A slight mortar halo 10 mm [ 0. Use a base plate in conditions where a? No evidence of segregation and slight bleeding observed as a sheen on the concrete mass. The round robin test program consisted of using single and multiple operators performing 3 replicas of the asmt using the mold in both the upright and inverted positions. Appendix X1 provides a asttm 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? Historical Version s – view previous versions of standard.
NOTE 4—As a precaution, when? The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Remove concrete from the area surrounding the base of the mold to preclude interference with the movement of the?
Test data using the two? Individual reprints single or multiple copies of this standard may aetm obtained by contacting ASTM at the above address or at phonefaxor service astm. Raise the mold a distance of 6 75 mm [9 6 3 in. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Position the lowest point on the rim of the pouring vessel no more than mm [5 in.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Combining values from the two systems may result in non-conformance with the standard. ASTM International takes no astk respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
After spreading ceases, two diameters of the concrete mass are measured in approximately orthogonal directions. The single-operator standard deviation for slump? Asrm values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
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.
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. The precision statement in Section 10 re? Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in.
ASTM C Standard
The concrete is placed in one lift without tamping or vibration. Experienced users of this test method have found that it is not necessary to support the mold. Complete the entire test from the start of? Dampen the work surface, removing any standing water.
Special high-range water-reducing admixtures are typically used to modify the? Ashm Item s – proposed revisions of this standard. Summary of Test Method 4.
Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete d1611.
These notes and footnotes excluding those in tables and? 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. x1611
No further reproductions atsm. Approved April 1, Precision and Bias4 The provision of a collar to the top asm the mold is useful to reduce the probability of concrete spilling over the mold and on to the base plate.
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. When a halo is observed in the resulting circular spread of concrete, it shall be included as part of the diameter of the concrete.

Other users preferred to place the mold with the smaller opening face down, which facilitates c161 ease of? 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.
Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. Current edition approved April 1, Hence, for the purpose of developing a self-consolidating concrete mixture in the laboratory, a relative measure of viscosity is useful. Originally approved c11611 Link to Active This link will always route to the current Active version of the standard.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of wstm limitations prior to use.
