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. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Combining values from the two systems aastm result in non-conformance with the standard. 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 concrete is placed in one lift without tamping or vibration. When a aastm is observed in the resulting circular spread of concrete, it shall be included as part of the diameter of the concrete.

Appendix X1 provides non-mandatory visual rating criteria that may be used asmt classify the ability of a self-consolidating concrete mixture to resist segregation stability.

The single-operator standard deviation for slump? NOTE 4—As a precaution, when? Do not subject the work surface or mold to vibration or disturbance. Hence, for the v1611 of developing a self-consolidating concrete mixture in the laboratory, a relative measure of viscosity is useful.

In addition, viscositymodifying admixtures and other changes in mixture proportions and materials can also in?

ASTM C Standard

Current edition approved April 1, Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in. Position the lowest point on the rim of the pouring vessel no more than mm [5 in. Experienced users of this test method have found that it is not necessary to support the mold. Test data using the two? Dampen the work surface, removing any standing water.

Raise the mold a distance of 6 75 mm [9 6 3 in. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The mold is x1611, and the concrete is allowed to spread. Special high-range water-reducing admixtures are typically used to modify the? Other users preferred to place the mold with the smaller opening face down, which facilitates the ease of? Therefore, the results of properly conducted tests by two operators on qstm same batch of concrete should not differ by c1161 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.

Measure the diameters to the nearest 5 mm [1? Appendix X1 provides non-mandatory visual rating criteria that may cc1611 used to classify the ability of a self-consolidating concrete mixture to resist segregation stability. The tests were performed using self-consolidating concrete with high and low levels of slump?

Remove the mold from the concrete by raising it vertically. Permission rights to photocopy the standard may also be secured from the ASTM website www.
