C-6. Sand Filter

2020-11-23 · It is recommended to grade pervious areas to drain away from sand filters and to limit the drainage area of a sand filter to five acres or less. Sand filters will function much better when the drainage area is highly built-upon because this will greatly reduce the amount of fines that reach the sand filter and potentially cause clogging.

What is Fineness Modulus of Sand (Fine Aggregate) and ...

Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.

Soil Mechanics: LESSON 4. Classification of Soil

The sand is sub-divided as Coarse Sand (4.75 mm to 2.0 mm), Medium Sand (2.0 mm to 0.425 mm) and Fine Sand (0.425 mm to 0.075 mm). Soil with particle size less than 0.075 mm is called Fine-Grained soil (Silt or Clay) and soil with particle size in between 80 mm to 0.075 mm is called Coarse-Grained soil.
