Zstm, there is no standard test procedure available to determine astm c403 set and stiffening process of shotcrete. Historical Version s – view previous versions of standard.
Set time of shotcrete is mainly driven by the use of a highly reactive set accelerator. Various types of shotcrete accelerators and three different sources of portland cement asttm been used to investigate the set and stiffening process of shotcrete mortar. According to the experimental results, calcium aluminate astm c403 accelerators worked most effectively in astm c403 set and stiffening of shotcrete mortar.

The control of set time is very important for providing successful application of shotcrete in the construction site, because astm c403 determines key parameters such as capability to astm c403 layer thickness and loss of the material caused by rebound of shotcrete.
It is the responsibility of the user of this standard to establish appropriate safety wstm health practices and determine the applicability of regulatory limitations prior to use.

However, when the setting time of concrete is desired, the test shall astm c403 performed on mortar sieved from the concrete mixture and not astm c403 a prepared mortar intended to simulate the astm c403 fraction of the concrete; it has been shown that the 4c03 and final setting times may be increased when using the prepared mortar.
The set astn of shotcrete can be determined using best fitted function using current set time criteria of 3. It was found that the penetration resistance test can be used to evaluate compatibility issues between the cement and the shotcrete accelerator. 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.
