These notes and footnotes excluding those in tables and? Ensure an even distribution of concrete, without rodding the asmt or tapping the sides of the mold, while? Awtm 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. No further reproductions authorized.

Special high-range water-reducing admixtures c16111 typically used to modify the? Combining values from the two systems may result in non-conformance with the standard. Summary of Test Method 4. Measure a second diameter d2 of the circular spread at an angle approximately perpendicular to the?

Other users preferred to place the mold with the smaller opening face down, which facilitates the ease of? Dampen the work surface, removing any standing water. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. Raise the mold a distance of 6 75 mm [9 6 3 in.

Precision and Bias4 The precision statement in Section 10 re? Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. 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 to use.

ASTM C Standard

Appendix X1 aatm a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures. Do not subject the work surface or mold to vibration or disturbance. When the base plate is used, position and shim the base plate so that it is fully supported.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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. In addition, viscositymodifying admixtures and other changes in mixture proportions and materials can also in? Current edition approved April 1, ASTM D standar Appendix X1 provides a non-mandatory procedure that may be used to provide an indication of relative viscosity of self-consolidating concrete mixtures.

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM asym the above address or at phonefaxor service astm. Remove the mold from the concrete by raising it vertically.

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. Hence, for the purpose of developing a self-consolidating concrete mixture in astn laboratory, a relative measure 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. When a halo is observed in the resulting circular spread of concrete, it shall be included as part of the diameter of the concrete.

NOTE 2—A pouring vessel with a pouring lip is useful in reducing the probability of concrete spilling while? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Measure the diameters to the nearest 5 mm [1? A slight mortar halo 10 mm [ 0. For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete mixture. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

Position the lowest point on the rim of the pouring vessel no more than mm [5 in. Appendix X1 provides non-mandatory visual rating criteria that may be used to classify the ability of a self-consolidating c6111 mixture to resist segregation stability.
