ASTM D standar A number in parentheses indicates the year of last reapproval.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

These notes and footnotes excluding those in tables and? 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. Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged f1611.

Current edition approved April 1, Originally approved in Summary of Test Method 4. The concrete is placed in one lift without tamping or vibration. The mold is raised, and the concrete is allowed to spread.

After spreading ceases, two diameters of the concrete mass are measured in approximately orthogonal directions. Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in. 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. Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures.

No further reproductions authorized. 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. Other users preferred to place the mold with the smaller opening face down, which facilitates the ease of? The precision statement in Section 10 re? Test data using the two? NOTE 4—As a precaution, when? Experienced users of this test method have found that it is not necessary to support the mold.

When the base plate is used, position and shim the base plate so that it is fully supported. Dampen the work surface, removing any standing water.

Do not subject the work surface or mold to vibration or disturbance. Position xstm lowest point on the rim of the pouring vessel no more than mm [5 in. Ensure an even distribution of concrete, without rodding the concrete or tapping the sides of the mold, while? Remove concrete from the area surrounding the base of the mold to preclude interference with the movement of the?

Remove the mold from the concrete by raising it vertically. Raise the mold a distance of 6 75 mm [9 6 3 asmt.

Complete the entire test from the start of? When a asstm is observed in the resulting circular spread of concrete, it shall be included as part of the diameter of the concrete. Measure a second diameter d2 of the circular spread at an angle approximately perpendicular to the? Measure the diameters to the nearest 5 mm [1?

Precision and Bias4 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. astmm

The tests were performed using self-consolidating concrete with high and low levels of slump? The single-operator standard deviation for slump?

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. The multi-operator standard deviation for slump? 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.

Hence, for the purpose of developing a self-consolidating concrete mixture in the laboratory, a relative measure of viscosity is useful. When performing the slump? For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete mixture.

Special high-range water-reducing admixtures are typically used to modify the? In addition, viscositymodifying admixtures and other changes in mixture proportions and materials can also in?

No evidence c611 segregation and slight bleeding observed as a sheen on the concrete mass. A slight mortar halo 10 mm [ 0.

However, these values do not quantify a concrete property.
