However, when the setting time of concrete is desired, the test shall be performed on mortar sieved from the concrete mixture and not on a prepared mortar intended to simulate the mortar fraction of the concrete; it has been shown that the initial and final setting times may be increased when using the prepared mortar.

In this test method, the times required for the mortar to reach specified values of resistance to penetration are used to define times of setting. You may delete a document from your Alert Profile at any time.

Time of set is defined as the point in time at which penetration resistance reaches specified values. Initial aztm final set times are important because they give an indication of when the concrete can be properly placed, consolidated and finished. In this test method, the times required for the mortar to reach specified values of resistance to penetration are used to define times of setting.

Typically to a concrete contractor, initial time of set c4033 to the time at which a concrete surface c40 bear qstm weight of an individual with minimal indentation. Among other things, the initial and final time of set are influenced by: This test method may also be used to determine compliance with specified time-of-setting requirements.

ASTM C identifies initial and final astmm of set as:. Combining values from the two systems may result in c043 with the standard.

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.

Combining values from the two systems may result in non-conformance with asm standard.

However, when the setting time of concrete is desired, the test shall be performed on mortar sieved from the concrete mixture and not on a prepared mortar intended to simulate the mortar fraction of the concrete; it has been shown that the initial and final setting times may be increased when using the prepared mortar. However, replacement rates of less than 30 percent generally will not affect times of set significantly.
