is excellent in toughness, elasticity, dimensional stability, and corrosion-resistance.

아몰퍼스 합금 섬유보강 콘크리트의 제조법 및 제품 {manufacturing method and production of amorphous alloy fiber reinforced concrete}Manufacturing method and product of amorphous alloy fiber reinforced concrete

콘크리트의 인장 저항 능력의 증대, 국부적 균열의 생성 및 성장을 억제하는 등 역학적 성질을 개선·보강하기 위해서 불연속적으로 단상인 섬유질 재료를 콘크리트에 넣은 섬유보강 콘크리트에는 혼입되는 섬유에 따라 강섬유보강 콘크리트, 유리섬유보강 콘크리트, 탄소섬유보강 콘크리트, 합성섬유보강 콘크리트 등으로 구분된다.In order to improve and reinforce mechanical properties such as increasing the tensile resistance ability of concrete, suppressing local crack formation and growth, fiber reinforced concrete in which discontinuous single-phase fibrous material is put into concrete, Glass fiber reinforced concrete, carbon fiber reinforced concrete, synthetic fiber reinforced concrete, etc.

그 중 탄소섬유는 역학적 특성, 내열성 및 화학적 안정성 등 역학적 성질이 유리섬유, 강섬유와 비교하여 우수한 성능을 지니고 있어 콘크리트의 보강섬유로서 국내외에서 많은 주목을 받고 있으나 고가이기 때문에 활용면에 있어 제약이 있다.Among them, carbon fiber has excellent performance compared to glass fiber and steel fiber because of its mechanical properties such as mechanical properties, heat resistance and chemical stability, and it has attracted much attention both at home and abroad as concrete reinforcing fiber, but it is expensive in terms of utilization. .

본 발명은 역학적 특성, 내열성 및 화학적 안정성 등 역학적 성질이 탄소섬유와 거의 유사하면서도 상대적으로 가격이 저렴한 아몰퍼스 합금 섬유를 혼입한 섬유보강 콘크리트이다. 우수한 역학적 성질을 지니면서도 저가로 공급할 수 있는 아몰퍼스 합금을 섬유로 이용하기 때문에 기존 탄소섬유가 고가이어서 적용되기 힘들었던 곳에 적용을 할 수 있어 콘크리트의 품질을 개선시키는 것은 물론 섬유보강 콘크리트의 활용영역을 크게 확대시킬 수 있다.The present invention is a fiber-reinforced concrete incorporating amorphous alloy fibers with relatively low mechanical properties such as mechanical properties, heat resistance and chemical stability, and relatively inexpensive. As it uses amorphous alloys that can be supplied at low cost with excellent mechanical properties as fibers, it can be applied where existing carbon fibers were expensive and difficult to apply, thereby improving the quality of concrete and greatly expanding the application area of fiber reinforced concrete. You can enlarge it.

본 발명은 콘크리트의 취성개선, 구조물의 균열발생 및 성장억제, 변형 등에 악영향을 미치는 장기변형특성을 개선한 고인성·고탄성, 치수안정성, 내식성 및 신뢰성 증진성능 등 기존의 섬유보강 콘크리트 중 가장 우수한 성능을 지닌 탄소섬유 보강콘크리트와 유사한 성능을 가진 아몰퍼스 합금 섬유보강 콘크리트의 제조법 및 제품에 관한 것이다. 본 발명에 따른 제조방법은 콘크리트 혼합시 부착성능의 향상을 위해 길이 30∼60mm, 두께 0.1mm 정도의 아몰퍼스 합금 섬유를 전체 용적의 0.5∼2.0%비율로 균일하게 혼입하여 거푸집에 타설한 후 진동다짐을 실시하여 성형한 섬유보강 콘크리트관한 것이다.The present invention is the most excellent performance among existing fiber reinforced concrete such as high toughness, high elasticity, dimensional stability, corrosion resistance and reliability enhancement performance that improved long-term deformation characteristics adversely affect the brittleness improvement, crack formation and growth inhibition, deformation of concrete The present invention relates to a method and a product for producing an amorphous alloy fiber reinforced concrete having a performance similar to that of a carbon fiber reinforced concrete. In the manufacturing method according to the present invention, in order to improve adhesion performance when mixing concrete, amorphous alloy fibers having a length of 30 to 60 mm and a thickness of about 0.1 mm are uniformly mixed at a ratio of 0.5 to 2.0% of the total volume and poured into formwork, followed by vibration. Fiber reinforced concrete tube formed by carrying out.
