(Test Method)Standard Test Method for Flow of Fine Aggregate Concrete for Fabric Formed Concrete (Flow Cone Method)
Standard Test Method for Flow of Fine Aggregate Concrete for Fabric Formed Concrete (Flow Cone Method)
SIGNIFICANCE AND USE
4.1 This test method is applicable to the determination of the fluidity of various fluid fine aggregate concrete mixtures.
SCOPE
1.1 This test method covers a procedure, used both in the laboratory and in the field, for determining the time of efflux of a specified volume of the fine aggregate concrete through a standardized flow cone and used for fabric formed concrete (FFC); however, the test method may also be used for other fluid concrete.
1.2 It is for use with fine aggregate concrete containing fine aggregate as define in Specification C33.
1.3 This test method is intended for use with fine aggregate concrete having an efflux time 9 to 15 s.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

3. Summary of Test Method
3.1 The time of efflux of a specified volume of fine aggregate concrete from a standardized flow cone is measured.
4. Significance and Use
4.1 This test method is applicable to the determination of the fluidity of various fluid fine aggregate concrete mixtures.
5. Interferences
5.1 The presence of solid particles retained on the 9.53 mm ( ⁄8 in.) sieve or lumps of unmixed material in the fine aggregate
may cause the fine aggregate concrete to flow unevenly through the discharge tube of the flow cone or stop the flow completely.
Uneven flow will result in slower transit of the fine aggregate concrete, thereby indicating a false consistency.
6. Apparatus
6.1 Flow Cone, the dimensions as shown in Fig. 1. The body and discharge tube can be stainless steel, cast aluminum, or other
essentially noncorroding metal.
6.2 Receiving Container, capacity 2000 mL (2.114 qt), minimum.
6.3 Ring Stand or other devise, capable of supporting the flow cone in a vertical, steady position over the received container.
This test method is under the jurisdiction of ASTM Committee D18 on Soil and Rock and is the direct responsibility of Subcommittee D18.25 on Erosion and Sediment
Control Technology.
