Why falling head test is not suitable for coarse grained soil such as gravel?
The falling head test is not suitable for coarse grained soils like gravel because the test requires a fine-grained soil that can create a seal at the base of the standpipe. Coarse grained soils like gravel do not form a tight seal, which can lead to inaccuracies in measuring the permeability of the soil sample. The test works best with fine-grained soils with low permeability.
What is loess made mainly of?
Loess is mainly composed of fine-grained sediment, such as silt and clay, that has been transported by wind and deposited over time. Its mineral composition can vary depending on the source material and the processes involved in its formation.
Is coal fine grained?
Coal is fine grained, lack of visible texture.
Is limestone coarse grained or fine grained?
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
What rock is cemented mud or clay or silt?
The rock that is cemented mud, clay, or silt is called shale. Shale is a fine-grained sedimentary rock composed of compacted and hardened mud or clay particles.
Is clay compacted dense mud?
No, clay is a deposit made up of hydrous aluminum phyllosilicates. Mud is i mixture of fine grained minerals.
Is shale fine-grained or coarse-grained?
shale is fine grained
What is the difference between clay and shale?
Clay is a type of fine-grained natural soil material that is composed of mineral particles smaller than silt. Shale is a fine-grained sedimentary rock that is formed from the compaction of clay, silt, or mud over time. Essentially, shale is the hardened form of clay.

What is the size of clay soil?
clay defined as fine grained soils-size of soils is passing 2mm seive with 10% soils retained on a 2mm seive.

Is obsidian course-grained or fine-grain?
fine grained
What is the difference between fine-grained and coarse-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
What is the difference between coarse-grained and fine-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
What is a fine-grained detrital rock that breaks into chunks or blocks?
A fine-grained detrital rock that breaks into chunks or blocks is likely a shale. Shale is composed of clay minerals and silt-sized particles compacted together. It tends to break along bedding planes, forming flat chunks or blocks.
Is shale coarse grained?
Shale is actually fine-grained, composed of very small particles such as clay and silt that have been compacted over time. It often has a smooth, layered appearance due to the arrangement of these tiny particles.
Is marble fine grained or coarse grained?
coarse grained
