To provide a coarse aggregate that can further improve compressive strength and tensile strength of concrete.SOLUTION: A metallic coarse aggregate for concrete 1A includes a plurality of spherical portions 3, and an annular portion 5 protruding from surfaces of the spherical portions 3 so as to surround the outer peripheries of the spherical portions 3. The width of the coarse aggregate in a connection portion of the spherical portions 3 on the plane formed by the outer edge of the annular portion 5 is equal to or greater than the minimum diameter of the spherical portions 3.SELECTED DRAWING: Figure 1A
【課題】コンクリートの圧縮強度と引張強度をより一層向上させることができる粗骨材を提供する。【解決手段】複数の球状部３と、複数の球状部３の外周を囲むように球状部３の表面から突出した環状部５とを有する金属製のコンクリート用粗骨材１Ａであって、環状部５の外縁で形成される面において球状部３同士の連結部における粗骨材の幅が球状部３の最小径以上である。【選択図】図１Ａ
