Coarse-Grained Soils | Fine-Grained Soils |
The coarse-grained soil particles can be seen with our naked eye. | The fine-grained soil cannot be seen with our naked eye. |
The coarse-grained soil can be identified on the basis of the particle size of the grain size of the soil. | The fine-grained soil is identified on the basis of the plasticity of the soil. |
The coarse-grained soils have 50% or less material which passes through the sieve number 200. | The fine-grained soil have 50% or more material which passes through the same number 200 |
The load-bearing capacity of the coarse-grained soil is good. | The fine-grained soil has less load-bearing capacity. |
There is no change in the strength of coarse-grained soil with respect to the change of the water content of the soil. | There will be the change in the strength of the fine-grained soil with respect to the change in the water content of the soil. |
The coarse-grained soil feels gritty when it is touched by the hand. | The fine-grained soil feels smooth and sticky when touched by hand. |
The coarse-grained soil does not retain water and has more permeability. | The fine-grained soil has very less permeability and it can retain water. |
There will be no change in the volume of the coarse-grained soil with a change in the moisture content. | There will be a change in the volume of the fine-grained soil with a change in the moisture content. |
The size of the coarse-grained soil particles varies from 4.75 mm up to 75 microns. | The size of the fine-grained soil is less than 75 microns. |
The coarse-grained soil has less void ratio. | The fine-grained soil has more void ratio. |
