Biocementation as a Pro-Ecological Method of Stabilizing Construction Subsoil

The principle of sustainable development imposes an obligation on societies to manage natural resources rationally and care for the quality environment, by, among other things, reducing CO2 emissions. Alternative ways stabilising building substrates by increasing their shear strength (cu) are increasingly being sought. This paper presents how microorganisms can influence cu thus load-bearing capacity substrates. Tests were performed in a triaxial compression apparatus three variants. first variant testing was carried out cemented soil samples, which situ. next two series tests reconstructed i.e., inoculated with solution Sporosarcina pasteurii bacteria. results obtained show that carbonate cementation increases soil; addition, this biomineralization-induced gives higher than cementation.
