Title (EN) HYDROGEL BIOCEMENT SYSTEMS AND METHOD
(FR) SYSTÈMES ET PROCÉDÉ DE BIOCIMENT À BASE D’HYDROGEL
Abstract:
(EN) A soil stabilization method of forming an admixture of at least one hydrogel precursor and urease enzyme, and contacting at least a portion of the admixture with soil, and forming a hydrogel network in-situ within at least a portion of the soil, wherein at least a portion of the hydrogel network includes in-situ precipitated calcium carbonate. In some embodiments, at least a portion of the hydrogel network is formed in-situ by polymerizing the at least one hydrogel precursor in the presence of the urease enzyme.
(FR) La présente invention concerne un procédé de stabilisation de sol destiné à la formation d’un mélange par admixtion d’au moins un précurseur d’hydrogel et d'une enzyme uréase, la mise en contact d’au moins une partie du mélange par admixtion avec le sol, et la formation in situ d’un réseau d’hydrogel à l’intérieur d’au moins une partie du sol, au moins une partie du réseau d’hydrogel comprenant du carbonate de calcium précipité in situ. Dans certains modes de réalisation, au moins une partie du réseau d’hydrogel est formée in situ par polymérisation dudit précurseur d’hydrogel en présence de l’enzyme uréase.
