Hello! We are Abstract Concrete from the Senior Project II (EE 4220) class at the University of Texas at El Paso. Please allow us to introduce ourselves:
Dr. Nazarian presented the problem of having to test concrete maturity by making manual measurements with a similar project that was created in a previous senior project class. In order to attain accurate results, the test must be made at regular intervals over a full day. It is extremely difficult for a person to be alert for that long of a period. With our group building an automated tester, a civil engineer can simply leave the machine attached to the concrete and come back after a day to check on the results. The machine increases the accuracy of the tests and also will not tire out like a person does. The machine will be powered and run by a Lab View program running on a PC. Using a special card from National Instruments, an attached accelerometer will take natural frequency readings of the concrete once the concrete is impacted by a solenoid. Also, a thermocouple will provide temperature readings to Lab View, which will then compile all the data into a Microsoft Excel spreadsheet. When completed, civil engineers will have accurate concrete analyses with very little hassle. The user interface from the previous project will also be updated to allow for a user who has minimal computer skills. Dr. Nazarian will be providing the funding for the project, which will cost approximately $1,500 to complete.
