Classification of soil based on its composition:
- Gravel: Coarse-grained soil with particle size greater than 4.75 mm.
- Sand: Coarse-grained soil with particle size between 4.75 mm and 0.075 mm.
- Silt: Fine-grained soil with particle size between 0.075 mm and 0.002 mm.
- Clay: Fine-grained soil with particle size less than 0.002 mm.
Given that the soil mass contains 40% gravel, 50% sand, and 10% silt, it can be classified as a gravelly silty sand. This is because the soil contains a significant amount of gravel and sand, with a smaller amount of silt.
Coefficient of uniformity:
- The coefficient of uniformity (Cu) is a measure of the degree of uniformity of the particle size distribution of a soil sample.
- It is defined as the ratio of the particle size that is 60% finer than the maximum size to the particle size that is 10% finer than the minimum size.
- The coefficient of uniformity is used to classify soil into different types based on its particle size distribution.
Based on the given information, the coefficient of uniformity of the soil cannot be determined. This is because we do not have information about the particle size distribution of the soil within each of the gravel, sand, and silt fractions. Therefore, option (d) is incorrect.
However, we can still make some general observations about the coefficient of uniformity based on the soil classification. Since the soil is classified as gravelly silty sand, we know that it contains a significant amount of gravel and sand, with a smaller amount of silt. This suggests that the coefficient of uniformity is likely to be greater than 60, since the soil contains a significant amount of coarse-grained particles. Therefore, option (c) is the correct answer.
- Gravel: Coarse-grained soil with particle size greater than 4.75 mm.
- Sand: Coarse-grained soil with particle size between 4.75 mm and 0.075 mm.
- Silt: Fine-grained soil with particle size between 0.075 mm and 0.002 mm.
- Clay: Fine-grained soil with particle size less than 0.002 mm.
