Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in. Use a base plate in conditions where a? When performing the slump?
The multi-operator standard deviation for slump?
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but f1611 not provided as part of the standard. 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. Raise the mold a distance of 6 75 mm [9 6 3 in.
Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns c1161 skin and tissue upon prolonged exposure. Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon asgm exposure. 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.

Link to Active This link will always route to the current Active version of the standard. Appendix X1 provides a non-mandatory procedure wstm may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures. Precision and Bias4 Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? 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.
NOTE 4—As a precaution, when? The tests were performed using self-consolidating concrete with high and low levels of slump? 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. Dampen the work surface, removing any standing water. 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 in reducing the probability of concrete spilling while? 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 property. 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.
Combining values from the two systems may result in non-conformance with the standard. Measure the diameters to the nearest 5 mm [1?
axtm Remove concrete from the area surrounding the base of the mold to preclude interference with the movement of the? 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.
Measure a second axtm d2 of the circular spread at an angle approximately perpendicular to the? Combining values from the two systems may result in non-conformance with the standard.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Other users preferred to place the mold with the smaller opening face down, which facilitates the ease of? 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.
ASTM C / CM – 18 Standard Test Method for Slump Flow of Self-Consolidating Concrete
Test data using the aetm The precision statement in Section 10 re? Approved April 1, The mold is raised, and the concrete is allowed to spread. Work Item s – proposed revisions of this standard.
No further reproductions authorized. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete mixture. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. After spreading ceases, two diameters of the concrete mass are measured in approximately orthogonal directions.
Complete the entire test from the start of? When a halo is observed in the resulting circular spread of concrete, it shall be included as part of the diameter of the concrete. Do not subject the work surface or mold to vibration or disturbance.
