Abstract
In case of use for recycled coarse aggregates produced from demolished concrete, a large volume of fine aggregate is generated. To use the fine aggregate effectively and safely, it is required to understand the leaching characteristics of Cr(VI) leached from the fine aggregate, and to execute a measurement to reduce Cr(VI) leached when the volume of Cr(VI) leached exceeds the limit of soil environmental standard.
