Inventor(s) include Dr. Mini Mathew; and Aswin Krishna M. A.
The application for the patent was published on June 27, under issue no. 26/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to cold bonded lightweight artificial aggregates from red mud and quarry waste. Red mud, quarry dust and Ordinary Portland cement, is dry mixed together to get the composition for preparing the lightweight artificial aggregates. The red mud is taken in a range of 40-60% w/w. Quarry dust is taken in a range of 30-40% w/w, and OPC is taken in a range of 10-20% w/w. To form the aggregates, water is added to the mixture in the range of 25-30 w/v. The artificial aggregates are developed inside the mixing chamber/concrete mixer. The mixer drum rotates at a speed of about 20 rpm. Due to rotating movement or tumbling force during mixing, the pellets or aggregates are developed. The pellets are air cured for about 28 days at room temperature while covering with a wet sack."
