2022 Eshbach Lecture “Tailor-made soil properties by biogeochemical means”

October 12, 2022 @ 15:00 - 16:00

ABSTRACT: Among the non-conventional soil consolidation techniques, bio-mineralization has been a central focus of research for the past decade. At its core, Microbially Induced Calcium Carbonate Precipitation (MICP) is a multi-physical phenomenon, resulting in a natural CaCO3 bio-cement, capable of improving the mechanical properties of geomaterials. At the confluence of many disciplines, the technique is also proposed as a solution for a diverse range of geotechnical and geo-environmental applications. To better elucidate the fundamental mechanisms governing the process and thereby enabling better predictability and optimization, a holistic understanding of MICP is achieved through multiple levels of study, each with specific focuses and challenges, namely the microscopic, geotechnical laboratory and, field scale applications. A focus will be devoted to the multiphysical modelling of the chemo-bio-mechanical interactions at the constitutive as well as boundary problem levels.
