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.
  • 3001-AG10 Aggregate crushing value of coarse aggregates.
  • 3001-AG11 FACT value (10% fines aggregate crushing value) of coarse aggregates.
  • 3001-AG20 The determination of the dry bulk 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.
