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
