MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122456 A) filed by Shruthi H G; and Atme College Of Engineering, Mysuru, Karnataka, on Dec. 5, 2025, for 'experimental investigation on partial replacement of cement with diatomaceous earth (de) and polypropylene fibers (ppf) in concrete.'
Inventor(s) include Shruthi H G; Atme College Engineering; Manish K M; Sunaina M R; and Mohammed Minhaz.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "Diatomaceous Earth (DE) is a certainly occurring, soft sedimentary rock composed of silica that easily disintegrates into a fine white or off-white powder. It consists of the fossilized remains of diatoms, a type of microscopic algae characterized by their silica-rich cell walls. Polypropylene fibers are synthetic fibers derived from polypropylene, a thermoplastic polymer. These fibers are regularly used across numerous industries due to their strength, resistance to chemicals, and cost-effectiveness. This study explores the potential of Diatomaceous Earth (DE) and Polypropylene Fibers (PPF) as alternatives to conventional reinforced concrete. The study investigates the partial replacement of certain materials for a fraction of the cement weight in concrete. Furthermore, it seeks to enhance the strength properties of concrete through this substitution, while also assessing the durability and environmental benefits provided by Diatomaceous Earth (DE) and Polypropylene Fibers (PPF)."
