Is it always possible to determine the coefficient of uniformity and coefficient of curvature for all types of soils?
Determining the Coefficient of Uniformity (Cu) and Coefficient of Curvature (Cc) only has meaning when classifying coarse-grained soils, i.e. clean gravels (GW or GP) and clean sands (SW or SP) having more than 50% of material larger than No. 200 sieve with less than 5% fines. Gravels and sands with more than 12% fines (GM, GC, SM, SC) are distinguished using Atterberg limits. There would be no reason to determine these coefficients for fine-grained soils (i.e. clay, silt and peat).
What is the Difference between coarse grained and fine grained parallelism?
Granularity refers to the ratio of actual computation to the amount of communication required by a parallel system. A fine-grained system will do a small amount of computation before transferring data/results. A coarse-grained system will do a relatively large amount of computation before reporting back.
What is hydraulic conductivity of soil?
This depends on the soil! Cohesionless coarse grained soils with high gravel contents may have high hydraulic conductivity on the order of 1 to 1x10-1 m/s. Mixed sands and gravels are on the order of 1x10-1 to 1x10-3 m/s. Finer sands approximately 1x10-3 to 1x10-4, and fine grained soils such as silty sands may be in the range of 1x10-5 to 1x10-7 m/s. Very fine grained cohesive clay soils have very low hydraulic conductivity values ranging from 1x10-7 to 1x10-13 m/s.
Simple experiment to compare steel and cast iron?
A steel specimen would give a longer or continuous sound when beaten by a hammer. This is due to the malleable nature of the material. In other words, sound takes longer to travel in a coarse-grained material. Whereas cast iron specimen gives sound of shorter duration. This is due to the brittle nature of the material. In other words, sound takes shorter to travel in a fine-grained material.
Fine grained material used in cement?
The fineness of cement has an important bearing on the rate of hydration and hence onthe rate of gain of strength and also on the rate of evolution of heat. Finer cement offers agreater surface area for hydration and hence faster the development of strength.
Why liquid limit and plastic limit are important?
The Atterberg limits of a soil are used as an integral part of several engineering classification systems to characterize fine-grained soils. Also these limits are used directly in specifications for controlling soil for use in fills, and in semi-empirical methods of design. A wide variety of engineering properties of soils have also been correlated to the liquid limit, plastic limit, and plasticity index of soils (i.e. Compressibility, Permeability, and Strength).

coarse grained
Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
Is obsidian course grained?
fine grained
What is meaning the grain of the rock?
fine grained or coarse grained
Is Lime Stone coarse grained or fine grained?
it is fine grained because the grains that make it up are to small to see
Is coal fine grained?
Coal is fine grained, lack of visible texture.
How does fine grained igneous rock form?
when the lava cools quickley it is fine-grained
