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.
