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 Defective items will be either replaced or repaired. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.

Therefore, it is not advisable to compare results from specimens of different sizes or shapes. To us, complete customer satisfaction means: Remember me for one month. Search book title Enter keywords for book title search.

This test method is intended primarily for detecting significant changes in the dynamic modulus of elasticity of laboratory or field test specimens that are undergoing exposure to weathering or other types of potentially deteriorating influences.

Click xstm View the GrindoSonic Brochure. 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. Different computed values for the dynamic modulus of elasticity may result from widely different resonant frequencies of specimens of different sizes and asm of the same concrete.


Other systems offer an oscilloscope connection. Register for a trial account. Changing accelerometer positions on the test specimen is time consuming. With the Geotest pickup and driver mounted on portable stands, it is not necessary to use a test bench, which is mandatory on other apparatus.

Our large selection of inventory lets us fill your order immediately and at a completion rate that is extremely high in our industry. Referenced Documents purchase separately The documents listed below are referenced within the subject standard c2155 are not provided as part of the standard.

No other resonant frequency system includes an oscilloscope despite being strongly recommended in ASTM C paragraph 4. Geotest Catalog Request Catalog. Process control Number of programs 5 with controller unit B standard Grindosonic Number of Elevated segments 4 with B standard Aastm Optional: The apparatus consists essentially of a driver and pickup circuit.

The oscilloscope confirms that peak reading on meter is actual resonance and not a harmonic. Enter your personal account email address to request a password reset: Enter your account email address to request a password reset: To asm, complete customer satisfaction means:.

USB memory stick connection Full spectrum data storage. E Terminology for Nondestructive Examinations. The test method may also be used to monitor the development of dynamic elastic modulus with increasing maturity of test specimens.


Frequency analysis FFT calculation for detections of multiple vibrations modes Selection of zones of interest by waveband filtering Oscilloscoop function for time domain analysis Graphic visualisation of frequency domain Technical Information: Metals and Alloys Ceramics and more This item is part of the following categories: Asym of the HT Unit: Electrical power is converted by the driver into mechanical vibrations and these vibrations are imparted to the specimen under test.

Features of the MK7 Unit: When resonance occurs, the actual number is digitally displayed on the frequency counter.

Product Information

The Geotest Sonometer is the only system using a phono type cartridge as a pickup. All other units use accelerometers which require intimate contact with the test specimen. Look through our website. The difference depends, in part, on the strength level of the concrete.
