| abstract | Hexavalent chromium in cement is fixed to the hydrate in the process of hydration, but when neutralized, the cement hydrate fixing hexavalent chromium is decomposed and hexavalent chromium is decomposed. In general, the larger the specific surface area, the greater the progress of neutralization and the greater the elution amount of trace components, so the waste concrete powder used after being crushed is neutralized. Providing a powder composition that can reduce the amount of hexavalent chromium eluted from waste concrete powder that has been neutralized to prevent the elution of hexavalent chromium after reuse. A Blaine specific surface area of 6000 cm 2 / g or more with respect to waste concrete powder 1-100 parts by removal of the coarse aggregate, preferably ground granulated blast furnace slag which has been adjusted to 6000~8000cm 2 / g 1~100 Part by weight, preferably 1 to 10 parts by weight, particularly preferably 2 to 5 parts by weight of the powder composition. The powder composition is used for recycled roadbed materials, recycled backing materials, recycled backfill materials, and the like. [Selection figure] None |
