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 asstm the base plate. The multi-operator standard deviation for slump? Do not subject the work surface or mold to vibration or disturbance. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The values stated atsm each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Combining values from the two systems may result in non-conformance with the standard.

In addition, viscositymodifying admixtures and other changes in mixture proportions and materials can also in? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
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. Individual reprints single or multiple copies of asmt standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
A number in parentheses indicates the c6111 of last reapproval. However, these values do not quantify a concrete property. Ensure an even distribution ast, concrete, without rodding the concrete or tapping the sides of the mold, while?
ASTM C / CM – 18 Standard Test Method for Slump Flow of Self-Consolidating Concrete
No further reproductions authorized. The concrete is placed in one lift without tamping or vibration. Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures. No evidence of segregation and slight bleeding observed as a sheen on the concrete mass. Remove the mold from the concrete by raising it vertically.
When performing the slump? The mold is raised, and the concrete is allowed to spread.
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. When a halo is observed in the resulting circular spread of concrete, it shall be included as part of the diameter of the concrete.
Use a base plate in conditions where a?
Summary of Test Method 4. Current edition approved April 1, Approved April 1, Experienced users of this test method have found that it is not necessary to support the mold. Historical Version s – view previous versions of standard.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Hence, for the purpose of developing a self-consolidating concrete mixture in the laboratory, a relative measure of viscosity is useful. Position the lowest point on the rim of the pouring vessel no more than mm [5 in.
Complete the entire test from the start of? ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. sstm
After spreading ceases, two diameters of the concrete mass are measured in approximately orthogonal directions. 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.
Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures. Therefore, results of two properly conducted tests by the same operator 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.
