Various types of shotcrete accelerators and three different sources of portland cement have been used to investigate the set and stiffening process of shotcrete mortar.

However, when the setting time of concrete is desired, the test shall be performed on mortar sieved from the concrete mixture astm c403 not on a prepared mortar intended to simulate the mortar fraction of the concrete; it has been shown that astm c403 initial and final setting times may be increased when using the prepared mortar.


According to the experimental results, calcium aluminate type accelerators worked most effectively in controlling set and stiffening of shotcrete mortar.

The set time of shotcrete can be determined using best fitted function using current set time criteria astm c403 3. In this test method, the astm c403 required for the mortar to reach specified values of resistance to penetration are used to define times of setting.

ASTM C Standard

The control of set astm c403 is very important for providing successful application of shotcrete in the construction site, because it determines key parameters such as capability to increase layer astm c403 and loss of the material caused by rebound of shotcrete. This test method may also be used to determine compliance with specified time-of-setting requirements.

Combining values from the two systems may result in non-conformance with the standard. The values stated in each system may not be exact equivalents; therefore, each system shall astm c403 used independently of the other. It is the responsibility of astm c403 user of this standard to establish asttm safety and health practices and determine the applicability of regulatory limitations prior to use.
