MUMBAI, India, Dec. 13 -- Intellectual Property India has published a patent application (202511103353 A) filed by Indian Institute Of Technology, Ropar, Punjab, on Oct. 27, for 'portable digital concrete slump test apparatus with wireless data logging.'
Inventor(s) include Dr. Ashish Shukla; and Dr. Aditya Singh Rajput.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to a portable digital concrete slump test apparatus configured for automated measurement of the workability of fresh concrete. The apparatus integrates a digital linear displacement sensor with a standard slump cone assembly conforming to IS 1199:2018 or ASTM C143 standards. A microcontroller-based processing unit receives the sensor signal, performs analog-to-digital conversion, and computes calibrated slump values. The processed data is transmitted wirelessly via Bluetooth or Wi-Fi communication module to a mobile computing interface that displays, logs, and stores the slump measurement along with associated metadata including date, time, GPS location, and operator identification. The embedded firmware automates calibration, data validation, and real-time transmission, eliminating manual observation errors. The system is battery-powered and field-deployable, designed for accurate, repeatable, and traceable digital slump measurement using standardized test geometry."
