MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122111 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Dec. 4, 2025, for 'method for producing pervious concrete using thermo-mechanically treated recycled coarse aggregate and ground granulated blast furnace slag.'
Inventor(s) include Dr. Viswanathan T S; Bonta Sanjay; Shaik Nishar Ali; and Abdul Majeed.
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 present disclosure provides a method (100) of producing pervious concrete including collecting construction and demolition waste in a step (102) and separating coarse aggregate therefrom in a step (104), subjecting the recycled coarse aggregate to thermal treatment in a step (114) to weaken bonds between aggregate particles and adhered mortar, subjecting the thermally treated recycled coarse aggregate to mechanical abrasion in a step (116) to remove the adhered mortar, sieving the treated recycled coarse aggregate in a step (118), preparing a pervious concrete mix in a step (122) including the treated recycled coarse aggregate and ground granulated blast furnace slag as partial replacements, and casting pervious concrete specimens in a step (126) and curing for 28 days in a step (128), wherein the resulting pervious concrete achieves compressive strength exceeding 25 MPa while maintaining void ratio above 20%."
