The following results were obtained from sieve analyses of two soils:
Hydrometer tests of these soils give the following results: Soil A, % finer than 0.002 mm 5 48%; Soil B, % finer than 0.002 mm 5 2%.
(a) Plot the gradation curve for each soil on the same graph.
(b) How much coarse-grained and fine-grained soils are in each soil?
(c) What are the percentages of clay and silt in each soil?
(d) Determine D10 for each soil.
(e) Determine the uniformity coefficient and the coefficient of concavity for each soil.
(f) Describe the gradation curve (e.g., well graded) for each soil.
