MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202521125042 A) filed by Parul Institute Of Engineering And Technology; Ms. Parul Mangal; and Dr. Jayesh Juremalani, Vadodara, Gujarat, on Dec. 11, 2025, for 'development of self-curing concrete by using hydrogel and calotropis gigantea latex as self-curing agents in m45 grade concrete.'
Inventor(s) include Ms. Parul Mangal; and Dr. Jayesh Juremalani.
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: "This project introduces an innovative self-curing concrete by incorporating 0.2% Hydrogel (Superabsorbent Polymer) and 0.3% Calotropis gigantea latex as internal curing agents. The combined system is designed to address the drawbacks of conventional external curing, especially in regions with limited water availability or where curing operations are difficult to execute. The Hydrogel acts as an internal moisture reservoir, absorbing water during mixing and gradually releasing it throughout the hydration process. Simultaneously, the Calotropis latex reduces evaporation and improves water retention within the concrete matrix. Together, these components enhance the hydration process, reduce autogenous shrinkage, and increase compressive strength. This approach promotes sustainability by reducing dependence on external curing water and minimizing labor requirements. The project has been successfully developed and experimentally validated, demonstrating superior performance compared to traditional M45 grade concrete cured using standard methods."
