TI  - Effects of Ground Conditions on Microbial Cementation in Soils.

AB  - The purpose of this study is to understand the effect of ground conditions on 
      microbial cementation in cohesionless soils. Since the method of microbial 
      cementation is still at the experimental stage, for its practical use in the 
      field, a number of laboratory experiments are required for the quantification of 
      microbial cementation under various ground conditions, such as relative 
      densities, relative compactions and particle size distributions. In this study, 
      in order to evaluate the effectiveness of microbial cementation in treated sands 
      and silts, an experiment was performed for different relative densities of silica 
      sands, for different relative compactions of silts and for different particle 
      size distributions of weathered soils sampled from the field. Scanning electron 
      microscope (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) 
      spectroscopy and mapping analyses were implemented for the quantification of the 
      levels of microbial cementations for sand, silt and weathered soil specimens. 
      Based on the test results, a considerable microbial cementation was estimated 
      depending on the soil conditions; therefore, an implementation of this new type 
      of bio-grouting on a weak foundation may be possible to increase the strength and 
      stiffness of weak ground.
