MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202444035663 A) filed by Karpagam College Of Engineering, Coimbatore, Tamil Nadu, on May 6, 2024, for 'lightweight reactive powder concrete.'
Inventor(s) include P. Jeganmurugan; G. Badma Sri; K. Jeeva Mathimaran; R. Karthickraja; and G. Karthigeyan.
The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "Reactive Powder Concrete (RPC) is known as a high strength, high durable concrete made by using fine powder materials, having a particle size less than 0.001mm (1). Lightweight reactive powder concrete contains Cement, Silica fume, Quartz sand, super plasticizer, fly ash and Quartz powder with low water cement ratio under special curing condition. Mix proportion of lightweight reactive powder concrete were identified by trial-and-error method, the size of concrete cube is 100mm X 100mm X 100mm were cast for finding compressive strength at 7, 14, and 28 days. By introducing aeration into RPC, the self-weight getting reduced and it is turned into lightweight reactive powder concrete."
