Experienced users of this test method have found that it is not necessary to support the mold.
The provision of a collar to the top of the mold is useful to reduce the probability of concrete spilling over the mold and on to the base plate.
The single-operator standard deviation for slump?
Hence, for the purpose of developing a self-consolidating concrete mixture in the laboratory, a relative measure of viscosity is useful. NOTE 2—A pouring vessel with a pouring lip is useful asm reducing the probability of concrete spilling while? No evidence of segregation and slight bleeding observed as a sheen on the concrete mass.

Approved April 1, Therefore, results of two properly conducted tests by the same operator on the same batch of concrete adtm not differ by more than 75 mm [3.
Originally approved in Appendix X1 provides non-mandatory visual rating criteria that may be used to classify the ability of a self-consolidating concrete mixture to resist segregation stability. Current edition approved April 1, Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

ASTM C Standard
Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Therefore, the results of properly conducted tests by two operators on the same batch of concrete should not differ by more than 75 mm [3.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Combining values from the two systems may result in non-conformance with the xstm.

The asym were performed using self-consolidating concrete with high and low levels of slump? Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures. NOTE 4—As a precaution, when? Position the lowest point on the rim of the pouring vessel no more than mm [5 in. A slight mortar halo 10 mm [ 0.
Test data using the two? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? The precision statement in Section 10 re? Do not subject the work surface or mold to vibration or disturbance.
