MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122465 A) filed by Bharathi B; and Atme College Of Engineering, Mysuru, Karnataka, on Dec. 5, 2025, for 'method and system for utilizing processed steel slag for sustainable and eco-friendly rigid pavement concrete.'
Inventor(s) include Bharathi B.
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: "The invention relates to a method and system for producing sustainable and eco-friendly rigid pavement concrete using processed waste steel slag as a partial replacement for natural coarse aggregates. Steel slag, an industrial by-product, is processed through crushing, aging, and grading and used at optimal replacement levels of 30% to 60% in concrete mixes of grades M20 to M50. Experimental analysis demonstrates that the inclusion of steel slag results in enhanced compressive strength (5-10%), improved split tensile strength (4-8%), and increased flexural strength (2-6%). The invention provides a systematic approach involving mix proportioning, workability assessment, mechanical testing, and pavement layer application. The resulting concrete offers superior durability, reduced permeability, and improved resistance to environmental degradation, while significantly reducing dependence on natural aggregates and promoting sustainable construction practices. Key words: Steel slag; sustainable concrete; rigid pavement; mechanical strength; durability; eco-friendly construction; recycled materials."
