Outline of Final Research Achievements

In this study, Authors proposed that the self deterioration mitigation functional cement treated soil was proposed based on the microbial functions. The advantage points of proposed methods are i) Urease producing bacterium from shallow and deep-sea sediments can support the deterioration mitigation techniques based on the In-situ calcite precipitation, ii) can applying the conventional construction machine such as deep mixing and jet grouting, iii)Proposed method can apply the sand and silt which can maintain the almost 20% reduction effect of deteriolation depth
