MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202621106261 A) filed by National Institute Of Technology Goa on September 03, 2026, for Ultrafine Slag-Based Geopolymer Mortar Composition And Process For Preparation Thereof Using A Single Sodium Hydroxide Activator.
Inventors include Dr. Sathishraj Mani; and Dr. Harikumar Mohanan.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention relates to an ultrafine slag-based geopolymer mortar composition and a process for preparation thereof using sodium hydroxide as a single alkaline activator. The composition comprises ultrafine ground granulated blast furnace slag, fine aggregate, and a 9 M sodium hydroxide solution, while sodium silicate is excluded from the activation system. In disclosed embodiments, the sodium hydroxide solution is used at 440 kg/m³ with binder contents of 733.30, 745.80, or 758.60 kg/m³, without extra water or superplasticizer. Chloride-admixed and composite chloride-sulfate-admixed embodiments are prepared using controlled salt dosages relative to total geopolymer solids. The chloride-admixed mortar exhibits enhanced compressive strength, while composite chloride-sulfate formulations substantially retain strength under ambient curing. The invention provides a simplified and sustainable single-activator mortar suitable for construction applications involving aggressive ionic conditions.
