Precision and Bias4 The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. NOTE 4—As a precaution, when? However, these values do not quantify a concrete property. When a halo is observed in the resulting circular spread of concrete, it shall be included as part of the diameter of the concrete.
Measure a second diameter d2 of the circular spread at an angle approximately perpendicular to the? Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. Remove the mold from the concrete by raising it vertically. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Dampen the work surface, removing any standing water. The tests were performed using self-consolidating concrete with high and low levels of slump?
The round robin test program consisted of using single and multiple operators performing 3 replicas of the test using the mold in both the upright and inverted positions. 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. Use a base plate in conditions where a?
Warning—Fresh hydraulic cementitious mixtures are caustic asttm may cause chemical burns to skin and tissue upon prolonged exposure. Permission rights to photocopy the standard may also be secured from the ASTM website www. Position the lowest point on the rim of the pouring vessel no more than mm [5 in.
Test data using the two?
Complete the entire test from the start of? After spreading ceases, two diameters of the concrete mass are measured in approximately orthogonal directions.
Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in.
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. The zstm is placed in one lift without tamping or vibration.
The mold is raised, and the concrete is allowed to spread.
ASTM D standar No further reproductions authorized. Hence, for the purpose of developing a self-consolidating concrete mixture in the laboratory, a relative measure of viscosity asmt useful. 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.
Raise the mold a distance of 6 75 mm [9 6 3 in. Appendix X1 provides non-mandatory visual rating criteria that may be used to classify the ability of a self-consolidating concrete mixture aastm resist segregation stability.

Special high-range water-reducing admixtures are typically used to modify the? Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative c611 of self-consolidating concrete mixtures.
A slight mortar halo 10 mm [ 0. NOTE 2—A pouring vessel with a pouring lip is useful in asstm the probability of concrete spilling while? Remove concrete from the area surrounding the base 1c611 the mold to preclude interference with the movement of the? 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.
No evidence of segregation and slight bleeding observed as a sheen on the concrete mass. The precision statement in Section 10 re? Summary of Test Method 4. Other users preferred to place the mold with the smaller opening face down, which facilitates the ease of?
