MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631061066 A) filed by National Institute Of Technology, Durgapur, West Bengal, on May 13, for 'a systematic mixing procedure for enhanced strength development in geopolymer concrete.'
Inventor(s) include Suman Saha; and Sharwar Ahmed Chowdhury.
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 discloses a systematic mixing process for preparing geopolymer concrete with enhanced compressive strength under ambient curing conditions. The process comprises pre-mixing Class F fly ash and ground granulated blast furnace slag (GGBS) to form a homogeneous binder, preparing an alkaline activating solution comprising sodium hydroxide and sodium silicate solutions with a stabilization period, and forming a dry aggregate-binder mixture through sequential addition of aggregates and binder. The alkaline activating solution is incorporated in a staged manner by first adding sodium hydroxide solution followed by sodium silicate solution with controlled mixing durations. The resulting mixture is cast, compacted, and cured at ambient temperature without heat curing. The process yields geopolymer concrete exhibiting compressive strength in the range of 60-70 MPa at 28 days and 40-50 MPa at 7 days. The invention provides a reproducible and scalable methodology suitable for field applications while reducing dependence on trial-and-error mix design practices."
