PROBLEM TO BE SOLVED: To provide concrete using copper slag not generating material separation.SOLUTION: In this concrete using copper slag, which is concrete including cement, coarse aggregate and fine aggregate, the fine aggregate is constituted of copper slag and mountain sand having a coarse particle ratio of <2.75, and the ratio of the mountain sand to the whole fine aggregate is determined to be ≥43% in terms of the volume ratio, to put it in detail, in the range of 43%-50%. A synthetic coarse particle ratio of the copper slag and the sand is preferably ≤2.78, to put it in detail, in the range of 2.78-2.70. |
