Grain size distribution
Evaluation and presentation of grain size distribution.
  • wet analysis
  • sieve analysis
  • combined wet and sieve analysis,
with output as a protocol form or as a diagram

Capabilities:

  • Presentation of grain size categories as %
  • Calculation of uniformity coefficients and coefficients of curvature
  • Filter criteria according to Terzaghi/USBR
  • Determination of transmission constant according to Hazen, Beyer, Mallet/Paquant, Seelheim
  • Determination of grain characteristic number
  • Soil type according to SEP
  • Soil group and frost resistance according to USCS.
  • Angle of internal friction (estimation according to Lang/Huder)
  • Choice of defined sieves
  • Input of sieve refuse in [g] or in [%]
  • User definable densimeter values
  • Sieving before or after sedimentation
  • Grain distribution can be graphically altered (e.g. adjustment of transition from wet branch to sieve branch)
  • Free design of form
