MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641062177 A) filed by Mr. K. Srinivasan; Dr. A. Muthadhi; and Dr. A. Kalaisselvane, Pondicherry, India, on May 15, for 'self-curing concrete composition using processed sargassum powder as internal curing agent.'
Inventor(s) include Mr. K. Srinivasan; Dr. A. Muthadhi; and Dr. A. Kalaisselvane.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a self-curing concrete composition utilizing processed sargassum powder as a natural internal curing agent. The composition comprises cementitious material, fine aggregate, coarse aggregate, mixing water, and processed sargassum powder configured to absorb and gradually release moisture during hydration of cementitious material. The processed sargassum powder is prepared through washing, drying, and grinding of marine sargassum material for reducing impurities and salt content prior to incorporation into a concrete matrix. The gradual release of retained moisture maintains internal curing conditions, reduces self-desiccation, minimizes autogenous shrinkage and cracking, and improves hydration efficiency within the concrete composition. The invention further improves compressive strength, durability characteristics, permeability resistance, and resistance against water absorption and chemical attack under ambient curing conditions. The self-curing concrete composition provides a sustainable and bio-based alternative to synthetic internal curing agents while reducing dependency on external water curing practices."
