ASTM C803/C803M − 03 Reapproved 2010 Standard Test Method for Penetration Resistance of Hardened Concrete

ASTM C803/C803M − 03 Reapproved 2010 Standard Test Method for Penetration Resistance of Hardened Concrete

Scope
1.1 This test method covers the determination of the resistance of hardened concrete to penetration by either a steel probe or pin.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Combining values from the two systems may result in nonconformance with the 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.

For specific hazard statements, see Section 7.

Significance and Use
5.1 This test method is applicable to assess the uniformity of concrete and to delineate zones of poor quality or deteriorated concrete in structures. 5.2 This test method is applicable to estimate in-place strength, provided that a relationship has been experimentally established between penetration resistance and concrete strength.

Such a relationship must be established for a given test apparatus (see also 9.1.5), using similar concrete materials and mixture proportions as in the structure.

Use the procedures and statistical methods in ACI 228.1R for developing and using the strength relationship
