MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611025708 A) filed by NIT, Jalandhar, Punjab, on March 5, for 'a device and method to compute dynamic viscosity and yield stress of self-compacting concrete.'
Inventor(s) include Tejinderpal Singh; Dr Kanish Kapoor; and Dr Surinder Pal Singh.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention is a device and method for calculating the yield shear stress and dynamic viscosity of self-compacting concrete based on fundamental physics and fluid mechanics concepts. The device uses a cylindrical chamber that is positioned vertically and has an automatic lid-triggered timer to monitor the discharge duration. This allows for the direct calculation of dynamic viscosity and mean flow velocity. In order to determine yield shear stress, the released concrete is gathered in a secondary chamber and equilibrium heights are noted at two points. In contrast to traditional rheometers, the invention does away with costly apparatus and empirical regression. The device is appropriate for both labs and construction sites since it offers quick, repeatable, and field-deployable readings. In addition to providing accurate rheological parameters necessary for quality control and self-compacting concrete performance optimization, the invention drastically cuts down on testing time, labor, and expense."
