영문 초록

In this study, we carried out the research for the recycling potential of the dyeing wastewater treatment sludges as construction materials. The incineration ash of sludges were solidified as interlocking block in condition of sludge/cement ratio 2.5%, 5.0% and 10%, respectively. Those interlocking blocks were cured for 3days, 7days and 28days in ambient air condition, respectively. The results of this research were summarized as follows: The dyeing wastewater treatment sludges was below the Korea Leaching Limit. After incineration, the ash was manufactured as interlocking block. Bendable strength over 50 kgf/cm2 suitable for interlocking block was obtained only when the sample was cured for 7days at sludge/cement ratio 2.5% and 5.0%. Hygroscopic ratio of interlocking block was above the Korea Industry Standard. We think that recycling of the incineration ash from dyeing wastewater treatment sludges to interlocking block will have high potential possibility.
