To provide a concrete composition that has excellent workability with a thin layer and is excellent in strength development of initial term and a long term.SOLUTION: A concrete composition contains the cement, pozzolanic material, fine aggregate A having a particle size smaller than 2.5 mm and fine aggregate B having a particle size of 2.5 mm or larger and 10 mm or smaller, in which the content of the pozzolanic material is 3 to 34 pts.mass relative to 100 pts.mass of the cement, the total content of fine aggregate A and the fine aggregate B is 110 390 pts.mass relative to 100 pts.mass of the cement, and a mass ratio of the content of the fine aggregate B relative to a total of the fine aggregate A and the fine aggregate B ([content of the fine aggregate B (pts.mass)]/[the total content of the fine aggregate A and the fine aggregate B (pts.mass)] is 0.03 to 0.44.SELECTED DRAWING: None
【課題】薄層での施工性がよく、初期及び長期の強度発現性に優れるコンクリート組成物を提供すること。【解決手段】セメント、ポゾラン物質、粒径２．５ｍｍ未満の骨材Ａ及び粒径２．５ｍｍ以上１０ｍｍ以下の骨材Ｂを含み、ポゾラン物質の含有量が、セメント１００質量部に対し、３〜３４質量部であり、骨材Ａ及び骨材Ｂの合計の含有量が、セメント１００質量部に対し、１１０〜３９０質量部であり、骨材Ａ及び骨材Ｂの合計の含有量に対する骨材Ｂの含有量の質量比（［骨材Ｂの含有量（質量部）］／［骨材Ａ及び骨材Ｂの合計の含有量（質量部）］）が、０．０３〜０．４４である、コンクリート組成物。【選択図】なし
