MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202641082425 A) filed by Vallurupalli Nageswara Rao Vignana Jyothi Institute Of Engineering Technology on July 03, 2026, for A Process For Manufacturing Artificial Fly Ash Coarse Aggregates (afca).
Inventors include Dr. Pupalwad Arti Sudam; Dr. Kadali Srinivas; and G Vaishnavi.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The present invention introduces a novel process for producing Artificial Fly Ash Coarse Aggregates (AFCA) as a sustainable substitute for natural coarse aggregates in concrete applications. By utilizing industrial fly ash through optimized geopolymerization and granulation techniques, the method transforms a problematic waste material into high-performance construction aggregates with enhanced mechanical properties. The process involves careful selection of Class-F fly ash, optimization of alkaline activators, controlled mixing, granulation, and curing to create durable, well-bonded particles. Comprehensive characterization through physical, chemical, engineering, mineralogical, and thermal analyses confirms the quality of AFCA, while concrete performance testing demonstrates comparable compressive strength to conventional mixes. This innovation provides an environmentally responsible solution that reduces reliance on natural resources, valorizes industrial by-products, and supports scalable sustainable construction practices with consistent and reproducible results.
