Standard Test Method for Flow of Grout for Preplaced-Aggregate Concrete (Flow Cone Method)
The following bibliographic material is provided to assist you with your purchasing decision:
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 fluid hydraulic cement grout through a standardized flow cone and used for preplaced-aggregate (PA) concrete; however, the test method may also be used for other fluid grouts.
1.2 It is for use with neat grout and with grouts containing fine aggregate all passing a 2.36-mm (No. 8) sieve.
1.3 This test method is intended for use with grout having an efflux time of 35 s or less.
1.4 When efflux time exceeds 35 s, flowability is better determined by flow table, found in Test Method C109/C109M, using 5 drops in 3 s.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Some values have only SI units because the inch-pound equivalents are not used in practice (Note 1).
Note 1: Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.
1.6 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.
Significance and Use
5.1 This test method is applicable to the determination of the fluidity of various fluid grout mixtures.
