Methods of testing concrete Determination of setting time of fresh concrete, mortar and grout by penetration resistance
Standards Australia
Specifies procedures for determining the initial and final setting times of mortar sieved from fresh concrete mix, the slump of which is greater than zero, using penetration resistance needles. This Standard is also applicable to fresh mortar and grout.

This Standard describes the procedures for determining the initial and final setting times of mortar sieved from fresh concrete mix, the slump of which is greater than zero, using penetration resistance needles. This method is also applicable to fresh mortar and grout.
NOTES:
1 As the hardening of concrete is a gradual process, any definition of setting time must necessarily be arbitrary.
2 This method is primarily intended to be used as a means for comparing setting times under the same conditions in the laboratory.
3 This method may be used to determine the setting characteristics at a standard temperature (23 ¦2¦C), at some other specified temperature or alternatively to determine the setting time-temperature relationship.
4 This method may be used to estimate setting times of specific concretes, mortars or grouts in the field.
