MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641024436 A) filed by Chennai Institute Of Technology, Chennai, Tamil Nadu, on March 2, for 'nano-bio activated fly ash cement for self-healing, climate-resilient indian infrastructure.'
Inventor(s) include P. Elaiyaraja.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a novel modular self-healing cement composite designed specifically for Indian climatic and infrastructural demands. The formulation integrates industrial fly ash as the primary binder, synergistically doped with nano-silica particles and biomineralizing bacterial spores such as Sporosarcina pasteurii, Bacillus subtilis, and Bacillus sphaericus. These microorganisms, in conjunction with nano-additives, actively induce microcrack sealing through calcium carbonate precipitation and silica bonding, enabling repeated cycles of autonomous repair. The composite further incorporates natural fibers (jute/coir) and hydration stabilizers to withstand India's extreme monsoon-summer heat cycles, ensuring superior durability, load-bearing capacity, and reduced water permeability. The invention also provides a sustainable circular economy model by valorizing 200+ million tons of Indian fly ash waste annually, reducing cement clinker dependency, and minimizing carbon emissions."
