Your single point of reference for all your Geotechnical Inquiries


This program reduces the data from sieve and hydrometer tests. From 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.
