MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202541121536 A) filed by Mahindra University, Hyderabad, Telangana, on Dec. 4, 2025, for 'scalable silica fume-modified cementitious coating for steel fibers in fiber-reinforced concrete (frc).'
Inventor(s) include Dr. Mohd Ataullah Khan; and Mr. Venugopal Mandala.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "A high-performance, silica fume-enhanced cementitious coating and method for treating steel fibers used in fiber-reinforced concrete (FRC) is disclosed. The coating comprises a silica fume-modified cementitious blend optimized for particle packing, pozzolanic reactivity, and interfacial densification. The coating is applied by immersion, spraying, or drum-coating, followed by controlled pre-curing. The coated fibers exhibit significantly improved fiber-matrix interfacial bonding, doubling pull-out strength and tripling pull-out energy. Concrete reinforced with such fibers demonstrates approximately 90% improvement in flexural strength and 110% improvement in toughness. The coating provides superior corrosion resistance, enhanced microstructural densification, and improved durability. The method is environmentally friendly, cost-effective, and scalable for industrial implementation."
