Impact Echo System for Field Evaluation of Concrete Structures

James Instruments, Inc. Vu-Con System

Impact Echo System for Measuring the Thickness and Quality of Concrete

The Vu-Con™ Analyzer provides the engineer with the sturdiest most reliable system for impact echo analysis. No moving parts and implementation of the latest microcomputer technology has created a system that is both sophisticated and reliable. The unit comes with a 90 mm (3.5) by 115 mm (4.5ï¿1/2) graphic display screen that is easily viewed in daylight. This allows rapid analysis of results in situ. It may store more than 200 individual tests with time and date indication.

The data is easily uploaded to a PC for inclusion in reports and data analysis. Data communication takes place via the RS-232 port and Windows compatible PC software. The unit allows the user to select sensitivity levels to adapt to varying conditions in the field.

The built in menu system has provisions for determining all the parameters for the material under test. The thickness menu allows rapid display of the frequency spectra of an impact. Peaks are automatically found and highlighted for a given test. The velocity menu, for use with the dual transducer set, facilitates determination of the stress wave speed in a given material. This allows the operator to gather and analyze data quickly and easily in the field. Finally, the user can select from multiple gain settings for various material dimensions. There is also a selection of multiple data sampling rates and an adjustment for different trigger levels, which help the user produce accurate and reliable results.

Results:

The resulting amplitude waveform from the transducer can be displayed for analysis both with respect to time and frequency. This is illustrated by graphs. The time domain waveform can be described as a sum of a series of different frequency waveforms.

This allows the user to:

  • Analyze the dominant frequencies of vibration found from the impact and determine thickness as well as distance to features within the material.
  • Compare the frequency spectra to obtain indications of homogeneity of the concrete.
  • Calculate the rate of decay of the vibrations to glean information regarding the sub-grade.

The Vu-Con™ System represents the latest technology in concrete ultrasonic analysis, allowing the engineer to seeï¿1/2 into the concrete surface.
