ASTM C Setting of Concrete Mix by Penetration Resistance | CTL Grp

Various types of shotcrete accelerators and three different sources of portland cement astm c403 been used to investigate the set and stiffening process of shotcrete mortar.

Stay on Page Continue to Compass. Set astm c403 of shotcrete is mainly driven by the use of a highly reactive set accelerator.

Link to Active This link will always route to the current Active version of the standard. However, when the setting time of concrete is desired, the test shall be performed on mortar sieved from the astm c403 mixture and not on a prepared mortar intended to simulate the mortar fraction astm c403 the concrete; it has been shown astm c403 the initial and final setting times may be increased when using the prepared mortar.

The aztm stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

However, there is no standard test procedure available to determine the set and stiffening process of shotcrete. The astm c403 time of astm c403 can be determined using best fitted function using current set time criteria of 3. According to the experimental results, calcium aluminate type accelerators worked most effectively in controlling set and stiffening of shotcrete mortar.

It was found that the penetration astm c403 test can be used to evaluate compatibility issues between the cement and the shotcrete accelerator.

Combining values from the two systems may result in astm c403 with the astm c403. This test method may also be used to determine compliance with specified time-of-setting requirements. In this test method, the times required for the mortar to reach specified values of resistance to penetration are used to define times of setting.

The control of set time is very important astm c403 providing successful application of shotcrete in the construction site, because it determines key astm c403 such as capability to increase layer thickness and loss of the material caused by rebound of shotcrete.
