What we do

Aggregate testing capabilities include:

Conventional determination of specific gravity and absorption of coarse and fine aggregates

  • Determination of specific gravity and absorption of coarse and fine aggregate via vacuum sealing device (i.e. CoreLok method)
  • Determination of specific gravity and absorption of fine aggregate via infrared SSD method (i.e. SSDetect method)
  • Fractured Face determination
  • Flat and elongated particles
  • Sand equivalent
  • Methylene blue
  • Fine aggregate angularity
