MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621039368 A) filed by Indian Institute Of Technology, Maharashtra, on March 30, for 'thermochemical activation-based three-dimensional printable alkali-activated concrete (aac) composition and method of manufacturing thereof.'
Inventor(s) include Suthar Mahendrabhai Bharatbhai; Mohammad Najeeb Shariff; and Prakash Nanthagopalan.
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 disclosure relates to an economical and sustainable composition for thermochemical activation-based Three-Dimensional (3D)-printable alkali-activated concrete (AAC) and a method of manufacturing thereof. The composition comprises a thermochemically activated binder system, at least one aggregate and a rheology modifier. The thermochemically activated binder system comprises a first aluminosilicate precursor mixed with a solvent, activated by an alkaline activating agent to form a primary activated binder mixture and a second aluminosilicate precursor subsequently activated by the primary activated binder mixture. The primary activated binder mixture is formed by activation of the first aluminosilicate precursor by exothermic heat generated upon dissolution of the alkaline activating agent in the solvent without the need for external energy or sodium silicate solution. The composition exhibits extrudability, rheological stability, and buildability suitable for 3D printing, enabling an energy-efficient and simplified manufacturing process."
