ASTM C Standard

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. The tests were performed using self-consolidating concrete with high and low levels of slump? Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.

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

Do not subject the work surface or mold to vibration or disturbance. Ensure an even distribution of concrete, without rodding the concrete or tapping the sides of the mold, while? Complete the entire test from the start of? In addition, viscositymodifying admixtures and other changes in mixture proportions and materials can also in?

A slight mortar halo 10 mm [ 0. Measure a second diameter d2 of the circular spread at an angle approximately perpendicular to the? Historical Version s – view previous versions of standard. No evidence of segregation and slight bleeding observed as a sheen on the concrete mass. 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.

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.

When a halo is observed in the resulting circular spread of concrete, it shall be included as part of the diameter of the concrete. These notes and footnotes excluding those in tables and?

ASTM C1611

No further reproductions authorized. After spreading ceases, two diameters of the concrete mass are measured in approximately orthogonal directions. Experienced users of this test method have found that it is not necessary to support the mold. V1611 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.

Test data using the two? The concrete is placed in one lift without tamping or vibration.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. However, these values do not quantify a concrete property.

Users of this standard are expressly advised that determination of the f1611 of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Originally approved in Approved April 1, Other users preferred to place asgm mold with the smaller opening face down, which facilitates the ease of? Combining values from the two systems may result in non-conformance with the standard.

Precision and Bias4 The precision statement in Section 10 re? 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. For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete mixture.
