Combining values from the two systems may result in c4033 with the standard. This test method may also aastm used to determine compliance with specified time-of-setting requirements. 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.
