Standard Test Method for Fundamental Transverse, Longitudinal, and Torsional Resonant Frequencies of Concrete Specimens. A non-destructive sonic method. Fundamental Transverse, Longitudinal, and Torsional Resonant Frequencies of Concrete Specimens. All the Controls products ASTM C standard. Enter now!.
This apparatus closely follows design parameters set up over 40 years ago by the Portland Cement Association research laboratories. The original X215 design has been modified by changing to solid state circuitry and addition of a built-in cathode ray oscilloscope. A very detailed instruction manual accompanies each sonometer. The test method may also be used to monitor the development of dynamic elastic modulus with increasing maturity of test specimens.

Proof of claim is required. The value of the dynamic modulus of elasticity obtained by this test method will, in general, be greater than the static modulus of elasticity obtained by using Test Method C It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
ASTM C, C The Geotest Sonometer is one of several devices now being offered for determining changes in resonant frequency of concrete specimens subjected to alternate cycles of freezing and thawing with C Freeze-Thaw Apparatus.
Are you sure you want to empty the cart? F Standard Specification for Driven Fasteners: Geotest Catalog Request Catalog. The oscilloscope confirms that peak reading on meter is actual resonance and not a harmonic.
E-Meter for Flexural Resonance of Concrete
This test method is intended primarily for detecting significant changes in atm dynamic modulus of elasticity of laboratory or field test specimens that are undergoing exposure to weathering or other types of potentially deteriorating influences.
The chassis measures 17x14x11″. Significance and Use This test method is intended primarily for detecting significant changes in the dynamic modulus of elasticity of laboratory or xstm test specimens that are undergoing exposure to weathering or other types of potentially deteriorating influences.

With the Geotest pickup and driver mounted on portable stands, it is not necessary to use a test bench, which is mandatory on qstm apparatus. This allows for greater flexibility in testing.

Enter your personal account email address to request a password reset: Different computed values for the dynamic modulus of elasticity may result from widely different resonant frequencies of specimens of different sizes and shapes of the same concrete. Search book title Enter keywords for book title search. The difference depends, in part, on the strength level of the concrete.
All claims must be made within 30 days of purchase. Look through our website. The Geotest Sonometer is the only system using a phono type cartridge as a pickup. The actual frequency is displayed on a built-in digital counter.
Other systems offer an oscilloscope connection. Our extensive inventory is yet another way to keep you satisfied. Advanced Search Search Tips. The apparatus consists essentially asgm a driver and pickup circuit.
