Title:
CROSS SECTION REPAIR MATERIAL BASED ON HALOPHILIC SLIME-FORMING BACTERIA
Document Type and Number:
WIPO Patent Application WO/2022/102882
Kind Code:
A1
Abstract:
Disclosed is a novel ecological salt damage-resistant repair material for repairing concrete structures that have been exposed to an environment of chemical degradation due to salt damage (Cl-) in a marine environment, wherein the repair material excludes existing organic materials. The present invention provides a material for repairing a concrete cross section in a salt damage environment, the concrete cross section repair material comprising a mixture of a salt damage resistant repair material and a carrier, wherein the salt damage resistant repair material comprises a binder, including ordinary type 1 Portland cement and an EVA-based polymer, polyethylene fibers, and fine aggregate, and the carrier has a porous structure on which bacteria for breaking down chlorine ions and halophilic slime-forming bacteria are fixed.
