Abstract
In this study, microbially induced carbonate precipitation (MICP) was implemented on specimens made of Edosaki sand whose fine content is around 20%, in order to seek possibilities of MICP in the soil containing fine. The result showed that precipitation of calcium carbonate was concentrated around the injection point possibly due to Edosaki sand’s low permeability which might have caused bacteria and reagents trapped around the region. Although the permeability of the specimens leveled out during the treatment, it dropped significantly after the termination of the treatment which was followed by circulation of distilled water. Precipitation efficiency varied approximately from 40% to 60%. Further research needs to be performed to enable uniformly distributed and efficient MICP in the soil with fine.(120 words)
