Standard Test Method for Time of Setting of Concrete Mixtures by Penetration Resistance
1.1 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.
1.2 This test method is suitable for use only when tests of the mortar fraction will provide the information required.
1.3 This test method may also be applied to prepared mortars and grouts.
1.4 This test method is applicable under controlled laboratory conditions, as well as under field conditions.
1.5 The values stated in either inch-pound units or SI units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.
1.6 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.
