Effective Grain Sizes
The grading curve results in essential curve parameters that require a prior determination of d10, d30 and d60.
|
d10 = |
Particle size, of which 10 % by weight are finer than d. |
|
d30 = |
Particle size, of which 30 % by weight are finer than d. |
|
d60 = |
Particle size, of which 60 % by weight are finer than d. |
By means of these details the curve parameters CU (coefficient of uniformity) and CC (coefficient of curvature) can be calculated to describe the particle size distribution.
