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 to use. Combining values from the two systems may result in non-conformance astm c403 the standard.

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

In this test astm c403, the c4003 required for the mortar to reach specified values of resistance to penetration are used to define times of astm c403.

Historical Version s – view previous astm c403 of standard. The control of astm c403 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.

astm c403 However, there is no standard astm c403 procedure available to determine the set and stiffening process of shotcrete. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. X C4033 email address send.

Various types of astm c403 accelerators and three different sources of portland cement have been used to investigate the set and stiffening process of shotcrete mortar. It was found that the penetration resistance test can be used to evaluate compatibility issues between the cement and the shotcrete accelerator.

The set time of shotcrete can be determined using best fitted function using current set time criteria of 3. This test method may also be used to determine compliance with specified time-of-setting requirements.

astm c403 However, when the setting time of concrete astm c403 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 final setting times may be increased when using the prepared mortar.

Set time of shotcrete is mainly driven by the use of a highly reactive set accelerator.
