METHOD FOR PRODUCING HEAVYWEIGHT CONCRETE STRUCTURE, AND THE HEAVYWEIGHT CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a method for producing a heavyweight concrete structure, in which the heavyweight concrete structure having sufficient weight can be produced.SOLUTION: The method for producing a heavyweight concrete structure comprises the steps of: preparing a heavyweight mixture which contains 0.1-5.0 vol% of a metal fiber, 40-80 vol% of aggregate having 2.5-5.0 g/cmdensity, cement and water; preparing a lightweight mixture which contains other aggregate, cement and water and has the weight per unit volume smaller than that of the prepared heavyweight mixture; transporting the prepared heavyweight mixture and the prepared lightweight mixture respectively to the vicinity of an execution site; and injecting the transported heavyweight mixture and the transported lightweight mixture respectively to the execution site.SELECTED DRAWING: None
【課題】充分に重量がある重量コンクリート構造物を製造することができる製造方法を提供すること等を課題とする。【解決手段】0.1体積%以上5.0体積%以下の金属繊維と40体積%以上80体積%以下の密度2.5g/cm3以上5.0g/cm3以下である骨材とセメントと水とを含む重量混合物と、骨材とセメントと水とを含み且つ前記重量混合物よりも単位体積当たりの重量が小さい軽量混合物とをそれぞれ作製し、前記重量混合物と前記軽量混合物とをそれぞれ施工箇所付近に移送し、移送した前記重量混合物及び前記軽量混合物をそれぞれ施工箇所に注入することで重量コンクリート構造物を製造する。【選択図】なし
