TMH AND TRH DOCUMENTS
  • The production of essential normative reference
    methods which are being done in the next phase
    were needed before SABS can publish Sets A to C.
  • Work on next phase (Sets 1 to 5) is progressing
    well
  • SET 1
  • 3001-AG1 The particle size analysis of
    aggregates by sieving.
  • 3001-AG3 The determination of the flakiness
    index of coarse aggregate.

    crushing value) of coarse aggregates.

    density, apparent relative density and water
    absorption of material retained on the 5mm sieve.
  • 3001-AG21 The determination of the dry bulk
    density, apparent relative density and water
    absorption of material passing the 5mm sieve.
  • Needs to be given priority as it is required
    as a normative reference for methods in
    Pilot Stage.
