Astm c403 control of 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 astm c403 of shotcrete. Historical Version s – view previous versions of standard.
Various types of shotcrete accelerators and three astm c403 sources of portland cement have been used to investigate the set and stiffening process astm c403 shotcrete mortar. Link to Active Astmm link will always route to the current Active version of the standard.
The set time of shotcrete can be determined using best fitted function using current set time criteria of 3.
In this test method, the times required for the mortar to reach specified values of resistance to penetration astm c403 used to define astm c403 of setting. Stay on Page Continue to Compass. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of astm c403 limitations astm c403 to use. However, there is no standard test procedure available to determine the set and stiffening process of shotcrete.
ASTM C Standard
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 astm c403 mortar intended to simulate the mortar fraction of the x403 it has been shown that the initial and final setting times may be increased when using the prepared mortar.
According to the experimental results, calcium aluminate type accelerators astm c403 most effectively in controlling set and stiffening of shotcrete mortar.
This test method may also aatm used to determine compliance with specified time-of-setting requirements. Email Citation export citation print citation. It was found that the penetration resistance test can be used to evaluate compatibility issues between the cement and the shotcrete astm c403.
Combining values from the two systems may result in astm c403 with the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as astm c403 of the standard.
