MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641042244 A) filed by Chennai Institute Of Technology, Chennai, Tamil Nadu, on April 2, for 'an integrated system and method for converting agricultural residue biomass into a geopolymer concrete precursor.'
Inventor(s) include Dr. Partheeban P; Dr. Sangeeta Dayal; Mr. M. Chandru; Dr. A. Kavitha; Dr. B. Anuradha; and Dr. P. Vasanthi.
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: "The present invention relates to a geopolymer-based concrete composition utilizing agricultural biomass-derived aluminosilicate ash, particularly toor dal husk ash, as a sustainable binder component for the manufacture of high-performance concrete materials. The composition comprises thermally processed biomass ash, supplementary aluminosilicate precursor materials such as Class-F fly ash, an alkaline activator solution including alkali hydroxides and alkali silicates, a polymer-based binding agent such as carboxymethyl cellulose, fine aggregates, coarse aggregates, and water. The method of manufacture involves controlled thermal conversion of biomass to produce reactive ash, pulverization and characterization of the ash, preparation of the alkaline activator solution, homogeneous mixing of dry constituents followed by addition of activator and polymer binder, casting of the mixture into molds, and curing under ambient or solar-assisted conditions to form a dense geopolymer matrix."
