适用范围：This Tanzania Standard specifies:a) Method to be used for determining consistency of concrete by slump test.b) A simplified method for determining the work-ability of concrete for all degrees both at the site and in the laboratory by the use of a compaction device.c) Method for determining the workability ofconcrete by the compacting factor test which isparticularly useful for concrete mixes of lowworkability which may consistently fail to givetrueslump.d) Method for determining the workability of concrete by 'V—B' consistometer test, particu-larly useful as alternative to the comnpacting factor test for concrete mixers of low workability and for air-entrained concrete.e) Method for determining the mass per cubic meter of fresh concrete and gives formulae for calculating the volume of concrete per batch and the cement content per cubic meter.f) Procedure for determining the air content of fresh concrete by a pressure method.g) The method of determining the mass propor-tions of the consistuents of fresh cpncrete.Caution should be exercised in the applicationof the test to concrete made with lightweightaggregate.
