Description
Summary:碩士 === 國立屏東科技大學 === 環境工程與科學系 === 93 === Solidification process has been widely used in the stabilization of Municipal solid waste such as fly ashes and hazardous sludge. In the past, solidified concrete has to pass the single axial strength test regulated by law, in order to enhance the anti-leaching ability of hazardous matters in solidified concrete. This study has tried to use radiation detection, that is a non-destroy detection technique, to investigate the relationship of lead leachability and pore structures in solidified concrete. Results show that total porosity has the greatest contribution to the leachability of lead in concrete; the second affecting factor is compressive strength, while the number of pore has a least contribution. In conclusion, radiation detection is a powerful technique to assess the anti-leaching ability of hazardous matters in recyclable solidified concretes of ashes.
