The process of ureolysis-driven biocementation is used to improve granular soils. The precipitation of calcium carbonate (CaCO3) crystals results from the reactions of urease generated by ureolytic bacteria and chemical reagents, which strengthen or

Biocalcification is a recent in-situ soil consolidation solution. It is obtained by calcite precipitation under controlled biogeochemical conditions. The industrial process, for whose implementation Soletanche Bachy holds several patents, has been va

International audience; Microbial-induced carbonate precipitation (MICP) in porous media is a two-step procedure: First, the suspension of bacteria is injected and some of the bacteria get stuck on the grains. The second stage consists in the injecti

Performance Studies of Microbial Induced Calcite Precipitation to Prevent the Erosion of Internally Unstable Granular Soils
Autor: Benoît Courcelles, Annette Esnault-Filet, Fatima-Zahra Haouzi
Publikováno v: Advancements on Sustainable Civil Infrastructures ISBN: 9783319962405
Migration of fine particles within internally unstable granular soils under water seepage flow (suffusion) is one of the most common causes of earth infrastructures’ failure. To assess the ability of Microbial Induced Calcite Precipitation (MICP) t

Amélioration des propriétés mécaniques des sols par biocimentation : étude mécanique et microstructurale
Autor: Aurélie Garandet, Christian Geindreau, Abdelali Dadda, Fabrice Emeriault, Annette Esnault-Filet
Publikováno v: Revue Française de Géotechnique. :4
Le procédé de bio-cimentation est une technique prometteuse pour renforcer les sols lâches et de faible résistance mécanique. Cette technique a montré une très bonne efficacité pour plusieurs types de sols lors d’essais en laboratoire, dans
