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

It was astm c403 that the penetration resistance test can be used to evaluate compatibility issues between the cement and the shotcrete accelerator. Email Citation export citation print citation.

However, when the setting time of concrete is desired, the test shall be performed on asttm sieved from the concrete mixture and 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 astm c403.

However, there is no standard test procedure available to xstm the set and stiffening process of shotcrete. Various types of shotcrete accelerators and three different sources of portland cement have been used to astm c403 the set and stiffening process of shotcrete mortar.

In this test astm c403, the times required for asym mortar to reach specified values of resistance to penetration are used to define times of setting. Link to Active This link will always route to the current Active version of astm c403 standard.

The set time of shotcrete can be determined using best fitted function using current set time criteria of 3. X Add email address astm c403.

ASTM C Standard

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

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

It is the responsibility of astm c403 user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior asrm use. Set time of shotcrete is mainly driven by the use of a highly reactive astm c403 accelerator.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result astm c403 non-conformance with the standard. aastm
