Problem 2 A sieve analysis was performed on four soil samples, A, B, and C, and the result of each respective test is provided in Graph 1 below. Analyze the grain size distribution curves, and determine the general characteristics and contents of each soil sample tested. Be sure to include the following: a) Major constituent b) Gradation characteristics, include Cu or Cc if applicable c) Soil type and gradation description 100 80 60 60 Percent Finer (%) 40 40 Grain Size Distribution A B 20 20 10 0.1 0.01 Particle Size (mm)

I need the correct answer and as soon as possible please

The results of a sieve analysis are reported in table 1. The total weight of the sample was 500 g. Plot the gradation curve, calculate CU and Cz, and use these coefficients the determine whether the soil is well graded or poorly graded. Table 1.
