Test data using the two?

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.

A slight mortar halo 10 mm [ 0. However, these values do not quantify a concrete property.

ASTM C / CM – 18 Standard Test Method for Slump Flow of Self-Consolidating Concrete

Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in. Complete the entire test from the start of? Measure the diameters to the nearest 5 mm [1? Historical Version s – view previous versions of standard. Approved April 1, No evidence of segregation and slight atm observed as a sheen on the concrete mass.

Originally approved in When performing the slump?

If you feel that your comments have not received a fair hearing c11611 should make your views known to the ASTM Committee on Standards, at the address shown below. 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.

Experienced users of this test method have found that it is not necessary to support the mold.

These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. Combining values from the two systems may result in non-conformance with the standard. Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.

When the base plate is used, position and shim the base plate so that it is fully supported. It is the responsibility of the user of this standard to establish appropriate safety and health practices aatm determine the applicability of regulatory limitations prior to use.

ASTM C Standard

The multi-operator standard deviation for slump? When a halo is observed in the resulting circular spread of concrete, it shall be included as part of the diameter of the concrete. Dampen the work surface, removing any standing water. For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete mixture.

The tests were performed using self-consolidating concrete with high and low levels of slump? 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 asgm use. The precision statement in Section 10 re?

In addition, viscositymodifying admixtures and other changes in mixture proportions and materials can also in? Summary of Test C111 4. Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in.

Remove the mold from the concrete by raising it vertically.

ASTM C1611

Do not subject the work surface or mold c611 vibration or disturbance. Combining values from the two systems may result in non-conformance with the standard.

The mold is raised, and the concrete is allowed to spread. Appendix X1 provides non-mandatory visual rating aatm that may be used to classify the ability of a self-consolidating concrete mixture to resist segregation stability.

Other users preferred to place the mold with the smaller opening face down, which facilitates the ease of? Your comments will receive careful consideration at a meeting ashm the responsible technical committee, which you may attend.

ASTM D standar Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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. Individual sstm single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

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.

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. Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures.

Current edition approved April 1, Remove concrete from the area surrounding the base of the mold to preclude interference with the movement of the? 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?

Ensure an even distribution of concrete, without rodding the concrete or tapping the sides of the mold, while? Special high-range water-reducing admixtures are typically used to modify the?

NOTE 4—As a precaution, when? Hence, for the purpose of developing a self-consolidating concrete mixture in the laboratory, a relative asttm of viscosity is useful. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
