CONCRETE PAVEMENT CONSTRUCTION METHOD USING FOAM SHOTCRETE
The present invention relates to a concrete pavement construction method using foam shotcrete which uses: normal strength shotcrete that is produced by mixing normal concrete produced by a batch plant having a compressive strength of 21-30 MPa, transferred to a site and mixed with bubbles of 20-40% of the volume of the normal concrete, with a low-grade mixture material containing one or more of fly ash, fine slag powder and stone dust; and high-performance shotcrete that is produced by mixing the normal concrete with a high-grade mixture material containing one or more of silica fume, meta-kaolin, latex, polymer and a coloring material.
La présente invention concerne un procédé de construction de chaussée en béton qui utilise du béton mousse projeté. Ledit procédé utilise : du béton projeté à résistance normale qui est produit en mélangeant du béton normal, produit par une usine à production discontinue, qui possède une résistance à la compression de 21 à 30 MPa, transféré à un site et mélangé avec des bulles de 20 à 40 % du volume du béton normal, avec un matériau de mélange de faible qualité qui contient des cendres volantes, et/ou du laitier fin et/ou de la poudre de pierre ; et du béton projeté à hautes performances qui est produit en mélangeant le béton normal avec un matériau de mélange de haute qualité qui contient de la fumée de silice, et/ou du méta-kaolin, et/ou du latex, et/ou du polymère et/ou un matériau colorant.
본 발명은 배처플랜트에서 압축강도 21~30MPa의 보통콘크리트를 생산하여 현장 이송 후, 체적 대비 20~40%의 기포를 혼입하여 유동성을 증가시킨 상태에서 플라이애쉬나 슬래그미분말, 석분 중 어느 하나 또는 하나 이상을 혼합한 저급 혼합재료를 혼입하여 형성한 보통강도 숏크리트 및 실리카퓸과 메타카올린, 라텍스, 폴리머, 착색재료 중 어느 하나 또는 하나 이상을 혼합한 고급 혼합재료를 혼입하여 형성한 고성능 숏크리트로 콘크리트포장함으로, 시공비용 절감 및 고강도와 고내구성을 확보하여 유지관리를 용이하게 할 수 있는 기포숏크리트를 이용한 콘크리트포장 시공방법에 관한 것이다.
