MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631026903 A) filed by Dr. Sudhir Chandra Sur Institute Of Technology And Sports Complex, Kolkata, West Bengal, on March 7, for '"bacterial concrete system for corrosion-protection of steel reinforcement in rcc structures".'
Inventor(s) include Debargha Banerjee; Krishnendu Kundu; Souradeep Roy; Debargha Banerjee; and Dr. Saradindu Panda.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A bacterial concrete system protects steel reinforcement in concrete structures from corrosion on its own. The system has separate, breakable capsules that hold dormant bacterial spores and separate nutrient reservoirs. Both of these are strategically placed in the concrete matrix around the reinforcement. When cracks form and water get in, the capsules break open, letting bacteria out that eat nutrients from the reservoirs. This causes bio-mineralization, which creates a thick, sticky layer of calcium carbonate directly on the steel surface to protect it. At the same time, it causes minerals to fall out of the crack to seal it. The system focuses on protecting the steel-concrete interface, which makes the service life longer with little outside help."
