no gravel (material larger than No. 4 sieve). Step 3: Prepare adjusted gradation curves for base soils that have particles larger than the No. 4 (4.75 mm) sieve. • Obtain a correction factor by dividing 100 by the percent passing the No. 4 (4.75 mm) sieve. • Multiply the percentage passing each sieve size of the base soil smaller than No. 4 ...
The fineness modulus of sand is a measure of the average particle size of sand particles. It is calculated by adding the cumulative percentages of sand particles retained on each of a specified series of sieves and dividing the sum by 100. The fineness modulus of sand ranges from 2.2 to 3.2. In other words, the fineness modulus of sand is a ...

Sieve analysis. Sand is characterized by a sieve analysis. A sieve analysis is performed using a set of stackable mesh trays (sieves) with hole diameters starting large and getting progressively smaller (9.5 to 0.075 mm). The sieves have numbers that correspond to the number of holes per inch in the mesh for sieves #4 and finer.
Sieve analysis is a method that is used to determine the grain size distribution of soils that are greater than 0.075 mm in diameter. It is usually performed for sand and gravel but cannot be used as the sole method for determining the grain size distribution of finer soil. The sieves used in this method are made of woven wires with square ...

The Sieve and the Sand. Once as a child he had sat upon a yellow dune by the sea in the middle of the blue and hot summer day, trying to fill a sieve with sand, because some cruel cousin had said, "Fill this sieve and you'll get a dime!". And the faster he poured, the faster it sifted through with a hot whispering.
