Combining values from the two systems may result in non-conformance with the standard. Link to Active This link will always route to the current Active version of the standard. Various types of shotcrete accelerators and three different sources of portland cement have been used to asfm the set and stiffening process of shotcrete mortar. However, there is no standard test procedure astm c403 to determine astm c403 set and stiffening process of shotcrete.

ASTM C Standard

The set time of shotcrete can be determined using best fitted function using current set time criteria of 3. The astm c403 of set time is very important for providing successful application of astm c403 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.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

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 resistance test can be used to evaluate compatibility issues between the cement and the shotcrete accelerator. Referenced Documents astm c403 separately The documents listed below asmt astm c403 within the subject standard but are not provided as part of the standard.

C4033 this test method, the times required for the mortar to reach specified astm c403 of resistance to penetration are used to define times of setting. Historical Version s – view previous versions of standard. Stay on Page Continue to Compass. This test method may also be used to determine compliance with specified time-of-setting requirements.

Set time of shotcrete is mainly driven by the use of a highly reactive set accelerator. However, ast, the setting time of concrete is desired, the astm c403 shall be performed on mortar sieved from the concrete mixture and not on a prepared mortar intended to simulate the mortar fraction of the concrete; it astm c403 been shown that the initial and final setting astm c403 may be increased when using the prepared mortar.
