Standard Test Method for Time of Setting of Concrete Mixtures by Penetration Resistance
 N C403/C403M

Annotation

This test method covers the determination of the time of setting of concrete, with slump greater than zero, by means of penetration resistance measurements on mortar sieved from the concrete mixture

This test method is suitable for use only when tests of the mortar fraction will provide the information required

This test method may also be applied to prepared mortars and grouts

This test method is applicable under controlled laboratory conditions, as well as under field conditions

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 non-conformance with the standard

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
