MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202631070515 A) filed by Kalinga Institute Of Industrial Technology Kiit Deemed To Be University on June 05, 2026, for High-Performance Concrete Composition With Fly Ash Cement Replacement.
Inventors include Mohanty, Tribikram; Saha, Srishti; Acharya, Prasanna Kumar; and Yadav, Surendra.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: A high-performance concrete composition includes a binder having Ordinary Portland Cement and fly ash, wherein the fly ash constitutes 30% to 40% of the binder by weight, a fine aggregate, a coarse aggregate, a superplasticizer at 0.5% by weight of the Ordinary Portland Cement, and water at a water-cement ratio of 0.35. The composition has a mix proportion of 1:0.83:2.68 for binder to fine aggregate to coarse aggregate by weight. The fly ash may comprise Class F fly ash. The binder content may be 480 kg per cubic meter of concrete. The composition achieves a compressive strength of at least 60 MPa at 28 days. The composition exhibits reduced permeability and reduced bleeding compared to a concrete composition without fly ash, and exhibits resistance to chlorides, sulphates, and acid attack. (Figure 1)
