For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete mixture.

Current edition approved April 1, The precision statement in Section 10 re? Therefore, this test method is considered applicable to self-consolidating concrete having sstm aggregate up to 25 mm [1 in.

These notes and footnotes excluding those in tables and? The multi-operator standard deviation for slump?

Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in. However, these values do not quantify a concrete v1611.

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