Testing of concrete, cementitious and rocks

The Sonelastic® System for concrete, cementitious materials and rocks complies with ASTM C215-19 standard test method for the determination of the dynamic modulus of elasticity (Ed); it also complies with Annex B of the ABNT NBR 8522-1:2021 standard for the estimation of the chord modulus (Ec) from the dynamic modulus applying Popovics model. Estimating the Ec from the Ed determined by Sonelastic is as practical and accurate as to determine the Ec via static test.

Sonelastic® Systems employ the Impulse Excitation Technique, which is non-destructive and provides highly precise and reproducible results. The test is fast, to measure three specimens it takes around 6 minutes including weighing and dimensional measurements. The typical uncertainty is 1.5% and the reproducibility 0.6%. (Ref.: ABNT NBR 8522-2:2021, pg. 2).

The system shown above includes: Sonelastic® software, laptop, signal acquisition USB module ADAC, SA-BC adjustable support for bars and cylinders, set of manual impulse devices, CA-DP acoustic sensor with vertical base, protective cover, calibration certificate traceable to the SI and ruler for marking the nodal lines on 100 x 200 mm cylindrical specimens. This system optional items are the IED automatic impulse device and the sturdy tripod.

In addition to the modulus of elasticity, Sonelastic® Systems also allow the simultaneous determination of the shear modulus, Poisson's ratio, P and S waves velocity and damping of concrete, cementitious materials and rocks. The measurement of damping is sensitive to the presence and evolution of cracks and micro-cracks.

Applications

Sonelastic® Systems have a wide range of applications for concretes and cementitious materials:
  • Quality control of concrete manufacturing;
  • Curing and drying monitoring;
  • Refining finite element modeling and analyses (FEA/FEM);
  • Study of damage caused by mechanical stress and fatigue;
  • Study of degradation processes by thermochemical treatments and weathering.

Rocks and minerals

Sonelastic® Systems are able to measure the elastic moduli and damping of rocks and minerals, the main applications are:
  • Classification;
  • Quality control;
  • Geological soundings;
  • Evaluation of thermochemical damage;
  • Characterization of mechanical properties for drilling and mining optimization.

Traceable calibration

Sonelastic® Systems include calibration certificate with traceability to the International System of Units - SI.

Treaceability to the International System of Units - SI

For new systems, the calibration certificate is provided on demand and at no additional cost. For renewals, ATCP offers the service at competitive prices. The typical turnaround time for the calibration service is two business days.
