MUMBAI, India, Oct. 31 -- Intellectual Property India has published a patent application (202441033036 A) filed by K. Ramakrishnan College Of Technology, Trichy, Tamil Nadu, on April 26, 2024, for 'coir-pith concrete panel.'
Inventor(s) include Mr. A. Oorkalan; Dr. S. Chithra; Mr. S. Arun; Mr. R. Jayakarnan; Mr. P. Kirubanithi; and Mr. R. Abu Bakkar Siddique.
The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses a coir pith concrete panel for utilization of coir pith in concrete panel manufacturing offers a sustainable alternative to traditional materials. Coir pith, derived from coconut husks, enhances concrete properties with its longer decomposition time and exceptional water-holding and retaining capacities, attributed to its composition of hemicelluloses, cellulose, and lignin. Coir pith fibers, containing numerous air voids, contribute to thermal insulation within structures. The manufacturing process involves soaking coconut shells, combing and drying fibers, and sieving to remove impurities. OPC Grade 53 cement serves as the binding agent, while angular fine aggregate (sand) and 20mm coarse aggregate improve concrete strength and bulk capacity. A concrete mix, comprising specified proportions of these materials, undergoes conventional mixing and curing methods to achieve desired strength properties."
