VOLCANIC ASH, CEMENT AND METAKAOLIN MIXED SOILS AND AN USE THEREOF

摘要

The present invention relates to a mixed soil which mixes volcanic ash, cement and metakaolin in proper capacities to increase the strength and to a use of the same. The mixed soil according to the present invention has properties of increasing compression strength and bending strength to be applied to such as bio-vegetation blocks and artificial fishing banks for water purification. Moreover, if effective microorganism is additionally mixed with the mixed soil, the water purification effect can be more improved.
