MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202444037621 A) filed by Karpagam College Of Engineering, Coimbatore, Tamil Nadu, on May 13, 2024, for 'fly ash foundry sand concrete.'
Inventor(s) include Sneha N; Arunmurugan P; Karthikeyan B; Mohamed Jaman M; and Rakesh Roshan S K.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "Waste and find the solution of resulting it the most serious problem of the world today. Waste utilization has become an attractive alternative to disposal nowadays. Recycling waste items to produce construction material like concrete appears as one of the best solutions for the disposal of waste materials. Concrete is the most widely used construction material all over the globe next to water. The present challenge for civil engineers is to produce large volumes, good performance, durable and sustainable concrete at the lowest possible cost. This experimental work is carried to study the mechanical & durability characteristics of the concrete blocks, made with cement is partially substituted with fly ash 30%, Foundry sand, and waste concrete. compressive strength test has been carried out to find out the mechanical characteristics of the concrete at 7?days, 14 days, and 28?days. In this concrete mix, we utilize a replacement of cement with fly ash and admixtures NaOH & NaSiO3, replace fine aggregate with foundry sand at a 40% substitution rate, and substitute coarse aggregate with concrete debris also at 100%. The experiment was done with M30 grade concrete for curing of 7 days,14 days, and 28 days from which its compressive strength, flexural strength, split tensile strength, shear strength, and modulus of elasticity were taken and compared with the conventional concrete."
