Determination of the resonant frequency of concrete.
The unit measures the resonant frequencies of the three different modes of vibration: longitudinal, transverse (flexural) and torsional.
From these, the following material characteristics, non-destructively,
can be calculated:
Suitable for cylindrical and prismatic specimens with max. diameter or side of 150 mm and length from 45 to 700 mm.
Automatic identification of the resonance frequency. Large easy-to-view display for data analysis of time domain and frequency spectrum signals.
Data can be stored and uploaded to a PC for further analysis and
inclusion in the report. Fast and easy-to-use system.
The principle used in this meter is based upon the determination of the fundamental resonant frequency of vibration of a specimen generated by an impact and sensed by an accelerometer. The frequency spectrum is computed and displayed by the meter.
Durability of concrete:
The determination of flexural resonance is very important when studying the degradation of concrete under accelerated freezing and thawing cycles and aggressive environments on concrete specimens.
