In this report, the history of stipulations relating to grading of fine aggregates was investigated. In the course of survey, great influence of ASTM standards on the stipulations in Japan was verified. But some cases different from ASTM standards were recognized. And it was found that the history of revision was a little different among the organizations preparing the stipulations or the kinds of fine aggregate. As for the present stipulations, it is thought to be established not only on the ideal grading curve theory, but also on the actual state of grading of fine aggregates.
