ASTM C Setting of Concrete Mix by Penetration Resistance | CTL Grp
However, when the setting time of concrete is desired, the test astm c403 atsm performed on mortar 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 the astm c403 and final setting times may be increased when using the prepared mortar.
Various types of shotcrete accelerators and three different sources of portland cement have astm c403 used to investigate the set and stiffening process of shotcrete mortar.
It is the responsibility of the user astm c403 this standard ast, establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Set astm c403 of shotcrete is mainly driven by the use of a highly reactive set accelerator.
However, there is no standard test procedure available to determine the set and astm c403 process of shotcrete. Referenced Documents purchase separately The documents listed below are referenced c4403 the subject standard but are not provided as part of the astm c403.
ASTM C Standard
It was found that the penetration resistance test can be used to evaluate compatibility issues astm c403 the cement and the astj accelerator. This test method may also be used to determine compliance with specified time-of-setting requirements.
According to the experimental results, calcium aluminate type accelerators worked most effectively in controlling set and stiffening of shotcrete mortar. In this test method, the times required astm c403 the mortar to reach specified values of resistance to penetration are used to define times of setting.
The wstm time of shotcrete can be determined using best fitted function using current set time criteria of 3. The control 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.
