Grain size distribution test



Grain size test is used to identify the percentage of different grain sizes contained within a soil where the mechanical or sieve analysis is performed to determine the distribution of the coarser, larger-sized particles, and the hydrometer method is used to determine the distribution of the finer particles.

CiviLab offers all mesh sizes available in:

  • ASTM E11;
  • ISO 565/3310-1.

Our soil laboratory software “CiviLab” facilitates the processing of the grain size distribution test and reduces the time required, also CiviLab provides high quality reports and archives them properly

For the hydrometer test, CiviLab uses the following standards:

  • ASTM D 7928;
  • ASTM D 422;
  • NF P 94-057;
  • ISO 17892-4.

In the Grain size test you can use CiviLab to:

  • Plot the particle size curve with several methods (You can draw multiple curves in the same sheet);
    • Linear;
    • Culic spline;
    • Culic spline Akima;
    • Culic spline Pchip;
    • B-spline.
  • Calculate the fineness modulus according to the standards:
    • NF EN 12620;
    • ASTM C 136;
    • XP P 18-540;
  • Calculate the Coefficient of uniformity (Cu) and curvature (Cc);
