For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete mixture.
Current edition approved April 1, The precision statement in Section 10 re? Therefore, this test method is considered applicable to self-consolidating concrete having sstm aggregate up to 25 mm [1 in.
These notes and footnotes excluding those in tables and? The multi-operator standard deviation for slump?
Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in. However, these values do not quantify a concrete v1611.
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. In addition, viscositymodifying admixtures and other changes in mixture proportions and materials can also in?
NOTE 2—A pouring vessel with a pouring lip is useful in reducing the probability of concrete spilling while? Other users preferred to place the mold with the smaller opening face down, which facilitates the ease of?
Measure the diameters to the nearest 5 mm [1?
Combining values c161 the two systems may result in non-conformance with the standard. Position the lowest point on the rim of the pouring vessel no more than mm [5 in.

The concrete is placed in one lift without tamping x1611 vibration. Combining values from the two systems may result in non-conformance with the standard.
After spreading ceases, two diameters of the concrete mass are measured in approximately orthogonal directions. Historical Version s – view previous versions of standard. Test data using the two?

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. No further reproductions authorized.
Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures. Measure a second diameter d2 of the circular spread at an angle approximately perpendicular to the? Dampen the work surface, removing any standing water.
The mold is raised, and the concrete is allowed to spread. Special high-range water-reducing admixtures are typically used to modify the?
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Originally approved in Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. The single-operator standard deviation for slump?
Use a base plate in conditions where a?
Experienced users of this test method have found that it is not necessary to support the mold. Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
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. awtm
ASTM C / CM – 18 Standard Test Method for Slump Flow of Self-Consolidating Concrete
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. Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures.
Approved April 1, ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. 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.
