11、er of thepatty is determined and compared to established criteria.5.Significance and Use5.1 This test method is intended to provide the user with aprocedure to determine the fluidity of CLSM mixtures for useas backfill or structural fill.5.2 This test method is considered applicable to freshCLSM con

13、 section on Additional Procedures forLarge Maximum size Aggregate Concrete in Practice C 172.NOTE1Removing the coarse aggregate will alter the characteristicsof the mix and therefore will give information only about the remainingmaterial.It is suggested that for mixes containing coarse aggregate 19.
