This program reduces the data from sieve and hydrometer tests. From your the test data the software calculates fineness modulus, percentage diameters (e.g., D10, D30 and D60), coefficient of uniformity (Cu) and curvature (Cc), and fractional components (e.g., the percentage of cobbles, gravel, sand, silt and clay in the material tested). Fractional components can be calculated based on the cobbles/gravel/sand/silt/clay particle sizes dictated by the user's choice of ASTM, AASHTO, Wentworth, Burmister or Australian (AS 1726) standards.
If you're running other geotechnical laboratory tests in addition to sieves and hydrometers, be sure to check out one of our soil testing suites:

Features
- ASTM C136 • ASTM D1140 • ASTM D6913 • ASTM D7928 • AASHTO T 11 • AASHTO T 27 • AASHTO T 88 • AASHTO T 311 • ASTM D422 (standard retired, but still supported) • State DOT Standards • Australian Standard 1141.11
- Sieve tests can utilize multiple sample splits
- "Sieve nest" lists simplify data entry by pre-filling in the list of sieves used for a test
- The software can check for sample conformance with up to three material specifications
- Specifications are stored in a program-maintained database for reuse on subsequent tests
- A composite particle size distribution curve is built from sieve and hydrometer tests performed on a single split sample
- Fractional percentages (e.g., percent gravel, coarse, medium and fine sand, etc.) are calculated and reported. Percentages can be calculated using the particle size divisions specified by ASTM, AASHTO, Burmister, Wentworth, CanSIS, BS 5930 and others.
- Diameters at various retained percentages (e.g., D10, D30, D60), coefficients of concavity and uniformity (Cc and Cu) fineness modulus results are automatically calculated from the particle size distribution curve
- Curves may be plotted on semi-log, Wentworth (Phi), .45 power, log(size) vs. probability or linearly-scaled charts
- Charts can also include specification envelopes or specification bars indicating conformance to user-entered specifications
