Zusammenfassung:The present invention relates to a method for manufacturing an upcycle public facility using ultrahigh performance concrete and waste plastics, which comprises the steps of: (a) manufacturing an installing formwork for manufacturing the public facility; (b) curing the ultrahigh performance concrete reinforced with steel fibers after forming the concrete in the formwork; (c) dismantling the formwork from a surface of the manufactured facility; and (d) trimming the surface of the facility. By using a rebar free method, the public facility can be manufactured with the strength of ultrahigh performance concrete, and waste plastic is added to realize upcycling. The surface can be subjected to water-repellent treatment to achieve excellent anti-ultraviolet durability, freeze-thawing resistance, salt resistance, and corrosion resistance. In addition, an eco-friendly public facility can be manufactured since no organic chemical product is used. 본 발명은 초고성능 콘크리트와 폐플라스틱을 이용한 업싸이클 공공시설물의 제조방법에 관한 것으로, (a) 공공시설물 제작용 거푸집을 제작하여 설치하는 단계와; (b) 강섬유로 보강된 초고성능 콘크리트를 상기 거푸집에 타설한 후 양생하는 단계와; (c) 제작된 공공시설물의 표면으로부터 상기 거푸집을 해체하는 단계와; (d) 상기 공공시설물의 표면을 다듬는 단계로 구성됨으로써, 철근 무배근 공법을 활용하여 초고성능 콘크리트의 강도만으로 공공시설물을 제조할 수 있되 폐플라스틱을 첨가하여 업사이클을 구현하고, 표면을 발수처리하여 항자외선 내구성, 동결융해 저항성, 내염해성, 내부식성이 우수한 특성을 구현할 수 있는 한편, 유기화학제품을 전혀 사용하지 않아 친환경 공공시설물을 제조할 수 있는 효과가 있다.
