PRECAST CONCRETE MEMBER AND MANUFACTURING METHOD OF PRECAST CONCRETE MEMBER
To provide a precast concrete member that can restrain reinforcing-bar rust while reducing a discharge amount of carbon dioxide with relatively low cost.SOLUTION: A precast concrete member 1 has: a plurality of main reinforcing-bars 2; a plurality of shear auxiliary reinforcements 3 placed around the main reinforcing-bar 2; a plurality of main reinforcing-bar embedded parts 8 formed with mortar and embedding the main reinforcing-bar 2; and a precast concrete body 9 formed with low alkali concrete with lower alkalinity than mortar and embedding the main reinforcing-bar embedded parts 8 and the shear auxiliary reinforcements 3.SELECTED DRAWING: Figure 1
【課題】二酸化炭素の排出量を削減しつつ、鉄筋の錆びを抑制できる比較的安価なプレキャストコンクリート部材を提供する。【解決手段】プレキャストコンクリート部材１は、複数の主筋２と、主筋２の周りに配置された複数のせん断補強筋３と、モルタルによって形成され、主筋２を埋設する複数の主筋埋設部８と、モルタルよりも低いアルカリ性を有する低アルカリコンクリートによって形成され、主筋埋設部８及びせん断補強筋３を埋設するプレキャストコンクリート本体９とを有する。【選択図】図１
