Standard Test Method for Flow of Grout for Preplaced-Aggregate Concrete (Flow Cone Method)
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, using 5 drops in 3 s.
1.5 The values stated in SI units are to be regarded as the standard.
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.
