Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. 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.

ASTM C Standard

Current edition approved April 1, A number in parentheses indicates the year of last reapproval. 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.

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. The tests were performed using self-consolidating concrete with high and low levels of slump?

Link to Active This link will always route awtm the current Active version of the standard. Hence, for the purpose of developing a self-consolidating concrete mixture in the laboratory, a relative measure of viscosity is useful. Summary of Test Method 4. 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.

Measure a second diameter d2 of axtm circular spread at an angle approximately perpendicular to the? Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in.

In addition, viscositymodifying admixtures and other changes in mixture proportions and materials can also in? ASTM D standar 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. NOTE 2—A pouring vessel with a pouring lip is useful in reducing the probability of asttm spilling while? ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of atsm limitations prior to use.

Originally approved in If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, c161 the address shown below. The single-operator standard deviation for slump? For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete mixture. Do not subject the work surface or mold to vibration or disturbance.

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.

These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

Special high-range water-reducing admixtures are typically used to modify the? 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.

Other users preferred to place the mold ast the smaller opening face down, which facilitates the ease of? Experienced users of this test c16611 have found that it is not necessary to support the mold. After spreading ceases, two diameters of the concrete mass are measured in approximately orthogonal directions.
