Page Count: 5
ICS Code (Concrete and concrete products): 91.100.30
scope:

1.1 These test methods cover the determination of the in-place density of unhardened and hardened concrete by gamma radiation. For notes on the nuclear test see Appendix X1.

1.2 Two test methods are described, as follows:

Section Test Method A---Direct Transmission 7 Test Method B---Backscatter 8

1.3 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents of inch-pound units may be approximate.

1.4 This standard does not purport to address all of the safety problems, 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.

Standard Test Methods for In-Place Density of Unhardened and Hardened Concrete, Including Roller Compacted Concrete, By Nuclear Methods
These test methods are useful as rapid, nondestructive techniques for the in-place determination of the density of unhardened concrete. The backscatter test method is also useful for the same purpose...
