ASTM C Standard
This test method may also be used to determine compliance with specified time-of-setting requirements. Set time of shotcrete is astm c403 asfm by the use of a highly reactive set accelerator.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is the responsibility of astm c403 user of this standard to astm c403 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. It was found that the penetration resistance test astn be used to evaluate compatibility issues between the cement and the shotcrete accelerator.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The set time astm c403 shotcrete can be determined using best fitted function using current set time criteria of 3.
However, when the setting time of concrete is desired, the test shall be performed on mortar sieved from the concrete mixture and not astm c403 a prepared mortar intended to simulate the mortar fraction of the concrete; it has been shown that the initial and astm c403 setting times may be increased when using the prepared mortar.

X Add email address send. Astm c403 to the experimental results, calcium aluminate type astm c403 worked most effectively in controlling set and stiffening of shotcrete mortar. The control astm c403 set time is very important for providing successful application of shotcrete in the construction site, because it determines key parameters such as capability to increase layer thickness and loss of the material caused by rebound of shotcrete.

In this test method, the times required for the mortar to reach specified values of resistance to astm c403 are used to define times of setting. 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, there is no standard test procedure available astm c403 determine the set and stiffening process of shotcrete.
