For similar materials, this time period, termed T50, gives an indication of the relative viscosity of the self-consolidating concrete mixture. Dampen the work surface, removing any standing water. Therefore, this test method is considered applicable asfm self-consolidating concrete having coarse aggregate up to 25 mm [1 in. Therefore, this test method is considered applicable to self-consolidating concrete having coarse aggregate up to 25 mm [1 in.

ASTM C Standard

Approved April 1, The single-operator standard deviation for slump? A slight mortar halo 10 mm [ 0. Raise the mold a distance of 6 75 mm [9 6 3 in. The concrete is placed in one lift without tamping or vibration. 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.

Position the lowest point on the rim of the pouring vessel no more than mm [5 in. 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.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Use a base plate in conditions where a? Ensure an even distribution of concrete, without rodding the aetm or tapping the sides of the mold, while?

The values stated in each system may astk be exact equivalents; therefore, each system shall be used independently of the other. The mold is raised, and the concrete is allowed to spread.

Remove the mold from the concrete by x1611 it vertically. In addition, viscositymodifying admixtures and other changes in mixture proportions and materials can also in? The precision statement in Section 10 re? When performing the slump? It is the responsibility of the user of this standard to asstm appropriate safety, health, and environmental 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 exposure. Work Item s – proposed revisions of this standard. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you d1611 attend. Complete the entire test from the start of? Special high-range water-reducing admixtures are typically used to modify the?
