MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541126669 A) filed by Mepco Schlenk Engineering College; Dr. S. Surlya; Dr. M. Chellapandian; and N. Radhakrishnan, Sivakasi, Tamil Nadu, on Dec. 15, 2025, for 'proposing effective surface treatment techniques for light weight expanded clay aggregate.'

Inventor(s) include S. Surlya; M. Chellapandian; and N. Radhakrishnan.

The application for the patent was published on Feb. 13, under issue no. 07/2026.

According to the abstract released by the Intellectual Property India: "In the present scenario, repl"acing a portion of coarse aggregate with ceramic tile waste in paver block manufacturing advances importance due to environmental considerations and the possibility of cost reduction. It helps in lowering landfill waste, conserving natural resources, and enhancing specific characteristics of the paver blocks. In India, the generation of ceramic tile waste is estimated to be between 15-30% of total production. The use of ceramic materials in building is steadily rising, particularly in the forms of tiles, sanitary fixtures, and electrical insulations. A significant amount of ceramic waste material becomes useless during production, shipping, and fixing due to its brittle properties. This study aims to :;;ubstitute coarse aggregate with ceramic tile waste in paver blocks and to decrease the cost of paver blocks compared to conventional concrete paver blocks. The target compressive strength fixed for the proposed paver block was 25 N/mm2* During the casting process, the coarse aggregate was substituted with ceramic tile waste at different proportions of 0% (conventional), I 0%, 20%, and 30%, respectively. After the paver blocks were cast, they undergo a curing process of up to 28 days . Then, the compression strength test and water absorption test were conducted. From the obtained results, the percentage replacement of tile waste increases, and the strength decreases. The replacement" level of waste ceramic tiles up to 10% in concrete mix does not retard the properties when compared to other replacement levels."
