Characteristics Evolution of Transylvanian Sand after Biogrout Treatment
This paper presents the evolution of Transylvanian sand characteristics after calcium based Biogrout treatment. By injection into the sand body of microbiological entities and certain chemicals sand is transformed into sand-stone in a short time by a phenomena called Microbially Induced Carbonate Precipitation – MICP. Triaxial testing was performed on treated samples in a confined-drained system and geotechnical and mechanical parameters were calculated. The results obtained were then compared with data from triaxial tests on the same untreated sand in the same conditions. It has been found that sand parameters suffer significant changes after Biogrout treatments in only a short period of time.
