MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641040628 A) filed by National Institute Of Technology, Mangaluru, Karnataka, on March 31, for 'a high-strength pre-casted construction material, building blocks and binder composition thereof.'
Inventor(s) include T Palanisamy; and Niveditha M.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to producing precast construction materials/ precast building blocks with a cement-free binder composition, utilizing iron-rich industrial waste and supplementary mineral additives. The binder composition is activated using saline water in the presence of a chelating agent and subsequently subjected to curing in a carbon dioxide-enriched environment to form a hardened binder matrix through mineral transformation reactions. The process comprises proportioning industrial waste-based binder materials, homogeneous mixing, controlled addition of saline water and chelating agent, casting into moulds, and carbon dioxide curing under regulated conditions. The resulting precast construction elements exhibit enhanced densification, structural performance, and carbon mineralization without the use of conventional cement or freshwater curing methods. The invention provides a sustainable alternative for construction applications utilizing industrial waste and saline water resources."
