MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051307 A) filed by Mrs. A. Bhagyalaxmi; Mr. S. Pranay; Mr. K. Deepak; Mr. B. Santosh; Ms. K. Sahithi; and Mrs. K. Deepa, Hyderabad, Telangana, on April 22, for 'a sustainable self-compacting concrete composition using recycled tile aggregate and fly ash with enhanced mechanical and workability properties.'
Inventor(s) include Mrs. A. Bhagyalaxmi; Mr. S. Pranay; Mr. K. Deepak; Mr. B. Santosh; Ms. K. Sahithi; and Mrs. K. Deepa.
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 invention relates to a sustainable self-compacting concrete (SCC) composition incorporating recycled ceramic tile aggregate as a partial replacement for natural coarse aggregate and fly ash as a partial replacement for cement. The developed concrete is capable of flowing under its own weight without the need for mechanical vibration, thereby ensuring complete compaction, improved surface finish, and reduced labor requirements. The recycled tile aggregate is processed by crushing and grading waste ceramic tiles into suitable sizes for use in concrete. The invention evaluates different replacement levels of coarse aggregate with tile aggregate, ranging from 0% to 20%, to determine the optimal proportion for achieving enhanced performance. The results indicate that an optimum replacement level of approximately 15% provides improved compressive and tensile strength compared to conventional self-compacting concrete, along with excellent workability characteristics such as high slump flow and adequate passing ability. The inclusion of fly ash further enhances the workability, durability, and long-term strength of the concrete while reducing cement consumption and environmental impact. The invention provides an eco-friendly, cost-effective, and high-performance concrete solution suitable for modern construction applications, particularly in structures with congested reinforcement and complex formwork."
