碩士 === 國立中央大學 === 土木工程學系 === 101 === Corresponding with referenced price in the Public Construction Commission in order to conduct economic feasibility test, this studies focuses on the analysis of basic properties of incinerator bottom ash. We firstly conducted dynamic leaching test to assess the environmental impact, and this is followed by permeable concrete analysis of bottom ash, exploring its uniformity and stability. The results revealed that the permeable concrete made with incinerator bottom ash demonstrated compressive strength of 2.3 ~ 4.67Mpa, meeting the standard specified in the “Chapter Outline Section 02794 Permeable Concrete”. Furthermore, there were little or no heavy metals found in the dynamic leaching test. The studies also manifested, by the process of washing and screening, incinerator bottom ash showed a vast amount of homogeneity and stability after properly reprocessed. In terms of higher wear rate of incinerator bottom ash, it is suggested to adopt blending methodology for the purpose of reuse. According to the current market price, the cost of processing incinerator bottom ash into permeable concrete is NTD 633.5 ~ 763.6, compared to non-processed aggregate with a price approximately NTD 1,247.1. These analyses indicated incinerator bottom ash is a safe and cost-effective material in engineer applications. Finally, this studies aims to provide constructive recommendation to “Chapter Outline Section 03341”, assisting incinerator bottom ash in having a more extensive adoption in practice.
