CONCRETE COMPOSITION, AND HARDENED CONCRETE
To provide a concrete composition having excellent fluidity in a fresh state, capable of producing hardened concrete excellent in compression strength, flexural strength, and explosion fracture resistance, and hardened concrete excellent in compression strength, flexural strength, and explosion fracture resistance.SOLUTION: The concrete composition comprises water, cement, fine aggregate, coarse aggregate of an absolute volume of from 150 to 300 L/m, a deformed steel fiber having deformed parts, and a straight steel fiber free of a deformed part, with the ratio of the content of the deformed steel fiber relative to that of the straight steel fiber (deformed steel fiber:straight steel fiber) being from 1:0.5 to 1:2 on volume basis.SELECTED DRAWING: None
【課題】フレッシュ状態の流動性が良好であり、圧縮強度、曲げ強度及び耐爆裂性に優れるコンクリート硬化体が得られるコンクリート組成物、並びに、圧縮強度、曲げ強度及び耐爆裂性に優れるコンクリート硬化体を提供する。【解決手段】水と、セメントと、細骨材と、絶対容積が１５０Ｌ／ｍ３〜３００Ｌ／ｍ３の粗骨材と、変形部がある変形型鋼繊維と、変形部がない直線型鋼繊維と、を含有し、前記変形型鋼繊維と前記直線型鋼繊維との含有量比（変形型鋼繊維：直線型鋼繊維）が容量基準で１：０．５〜１：２である、コンクリート組成物。【選択図】なし
