METHOD FOR PRODUCING FINE AGGREGATE
To provide a method for producing a fine aggregate with high productivity when producing the fine aggregate that contains a copper slag partially as the fine aggregate, the copper slag being dispersed uniformly.SOLUTION: This invention relates to a method for producing a fine aggregate that contains a copper slag partially as the fine aggregate, including: a weighing step S1 of weighing each of sea sand, crushed sand, lime, and copper slag, as fine aggregate materials so that a copper slag-mixing rate (%) in the fine aggregate is a predetermined rate; and a basic mixing step S2 of sequentially mixing the fine aggregate materials to obtain the fine aggregate. In the basic mixing step S2, at first, a total amount of copper slag is mixed with at least one of sea sand, crushed sand, lime, and copper slag in the same amount as that of copper slag, and then is sequentially mixed with the residual fine aggregate materials.SELECTED DRAWING: Figure 1
【課題】銅スラグを細骨材の一部として含有する細骨材を製造するに際して、高い生産性で、その銅スラグが均一に分散している細骨材を製造することができる方法を提供する。【解決手段】本発明は、銅スラグを細骨材の一部として含有する細骨材を製造する方法であって、細骨材材料としての、海砂と、砕砂と、石灰と、銅スラグとを、細骨材中の銅スラグ混合率（％）が所定割合となるようにそれぞれを秤量する秤量工程Ｓ１と、細骨材材料を順次混合して細骨材を得る基礎混合工程Ｓ２と、を有する。そして、基礎混合工程Ｓ２では、最初に、銅スラグの全量と、海砂、砕砂、及び石灰から選ばれる１種のその銅スラグの量と同量とを混合し、その後、残余の細骨材材料を順次混合する。【選択図】図１
