ASTM C597 − 09 Standard Test Method for Pulse Velocity Through Concrete

Scope of ASTM C597 − 09 Standard Test Method for Pulse Velocity Through Concrete

1.1 This test method covers the determination of the propagation velocity of longitudinal stress wave pulses through concrete.

This test method does not apply to the propagation of other types of stress waves through concrete.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

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

Significance and Use of ASTM C597 − 09 Standard Test Method for Pulse Velocity Through Concrete

5.1 The pulse velocity, V, of longitudinal stress waves in a concrete mass is related to its elastic properties and density according to the following relationship:
V 5Œρ ~1E1µ~1!~21 2µ!2 µ! (1)
where:
E = dynamic modulus of elasticity, µ = dynamic Poisson’s ratio, and ρ = density.

5.2 This test method is applicable to assess the uniformity and relative quality of concrete, to indicate the presence of voids and cracks, and to evaluate the effectiveness of crack repairs.

It is also applicable to indicate changes in the properties of concrete, and in the survey of structures, to estimate the severity of deterioration or cracking.

When used to monitor changes in condition over time, test locations are to be marked on the structure to ensure that tests are repeated at the same positions.
