Penetration resistance Initial Time of Set psi Final Time of Set psi Typically to a concrete contractor, c03 time of set refers to the time at which a concrete surface can bear the weight of an individual with minimal indentation. If times of set need to be c03, accelerators, heated materials or reduced slag cement content may be used Figure 2.

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 addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. This test method may also be used to determine compliance with specified time-of-setting requirements.
