Claims14
A biocementation method comprising:
- (A) forming a mixture comprising:
- (i) at least one organism which is capable of forming carbonate, or of inducing and/or catalysing carbonate formation, and/or at least one enzyme which is capable of forming carbonate or of inducing and/or catalysing carbonate formation,
- (ii) at least one substance for forming carbonate,
- (iii) at least one water-soluble, water-dispersible and/or water-emulsifiable, cohesion-modifying compound comprising at least one calcium-binding functional group or at least one carbonate-binding functional group
- wherein the cohesion-modifying compound having the at least one calcium-binding functional group or carbonate-binding functional group is calcium lignosulfonate, sodium lignosulfonate, potassium lignosulfonate, magnesium lignosulfonate, ammonium lignosulfonate, and combinations thereof, and
- (B) applying the mixture to/into a substrate to be treated, thereby enabling biocementation.
