초록
The aim of this study is to investigate strength and water purification characteristics of effective microorganism-applied volcanicash block using flexural strength test and water quality analysis. The specimens were prepared with volcanic ash from Mt. Baekdusanand Mt. Hallasan, and cement as the ratios of 3.5:1, 4.0:1, 4.5:1, 5.0:1 with and without metakaolin. Flexural strength degraded withincreasing of the amount of volcanic ash, and increased with addition of metakaolin as a binder. Based on these results, the optimalratio for fabricating volcanic ash-cement mixture block is determined as 3.5:1 with metakaolin. Furthermore, from water qualityanalysis on contaminated water, removal ability of effective microorganism-applied volcanic ash-cement mixture block and cagedvolcanic ash block against T-N, T-P and SS was highly evaluated because of adsorption due to the large specific surface area ofvolcanic ash. Hence, volcanic ash-cement mixture block and caged volcanic ash block possibly contribute to water purification.
