Abstract

The final outcome of this project is to examine the mechanical and resulting physical properties of bio-treated soil through microbial activity via non-destructive testing by seismic waves. The proposed bio-treatment strategy is through supplying specific nutrients for indigenous microbes within a soil specimen which in return produce calcium carbonates. The bio-minerals produced during these biogeochemical activities will improve the mechanical properties of soil by making cementation between soil grains. Additionally, a theoretical laboratory experimentational description will be provided to explain any associative effects on a specimen's water permeability or mechanical strength due to bio-mineralization within the samples. The characterization of mechanical and hydraulic behavior of bio-treated soils are critical to examine the effectiveness of the treatment cycles. Therefore, in this project we aim to employ the concept of seismic wave propagation to measure properties of bio-treated soils in a non-destructive manner.
