What is the difference between fine grained and coarse-grained?

Coarse-grained materials or systems have fewer, larger discrete components than fine-grained materials or systems. A coarse-grained description of a system regards large subcomponents. A fine-grained description regards smaller components of which the larger ones are composed.

Which soil has highest void ratio?

Loose soils have relatively high volume of voids so in the equation they have high value of the numerator and hence higher value of void ratio.

Why is coarse-grained soil more permeable?

The degree of permeability of compacted soil relates to the rate at which water moves through soil after it has been compacted. If a coarse-grained soil, after compaction* contains large continuous pores, it transmits water rapidly and is said to have a high permeability.

Is coarse more fine than permeable?

The coarse sand had the greatest calculated permeability for all liquids, the fine sand calculated permeability was intermediate for all liquids, and the soil had the lowest calculated permeability.

Why is a fine grained structure harder than a coarse grained structure?

The movement of dislocations is hindered by grain boundaries. The more grain boundaries there are the more difficult it is for the dislocations to move and for the metal to change shape. A fine grained metal is therefore stronger than a coarse grained metal.

What is the difference between coarse grained multithreading and fine grained multithreading?

The main difference between Fine Grained and Coarse Grained Multithreading is that, in fine grained multithreading, the threads issue instructions in round robin manner while in coarse grained multithreading, the threads issue instructions until a stall occurs.

What is fine-grained soil?

Fine-grained soils have 50\% or more material passing the No. 200 sieve. Engineering properties such as strength and compressibility of coarse-grained soil are governed by the grain-size of the particles and their structural arrangement. Fine-grained soil is impermeable due to its small particles size.

Why is void ratio important?

The minimum void ratio is an important parameter for evaluating soil properties. The more irregular the particle shapes, the more complicated the contact between particles, the more the void existed between the particles, and the larger the minimum void ratio.

What is fine grained soil and coarse grained soil?

Coarse-grained soils have 50\% or less material passing the No. 200 sieve. Fine-grained soils have 50\% or more material passing the No. 200 sieve. Engineering properties such as strength and compressibility of coarse-grained soil are governed by the grain-size of the particles and their structural arrangement.

Are suitable for fine grained soil?

Silt and clay are fine grained soils. All fine grained soils exhibit, to some degree, the properties of plasticity and cohesion. Gravel makes up the larger fraction of the coarse grained soils. Most gravels have a distinctly rounded shape and are smooth to the touch.

Which of the following properties are more in fine grained and coarse grained structures?

Which of the following property will be more in fine grained structure? Explanation: Finer the grain size (lower the grain size), more is the number of grain boundaries, thus more is the yield strength, thus more is the ductility.
