MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641042253 A) filed by Chennai Institute Of Technology, Chennai, Tamil Nadu, on April 2, for 'development of eco-friendly geopolymer concrete using toor dal (cajanus cajan) husk ash.'
Inventor(s) include Dr. P. Partheeban; Dr. Sangeeta Dayal; Mr. M. Chandru; Dr. A. Kavitha; Dr. B. Anuradha; and Dr. P. Vasanthi.
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 increasing global focus on the sustainable management of agricultural residues has created a dire need for the utilization of wastes produced during harvesting, which are otherwise indiscriminately disposed of and are a source of environmental pollution. There is a great opportunity for such waste to be utilized by the concrete industry in an effort to decrease the natural resource depletions while also contributing to sustainable development and circular economy principles. Previous research indicated the ability of various agricultural residues, like toor dal (Cajanus cajan) husk ash (TDA) or pigeon pea stalk ash (PPSA), to replace up to 20% of cement, enhancing the properties of concrete, while decreasing the carbon footprint associated with conventional cement production. This study aims to investigate the feasibility of utilizing toor dal husk ash (TDA) instead of Class-F fly ash in a geopolymer concrete mixture with the objective of enhancing the strength properties in an eco-friendly way."
